Reads data from the supplied stream.
int VpeStreamRead(
VpeHandle hStream,
BYTE *buffer,
int size
)
VpeHandle hStream
stream handle
BYTE *buffer
pointer to the buffer, to which the data will be copied from the stream
int size
the number of bytes that shall be read
Returns:
The number of bytes read from the stream.
Remarks:
When reading from a stream, which was written by a VPE method, e.g. WriteDocStream() or PictureStream() etc., you need to call VpeStreamSeek(hStream, 0) first before calling VpeStreamRead() in order to reset the internal stream pointer to the beginning of the stream.
