Member Function Documentation

virtual bool16 IImageReadData::ReadData (ImageStreamRecord & outImageRecord)
pure virtual

The image record defines the geometry for the data to read, including the area to read (left, top, width, height), the bytewidth for the specified buffer, the plane to read (if planar data), as well as the buffer into which the data should be read.

Parameters
outImageRecordIN/OUT Defines dimensions for image, as well as data buffer
Returns
kTrue if read is successful, else kFalse
