Mark Gibson updated FOP-3108:
------------------------------
Description:
Using PDF-Images to inject a PDF as an image (fo:external-graphic). Image/PDF
has a gradient fill component. When scaling the image, the gradient does not
display properly. Resulting from shifted gradient to no gradient depending on
scale.
*width scaling* All issues are found when scaling width by %
*height scaling* Doesn't seem to even scale the image
Files attached for testing:
* *{{pdf-external-graphic-scaling-with-gradients.fo}}* - the FO file, with a
selection of image inclusions at different scales and scaling methods
* *{{img-with-gradient.pdf}}* - the PDF image being injected in to rendered
pdf, containing a gradient filled component.
* *{{out1.pdf}}* - the result of running fop on above
Tested on Windows using FOP 2.7 and 2.8
Command used to execute is
{{fop.bat -fo pdf-external-graphic-scaling-with-gradients.fo -pdf out1.pdf}}
