Type Default Value Read Only Description
Boolean   False No Whether to save the alpha channel into the output.




This property determines whether the Save method includes an alpha channel in the rendered output.

Only some types of output support alpha. These are:

  • PNG
  • BMP
  • TIFF (Grayscale, RGB and CMYK)
  • Bitmap (via the GetBitmap function)

By including an alpha channel in your output, you can identify areas which are transparent and areas on which no drawing has taken place.
