Hi,
Yes I do get some data which does not equal -1. I used the following:
BufferedImage img = renderer.getPageImage(0);
for (int i = 0;i < img.getRaster().getDataBuffer().getSize();i++) {
if (img.getRaster().getDataBuffer().getElem(i) != -1) {
System.out.println(img.getRaster().getDataBuffer().getElem(i));
}
}
and got the following output:
-16777216
...
-14935012
-789517
-2368549
-16777216
-4605511
...
-11711155
-16053493
-14540254
-4737097
-16777216
-16777216
We do have a bug open which
occurs on MacOS, although it might also occur on other systems which results in
blank pages being sent to the printer. It is
still open at this stage and can be found here:
https://issues.apache.org/bugzilla/show_bug.cgi?id=53249.
Could you tell us the version of FOP you are running and the operating system?
Regards,
Robert Meyer
