I'm not sure what the official way to solve this is, but when I am putting several imagestogether, I look at each in an image viewer to see what the width and height are in pixels, add those figures together as is appropriate to how the images will be placed in the final image (if I am not sure, I just make it bigger than I think I will need - I can always crop it down later), and then open GIMP.I immediately do a File->New> and set the width and height to the figures I calculated,and under Advanced Options set the initial content to Fill With whatever color you want.I usually pick white, but you could use the fore- or background color, or transparency.(You may wish to set the x- and y- resolution, but I don't know if it is really necessary - mine is set to 300 ppi, but I don't know if that is default, or because I set it some time...) Now that I have a background layer that is (at least) large enough, I then File->Open as Layersall of the images that will be used to make the final image (remember, you can save time byCtrl-Clicking multiple individual files in the same directory, and shift-clicking the first and lastfile of multiple files that are located right next to each other in the same directory). Now, just move things around as you like, and/or cut/paste parts of one layer onto otherlayers, etc. Sometimes, when I know that I only want a little from each image, I will just cut/paste bitsof each layer onto the background, and play around with exact placement there, later... - When I go on a trip, I will often use this technique to open pages of a downloaded .pdffile of a complete bus schedule, knowing that I only need a few lines on a few pages.I'll cut and paste those lines, and probably the page headings, on what will end up asonly one printed page, which I can then take with me. ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
Re: [Gimp-user] Stitching Photos
Did you name the pasted layer? If not, the layer will appear as Floating Selection (Pasted Layer). Double click on the pasted layer’s name and give it any other name. Move the newly named layer to its new position - ~50% layer opacity can help with this. Under the Image menu, click on Fit Canvas to Layers. That should give you the canvas size you need and you should be able to see all of your pasted layer. Don’t forget to change layer opacity back to 100%, or whatever your project calls for. Hope this helps.

[Gimp-user] Stitching Photos
I can't seem to make this work; I don't see any option for enlarging the workspace. I can enlarge the canvas as much as I want, but this doesn't change the size of the "window" through which my content is visible. As I paste in the second image and slide it over--in this case to the right, it disappears. It's almost like the second image is sliding under the blank background that was created when I enlarged the canvas. >There are automated tools to facilitate this, but I have not used >them. > >The manual process is not terribly complicated. > >First, open one of the photos in the GIMP, then import the second >photo >as a layer.

Best ask on https://discuss.pixls.us/ As I said, the profile is loaded in Windows 7 for correcting the monitor. And yes, it affects the output significantly. So, I afraid of double correction, because the exact mechanism is not explained in terms of source1, source2->operation->output. -- AndyJP (via www.gimpusers.com/forums) ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list

Does having the monitor profile on/off in either of Gimp / MS system affect the way out-of-gamut colors are shown? Otherwise, if there is no difference I would keep the monitor icm enabled in Gimp (just on the basic of no-visible-difference). Want a better answer?
