            Description

            I try to migrate our project from ICEpdf-pro 4.3.4 to 6.1.0. I faced with capture document pages quality issue. Picture which was captured by v.6.1.0, has worse quality than it is for v.4.3.4. The both pictures have 100% zoom.

            If it is possible could you please give me some recommendations to fix it locally.

              ICEpdf 5 and higher eater no longer scales images by default. You can read up a little about this on http://www.icesoft.org/wiki/display/PDF/Imaging+Options . I would recommend you use the property -Dorg.icepdf.core.imageReference=smoothScaled to get a similar result to what you saw in 4.x

              Patrick, if I understand it properly I should set the properties like org.icepdf.core.imageReference globally for whole library. Is it possible to manage the properties for each document separately?
              (e.g. I need to process some PDF documents concurrently and change pictures quality depends on zoom)

              That's correct, the system property will change the the behavior of the ImageReferenceFactory for the whole library. The ImageRefernceFactory is unfortunately a singleton, so you could change the type returned manually but not concurrently.

              I see. So, are you planning to implement this managing properties possibility in the future?

              Possibly, we haven't had a lot of push for this but we could keep it factory but have an instance for each document.
