              This appears to be fixed as the result of the image consolidation work done for PDF-322 around consolidation of imaging algorithms.

              The imaging pipeline for ICEpdf was reworked to use a pure JAI approach for loading images. In previous versions we had a dependency on the older now deprecated JpegCodec class which was removed in JDK 1.8. During this work quite a bit of common code was consolidate and refactored creating a new package for Raster operations.

              During our tests on Linux and Windows the image question loaded correctly regardless of the system property "org.icepdf.core.ccittfax.jai".

              I have to get some exact memory numbers but by introducing an inline image cache I can reduce the total number of images on the first page 32,581 inline images down to a combined cache that has only 3,593 elements.

              Updated the ScaledImageReference to create a generally RGBA or RGB image instead of trying to reuse the color model. This avoid the incompatibility issue the the image is now property rendered during the scale copy.
