Value

Meaning

FADE_OUTER

[$0001] If this flag is set, the fade will be outside the bitmap's region. If this flag is not set, the fade will be inside the bitmap's region.

FADE_DUMPFILL

[$0002] If this flag is set, the dump part of the mask will be filled with the dump color. The FADE_FILLCOLOR_START and FADE_WHITETOBLACK flags determine the dump color. If this flag is not set, the dump part is filled with the crTransparent color.

FADE_FILLCOLOR_START

[$0004] If this flag is set, the dump color is the color used at the start of the fade. The start color may be white or black, based on the FADE_WHITETOBLACK. If this flag is not set, the dump color is the color at the end of the fade. If the FADE_DUMPFILL flag is not set, this flag is ignored.

FADE_WHITETOBLACK

[$0008] If this flag is set, the fade starts with white and changes toward black. If this flag is not set, the fade changes from black to white.

FADE_NOTRANSPARENCY

[$0010] If this flag is set, fill the transparency part with a color other than crTransparency. The color is either the same as the dump color, or its opposite, depending on whether the FADE_TRANSPARENCY_DUMPCOLOR flag is set. If the FADE_NOTRANSPARENCY flag is not set, fill the transparency with crTransparency. If the FADE_DUMPFILL flag is not set, this flag is ignored.

FADE_TRANSPARENCY_DUMPCOLOR

[$0020] If this flag is set, the transparency color is the same as the dump color. If this flag is not set, the transparency color is the opposite of the dump color. This flag is used only if FADE_NOTRANSPARENCY is set
