Brilliant! I ran it on my Mac using CrossOver. Perfect porting. NO flaws. A bit laggy, but that may be because my MacBook Pro is a few years old and I'm running a LOT of processor-heavy apps at once. Thanks!

Unfortunately I cant get the bulk feature to work right. it does only a fraction of the files I request. They are all in powers of 2 512x512 or 1024x1024


EDIT: I think something goes wrong when you have 1024x1024 pics or too many of them. This shouldnt be a problem for most people though. I resized to 512 and it worked fine.

So you think, when there are a lot of big pictures (1024x1024), some of them are not converted to blp, right? That's really strange. I tested mass (or batch, whatever) converter on 200 images, among them ~25 have resolution 1024x1024, and there was no problem, all files were converted. I'll make some tests again.

Thanks all for the feedback.

This seems to be the nicest thing for me, and my friend (It's great for him, because he knows NOTHING about pictue formats and batck conversions.)
Keep making this better, with more direct image editing features.

that's what i thought, i've been using button manager and blp lab for quite a while for small things like making screen-shot icons R > B colour channel change for icons, reducing quality of blp's to make em smaller in size, mass converting textures & icons, etc...

New version with major updates!

Now support saving in BLP2 format. Extended DDS, PNG, TGA formats. Provides information and format options for almost all supported image files (except bmp). Also fixed bug with mipmapping (when height > width).

Full changelog is located in first post.

This is a hugely efficient tool. Far better than ones I've used in the past (a combination of Model Editor and Image Extractor). Also find I can get better quality images that are smaller in size. Thank you for this.

I use blpLap and ButtonManager all the time and 2 sort of annoying things came to my mind:
  • The Zoom function is terribly slow and can crash the program when zoomed in too far. Also the navigation while zoomed in or decreased the window-size is crappy. You should add some sorft of way to move the picutre/the viewport with middlemouse, space or anything.
  • There should be a better function to see whether or not the textures actually make use of an alpha channel. If it's unused, all empty or whatnot there should probably be an information about that, similar to color count.

I'll do something about it. For now, you can disable "Use Lanczos for zooming" in the program settings.

Could you explain how it's supposed to be?

Appears to bug with "palette" mipmaps in that it generates 4*4 level 3 times instead of generating 4*4, 2*2 and 1*1 levels as expected. If this is an intended optimization (low mipmaps seldom used so can be discarded) then it should be a toggle-able option and it should also correctly specify the mipmap size (16, 4, 1) even if the address overlaps and still try to get the nearest colour.

Also seems to lack pure palette alpha support. BLP1 supports alpha without separate alpha channel, at least in the file description.

Given the age and work investment of the tool, open sourcing it would be nice. As it is BLP specification resources are lacking and if you found out something through reverse engineering or experimentation with BLP files it would be useful to the community as a whole if they could see the implementation.
