Well I can't really describe this with words so I'll just attach some pictures.

This is how it currently looks in XnView:

This is how its supposed to look:

Note: This only happens with some BLP's Also, some BLP's aren't even recognized by XnView and show up in the hex viewer
Any ideas?

Hi,

thanks for the software, it's an exceptional tool.

I've been having the same problem and am curious if there has been any update on this.

Currently impossible to reproduce for other people and me since we do not have the image files.

Move to "Confirmed".

I sent samples of trouble files to Pierre (xnview), and he confirmed them as received in this very thread. Do you need me to send them to another address?

Please visit: http://wow.curse-gaming.com/en/files/de ... converter/

There you will find the other tool that I'm using to view/convert BLP's, it includes source code in C++. I hope you find the information in it adequate.

Some information about the compression used in blp files can be found on http://www.wowwiki.com/BLP_Files and http://en.wikipedia.org/wiki/S3TC.

As far as i can see it's the files that use DXT1 compression. This format uses only 64 bits per block of 4 x 4 pixels, instead of 128 bits used by the DXT2 - 5 compression modes.

Hope this helps you to fix this bug, making this tool even better.

I am also intrested in resolving this issue, i tried several different tools for reading and converting blp files and none of them worked well , some not at all . and the result of xnview with doubled images with stripes and a messed up colour layout is not satisfying either ;)
