public property TCustomImage.Transparent : Boolean
  read FTransparent
  write SetTransparent
  default False;

Description

Transparent is a Boolean property which indicates if the image uses a clear, non-opaque background. The value for the property is used in the PictureChanged method to set the transparency for the bitmap in Picture. Changing the value for the property causes PictureChanged to be called to update the image data assigned to Picture and to repaint the control.

The default value for the property is False.

Use AntialiasingMode to enable or disable use of the rendering technique. Use the OnPaintBackground event handler to render a custom background for the image.
