Subject Re: Tiff image - color distortion
Date Tue, 28 Jan 2014 18:19:18 GMT
I had tried the following:
* Setting resolution to 96
* Trying out different values of scaling-method for fo:external-graphic

Configuration pages describe settings for tiff image renderer, but I assume
all those would NOT be used in my case, only pdf renderer...
