SetBackgroundColor

The SetBackgroundColor method sets color for transparent background.

SetBackgroundColor Color

Parameters

Color: Text string containing hexadecimal color value "RRGGBB".

Note

This method sets the color for transparent entry in the color table. Usually it is called before creating of the first animation track. Add subsequently created tracks having transparency will use this color to draw transparent areas.
This method is important if you are going to resize existing animation to new one keeping transparency information. To avoid a halo on the edges of transparent areas in the resized image you need to set background color closely (or equal) to color of concrete background where the resized image will be shown. For example, if you are going to show resize gif on the light blue background then you can make a call like
SetBackgroundColor "bbbbff"
before first AddTrack or Read

Example

See the Resize method.
