property EnableAlphaChannel: Boolean;
If EnableAlphaChannel is True, ImageEn uses the alpha channel to display the image.
Some formats like Gif, Png, Tiff, Ico, Cur and Tga contain an alpha channel that specifies the image's transparency.
The alpha channel is stored in the AlphaChannel
property (a TIEBitmap
object) and in TIEBitmap.AlphaChannel
