---------------------------------
Summary: Scaling of Grayscale Windows BMP
Key: FOP-2849
URL: https://issues.apache.org/jira/browse/FOP-2849
Project: FOP
Issue Type: Bug
Components: image/unqualified
Affects Versions: 2.2
Environment: Linux
Reporter: Stefan Hegny
Attachments: big.bmp, big.fo
I'm using external-graphics with grayscale 8bit Windows BMP Files. Whenever the
Image has to be scaled down, in the pdf it is flipped horizontally, acutally
not keeping its aspect ratio, and the grayscales look dim. See big.fo.
Sometimes when using imagemagic convert (-depth 8 -colors 256 -type grayscale)
I also managed to get it flipped vertically and goes out of the block at the
top.
Extracting the image with pdfimages gives a ppm, its aspect rafio is correct
but still the colours are dim.
FO Files and sample BMPs are attached and here:

The small works ok, the big shows the described effect with FOP 2.2 - Im not
sure if the issue is FOP of the Java Image IO, please advise
Thanks & regards, Stefan
