GreGetBitmapParameters

GreGetBitmapParameters returns, in the buffer addressed by pInfoHd, header information for the specified bit map.

This function is supported by the graphics engine.

Syntax
GreGetBitmapParameters(hbm, pInfoHd, pInstance, lFunction)

Parameters

 * hbm (HBITMAP) - input:Bit-map handle.
 * pInfoHd (PBITMAPINFOHEADER) - input:Pointer to a BITMAPINFOHEADER or to a BITMAPINFOHEADER2 structure where the returned information is stored.
 * pInstance (PVOID) - input:Pointer to instance data.
 * lFunction (ULONG) - input:High-order WORD=flags; low-order WORD=NGreGetBitmapParameters.

Return Code

 * fSuccess (BOOL) - returns:Return codes.
 * On completion, the handling routine must return BOOLEAN (fSuccess).
 * TRUE Successful
 * FALSE Error
 * Possible Errors Detected: When an error is detected, the graphics engine calls WinSetErrorInfo to post the condition. Reasons for failure of this function include:
 * PMERR_BITMAP_IS_SELECTED
 * PMERR_HBITMAP_BUSY
 * PMERR_INV_HBITMAP
 * Refer to the "Error Explanations" section of the Presentation Manager Programming Reference for further explanation.

Remarks
The header information is returned as a BITMAPINFOHEADER or BITMAPINFOHEADER2 structure and gives details such as the width, height, number of planes, and number of bits per pel.
