Please, suggest me some libraries that will help me print PDF files that contain JBIG2 encoded images. PDFRenderer
, PDFBox
don't help me. These libs can print simple PDF, but not PDF containing JBIG2 images. PDFRenderer
tries to fix it (according to bug issue on PDFRedndrer's bug tracker), but some pages still (especially where barcodes exist) don't want to print.
P.S. I use javax.print
API within applet
Thanks!
UPDATE: also tried ICEPdf, is too don't want to work.
I came to the conclusion that all these libraries(PDFRenderer, ICEPdf, PDFBox) use JPedals
jbig2 decoder. Bug (some pages didn't print) come from this decoder library. The open source version of this decoder (which is used in PDFRenderer, ICEPdf, PDFBox) is no longer supported, but JPedal
has a new commercial branch of the project, and they wrote that the bug has been fixed in new commercial release, which costs $9k.
Any ideas?
UPDATE 2: yesterday I tried to replace JPedal's free library with other open-source jbig2-imageio
libraries. But yet I don't get any successful results, so I created a new topic on their project's page (google-code's forum - here ). Would be grateful for any help.
I also found some helpfull discussions on Apache PDFBox
bug-tracker: here and here.
As going through your comment in yms answer ie. " but what library I can use to extract images and (more importantly) put them back in PDF?"
Here is a simple demonstration of
1 ) Extracting jbig2
or you can say all images from pdf
.
2 ) Converting jbig2
image to any other format, in my case its jpeg
.
3 ) Creating new pdf
containing the jpeg
.
Using libraries jbig2-imageio and itext.
In the below example please change the resources and the directories path as per your need.
For this I had to go through several resources that I will attach in the end. Hope this helps.

There is a fork of the JPedal library by Borisvl located at
https://github.com/Borisvl/JBIG2-Image-Decoder#readme
which contains speed improvements and I believe it should also fix your bug.
EDIT : The bug is related to simple range checking. Basically you need to prevent GetPixel from accessing x,y values outside of the bitmap extents.
You need to make sure the following conditions are met before calling getPixel
col >= 0 and col < bitmap.width row >= 0 and row < bitmap.height
Here is some Delphi code with a couple of small range checks. I cannot test the Java code myself but you need to make changes to src/org/jpedal/jbig2/image/JBIG2Bitmap.java
procedure TJBIG2Bitmap.combine(bitmap: TJBIG2Bitmap; x, y: Integer; combOp: Int64);
...
...
var
begin
srcWidth := bitmap.width;
srcHeight := bitmap.height;
srcRow := 0;
srcCol := 0;
if (x < 0) then x := 0;
if (y < 0) then y := 0;
for row := y to Min(y + srcHeight - 1, Self.height - 1) do // <<<<<<<< HERE
begin
for col := x to x + srcWidth - 1 do
begin
srcPixel := bitmap.getPixel(srcCol, srcRow);

How about using AcrobatReader itself? It's a bit muddy getting it to work, and not a robust solution I guess. But will probably print all of it perfectly. And be free
