AT_ERRCOUNT ACCUAPI IG_load_rect_get( LPAT_PIXPOS lpX, LPAT_PIXPOS lpY, LPAT_DIMENSION lpWidth, LPAT_DIMENSION lpHeight );

Arguments:

Name	Type	Description
lpX	LPAT_PIXPOS	Pointer to variable of type AT_PIXPOS to receive X coordinate of load rectangle.
lpY	LPAT_PIXPOS	Pointer to AT_PIXPOS variable to receive Y coordinate of load rectangle.
lpWidth	LPAT_DIMENSION	Pointer to variable of type AT_DIMENSION to receive width of load rectangle.
lpHeight	LPAT_DIMENSION	Pointer to variable of type AT_DIMENSION to receive height of load rectangle.

Return Value:

Returns 0 if successful. Otherwise, returns the number of ImageGear errors that occurred during this function call.

This function does not process image pixels.

Example:

	Copy Code
AT_PIXPOS nXLoadCrop, /* X coordinate of load crop rectangle / nYLoadCrop; / Y coordinate / AT_DIMENSION nWidCrop, / Width of load crop rectangle / nHiCrop; / Height / AT_ERRCOUNT nErrcount; / Returned count of errors */ nErrcount = IG_load_rect_get ( &nXLoadCrop, &nYLoadCrop, &nWidCrop, &nHiCrop );

Copy Code

AT_PIXPOS nXLoadCrop,        /* X coordinate of load crop rectangle  */
nYLoadCrop;                    /* Y coordinate  */
AT_DIMENSION  
    nWidCrop,                /* Width of load crop rectangle  */
    nHiCrop;                /* Height   */
AT_ERRCOUNT nErrcount;        /* Returned count of errors */
nErrcount = IG_load_rect_get ( &nXLoadCrop, &nYLoadCrop, &nWidCrop, &nHiCrop );
