Describe the solution you'd like

These RAW image formats are already loaded properly if the input is explicitly set to Raw or Dng, otherwise they are detected as TIFF or other formats and the load could fail:

• FFF (Hasselblad)
• MDC (Minolta)
• MOS (Leaf / Aptos)
• ORI (Olympus)
• RWL (Leica)
• SRW (Samsung)
• STI (Sinar CaptureShop)
  File samples can be be found online (they would be quite large to upload), e.g. on https://raw.pixls.us or https://www.rawsamples.ch/index.php/en looking for the manufacturer name.
  They are also supported by the Windows Photos app (except for MDC and STI) and other software using libraw.
  It would be nice if they were automatically recognized as raw images and were added to the MagickFormat enum so that the format and its properties can be checked at runtime.

Thanks for request this. The formats will become available in the next release. The only one that I did not add was ORI because I think that should be ORF and that is already supported?

[manfromarce]

Thank you for considering. .ORI is a different extension used by some cameras for the first frame and is produced along with ORF files, it's likely the same format as ImageMagick from command line and other software recognize it when it's renamed to .orf.

[dlemstra]

For the ORF format we can detect the image type from the header of the file. Do you think we should also add the .ORI format to make it more clear this is also supported?

[manfromarce]

You can avoid adding Ori explicitly if you don't want to, as I see it is automatically detected as ORF in Magick.NET and it's not very common.
