void firevision::FuseImageContent::decompress	(	unsigned char *	yuv422_planar_buffer,
		size_t	buffer_size
	)

Decompress image data.

This is a utility method which can be used on clients to decompress compressed image payload. Since every time a new decompressor is created and deleted this method can be slower compared to decompressing the data directly in your application so use with care.

Parameters:

yuv422_planar_buffer	an already allocated buffer where the decompressed image will be stored.
buffer_size	size of yuv422_planar_buffer in bytes. Must be big enough to store a YUV422_PLANAR image of the image dimensions of the compressed data.

unsigned int firevision::FuseImageContent::format ( ) const

Get image format.
