Function Documentation

DWORD ConvertColourToScreenWord (  ColourContext *  cc,
DocColour *  col
)  [inline]
 

Converts the given DocColour into the given screen (RGB) output context for whatever host OS we are running under. This function does NOT include any transparency information in the result.

Date:

Parameters:
cc - An *RGBT* colourContext for screen output [INPUTS] col - The Colour to be converted
- [OUTPUTS]
Returns:
An RGB value suitable for passing to the host OS
  • In this case, an rgb DWORD as used by Windows GDI (0x00BBGGRR)
Notes: Note that to save poking about in the internal DocColour representations, a function is supplied by the ColourContextRGBT class which just happens (!) to suit our needs. However, I've wrapped the call up in this WinOil veneer so that on other OS's it will not be necessary to touch that kernel code (just write equivalent code to go into here)

Parameters:
cc - An *RGBT* colourContext for screen output [INPUTS] col - The Colour to be converted
- [OUTPUTS]
Returns:
An RGB value suitable for passing to the host OS
  • In this case, an rgb DWORD as used by GAVIN (0xTTBBGGRR) NOTE that this word must NOT be passed to Windows GDI, as GDI uses the MS byte in a different manner to Gavin.
