GpiQueryBitmapDimension

This function returns the width and height of a bit map, as specified on a previous GpiSetBitmapDimension function.

Syntax
 rc = GpiQueryBitmapDimension(hbm, psizlBitmapDimension); 

Parameters

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


 * psizlBitmapDimension (PSIZEL) - output : Size of bit map.
 * The width and height of the bit map in 0.1 millimeter units.
 * If not set by GpiSetBitmapDimension, zeros are returned.

Return Code

 * rc (BOOL) - returns : Success indicator.
 * TRUE : Successful completion
 * FALSE : Error occurred.

Errors
Possible returns from WinGetLastError
 * PMERR_INV_HBITMAP (0x207B) : An invalid bit-map handle was specified.
 * PMERR_HBITMAP_BUSY (0x2032) : An internal bit map busy error was detected. The bit map was locked by one thread during an attempt to access it from another thread.

Example Code
This example uses GpiQueryBitmapDimension to return the width and height of a bit map, as specified on a previous GpiSetBitmapDimension call; if successful, it assigns the width to a variable. 
 * 1) define INCL_GPIBITMAPS /* Bit-map functions */
 * 2) include 

BOOL fSuccess; /* success indicator */ HBITMAP hbm; /* bit-map handle */ SIZEL psizlBitmapDimension; /* size of bit map */ LONG lWidth; /* width of bit map */

fSuccess = GpiQueryBitmapDimension(hbm, &psizlBitmapDimension);

/* if successful, assign value of bit-map width */ if (fSuccess == TRUE) lWidth = psizlBitmapDimension.cx;
