Hi,
When the attached PDF page is converted to an image, the colors in the image are very different from the original. We tried both methods shown in your sample code (here).

The difference is clear when comparing the Aspose image output to the actual PDF:
Aspose: http://support.decos.nl/berend/aspose-image.png
Actual PDF: http://support.decos.nl/berend/actual-pdf.png
I have worked with the data shared by you and have been able to reproduce the issue in our environment. A ticket with ID PDFNET-43808 has been logged in our issue management system for further investigation and resolution. The issue ID has been linked with this thread so that you will receive notification as soon as the issue is resolved.
We are sorry for the inconvenience.
The issues you have found earlier (filed as PDFNET-43808) have been fixed in Aspose.PDF for .NET 25.5.
