JPEG-LS encoded color images with interleave mode = none are not displayed correctly

Post by vbaderks »

The JPEG-LS standard provides 3 options to encode color (multi-component) images:

interleave mode = none
interleave mode = line
interleave mode = sample

XnView 2.49.2 can display "line" and "sample" correctly, but "none" is displayed as 9 small images:
(see attachment).

by line is displayed correctly as:
screenshot-good.png
Note: irfanview has the same problem, the Accusoft PICTools Apollo demo viewer shows both images correctly.

The source .JLS files are attached.
