Volker Bier commented on PDFBOX-2141:
-------------------------------------
Okay, i made the printouts:
# the file from PDFBOX-485 is unchanged
# pslib-shading.pdf does show text with a gradient in the new version (text is
missing in the old version)
# 000004_ShadingPatternTextPDF.pdf does now show text with a gradient in the
new version (text is unicolored in the old version)
Both pslib... and 0000.. show the additional line on the HP1320, but that is
also the case with the 1.8.6. version.
I can not update firmware as this is a company printer, and I am not sure with
the driver as I use this as a network printer on my linux machine.

> The attached PDF draws a text filled with horizontal shading going from red
> to blue. When rendered via PDFBox, the text is completely filled with red.
> The problem is that AxialShadingContext#getRaster() gets called with
> positions that completely fell outside of the range stored in its coords[]
> field. The fix seems to be to set glyph transform rather than graphics2d
> transform in PageDrawer#writeText() as shown in the attached patch.
