Looking at your other posts to get the context, you are running into PDF issues. 600 ppi is a suitable value for printing an image of a postage stamp but not for a poster. Probably 200 ppi is more suitable.
However, I used 300 ppi in the video demo, I would not go above that.
The procedure is
Make a new empty canvas at the required size and ppi
Drop your image into it (or copy/paste if you want)
Scale that to fit
Export as a PDF
...and that gets you a large PDF
For a smaller PDF file size use ImageMagick http://www.imagemagick.org and a command
Code:
magick infile.jpg outfile.pdf
about 5 minutes https://youtu.be/TysvSEfd-is there might be something in there that helps.
I really appreciate the effort you went to - making and uploading a video.
Is there any downside to using 600 dpi? This is a reproduction of a painting a relative did so I'm looking to squeeze every bit of resolution possible under the circumstances. I'm conscious that I'm going to lose a certain amount of resolution just due to the limitations of the printer.
Also, if I export from the xcf file to jpg first as an intermediate step it means I'm making the pdf off the slightly less sharp jpg which defeats the purpose of retaining as much quality as possible. When I compare the 600 dpi jpg vs the forced 600 dpi pdf both made from the 600 dpi xcf file I do see a small difference in the fine details - it's not profound but it's discernible. At that point it seems I might as well have them print the jpg file, or is there still an advantage to using pdf?
