Specifying diagram properties

You can specify the dimensions of your diagram and a background color or a transparent background. By default, the height and width of the drawing canvas are 5000x5000 pixels. Documents larger than 6000x6000 pixels are scaled down when exported, which could cause some elements to be blurry in the exported document.

Your diagram must be exported in .PNG format to support transparent backgrounds.
  1. From the File menu, click Document Properties.

  2. Specify the diagram size and background color.

    To choose a transparent background, in the list of background colors, choose No Fill .
  3. To prevent automatic saving of your diagram, select the Disable Autosave check box. See Autosaving drafts.
