Topic on Talk:How to save and upload sprites

So I'm trying to convert the Webp Files from the compressed version to the regular PNG and I get this error.

I think a more detailed example of what to put into the command line would be helpful

bitstream error probably means you are trying to decompress already decompressed file or something like that. like in theoretical situation if your input_file and output_file are the same it will override old with new one and next time you try on it will be this error. put output files in some folder maybe like: D:/webp_folder/bin/dwebp.exe d:/AE/original_file.png -o d:/AE/Converted/output_file.png

Hmmm, that didn't seem to work. If it helps I'm trying to decompress the steam files.

The Codeline I'm trying to use is the same though.

libwebp-1.3.2-windows-x64\libwebp-1.3.2-windows-x64\bin\dwebp.exe C:\Users\myname\OneDrive\Desktop\Datamine\0dc3e6d233bd5f61c3c77b9de407edd4.png -o C:\Users\myname\OneDrive\Desktop\Datamine\0dc3e6d233bd5f61c3c77b9de407edd4.png

I also tried replacing the second instance with a new location but that didn't work either

steam files were always encrypted, you cant open them even to look at them. Need to break wfs decryption first and this need real expert datamining, not what we do. Category of difficulty is same as trying to look into masterfile.enc for drop rates...

Webp isn't encryption its just modern compression method of images for web, same category of things as jpeg compression but lossless. In the first place you can open compressed webp like images with usual image apps and even wiki can open them, as example:

• 

  211000000 ui.webp

BUT: wiki cant work with mismatched file extensions (wrong Mime type error). So we either have to rename files to .webp like above and remake templates to use webp extention, or decompress .png (webp) into normal .png with this tool we are discussing. Its basically just a image converter. And encrypted file from steam isn't an openable image.

• Steam files are encrypted
• Mobile are not, and just need root for access into /Data (or using emulator with root)

Which is why only mobile files and paths are mentioned as source of game files on page, and steam files are not.

Ah I see. Guess I need to figure out how to get those images from mobile then.

also btw. When you will have files, just for wiki character/weapon/whatever pages you can use anything to just resave .png file into .png file, like even windows Paint 3d "save as" option is fine. Don't need webp tool.

Its specifically to open spines in spineviewer app and for spineviewer to not crash, only fully correct image conversion works. And original webp tool is one of those correct methods, other apps may work or not, need to confirm yourself for each.

It might also be helpfully to post recommended Emulators for datamining. Since I tried with Bluestacks but that didn't work.
