Summary: Implementation for ShadingType 1
Key: PDFBOX-1869
URL: https://issues.apache.org/jira/browse/PDFBOX-1869
Project: PDFBox
Issue Type: Sub-task
Affects Versions: 2.0.0
Reporter: Tilman Hausherr
Priority: Minor
Here's an implementation for function based shading and 4 sample files. The
implementation is rather simple. The real work is done in the function, see
subtask. I'm using a reverse transformation of the two matrices so that
getRaster() gets the "pure" values. The implementation works on two test images
and fails on two. I believe that the cause for the two it fails is the problem
I had with Type 4 and 5. I also noticed (when debugging) that for FUNSH01.pdf,
my implementation always gets the same matrices despite that its 4 different
areas in that page.
(Don't get confused by the name "asy-latticeshading.pdf", its not type 5
lattice shading)
