Remarks

TGIS_Color is a platform independent color definition used by TatukGIS Developer Kernel. It is defined as little endian ARGB.

DWORD
bits 31..24 bits 23..16 bits 15..8 bits 7..0
A R G B

Where:

Symbol Name Min Max Comments
A Alpha 0 255 0 means fully transparent; 255 means solid
R Red 0 255
G Green 0 255
B Blue 0 255

Sample colors:

Hex color Comments
$00000000 Black
$00FFFFFF Pure Red
$00FF0000 Pure Red
$0000FF00 Pure Green
$000000FF Pure Blue
$FF000000 Fully transparent; color has no meaning
$80000000 50% transparent black

Each platform has defined conversion functions to convert to/from the actual platform-specific color definition. See TGIS_FrameworkUtils.
