    Introduction

    Unlike Microsoft Office, the OpenOffice.org program has an excellent tool for

    creating vector drawings and editing graphics called Open Draw. This program

    is halfway between poorer programs like Paint and top-of-the-range applica-

    tions like GIMP and Photoshop. Open Draw is easy to use and offers users

    several advanced features. In this introductory section, we will describe its key

    features, which include:

    • Creation�and�formatting�of�a�wide�range�of�objects. Open Draw offers

    the possibility of working with and formatting 2D and 3D graphics, lines,

    text etc.

    • Integration�with�other�applications. Open Draw's drawing features and

    utilities can also be accessed from Open Writer, Open Calc and Open Im-

    press, allowing us to use them directly in any OpenOffice.org document.

    • Full�text�formatting. Just as the drawing tools are available in other com-

    ponents of OpenOffice.org, most of the features of Open Writer can be

    accessed from Open Draw. This means that we can use styles with the ob-

    jects, lines and texts that we create.

    • The�FontWork�utility We can use this to create stunning text effects, such

    as curves and distortion.

    • Inserting�files,�OLE�objects�and�graphics. We can insert a wide range

    of file formats in Open Draw, as well as OLE objects such as charts and

    spreadsheets.

    • File�formats. Besides being able to import and export many graphics for-

    mats, we can also export Open Draw and Open Impress documents to

    HTML format. We can also export to the EPS and SVG formats, the latter

    being an XML-based scalable vector graphics format.

    • Creating�basic�objects If we don't want to complicate matters and just

    want to do simple drawing operations, the standard polygons are very easy

    to use.

    • Special�effects. Special effects and filters can be applied to graphics created

    with the program.

  • GNUFDL • PID_00148481 6 Open Draw. Drawing with OpenOffice.org

    • Colour. We can control all aspects of colour and apply different conver-

    sions, such as greyscale or black and white. Certain colours in an image

    can also be swapped for others.

    The main aims of this unit are:

    1) to familiarise students with the use of the key drawing functions of Open

    Draw by creating a sample document, and

    2) to describe the process of creating and formatting the most common draw-

    ing objects.

  • GNUFDL • PID_00148481 7 Open Draw. Drawing with OpenOffice.org

    1. Basic use of the program

    Open Draw can be launched from any OpenOffice.org application by selecting

    the File ­> New ­> Drawing menu option.

    Tips can be very useful for learning about the different features of the program.

    Tips are displayed for each of the labels and buttons on the screen. You can

    enable or disable this option using the Help ­> Tips menu option.

    1.1. The working environment

    As with the other applications, if you need help with a dialog box or window,

    you can always click on the Help button or press F1.

    Figure 1. The Open Draw working environment

    We will now describe the diverse elements in the program's workspace:

    • The Menu�bar contains the various actions that can be carried out globally

    across the OpenOffice.org program and those that are specific to Open

    Draw.

  • GNUFDL • PID_00148481 8 Open Draw. Drawing with OpenOffice.org

    • The Function�bar indicates the full path of the file being edited and pro-

    vides a shortcut to the program's global features.

    • The Object�bar is used to control object attributes. When we work with

    different objects, the Object bar will change to display the attributes of

    the selected object. For example, if we are using text tools, the Object bar

    will display the text formatting tools.

    • The horizontal�and�vertical�rulers indicate the dimensions of the page

    and the objects on it. The units of measurement units of these rulers can

    be changed very quickly by right-clicking on them.

    • The Main�toolbar, positioned vertically down the left-hand side of the

    document, gives users quick access to the most common functions. It can

    be used to create and align objects, insert new objects and much more. To

    display all of the features of the buttons on this bar with submenus, hold

    down the mouse button as you click on them.

    • The Options�bar can be used for accurate customising of the position of

    text, lines and objects in the drawing, as well as some more advanced

    options.

    • The Color�bar is used to select the colour of an object as you would with

    the Object bar but is more intuitive and much quicker.

    • The Status�bar , located at the bottom of the screen has a number of func-

    tions, which include displaying page numbers, applying page styles (by

    right-clicking on Standard), changing the zoompercentage and changing

    the default type of text selection.

    We have just described the Open Draw workspace but the program has a sec-

    ond workspace for working with graphics. In this workspace, the Object bar

    can be used to make a number of changes to an image, such as adjusting

    colours, converting it to black and white or rotating it.

    Figure 2. The Open Draw working environment for images

    If you click on the magic wand button to the left of the Object bar, you will

    access the program filters that can be applied to the image you are editing.

    Another very useful Open Draw tool is the eyedropper, which can be used to

    replace a colour in an image with another of your choice. To use this feature,

    select the Tools ­> Eyedropper main menu option.

    Figure 3. Eyedropper dialog box

  • GNUFDL • PID_00148481 10 Open Draw. Drawing with OpenOffice.org

    Once inside the Eyedropper dialog box, click on the Eyedropper button in the

    top left of the dialog box, then click on the first colour you wish to replace and

    enter the tolerance in this same dialog box. It is best to play it safe by starting

    with a tolerance of 10% and working your way up if the results are not to your

    satisfaction. In the Replace with field, select the colour you want to replace the

    original one with. Finally, click on the Replace button to change the colour.

    1.2. Creating a sample drawing

    We will now create a sample drawing to discover the basic features of the

    program and familiarise ourselves with its workspace. Follow the steps below

    closely for this:

    1) Launch OpenOffice.org and create a new drawing document by selecting

    the File ­> New ­> Drawing option from the main menu. This will open a new

    window with a blank drawing document.

    2) In the program's status bar, double-click on the value indicated as the per-

    centage of zoom. This will bring up the document scaling settings dialog box.

    Enter a Variable scale of 90% here.

    3) Click on the Rectangle button on the Main toolbar and hold down the

    mouse button until the Rectangles bar appears. Click on the filled rectangl
