I badly need to edit graphic file that unfortunately comes in some weird RAW format. The thing is that it seems that there's no freeware/open source software that could do such thing. Until now I've tried:

  • Paint.Net with DCRaw plugin - it doesn't open the file + error prompt
  • Gimp with UFRaw plugin - it doesn't open the file + error prompt
  • RawTherapee - it doesn't open the file and no error prompt
  • IrfanView - it DOES OPEN the file and it even seems to edit it, but saved file turns into "graphic gibberish"

The file is definitely not broken, since IrfanView opens it.

Question is - is there any free software that can edit RAW files?

  • IrfanView probably opens the embedded preview. Can you chek the image dimensions obtained this way?

  • What is a RAW file? As far as I understand, it's a generic name for ... values? Pixels? RGB, per line or channel separated? Does it have a width and height? And so on. Perhaps that's why there is no "universal" editor.

  • @Rad RAW is an image format usually from cameras that contains a lot of unprocessed sensor data.

    If it were me, I would simply ask the provider of the image to resend a tif or jpg. If they're sending out raw files, they probably don't completely understand how to send images.

    Would you post the first few lines of a hex dump of the "weird format" file? e.g., the result of "od -c file.raw | head -4" or "xxd file.raw | head -4" Aug 31, 2016 at 13:11

Are you able to simply covert the files and then use them in Photoshop? I've used this here app to convert .raw files to .jpegs: https://raw.pics.io/ (I think I had to pay a few bucks and it was a bit of a clumsy app but it did the trick :)
