I have a very similar problem to this closed post: Image Scale Being Changed Upon Upload
The issue goes like this: I purchased an svg file. The file opens in GF as 18" x 10.4", exactly as the seller describes. If I open the same file in Inkscape, the dimensions are 13.5" x 7.8".
I wanted to make a slight adjustment to part of the file, so I opened it in inkscape, made the adjustment, and saved the file. The file then opened in GF at 13.5x7.8, exactly as it appeared in Inkscape.
Trying to manually scale up the adjusted file to “match” the 18x10.4 dimensions while in the GF app is not working well, no matter how close I zoom in, because it’s free hand (unless I’m missing some sort of snap-to somewhere). This is a 6-piece, layered project with each layer being a separate svg file. I only want to modify the 1 file. When I print the other 5 files onto my GF material, my one modified file is just ever so slightly off because I cannot get the exact scale by “hand stretching” it on the GF app.
All 6 unmodified files open in GF at 18x10.4, and in inkscape at 13.5x78 – an exact ratio match.
If I make my changes in Inkscape, and (still within inscape) scale up the entire image to 18x10, then it imports into GF at exactly 18x10, and prints out perfectly matched with the other sheets of wood. This “perfect match” is because of the precise measuring capabilities of Inkscape compared to the non-precise measuring capabilities of GF.
So… finally to the question: What causes the svg file to measure 13 inches in Inkscape and 18 inches in GF? And, is there a better way to achieve what I was finally able to achieve?
