BLPNG Converter  Popular! (More than 5000 hits)

Version: 2.5.3
by: Digital_Utopia [More]

Introduction

While doing various WoW related projects, I was always in need of a utility that would convert BLP images to a more common format. Unfortunately, all the converters I came across would fail on at least one BLP format. Since I recently created a 3ds Max BLP import plugin, I decided to use the knowledge I gained of the format, to make my own converter. This is that converter.

I've used this personally for a few months - converting maps, UI graphics, textures, etc, and have yet to find a BLP file that it not only cannot convert, but cannot convert correctly.

About

BLPNG Converter (Pronounced "Bleeping Converter") Has gotten a bit of a makeover for it's second version. In order to keep things as simple and uncomplicated for the user as possible,it's left it's meager Console life behind, and has been given an actual UI.

In addition, it can now convert from standard Windows image formats (BMP,GIF,JPG and PNG) to the BLP format as well!

Use is still nearly as simple as before - although now you will have to actually open the app first. Once it's open, drop any number of files or folders on the appropriate square, and it will dutifully convert all the appropriate files within, to the desired format.

The addition of the UI has also brought some additional options with it. You can now choose files or a folder from the appropriate menu choices, and set the desired BLP format details. In addition, you can also select to have BLP Converter save your settings between sessions - although, this does require it to leave a settings file, in a folder, in your AppData/Application Data folder.

Despite, and even considering this, it remains just as portable as the original version. Run it from wherever you'd like, and if you should choose to want to get rid of it, just dump it in your recycle bin and forget it.

Oh a few other things.

1) The UI will display a progress bar, count, percent complete, and the current file - while it's processing - but the fancy Taskbar progress bar also makes its return. So if you're doing a huge conversion job, and want to work on other things - feel free to minimize it or let it sit in the background. Well, as long as you have Windows 7+

2) Instead of the fancy Yellow progress bar on the Taskbar, if it's unable to convert some files, the "Conversion Complete" message that shows up at the end, will now have a yellow "caution" icon next to it, with a link to allow you to see what didn't get converted, and why.

3) More of a warning: The "Conversion Complete" message will show up at the end of any action, and the green checkmark only means that it didn't encounter any errors. There's currently no special status if it didn't find anything to convert - such as if you happen to drop a folder of png files, on the "To Png" square.

Requirements

Yep, I'm about to say that 'N' word...

.NET 4.0 is required.
aaaand...Visual C++ Redistributable

Which also means that this is, indeed, a Windows application...and this time written in Managed C++, instead of C#.

Despite the odd requirements, it has been tested, and does still work in Windows XP.

As far as you Mac people go - here you go.


Supported Formats

This is for reference, and completeness only. You're not expected to, or required to know this.

BLPNG Converter converts all known (to the author) varieties of the BLP format to PNG. This includes...

  • BLPs with and without minmaps
  • Indexed (256 color) BLPs with 0, 1, 4, and 8 bit alpha
  • DXT Compressed BLPs with 0, 1, 4, and 8 bit alpha, as well as handling both types of 8 bit alpha (DXT3 and DXT5)
  • Uncompressed BLPs with 0 or 8 bit alpha

Issues, Problems, Bugs, Questions, Etc...

I want to hear them all.

This should be perfectly functional - as the Conversion code has been lifted directly from the current Photoshop plugin, and polished to a sexy shine. But...stuff happens - so if you do run into an issue, please let me know and I'll correct it as soon as possible.

oh...and, uh- sorry for taking so ungodly long on this, jeffy162.


v2.5.3
  • Attempting to convert TGA files with flipped row order would silently fail. This has been corrected so it will now fail very loudly. No...wait. I'm being told this will now work correctly, but also silently.
v2.5.2
  • Further oddball Alpha Bit/Alpha Mod formats are supported - which don't appear to do anything except for screw with parsers.
  • TGA files with transparency would lose color information in areas that were fully transparent, resulting in those areas appearing black when converting to BLP - this has been fixed.
v2.5
  • BLPNG Converter is now a 64-bit application, because 2021.
  • BLP files with DXT compression, with an Alpha Bit format of 72, will now be successfully converted per the DXT5 compression it actually has.
v2.4
  • BLPNG Converter now supports the TGA format!
  • An "Output" menu has been added, to facilitate switching between PNG(default) and TGA output, for converting BLP Images.
v2.3
  • BLP files with non-lower case extension (i.e. .BLP as opposed to .blp) would silently fail when being converted to PNG. This has been fixed, and the author flogged, for such a stupid bug.
v2.2
  • Attempting to convert BLP files without mipmaps would result in a "Malformed BLP Data" error. These files should convert now.
  • Attempting to convert a single unsupported format to BLP, would ambiguously result in a green checkmark. Error list will now track any and all unsupported formats given to it. This will result in a yellow warning icon if converting a folder of images to BLP, and the folder contains other formats - but it will still convert supported formats normally.
v2.1
  • Wrong build source caused conversion to fail - this has been addressed
  • Higher DPI settings would cause all sorts of UI display issues, this has been fixed.
v2.0.1
  • Rebuild to address a Windows 8.1 compatibility issue, which would result in the application not starting
  • Fixed an issue where the DXT Compression option was not appearing as checked when selected

Any chance of getting this to convert the other way also?

I have no problems with that idea. I'll work on it, and release an update towards the end of the week.

This has come a long way. Truly this is exactly what I've been waiting for.

Going to be updating my Clean Icon packages today, we'll see how they're received.

57200 PNGs being converted!

O_o

Well, that should definitely put it through its paces! Please let me know if you run into any issues; but beyond that, thanks for showing that there is an actual demand to revisit this project.

I have a habit of letting things sit on the back burner too long - if I don't have a use for it, and nobody bugs me about it

I reuploaded my packages I had no issues at all, this has saved me an immense amount of time!

Btw, if you're any good with writing a simple batch file to move files / copy files I'd love to get some help from you.

Shouldn't be too much of a problem - send me a pm with what you want it to do, and I'll see what I can do later.

Did you ever get round to testing Xcode with this? Been looking for a blp to png (or tag) convertor who can actually convert BACK to blp. Seems to be a common issue

Error when attempting to run on 64-bit Windows 7:

"The program can't start because MSVCR100.dll is missing from your computer. Try reinstalling the program to fix this problem."

Google indicates this means the Visual C++ Redistributable is missing, but that is not the case for me (2005, 2008, and 2010 installed), nor am I missing the .NET Framework (1.1 and 4.5.1 installed). Windows Update reports no updates available. Are there some specific non-latest versions of these things I need?

Try these. I do know you said you tried it but give this link below a try. I know you are not stupid or anything so please do not feel as if I am Implying.

http://www.microsoft.com/en-us/downl....aspx?id=40784

You have to do both

vcredist_x64.exe
vcredist_x86.exe

This worked for me oddly enough. Please let me know.

Ugh, Microsoft's search function is about as useful as Curse's... it only brought up the 2010 package. I'll try that 2013 version. Thanks for the link.

edit:
Nope, same error after installing both x86 and x64 versions of the 2013 package. The file that is claimed to be missing -- msvcr100.dll -- is present in Windows/System32. Copying it to the same folder as BLPNG Converter.exe (as I've had to do with some other DLLs for other programs) did not help either.

Curious issue, that's for sure.

I'm not sure how much this will help, but it was compiled with Visual Studio 2012 - so maybe installing this:
http://www.microsoft.com/en-us/downl....aspx?id=30679

will fix the issue.

It's gonna be a while. Although I did manage to back up all of my Mac work, the hard drive it was installed on failed, and I currently don't have room for both Windows and Mac.

Not that it does much good, but, at the time, I was making decent progress with the UI. Hopefully before too long, I can get everything back up and running. Sorry about the delay!

I can't program that well, nor am I used to coding for Mac, but mind if I look at it? (Mac user -- needless to say?)
