BUG: SetDIBitsToDevice Faults on 24-BPP PM-Style DIBs

Q104334

3.00 3.10 WINDOWS kbprg kbbuglist



The information in this article applies to:


  • Microsoft Windows Software Development Kit (SDK) for Windows versions 3.0, 3.1





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

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.
