Type Default Value Read Only Static Description
Boolean false No No Whether to use the alpha channel.

Some file formats, such as PNG, allow an alpha channel to be exported to provide transparency. If you want an alpha channel in your saved image this value must be set to true. The alpha channel is derived from the alpha values in the canvas you are exporting.

This is different from Transparency, which controls transparency when the image is imported.

It's best to set this property to true only when exporting to formats that actually support transparency. Otherwise leave it as false.
