Requires: Direct2D.lg32
Returns a long with an ARGB formatted color value.
argb = ARGB(alpha|, red|, green|, blue|)
| argb | : 32-bit integer |
| alpha|, red|, green|, blue| | : byte expression |
In contrast with GDI the Direct2D library uses ARGB formatted colors. Hexadicimal coded as AARRGGBB, representing the values of the Alpha, Red, Green and Blue channel, respectively. For example, 80FFFF00 represents 50.2% opaque (non-premultiplied) yellow. The 80 hex value, which is 128 in decimal, represents a 50.2% alpha value because 128 is approximately 50.2% of the maximum value of 255 (FF hex).

The GB Direct2D library defines Direct2D ARGB color constants for many colors. The names of these ARGB color constants start with D2C_ and are formatted as D2C_Colorname.
