I have been trying to convert a TIF file in Lab colorspace to PDF format, but the converted file has the colors changed.
When converting to PDF, I end up with a file like [Tiff-Lab-300DPI.tif_ImageConverter.pdf]..
Note: I also do a bit of resizing before converting to PDF.
Comments: Hello, I had a similar issue while loading jpg image with CMYK colourspace. When I used them for compositing with other picture (RVB) colours seemed inverted... The TIFF image is saved in the LAB colourspace here so I presume it's the same problem. Also I found this: http://www.imagemagick.org/Usage/resize/#resize_colorspace Apparently we need to convert colourspace to linear RGB (from any other colourspace including sRGB which is gamma corrected) BEFORE doing the reisze... can you confirm?
