Unexpected results when applying plug-in filters

Post by XnTriq » Thu Jul 19, 2007 4:00 am

Some Adobe Photoshop compatible 8BF plug-in filters produce different outcome in conjunction with XnView as compared to other programs like Paint Shop Pro:
  1. Download the freebie plug-in collection (1.75 MB) from Flaming Pear's web site.
  2. Extract the following files from the ZIP archive to the folder where you keep your filters:
    • Swap Green and Blue-120.8bf
    • Swap Red and Blue-120.8bf
    • Swap Red and Green-120.8bf
  3. Open an image in XnView, apply one of the mentioned filter effects to it (they don't have any options to choose from) and save the result in a lossless format.
  4. Repeat the steps described in #3 on the same image with a program other than XnView.
  5. Compare the two results.
  6. Scratch your head.

Pierre, I've just downloaded and tested v1.91.2 (Jul 19 2007).
There's still some kind of problem:
The screenshot shows what I get when I apply Flaming Pear's “Swap Green/Blue” filter on this test.jpeg.Is the next release going to be version 1.91.2 or 1.92?

The number of incompatible plug-ins has shrunk considerably due to the release of XnView v1.92: no more issues with MediaSpark's Vignette Tranparent, VanDerLee's SnowScape or Flaming Pear's TransTone. 8) Earlier this week I updated the “Free Adobe Photoshop Plug-Ins” thread accordingly.

The filters that remain problematic when it comes to processing 32-bit images are some of Flaming Pear's Freebies, but also Etsuro Endo's Eliminate White and the internal Drop shadow effect.

Seems that some filters doens't like 32bits picture...
