Tilman Hausherr commented on PDFBOX-958:
----------------------------------------

Is there anybody who can access the PDF of this issue, and if yes, what URL=
 works? I get an error. I suspect it has something to do with url-encoding =
of the "(R)".

> Of the PDFs we've tried running through PDFBox and generating page images=
, a number of them (coming from disparate sources and method of creation) s=
eem to produce images where an image that was embedded in the page of the P=
DF shows somewhat mangled. It seems to be divided by horizontal stripes, wh=
ere some stripes look normal, others seem to have some kind of "smearing" e=
ffect going on. See attached images and original PDF (image is of page 13).
> I marked this as critical as we are trying to use PDFBox in a project whe=
re page images are crucial, and inability to produce reasonable looking pag=
e images is pretty much a deal breaker.=20
> The code we use to extract the images looks more or less like the followi=
ng:
> =09=09=09=09=09BufferedImage image =3D page.convertToImage();
> =09=09=09=09=09
> =09=09=09=09=09SmartDeferredFileOutputStream outStream =3D new SmartDefer=
redFileOutputStream();
> =09=09=09=09=09String[] writerFormatNames =3D ImageIO.getWriterFormatName=
s();
> =09=09=09=09=09ImageIO.write(image, "jpeg", outStream);
> =09=09=09=09=09outStream.close()
> We've also tried specifying "png". In both "jpg" and "png" cases we get a=
n image file that is indeed the correct format, and both images look exactl=
y the same.=20
