which palette generation method are you using? octrees or median cut? or do you use a premade palette? It would be nice to know, since I feel the color quality is a bit lacking.

Octree, of course, median cut method generates quite inaccurate images.
I wrote above, there's an option "Error diffusion", which enables Floyd-Steinberg dithering for image during palette generation process. As far as I know, BLPaletter applies dithering by default.

well median cut is better in some specific cases (high amount of highlights). However, octrees are almost always better.

thanks for telling, keep up the nice work ;).

Attached BLP is valid in game and in WC3Viewer, but not in your tool. Generated with PitzerMike's TextSplat font generation tool.

Also, awesome tool, other than this bug.

The problem is in that the size, specified in BLP header (1024), doesn't match with real image size (2048). Thanks for reporting, it will be fixed in the next version.

New version

My attempts at using the Mass Converter have been fruitless. Either it only converts one or two in a directory, or pops the error "Nothing to convert".

Spec · 02-05-2010, 04:36 AM

That's quite untypical. How about screenshot of the corresponding folder and the Mass Converter window?

Archmage Owenalacaster · 02-05-2010, 06:22 AM

I know it's not an issue of file format, since doing each one manually seems to work. I examined each and every file and their formats were uniform.

Note that I've redacted certain parts of the directory only because My Lady has her name as her user profile on this computer.

Spec · 02-05-2010, 03:20 PM

Caught the problem. The extensions of some files are written in UPPER case. Extension is not transformed to lower case in mass converter handler. Thanks, fixed now.

New version coming soon.

can you add something for generating images out of files (you know, the transparent 1px border thingy)?

New version

Major features of this version are comments in BLP, the BLP optimization and partial DDS support.

Earth-Fury · 03-06-2010, 07:35 AM

Can you add an option to the mass converter to maintain the directory structure of the source directory?

so:
source\blah\a.blp
goes in to:
dest\blah\a.blp
instead of:
dest\a.blp

-----------

On a somewhat unrelated note, this tool converts (almost) every texture in WC3 insanely fast. Good job.

I recently got request on such feature from testers, so I'm going to add it in the next version.

Also, due to new resizing method implied in the library, I decided to compare compressed BLPs saved with v0.3.2 and v0.4.0, got following results (resaved BloodElf-SpellThief.blp texture):

Table:

Version	Method	File size (in bytes)	Size in MPQ (in bytes)
0.3.2	Baseline, 80%	85 608	84 763
0.4.0	Baseline, 80%	82 776	81 931
	Difference	2 832	2 832
0.3.2	Progressive, 80%	86 145	83 428
0.4.0	Progressive, 80%	83 495	80 792
	Difference	2 650	2 636

Not bad, at all.

It appears that some .blps generated appear broken in war3 Model Editor but don't in Blp Lab.

I think its something to do with palatted BLPs, but it could be something else. I attached the .blps which are "faulty"
