GreGetBitmapDimension

GreGetBitmapDimension renders height and width values for the bit map indicated by hbm.

This function is supported by the graphics engine.

Syntax
GreGetBitmapDimension(hbm, pDimension, pInstance, lFunction);

Parameters

 * hbm (HBITMAP) - input
 * Bit-map handle.


 * pDimension (PSIZEL) - input
 * Pointer to width and height values in 0.1mm units.


 * pInstance (PVOID) - input
 * Pointer to instance data.


 * lFunction (ULONG) - input
 * High-order WORD=flags; low-order WORD=NGreGetBitmapDimension.

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
These are values that have been set by a previous call to GreSetBitmapDimension. They are not used by the system.

Sample Code

 * 1) define INCL_GRE_DEVSUPPORT
 * 2) include 

HBITMAP   hbm;         /*  Bit-map handle. */ PSIZEL    pDimension;  /*  Pointer to width and height values in 0.1mm units. */ PVOID     pInstance;   /*  Pointer to instance data. */ ULONG     lFunction;   /*  High-order WORD=flags; low-order WORD=NGreGetBitmapDimension. */ BOOL      fSuccess;    /*  Return codes. */

fSuccess = GreGetBitmapDimension(hbm, pDimension,            pInstance, lFunction);
