Editing Picture Properties

This task explains how to access and edit raster or vector picture properties.
  • Define a new sheet.
  • Save the logo.tif document on your computer (to do this, right-click on "logo.tif" and choose Save Target As in the contextual menu).
     

  1. Select the Insert > Picture command.

    A dialog box appears, allowing you to browse your disk. 

  2. Select the file "logo.tif" you have previously imported. The image is imported in your drawing.

  3. Right-click the picture and select Properties.

    The Picture tab of the Properties dialog box is displayed.

    You can modify the following properties for the picture:

    • In the Position area:

      • Horizontal: defines the horizontal positioning on the sheet, taking the bottom left corner of the image into account.

      • Vertical: defines the vertical positioning on the sheet, taking the bottom left corner of the image into account.

    • In the Size area:

      • Width: defines the width in millimeters of the picture.

      • Height: defines the height in millimeters of the picture.

      When you modify the size, the scale is automatically modified at the same time.

    • In the Scale area:

      • Width: defines the width in percentage of the picture.

      • Height: defines the height in percentage of the picture.

      • Lock aspect ratio:  enables to keep the ratio between width and height. If it is not checked, the picture might look distorted when modifying only one feature.

    • In the Original Size area:

      • Width: defines the original width of the picture in millimeters.

      • Height: defines the original height of the picture in millimeters.

      • Reset: resets the original size of the picture if one feature was modified.

    • In the Crop from area:

      • Top: defines the top part of the picture to be hidden.

      • Bottom: defines the bottom part of the picture to be hidden.

      • Left: defines the left part of the picture to be hidden.

      • Right: defines the right part of the picture to be hidden.

    • In the Compression area:

      You can compress a picture to a given format, available in the combo box.

      • None: the picture keeps its original size.

      • PNG: the picture is compressed without loss.

        The PNG format is used by default when inserting a picture whatever its original format.

      • JPEG: the picture is compressed in JPEG format, that is with loss.

      • Picture compression properties: you are given the compression rate in percentage and the size of the picture in bytes according to the chosen format once it is saved on your hard drive. The compression rate and picture size vary according to your picture.

        In our example, the compression properties for the logo picture are as follows:

        Format/Properties Compression rate Picture size
        None 100.00% 14.44 KB (14783 bytes)
        PNG 15.33% 2.21 KB (2262 bytes)
        JPEG 15.09% 2.18 KB (2228 bytes)

  4. Modify the properties as required, and click Apply to preview the changes.
  • In case you insert a monochrome picture, it is automatically set to the CCITTG3 format, which is a unique format without loss.
  • Should you need to edit the picture, refer to the Editing Raster Images section.
