Why does ACDsee display Jpegs like this?

[Jske]

Hi, I dunno if this is the right place to post this, but here goes...

I am having difficulthies with ACDsee Pro 2 when displaying Jpegs. It doesn't seem to decode them correctly or whatever it's called and I can't for the life of me figure out what's wrong

But as they say.. a picture is worth a thousand words, so I took a screen dump of a picture while using ACDsee and when using the standard Windows XP viewer for comparison.


XP viewer:

ACDsee Pro 2:

notice the piss poor quality of the ACDsee in comparison? I've tried to change the sampling settings in ACDsee, but that doesn't seem to do anything at all from what I can tell.

I don't want to just use another viewer as I use ACDsee for cataloging and keeping my database, plus I paid through the nose for it :)


(ACDsee support is useless as with 99% of all software support teams) They just said something like "Uhm duuh... it must be something with the registry.. try reinstalling" which has been tried to no avail...


Please help or direct me somewhere where they might be able to :)

Thanks in advance

Are you viewing the jpegs in ACDSee at 100% or zoomed to fill the screen?

It's hard to tell from your screenshots because there are so few colours, but it looks like there is some pixellation which could be due to the zoom method selected in the program's options. Are there any other options available to improve the zoom quality apart from the resampling settings?

Can you post another ACDSee screenshot of a full colour photo so we can see if there's any banding or problems with the colours.

on the older version that i use there are three (3) options

1: auto enlarge to fit window
2: auto shrink to fit window
3: show "real size"

viewing a low quality image at full screen will do
exactly what you showed

Thanks nego-oh-oh.

Like you, I've only used an older version (I prefer CompuPic Pro). Are there any options in ACDSee for image decoding. In CompuPic you can select the jpeg decoder to be smart, accurate, fast or extremely fast. You can also change the scaling quality, resizing quality and hicolor optimizations.

It doesn't matter at which level of zoom it is displayed, it's the same at 100% 50% 200% 33% and so on.

No, there is not really any where (that I know of) where you can configure the decoding
