Hi, what do you have in mind exactly? You mean images without headers
or the images from digital cameras?

I meant images from digital cameras. That would be really great. I would actually only need to open them, it does not have much sence to save them, does it?

Thank you, Dave

The problem is there is no single RAW format, there's like dozens of them, usually every camera manufacturer uses his own RAW format.
Some also use encryption. Any specific RAW type you are interested in?

Ah, I didn't know. My graphic editor supports opening of something called "Raw format" (ext. RAW) but I don't know what the format really is and I haven't tried if it supports the files generated by my camera. Anyway I would appreciate to be able to open raw formats of basically any camera using vampyre but if there are many formats it doesn't have sence to implement all of them.  :'(

Anyway, thank you for your answer!

By the way, do the formats also differ among products of one producer? If not maybe it would be sufficient to support Nikon and Canon. Who buys the others??   ::)

Raw with *.raw filename is usually just pixels without any header, not the image from camera.
I'll look into Nikon and Canon raws but I'm afraid these two are protected somehow.

Looks like it can only be done with plugins from the vendor (Nikon, Canon, etc.). But for next release (after 0.26.4) I plan to create image loader that uses WIC (http://en.wikipedia.org/wiki/Windows_Imaging_Component). There are plugins for WIC from most camera makers.

so instead of support many RAW formats, it will be very nice to support DNG format.

without WIC requirements.

Looks like DNG is TIFF based and recent LibTIFF versions support DNG-related TIFF tags, so it might be easy to support this format. I'll test it later.

But you'll need some external matadata parser. Next Imaging version will be able to read raw metadata in XMP, Exif, and IPTC formats, but something else will have to parse it.
