SYMPTOMS

SetDIBitsToDevice faults inside GDI when passed a 24-bpp Presentation Manager (PM) style device-independent bitmap (DIB) on a device that supports RC_DIBTODEV.

CAUSE

GDI must convert the old style BITMAPCOREINFO structure into a new BITMAPINFO structure before passing it to a driver's RC_DIBTODEV function. If the old style DIB has no color table, GDI will fault as it attempts to append a zero length color table to the end of its temporary BITMAPINFOHEADER.

RESOLUTION

On devices that support RC_DIBTODEV, do the conversion into the new style DIB format for GDI before calling into it when using 24-bpp PM-style DIBs.

STATUS
