Description
Gets data that describes this region.
Syntax
GpStatus WINGDIPAPI GdipGetRegionData(
GpRegion
*region,
BYTE * buffer,
UINT bufferSize,
UINT *
sizeFilled
);
PowerBASIC Syntax
DECLARE FUNCTION GdipGetRegionData ( _
BYVAL region AS
DWORD, _
BYREF buffer AS
ANY, _
BYVAL
bufferSize AS DWORD, _
BYREF
sizeFilled AS DWORD _
) AS LONG
Parameters
region
[in] Pointer to the
Region
object.
buffer
[out] Pointer to an array of
BYTE
values that receives the region data.
bufferSize
[in] Integer that specifies the size, in bytes,
of the buffer array. The size of the buffer array
can be greater than or equal to the number of bytes required to store
the region data. The exact number of bytes required can be determined
by calling the GdipGetRegionDataSize method.
sizeFilled
[out] Pointer to an
LONG
that receives the number of bytes of data actually received by the buffer
array. The default value is NULL.
Remarks
The GdipGetRegionDataSize
method can be used before the GdipGetRegionData
method to determine the number of bytes needed to store the region
data. Then, you can allocate a buffer that is the correct size to store
the region data and set the buffer parameter to
point to the buffer.
