The length of the data is given in \fIlength\fR. The consumer may be 0, in which case the function should just process the data into \fIimg\fR without telling any consumer about the changes. Note that the decoder must store enough state to be able to continue in subsequent calls to this method - this is the essence of the incremental image loading. -.PP -The function should return without processing all the data if it reaches the end of a frame in the input. -.PP -The function must return the number of bytes it has processed. - -.SH "SEE ALSO" -.BR http://doc.trolltech.com/qimageformat.html -.BR http://www.trolltech.com/faq/tech.html -.SH COPYRIGHT -Copyright 1992-2007 Trolltech ASA, http://www.trolltech.com.
