2.2.2.21 MilSourceModification

  • Article

A MilSourceModification enumeration specifies how pixel colors of an image MUST be interpreted for transparency.

 typedef  enum
 {
   None = 0x00000000,
   IgnoreAlpha = 0x00000001,
   ColorKey = 0x00000002
 } MilSourceModification;

None:  The source is consumed and its inherent properties remain unchanged.

IgnoreAlpha:  The source is consumed as entirely opaque. The transparency properties of the source are ignored.

ColorKey:  The source is passed through a color-keying filter before being consumed.
