L_LTPNT_API L_INT L_PntOffsetClipRgn(pPaint, nDX, nDY)
pPAINTHANDLE pPaint; |
pointer to a paint handle |
L_INT nDX; |
x-offset |
L_INT nDY; |
y-offset |
Offsets the paint-clipping region of the device context (DC) and the bitmap.
Parameter |
Description |
pPaint |
Pointer to a paint handle. |
nDX |
The offset in the horizontal direction. |
nDY |
The offset in the vertical direction. |
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
The toolkit will perform the necessary transformations to the offset values, using the current painting transformation values set by calling L_PntSetTransformation. Therefore, the user should provide the offset values without any transformations.
