Tilman Hausherr commented on PDFBOX-5597:
-----------------------------------------
Hello [~itai], could you have a look whether SampledImageReader is at fault
here or the jbig2 decoder (this would be the file
"org\apache\pdfbox\jbig2\image\Bitmaps.java" in the jbig2 decoder)?
{code}
final int width = (int) Math.ceil(clipped.getWidth() / subsampling);
final int height = (int) Math.ceil(clipped.getHeight() / subsampling);
{code}
[~lycheng] the second file makes no problem here, but IIRC you have your own
getSubsampling() to decide on a scale.
