[Gimp-user] Size photo so it will consistently print at a specific size
Whenever I know I want to print a photo at a certain size, Ibring it into GIMP, and re-export it immediately, changing thename to photoXXX_8x10.jpeg. (So as not to accidentally killthe original file)I then do a rectangle select, and in the Tool Options section, click on Fixed -- Aspect Ratio, and enter 8:10 (for example) inthe box below. I then click 'n' drag in the image. The boxI make will be the right shape for the print (or I then go back andmake it 10x8, 'cause I got it in the wrong order...!).I release the left mouse button, and then use the side and corner buttons to enlarge the box, and click 'n' drag in the centerto drag the box around. Once the box contains all that I want toinclude in the photo, I press Enter to 'finalize' the selection (clickinside the selection to get the 'handles' back to further modify thesize/position).Once you have a finalized selection, the menu option Image->FitCanvas To Selection modifies the image dimensions to match the newsize/shape of the image. Export this, and you have something thatwill exactly match the shape of the paper on which you want to print. (Sometimes I don't want to crop ANY of the image, and then I just makeone of the dimensions LARGER than in the old image size, and just live with the fact that there will be white borders on two sides of the image.You may need to enlarge the canvas, and make a layer underneath your image, filled with white, to do this. You MIGHT choose,if your image is bordered with black, to fill this layer with black instead.) Note that here we are not concerned with the exact dimensions of the print,merely the shape (aspect ratio) of the image, as the printing firm (my cornerdrugstore's photo kiosk) is only concerned with matching the shape of theimage with the shape of the paper. ___ 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] Help newbie with plugin dev guidance
On 6/26/19 4:57 PM, MakerMatrix wrote: I've experience writing code in Perl, C, on UNIX platforms. But new to GTK, gimp plugins, python, and just about anything dev-related on Windows. I want to write a plugin/app that does the following: - Opens a GTK dialog that displays an MxN matrix of int values and a few buttons to interact with those values. Not much experience with GTK bit when I tried (PyGTK) it wasn't that hard. - Reads data over serial from an Arduino sensor to populate that matrix with measured values. Not a problem. - Once fully populated, allow the user to send the MxN matrix to a GIMP plugin that processes it into an M*S x N*S (where S > 1) 8-bit grayscale image You are already in the plugin. that can then be saved in a format that GIMP probably doesn't already support (that I don't yet fully understand but do have access to code that reads/writes it). Gimp supports most usual image formats. Is someone reinventing the wheel? You can add file type handlers in Gimp, and in the worst case the handler can save the image in a usual format and then run a converter on the file. - Run on Win/Mac/Linux if possible That will be Python, then, if you want to avoid recompiling things for all platforms. If you can please point me to resources/tutorials for learning how to do something like that, I would be grateful. I've already watched 2-3 YT videos on plugin development with script-fu and am about to go check out the tutorials link that I saw when I registered on the site. The Gimp source code contains several Python plugins. The python interface is documented here: http://www.gimp.org/docs/python/index.html Welcome to the club :) ___ 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

[Gimp-user] Size photo so it will consistently print at a specific size
Hi there! My friend and I are avid, rabid photographers. ;-) He is -far- more advanced than I in using GIMP (GIMP 2.10.10 ~~ on Windows 10 machines) to edit photos while I'm just learning. But independently we have a "problem" we can't seem to resolve -- so I am VERY MUCH hoping You have the answer! We want to size / save an edited photo so it specifically will fit (without any further editing, cropping, or other manipulations) a frame size -- ie, so we can save it as what would print as an 8-1/2 x 10 ...or as a 7-1/2 x 11-1/2 inch size. Now, I'll copy his explanation -- and hope Hope HOPE you can please help us??? Thank you SOOO Much!!! His description of our problem: " I need to be able to crop my photo with specific dimensions, ( 8x10 etc) export it to thumb drive for photo store to print and frame. When I use rectangle tool it’s a perfect square (wrong dimension).Once it’s a square and I change to 8x10 it becomes a distorted photograph. I’m familiar with the image scale process but the tool box on side of program confuses me. The fix ratio etc. Why are there two places to change size? The Scale plus the tool box ratio side? I’m missing a step or doing wrong sequence. I make sure I use inches and also at least 300 DPI..When the photo store corrects to fit a frame much of photo is lost including my signature at times. They all use PhotoShop or Lightroom and unfamiliar with Gimp program. My photos are fine but I can’t crop and scale to standard frame sizes for the print store. I found no Utube tutorials for step by step to follow. " I am totally baffled trying to save an image to specific size for printing at a photo store. My imported photos into Gimp are 6000 x 4000 from camera (not raw). I click on the rectangle tool which opens tools for ratios, fixed etc on right side column of Gimp program. I change the pix numbers to inches such as 8.00 x 10.00 and hit fixed. The ratio I believe is at 1:1. Then I go into scale and again change to inches and type the 8x10 again. After which I export as .jpg. The two sizes I am most interested in are: 7.5 x 11.5 and the 8:00 x 10:00's. Watch all sorts of Gimp tutorials and found nothing that help with step by step guide. In addition to this problem when I crop an image it's sizes are uncommon for framing.. If anyone can guide me through this I would deeply appreciate it." I SO VERY MUCH HOPE YOU CAN HELP!!! Thank you!!! ps...the saved image is simply because a file is required to be able to post this question---it is not 'the' photo driving us nuts, just a thing to be able to post our question; again, thanks!!

Re: [Gimp-user] C2G
Hey, I saw something similar... this one is about alpha channel, and .dds export, a guy is showing : https://imgur.com/a/qW7zzdE from the forum message : http://www.maniapark.com/forum/viewtopic.php?p=211743#p211743 And I've tested to go back to Gimp 2.8 as said on his message, it's ok May be it's the same problem for you ?
