At that point, I have opened the png I got from LibreCAD as a layer over my page template. Not quite the correct size to fit between the margins so I use the scale tool to make it a better fit. Not the sort of scaling you have to do, 9000 pix > down to 900 pix more like 2100 pix down to 2000 pix Not much in the way of reduction in quality.
The other thing to note, right at the end, The template was set up @ 300 ppi so anything I put in that template takes that value. (obviously).
Quote:I have 300+ images and although applying your procedure obviously is great, it will take me very long and cause to make mistakes.
Please, what is so difficult with setting that image size. LibreCAD (same as other vector applications Inkscape / CorelDraw typically use 90 or 96 ppi) Only the image size in pixels matters in Gimp.
However. Do not worry. It happens all the time, especially with book authors, but usually the other way round.
Open Gimp, make a page 8" x 10" but never check the ppi and get a default 96 ( or 72) ppi . Make their project and then find it is dreadful quality because everything has to be scaled up x3. You are the reverse big images to scale down to fit.
Quote:Can I just do this: Export with 96 dpi from Librecad and just open that image in gimp and go to print size and adjust dpi in gimp and that's it?
No, not in this case. That is a setting that the printer uses.
In Gimp you need the image the correct pixel size to fit your page template. I hope your page template is set up at 300 ppi and not 96 ppi. The size should be round about 2400 pix (8") x 3000 (10") for your project. You need your LibreCAD exports about that size.
Since you have already converted your 300+ LibreCAD drawings without changing the jpeg output image size in the LibreCAD export you are now stuck with a lot of drawings that you will have to scale down to fit your page template. Not going to be wonderful quality.
