Bitmap Export Dialog Box - Bitmap Options

Transparency

This button duplicates Transparent background on the Palette Options tab. It provides compatibility for CorelXARA
users.

If transparency is enabled the bitmap will be 'transparent' in all areas not covered by a selected object. If the selection has been chosen then this will be only the visible and selected objects. This makes it easy to remove the white background from exported pictures and makes them ideal for publication on the Internet (see Internet Bitmaps Overview).

If you create a transparent PNG file, one of the palette colors is used as the transparency. This means (for example) that a 2 color PNG file contains one color and transparency.

Note that PNG transparency has a different meaning to Xara LX transparency. This process does not take into account any Xara LX transparency applied to objects in the document.

Interlacing

If interlacing
is enabled the bitmap file produced will be interlaced.
