Description
We have had quite a few requests to improve the render quality of DeviceGray images. This requests usually falls into two different types; fax scans and small images used in type 3 fonts. When this type of document is viewed at the default zoom level the image can be difficult to read and or looks jagged.
Turning on the following system properties helps a bit but the end result isn't as crisp as adobe.
-Dorg.icepdf.core.target.dither=VALUE_DITHER_ENABLE
-Dorg.icepdf.core.screen.render=VALUE_RENDER_QUALITY
-Dorg.icepdf.core.screen.interpolation=VALUE_INTERPOLATION_BICUBIC
-Dorg.icepdf.core.imageReference=smoothScaled
This bug will capture changes to the smoothScaled image reference implementation to help improve image render quality.
