SYMPTOMS

The values retrieved by GetBitmapDimensionEx after the color depth changes are not the same as those set by SetBitmapDimensionEx before the color depth changes.

CAUSE

Windows 98 GDI resource handling code reused the dimension values for storing the handle of the logic device and the palette.

RESOLUTION

To work around this problem, store the bitmap dimension values locally in the application and not through the GetBitmapDimensionEx API.
