Tilman Hausherr commented on PDFBOX-1954:
-----------------------------------------

I took a look at the PDFBOX-1870 file. The final image is really made of six 
triangles, and then a hexagone shape is drawn in the middle. The line of the 
hexagone is white, and its surface is black. So it is the white line that is 
too small.

Both the pre-regression version and the current version have an identity CTM. 

The difference between the two versions is that the java graphics has an scale 
of 1, while the current one has a scale of 4.16 (the number for 300dpi).
