            Description

            The PDF in question contains a external graphic state dictionary with he following value <</ca 100>>. The problem here is that a /ca value should be defined in range of 0->1.0. We have code that takes the 100 value and divides by 255 which is a common process for colour values.

            When the division happens we get a 0.39 transparency and the rendering of the graphics looks light. I think its safe to say the division/conversion code should be used for /ca and /CA values.

            This looks like an issue with the iPaper.Net encoder but I think we can fix this without to many regressions.
