Tilman Hausherr updated PDFBOX-1442:
------------------------------------
Attachment: pdfbox-1442.pdf-1.png
I got this perfect rendering by using the initial CTM of the substream (as
mentioned by John in March 2014 in PDFBOX-1094). However many other shading
PDFs no longer worked, unless I took the local shading matrix when the initial
substream CTM was the identity matrix.
> bar chart converted from PDF is totally a black area.
