second image file is decoded as black/white

Post by Guest »

Hello,

with the new version 1.74 I've got a strange problem.
When I'm loading an image and then go to the next file (e.g. with PageDown) then the second image (when it's a jpg, gif or png) is decoded as black/white (1 Bit) and you will see a white rectangle with some black spots on it (also the resolution is wrong). When you go to the 3rd ("Keep current image in cache" disabled) or 4th ("Keep current image in cache" enabled) image and then go back to the 2nd, then it's correct decoded.

System:
Windows 98SE
Athlon 1GHz
512 MB RAM

Best wishes.

Jan

I can't reproduce the problem. You view the first file (RGB), and you go to the next (black&white 1bit), there is problem?
Which fit option do you have?
Do you have enabled Options/View/High zoom quality?

Sorry for the confusion, I choosed the wrong title for this problem.
The second file, not depending of the type, is always displayed scrambled.

I did a screenshot, where you can see the problem.

It doesn't matter, if High zoom quality is enabled or not. Here is a screenshot from a scrambled picture in high quality mode.

The problem is also independent of the used fit option.

Hope this helps you.

Best wishes.

Wow, I've never seen a place with a countdown timer for images.

Oh yeah, I'll give them three e-mail addresses.... 8)

Very strange. This problem occurs only with 1.74?
Could you send me a sample, please?

Yes, the problem occurs only with 1.74.

What kind of sample do you like do you have? An image file?

Greetings.

The problem occurs with every file, also with the image below.

I've saved your image in a folder and copied it several times. Could not reproduce the problem. But I'm on XP, so probably no wonder.

- Does this problem occur with image files of any type (GIF, ...)?
- Does the problem still occur after renaming the 'PlugIns' dir?
- What's the size of free memory during such an XnView session?

Yes.

Dozens of MByte.

No! If the 'PlugIns' folder is renamed or does not exist, then the problem, does not occur!

I've renamed sequentially every single file in the 'PlugIns' folder, and the offender is located:
CADImage.dll

Cause I 've got no CAD-files, I leave this DLL renamed.

Thank you very much for the tip.

Best wishes.

Very strange, CAD plugin read only .dxf/.hpgl/.dwg
