Patrick Corless added a comment - 20/Jun/17 1:09 PM Another design consideration will be the modification of how we handle and apply the image reference implementation. Individual implementations are currently applied globally to all image types. Unfortunately this approach doesn't work all that well. The blurred implementation works well for large rectangular images but works poorly for thin printer band images. The smoothScalled image type works a lot better for printer band images and neither reference works well for a large colour image. The new implementation needs to balance image type matching, configuration and performance considerations. For a example an 8K image should first be sample to manage the memory footprint of decoding such a large image. the color model should be looked at and the compression type to see if a image reference type may improve the image quality. And finally what is the current zoom and clip of the PDF view, can we make any further memory quality improvements. .
