I’ve noticed the PdfConverter methods don’t retain the PDF document’s original page size. For example, when converting a PDF whose pages are 8.5x11" and written at 150dpi, the resulting image is 1275x1650 pixels regardless of the specified resolution: the default 96dpi resolution results in a 13.3x17.2" image while a specified 300dpi resolution results in an image that’s only 4.25x5.5".
We have fixed this problem. Please download hotfix 3.4.4.
