Detecting screen mode

[arti]

Is there a system function that would detect current screen depth and color order (RGB/BGR) ?

You can use GetVPModeID to get the mode ID of the current screen and then for example p96GetModeIDAttr to find out the pixel format. CGX should have a similar function, I just don't remember it right now.

OS screen I assume? RGB/BGR implies a graphics card.

Look at cybergraphics.library/LockBitMapTags()
(p96 should emulate this?)

int pixelFormat; 
int handle = LockBitMapTags(screen, LBMI_PIXFMT, &pixelFormat); 
if( handle != 0 ) 
{ 
   switch(pixelFormat) 
   { 
      case PIXMFT_RGB: 
         ...
   }
}
