Title: JPG from raw squeezed after tags transfer from SRW file
Post by: srwuser on June 28, 2018, 06:08:10 PM

I'm trying to extract JPG from raw SRW file, but after transfer of tags from SRW to JPG image is getting squeezed by X axis.
Here is a command I'm using:

Code Select

exiftool -if '$jpgfromraw' -b -jpgfromraw -w %d%f_%ue.jpg -execute -tagsfromfile @ -srcfile %d%f_%ue.jpg -overwrite_original -common_args --ext jpg .

Extracted JPG (result of jpgfromraw, without tagsfromfile) looks fine and became weirdly squeezed only after tags transfer.
That's probably a problem with orientation because another photo in portrait orientation looks ok.
ExifTool version is 11.03, OS is macOS High Sierra

Can't attach images, so I've uploaded them to dropbox:

and yeah, JPG looks squeezed only in some programs, e.g. XnViewMP

I can't look right now, but the only things I can think of that could potentially distort the image like that are the EXIF Orientation and XResolution/YResolution.

Yeah, the resolution tags in the raw are really odd

Code Select

All RAW files from my Samsung NX500 camera have the same weird resolution in inches. :(
Are there any possible workaround? Like "transfer all tags except orientation"?

I'd suggest not copying the X/YResolution tags. Add --XResolution --YResolution after the -TagsFromFile option. Note the double minus signs.
