The UpdateColors function redraws all pixels in a region on the display surface using the colors specified in the given translation table. For each pixel in the region, the function reads the pixel's color index, translates the index, and writes the translated index back to the original position.
A graphics driver must export the GetPalette function if the RC_PALETTE bit is set in the dpRaster member of the driver's GDIINFO structure.
wStartX
Specifies the y-coordinate of the upper-left corner of the region to update.
wStartY
Specifies the y-coordinate of the upper-left corner of the region to update.
wExtX
Specifies the width of the rectangular region to update in pixels.
wExtY
Specifies the height of the rectangular region to update in pixels.
lpTranslate
Points to an array of color indexes.
This function has no return value.
The export ordinal for this function is 26.
