Right, I forgot to mention that High quality zoom is always turned off for both Reduce and Enlarge in my XnView installation.Drahken wrote:It appears in your sample That xnview is applying some sort of antialiasing that psp9 isn't. Are you using a resample/high quality zoom filter in xnview but just plain zoom in psp9?
Code: Select all
Zoom / Rescaling Quality [ · · · · · · · · · · · · · · ●] Faster Better
I had it set to its maximum, but to my surprise I couldn't spot any difference between “fastest” and “best” (even post-restart).Paint Shop Pro 9 User Guide wrote:Adjust the Zoom / Rescaling Quality slider to set whether the Zoom tool quality is faster or better.
Faster will zoom images faster, but will display less fine detail. Better will zoom images more slowly, but display more fine detail.
<-- EDIT -- //Drahken wrote:EDIT: I just tried the image in psp7 and in xnview. Psp7 and xnview (with high quality zoom disabled) display it the same as you xnview example. Xnview with high quality zoom enabled displays it as very soft and almost smeared. I am unable to recreate the result you got in photoshop & psp9.

Each box has different methods for decompressing the data. On top of that, you have different reconstructive techniques like deblocking and deringing that would affect quality in varying ways. Those techniques also aren't part of the standard, so the visual quality can vary great from one decoder to the next.SCSIRAID wrote:Another likely contributor would be the MPEG decoder.

This decompression technique is based on more accurate dequantization of JPEG DCT coefficients and unlike most other JPEG reconstruction methods is not achieved by simply smoothing of a decompressed bitmap.
Note: Reconstruction will have no effect on unchanged blocks in a final image, however it can be used to increase quality and reduce degradation in blocks that are to be re-compressed, and in operations leading to full re-compression.
