Hello,
So I guess my question is: What should Ri be?
Given unsigned image width, rows per strip, and samples per pixel (1 or 3), and unknown unsigned variable Ri (JPEGRestartInterval):
if(width%8 != 0 ) {
Ri=(width+(8-(width%8)))*rowsperstrip/64;
} else {
Ri=width*rowsperstrip/64;
}
if(samplesperpixel==3){
if(Ri & 0x01) { Ri++; }
Ri=Ri/2;
}
This handles so far the images I am testing. So, if you come across some TIFF/J that it does not handle, then that is another case, and please say so.
Andy
