---------------------------------------
Summary: Using new PDPixelMap() results in black image in PDF
Key: PDFBOX-2030
URL: https://issues.apache.org/jira/browse/PDFBOX-2030
Project: PDFBox
Issue Type: Bug
Components: Rendering
Affects Versions: 1.8.4
Reporter: Tilman Hausherr
Assignee: Tilman Hausherr
Fix For: 1.8.5
PDPixelMap.createImageStream() makes the assumption that BPC is 8. This is not
always correct, and it results in the weird effects described here:

I can confirm this by using GIF files. It happens both with bitonal and color
GIF files. I have fixed it by using some of my code from the trunk from
LosslessFactory.createFromImage(). That code is slower and longer, but is safer
because it avoids making assumptions about the low level data, as in the line
with "rgbImage.getData().getDataElements()".
I will also uncomment the "new PDPixelMap" segment in the ImageToPDF examples.
