Detailed Description

Interface for encoding buffers of image data to JPEG

Member Function Documentation

virtual bool16 IJPEGEncoder::Close ( )

pure virtual

Upon completion, call Close to release the output stream.

virtual bool16 IJPEGEncoder::Open	(	const JPEGWriteOptions &	jpegWriteOptions,
		IPMStream *	iPMStream
	)

pure virtual

Specify the destination stream and JPEG options. This method must be called first.

Parameters

jpegWriteOptions	- IN: JPEG options
iPMStream	- IN: destination stream

virtual bool16 IJPEGEncoder::WriteRows	(	char *	rowBuffer,
		uint32	numberOfRows
	)

pure virtual

Encode the provided buffer of data to JPEG using the output stream and JPEG options specified by the Open method.

Parameters

rowBuffer	- IN: Source data
numberOfRows	- IN: Number of scanlines of image data in the rowbuffer
