Libre draw how to change standard shapes. LibreOffice Draw Basics

Today we will look at the basic techniques of working with LibreOffice Draw on the example of creating a flowchart of the algorithm for a simple computer program.

A program for creating vector images is almost the least popular in the arsenal of the average office suite user. However, this does not mean that you will never need it anywhere. It came in very handy for me for drawing various flowcharts: other graphic editors do not always have the necessary set of convenient tools, or they do, but they require much larger gestures for further insertion of an image into documents and tables.
Let's start simple. Open Draw: to do this, either select New-> Picture Draw on the LibreOffice start screen or the shortcut of the program itself.

To master the basic techniques, we will draw a small block diagram of the program algorithm for determining the larger of the two numbers entered from the keyboard. It will include the following operations: entering numbers -> comparing them -> displaying the result on the screen.

Turn on immediately grid display(it is convenient to use it to control the size of blocks and align them relative to each other) - menu item View-> Grid-> Show grid. And change sheet scale 100%: set the slider in the lower right corner of the screen to the desired value, or change it in the View-> Scale ... menu item.

Symbols will be chosen according to GOST 19.701-90 (ISO 5807-85) “Unified system of program documentation. Schemes of algorithms for programs, data and systems. Symbols and rules of implementation ", since it is it that is usually given to schools (naturally, in a simplified version) and is required in universities.
The block diagram always starts with terminator- an ellipse denoting the exit to the external environment and the entrance from the external environment, including the beginning or end of the program. Place it on the sheet: LibreOffice Draw has a separate set of objects for forming flowcharts - we need the button Diagrams-> Flowchart: the completion sign on the Drawing panel at the bottom of the window:

Click on it, place the cursor at the point where the upper left corner of the object will be located, and stretch the shape to the desired size. Let's say it is 3 grid steps high and 8 long.
Now we will bring the terminator to the form recommended GOST 19.003-80 "Schemes of algorithms and programs. Conventional graphic designation "(at the moment it has been replaced by the above-mentioned GOST 19.701-90, but due to the fact that it contains clearer recommendations on the appearance of blocks, it is periodically referred to): change the height of the block to 2 steps, and the length to 6. Make the background of the shape is white, and the stroke is black: menu item Area ...-> Fill-> Color-> White, menu item Line ...-> Color-> Black.

In order not to repeat the work of changing the color scheme of the shapes every time, do it right away through the main Format menu, and not through the context menu that is called for each shape separately.

Let's add a text to the terminator - double-click on it with the mouse button, press the Text () or F2 button, having previously selected it, and add the caption "Beginning". We get:

So that in which case it would not be excruciatingly painful for the accidentally missing work, save the picture under the name "Comparison of numbers" algorithm:

Now we need to prompt the user to enter two numbers. For this we need the symbol Display... Add it from the same Scheme set, change the proportions to the recommended ones (length = 1.5 * width) and enter the text that will be displayed on the screen:

Similarly, we will add elements to the block diagram Manual input and Solution and also duplicate Display and Terminator(select the desired shape, select the Edit-> Duplicate ... menu item and specify the required number of copies). You get the following blank:

Obviously there is not enough between objects connecting lines... They differ from regular lines and arrows in that they attach to the connection points of objects and move with them, changing their size as needed. There are four types of such lines - standard, bent, straight and smoothed curves (from top to bottom):

To bind a line to the objects that it connects, you need to select its type in the Draw panel and click on it. Then the connection points that all objects have will become visible. Then you need to position the cursor at the starting point of the line and attach it to the point where it should end. In our case, for the first part of the algorithm, a Straight connecting line is suitable:

For a Manual Entry object, the bottom connection point is above the line that delineates it. To make the connection look neat, select the connecting piece and move its beginning below:

For the second part of the algorithm, which contains a condition, it is more convenient to use a folded connecting line with an arrow at the end. It has two additional points of inflection that allow you to turn it in the desired direction - for this, you just need to pull on them:

Four such lines are required. Also next to lines coming out of the object Solution it is customary to make signatures illustrating its logic. Use the Text button again, but this time not for the shape. After clicking on it, place the cursor where the text should be located, and write "YES" there:

Similarly, add the comment "NO" above the opposite line:

The algorithm is ready; all that remains is to save it.
In conclusion, I would like to draw your attention to the fact that each host may have their own requirements for the implementation of nuances that are not directly described in GOST. For example, someone requires that all lines falling under the condition end with arrows, someone requires that the junction of two or more lines be indicated by a dot, etc. Arguing, even armed with GOST, is usually useless. Just be patient and tweak your regular template to suit your specific needs.

Stages

lesson

I. Organizational and motivational stage

Greetings, fixing the absent.

Today we will continue to explore graphic editors. This is a very interesting topic. In previous lessons, you have already heard about vector graphics. Today we will look at graphic editors with the help of which vector images are created. Practical work awaits you, during which you will learn how to use the basic tools of a graphic editor and create the simplest images.

II. Updating basic knowledge

Let's remember what you talked about in previous lessons.

What types of computer images are you aware of?

Raster and vector

How is a bitmap obtained?

A bitmap is created using differently colored dots - pixels that form rows and columns. Each pixel can accept any color from a palette containing tens of millions of colors, therefore bitmaps provide high accuracy in color and halftone reproduction.

What is special about bitmaps?

Bitmaps are very sensitive to scaling (enlargement or reduction). When reducing the bitmap, several adjacent points are converted into one, so the sharpness of small image details is lost. As it increases, the size of each point increases and a stepped effect appears that can be seen with the naked eye.

How are vector images generated?

Vector images are formed from objects (point, line, circle, rectangle, etc.), which are called graphic primitives. For each primitive, coordinates are set, as well as a color. That is, each such object can be mathematically described.

What is the main advantage of vector graphics?

The advantage of vector graphics is that vector graphics can be enlarged or reduced without loss of quality. This is possible, since the scaling of images is performed using a simple multiplication of the coordinates of the points of the graphic primitives by the scaling factor.

III. The stage of assimilation of new knowledge and methods of action

We have recalled the main issues related to computer graphics. Now let's figure out what vector graphics editors are.

Vector graphic editors

Vector graphics editors are used to create pictures, diagrams and drawings using graphic primitives. A vector graphics editor can be viewed as a graphic designer that allows you to build an image from individual objects (graphic primitives).

Vector graphic editors include a graphic editor built into Microsoft Office Word. It is on his example that we will get acquainted with vector editors.

The vector image is easy to edit, since each graphic primitive exists as an independent object. You can move this object, change its size, color and transparency.

Object layers.

Each graphic primitive is drawn on its own layer, so drawings are made up of many layers. Graphic primitives can be superimposed on each other, while some objects can obscure others. For example, if the sun was drawn first and then a cloud was drawn on top of it, then the cloud layer would be on top of the sun layer and the cloud would obscure the sun.

It is very convenient that the vector graphics editor allows us to change the visibility of objects by changing the order of the layers in the picture. To do this, reorder operations are used, which allow you to move the selected object to the front (to the topmost layer of the picture) or to the back (to the bottommost layer of the picture), as well as one layer forward or backward.

Another feature of vector editors is to change the degree of transparency for each object (image layer). The degree of transparency is indicated as a percentage from 0 to 100%. If the transparency of the layer is zero, the object drawn on the layer below will not be visible. On the contrary, with 100% transparency, it will be fully visible.

Grouping of objects.

In the vector editor, individual graphic primitives can be converted into a single object (grouped). With this new object, you can perform the same actions as with graphic primitives, that is, move the object, change its size, color and other parameters. Alternatively, you can split an object consisting of several objects into independent objects (ungroup).

For example, an Olympic emblem can be drawn using five different colored circles. Then, by grouping them into one object, you can change the size, proportions and color of the entire Olympic emblem.

Do you know what the 5 rings mean in the Olympic emblem?

Five intertwined rings of blue, black, red (top row), yellow and green (bottom) colors are a symbol of the five continents united in the Olympic movement. Proposed in 1913 by P. de Coubertin.

For greater accuracy of drawing objects, rulers with divisions are placed horizontally and vertically in the editor window.

A grid is used to align drawn objects horizontally and vertically. You can make the grid visible and also resize its cells.

Basic vector editors

A simple vector graphics editor StarOffice Draw is included in the integrated office application StarOffice, a convenient vector editor is built into the Microsoft Word text editor, you can use the KOMPAS computer drawing system to create drawings and diagrams, CorelDRAW is the most common among professional vector graphics systems.

Today we will get acquainted with the graphics editor built into the Microsoft Word application, which is a vector one.

Before drawing, you need to make sure that the application window has the Draw toolbar.

How do I call the toolbars?

View - Toolbars - ...

Let's take a look at the tools in the Draw panel.

The Draw menu allows you to perform various actions with image objects. For example, you can group, rotate, flip, reorder. Another possibility is the display of grid lines, which allows you to place objects symmetrically, at equal distances, i.e. increases the accuracy of constructions.

The arrow allows you to select and highlight objects.

The Autoshapes menu item provides access to all autoshapes, with the help of which we will build images.

Behind them are the Text Box, Add WordArt, Add Chart, Add Picture, Fill Color, Line Color, Font Color, Line Style, Line Pattern, Shadow Menu, and Volumes icons.

You will need many of these tools for your practical work.

IV. The stage of the initial verification of the understanding of what has been learned

1. Why in vector graphics editors it is possible to change the visibility of the objects that form the picture?

2. In what cases is it useful to use the operation of grouping objects?

3. What vector editors do you know?

4. Name the capabilities of the vector graphics editor, which are its advantages.

V. Phase of applying knowledge and methods of action

Now let's figure it out in practice and learn how to use the drawing tools of a vector graphics editor.

Vi. The stage of correction of knowledge and methods of action

Verification and correction by the teacher of the correctness of the implementation of practical work.

Vii. Homework Information Stage

GOAL OF THE WORK

Learn to build diagrams using libraries of elements for document design. Learn to create presentations for delivering reports.

Duration of laboratory work - 2 hours

1. LIBREOFFICE IMPRESS PROGRAM. MAIN PURPOSE AND OPPORTUNITIES
   1. Creating Diagrams in LibreOffice Draw

LibreOffice Draw is a versatile vector editor for automating the creation of diagrams.

Download the program. By default, the Standard, Lines and Fill panels are located at the top of the window, and the Draw panel at the bottom. The work area contains the Navigator (F5), the Pages panel containing thumbnail images of document pages, the editing area of ​​the current sheet, at the bottom of which there are tabs for switching layers and a list of styles (F11) for text, lines, fills.

First, set the contour line thickness of 0.10 cm for the following shapes in the Lines and Fill panel. From the Schemes group of the Drawing panel, place the elements of the program flowchart into the document.

Set the position and size for the main shapes to size 21.5 cm, for the circle - 1 1 cm, for the shapes of the beginning and end of the program - 2 1 cm.Align the shapes located one below the other by selecting them in a group with the mouse using the contextual command Align / By center. Using the Arrow-End Connector (Horizontal and Vertical) and Arrow-End Straight Connector tools, connect the shapes. Using the Text tool (F2) of the Drawing panel, place the text in the diagram, align the text blocks relative to the shapes using the Align contextual commands. Save the document as "Flowchart.odg"

1. CREATING PRESENTATIONS

Documents used as a poster sequence are called presentations, and a presentation sheet is called a slide (frame). Presentations are visual aids, explanatory materials for a report or lecture. Typically, presentations contain abstracts, figures, tables, diagrams, diagrams, but do not contain the text of the report. It should be borne in mind that tables with numerical values ​​are perceived worse than diagrams when comparing dynamic values. Various fonts are used for easy perception of the text from the sheet and the poster. So, for sheet reading, serif fonts are used (Times New Roman, Cambria, Academia), for a good perception of text on posters and banners, sans-serif fonts with a constant line width (Arial, Helvetica, Calibri) are used.

To prepare a report, you can print several slides on a sheet in the form of abstracts. By default, the presentation is saved in the program format, but it is also possible to save the publication in other formats.

When Impress starts, a window with menus and toolbars, a slide bar, a taskbar, a working window with a template for the first slide is displayed. The working window contains tabs. By default, the Drawing Mode tab is used to design a slide. The Structure mode tab sequentially displays the text of all slides in the form of a numbered list; objects (images, tables, pictures, etc.) are not displayed.

The Notes tab contains a reduced slide view (without the possibility of editing) and a note text entry field. Notes can be used to prepare for the report or to understand the content by people who are not on the report. Abstracts view allows you to select a thumbnail layout to fit multiple slides on a sheet. It can also be used to prepare for a report. The Slide Sorter tab allows you to change the order of slides in your presentation, you can also change the order of slides in the Slides panel, but the tab displays more slides at the same time.

The Tasks pane (toggle display using the View / Task Pane command), located by default to the right of the slide design area, contains the vertical tabs Page Backgrounds, Layouts, Table Design, Effects, Slide Change. Page backgrounds contain a list of templates that contain slide background settings and text styles. Open the university website110 in the Internet browser and save the logo image to the root folder of the virtual disk F: \ using the context menu command under the name KhPI.png (or another type, depending on the image format). Later, you can use any image to create your personal template. In Impress, in the Used in this presentation section of the Page backgrounds tab of the Tasks pane, call the Edit Wizards command from the context menu.

The drawing mode window will switch to the template editing mode, the Background mode panel will appear, on which click the New master button, and then the Rename master button and enter the name "HPI". Select the title frame and increase the left margin by 2–3 cm, and also decrease the size on the left of the outline area below. In the Draw panel (displayed by the View / Toolbars / Draw command) below, select the Rectangle tool and draw a rectangle along the left border of the slide. In the context menu of the created rectangle, select Arrange / Send to Back; Line - Lines tab, Style - Invisible; Region - Region tab, Fill - Color / Blue 9; Position and Size - Position and Size tab,

Position - Positions X and Y at 0 cm relative to the upper left base point, Size - Width: 2 cm, Height: 21 cm relative to the upper left base point, Protection: Position.

Use the Insert / Image / From File command to insert the previously saved image F: \ KhPI.png. If the image, in addition to the logo itself, also contains text, then it must be cropped. Call the contextual image command Crop Image. For example, the original image is 24.873.17 cm in size, the round logo is on the right side of the image (for other sizes and ratios, calculate the dimensions yourself, to check cropping, use the preview area of ​​the command window), in the block

(remove white space in front of the logo) and Right 21.50 cm (remove text), set the Scale to width and height to 100%. Place the cutout logo in the upper-left corner of the window so that the vertical border of the background stripe is in the center of the image. Use the Position and Size contextual command to protect the image position from being changed.

On the Background Mode panel, click the Close Background Mode button.

In the Tasks pane, click the Layouts tab. By default, Impress creates the first slide of the Title layout, slide, and the following slides from the Title, Text layout.

The first title slide contains two areas. Click on the caption "Click to add a title" and enter the title. Hereinafter, synthetic data is used for filling, intended to demonstrate the capabilities of the editor and not reflecting reality. Click on the slide subtitle, enter your last name and initials (or a comma-separated list of students doing laboratory work at the computer), enter "BITM" in the line below.

Insert a new slide after the current one with the Insert / Slide command. By default, a Title, Text layout slide is inserted. The template contains two frames - heading and text. For the created slide, use the Insert / Page Number command to open the Headers and Footers window, on the Slide tab, uncheck all the checkboxes, set the Slide Number checkboxes and Not display on the first slide, click Apply to All.

In the Styles window (F11) on the Presentation Styles tab (the tabs are switched by the buttons in the title bar of the panel window) run the command

Change for Style Background Objects, on the Font tab in the list

Set the typeface to Arial, close the window with the OK button. On the Page Backgrounds tab of the Tasks panel for the current template, run the Edit Wizard context menu command, in the lower right block

Select the slide number area, in the Text formatting panel or in the context menu Type size, set the font size to 18 pt. If you need to place the slide number in the center, change the Slide number area and Footer area in places, set the field row alignment to the center (Ctrl + E), close the editing of the master slide with the Close Background Mode button of the Background Mode panel. The slide number is used when discussing the report to refer to the desired slides. In the list of slides on the left, select the second slide and in the context menu, select New Slide. The Duplicate Slide contextual command creates a new slide and places a copy of the current content on it. Repeat the New Slide command five times. You can assign a keyboard shortcut for the last action redo operation on the Keyboard tab of the Tools / Options window (for example, Ctrl + Shift + Y).

The slide text area, in addition to the template of the marked text, contains an icon-button for inserting a table, diagram, graphic object or video. As you enter text, the icon buttons are automatically deleted, but objects can still be added using the commands on the Insert menu. The text and table have a border that allows you to move their borders. The number and arrangement of blocks is set by templates of the Layouts tab of the Tasks panel. A slide can have local notes added by the Insert / Annotations command (Ctrl + Alt + C). Local notes can be used for explanations when collectively editing presentations; they collapse into colored rectangles with a number at the top of the slide. In addition to user text, local notes contain the date and time of the change. Paste your note on the second slide and type in

its text "Notes to change", collapse the note by clicking outside the note field.

On slide 2, enter the title Work Plan, in the text area, enter bulleted paragraphs: Building a diagram; Collecting data about streams; Basic dependencies; Diagram; Results. On slide 3, enter the title Process Diagram, in the Internet browser, in the Google image search, find the atmospheric vacuum distillation diagram of oil, save it to the F: drive and put it on the slide. You can also copy the URL of the picture with the context command of the Internet browser and, instead of specifying the local file, set the Internet address (convenient for using public network image albums). Usually, the search is performed by bitmap images, and quite often it becomes necessary to redraw the diagram in vector editors (Microsoft Visio, LibreOffice Draw, Inkscape), and then through the clipboard the bitmap object is inserted into the slide.

To describe the scheme, select the layout of the Header blocks, the text above the text on the Layouts tab Tasks, enter the list of devices in the lower text block, disabling paragraph marking (place the cursor at the beginning of the paragraph and press the Backspace button, pressing the marker again). Take a description of the devices from the picture page on the Internet. If you need to create a numbered list, switch the type of marking with the contextual command Bullets and Numbering. Move the text box below if there is free space, and enlarge the image to fill the free space.

If a text block is selected when inserting an image, the loaded image is assigned as the background of the text block and is scaled to the size of the block. To insert a stand-alone image, the selection of a text block must be disabled by clicking outside the text blocks.

Impress allows you to create simple flowcharts in slides (discussed in the Writer section) using the Diagrams and Connector tools in the Drawing toolbar.

On slide 4, enter the heading Data on flows, in the center of the main text frame, click the Insert table icon, in the dialog that opens, specify the Number of columns5, Number of rows5,

fill in the table with the following data:

To place a part of the text in the index, select the characters and press

On slide 5, enter the title Basic Constraints, enter the text in size 24 and formulas (for formulas, also set the base size to 24 in the Math editor using the Format / Size command):

Streaming heat capacity:

	Energy balance:	(all cold	all hot)

Real consumption:

Since formulas are separate blocks, move them with the mouse to the lines of text, insert blank lines if necessary and turn off markers with the Backspace key.

On slide 6, enter the title Chart. In the text area, click the Insert Chart icon button (the window switches to the chart editing mode), execute the Chart Type contextual command of the chart, in the window select the XY Chart / Lines only type, open the window in which the third column is selected with the Chart Data Table contextual command. delete it with the Delete row button, the first should be the column with a blue label, and the second with a red one (if necessary, select the first column of Y values ​​and use the button to move the row to the right). In the heading of the first column, enter "Hol", the second - "Horus". Enter data from the table below. The first column of the table is stored by row numbering, so you don't need to enter it into Impress. In the absence of a constant step (line numbering), to explicitly set the X values, you must use Calc as discussed earlier, and then paste the chart through the clipboard.

Close the data table window and then the chart editing window by clicking on the field outside the chart (double-clicking on the chart activates the chart editing mode again).

On slide 7, enter the title Results, in the main text area, enter the bulleted paragraphs: Saving cold coolant 250 t / year; Saving hot coolant 375 t / year; The payback period is 15 months.

On the Slide Change tab of the Tasks pane, select a transition

Appearance on the right, speed is fast, click the Apply to all slides button.

Save the presentation named "PowerSaver.odp" to a virtual disk. Start showing the presentation using the View / Demo command (F5 or Ctrl + F2), below are the display control keys:

Move to the next slide or animation effect: Left Mouse Button, Spacebar, Right Arrow or Down Arrow, N, Enter, or Page Down.

Move to the previous slide: P, Backspace, Page Up, Left Arrow or Up Arrow.

Go to the first slide: Home.

Move to the last slide: End.

Go to the specified slide: enter the slide number and press enter.

End of show: Esc, minus.

The Pencil Mouse Pointer context menu command allows you to draw on a slide during a presentation (default pencil thickness is normal, color: red). In pencil mode, pressing the left mouse button without moving also moves to the next slide. The context menu commands can be used to change

the thickness and color of the pencil, and erase everything drawn on the slide. Contextual commands Monitor can temporarily hide the display of the slide. Try Pencil mode when presenting. Erase your changes. End the demonstration with the Esc key.

For preparation of the report slides can be printed. Call the File / Print command (Ctrl + P), enlarge the dialog box to enlarge the viewing area, if possible, on the General tab, in the Document list, select Abstracts and Notes in turn, review the result in the preview window, click the Cancel button to close the window.

Self-study assignments:

Create a presentation of at least 6 slides on any topic that interests you. Set your presentation to automatically play slides at 1 minute intervals using animation.

LibreOffice package is positioned by developers as a free analogue of Microsoft Office. The quality of text documents created in LibreOffice Writer is in no way inferior to the quality of Microsoft Word documents. And in some cases, the capabilities of LibreOffice Writer are even broader than those of other text editors. One such case is the use of the Arrows tool, with which you can style the designator lines used in your document. You just need to learn how to use the capabilities of this tool to its full potential.

First meeting

Launch LibreOffice Writer by clicking on the icon on desktop, and look at the lower left corner of the screen. Usually there is menu, which allows you to create objects in a text document from geometric shapes (including lines). If these buttons are not in place, you should check the box in one of the items of the main menu: View -> Toolbars -> Drawing.

Rice. 1. Calling up the menu for drawing in Writer

Drawing in LibreOffice Writer (as in the vast majority of text editors) is carried out by creating vector objects (graphic primitives). And all the necessary drawings and diagrams are created using basic shapes: rectangle, ellipse, block arrows, callouts and stars.

Rice. 2. The drawing menu in Writer. Item "Basic Shapes"

We start drawing. Lines and arrows

The simplest drawing object is a line. V menu Drawing we press the line button and draw it on the screen, simply stretching it with the mouse from start to finish. The method quite simple and accessible to the most novice user.

Rice. 3. First line

Making an arrow out of the line

To make an arrow out of a line, you need to find the "Picture Properties" menu. It is usually located in the upper left corner of the screen, below the Standard pane. But it appears there only when the Line object is selected. If this menu is not in place, then execute the command View -> Toolbars -> Picture Properties.

Now in this menu we are interested in the button "Style of arrows".

Rice. 4. Arrow Style button in the "Picture Properties" menu

It is there that there is everything you need to create all kinds of arrows. Click on the button and see a drop-down menu where all the arrow styles are presented.

Rice. 5. Select the desired arrow style

There is one here problem, on which it is necessary to dwell a little more in detail.

The first thought that the left button in the menu is responsible for the style of the left end of the segment, and the right button for the style of the right one, turns out to be wrong for verification. Actually, the left button defines the line style, and the right one defines it. And the first time it may not be possible to make the arrow "look" exactly where it should be.

In the same menu "Picture Properties" there are buttons with which you can set the desired color and thickness of the arrow; you can move the arrows to the front / back; you can change the anchor of the arrow (to a page, to a paragraph, to a character). In short, you can ensure that the arrow looks exactly as needed in the document (see figure).

Rice. 6. Samples of Arrows Received

Making signatures on the arrows

LibreOffice Writer allows you to bind labels to each of the arrows you create. Such labels will move with the arrow if you change its position.

You can bind an inscription to an arrow by simply clicking on it with the mouse so that a blinking cursor appears in the middle of the arrow. And then you can type any text on the keyboard.

Rice. 7. Inscriptions on arrows

If there is a need to make sure that the signature is "under the arrow" (see the fourth arrow in Figure 7), then, before you start typing, you must press the key once Enter by inserting a blank line.

If the inscription turned out to be upside down (the third arrow in the figure), then you can put it normally by swapping the beginning of the segment and its end.

Adding special effects

In addition to all of the above, LibreOffice Writer allows you to set simple effects for each arrow, which should draw the reader's attention to the desired information.

Right-clicking on the selected arrow, select the item in the context menu: Text.

And in the window that appears, select the bookmark: Animating text.

Rice. 8. We create special effects

It is possible to set one of four dynamic effects (it is a pity that it is impossible to take a screenshot for them). They look pretty unusual, and not every text editor has such tools.

Outcome

Arrows in LibreOffice Writer are a really powerful tool to help you design a text document beautifully.
