Seems like a basic function and run into it a lot but haven't found a tutorial yet. Basically, I want to make a ringed object thinner so it doesn't lose its size, just needs to be narrower. Is there a way to do this?
I am switching over to Gimp from another edit program and could use a little help. I take photographs of rescue dogs to post onto adoption websites, mostly for Labs4rescue. The main thing I do is to remove the leashes from the photo and do a little cropping. I can't figure out how to do that on this program. I can not access the user manual it says that something crashed and to restart my computer. That didn't help. In the previous program I used, I would put the cursor on an area that I wanted to copy and then use the brush to cover over the leash. This worked great. Can anyone teach me how to do this on Gimp?
I thank you and all of the dogs looking for forever homes thank you.
Hello all,
New to Gimp using 2.10.10. I have 25 photographs taken on my iPhone that I need to take and produce a set of files to be used on the web and then another set to be used for print on a home/office printer. I understand I may be saving 25 files two times but as for actually resizing the files, I'm at a loss. Appreciate any guidance whatsoever!
From now on, one can not use older versions of photoshop that one bought in the past !! So GIMP is now curtainly a good replacement for those with a small budget.
I do not remember whether this question was already discussed, hence I apologize in advance if so.
Assume an image has been "quantized" using mode indexed (then back to RGB).
The image shows -for example- areas of 8 different colors (if 8 was used while temporarily converting it to indexed).
But the number of separated color areas is often as expected greater than 8, because there are areas of the same color not contiguous, for example again we see 12 separated areas.
Interactively one may use the fuzzy select tool to work on each separated area, but from inside a script I don't see an easy way to do the same, because the gimp_image_select_color considers all together -as expected- the areas having the same colors, and the gimp_image_select_contiguous_color requires an x,y identifying a pixel position.
Is there a way to access separately each area without using a complex scan of pixels in the image to identify each of the 12 separated areas?
Many thanks.
Hello Everyone: I would like to be able to design/create decorative lines, such as would be used in a document to separate content or underline a heading. See attached examples. Does any know of a technique or tutorial or plugin that would accomplish this sort of thing in GIMP?
I was wondering if it is possible to create a reference grid. I have a couple of photos...different sizes...and would like to render a grid every 1cm. I managed to do that with Render-Pattern-Grid....however I would like to have a notation on the side so I can refer to the box in the grid by using references such as A1, B4 etc...Do you think it is possible?
There is an implementation of contrast limited adaptative histogram equalization on Imagej (Plugins =>Filter => Enhance Local Contrast) with settings for blocksize, histogram bins, max slope.
I don't know equivalent action in Gimp, similar but not the same are tone mapping algorithm like Mantiuk, Reinhard, fattal. Maybe this algorithm can be ported to Gimp as plugin, filter or Gegl action.
On some picture it can be useful to have a better contrast with blocksize to match length of picture and smaller or to get drawing effect with very smaller blocksize and histogram bins.
Here for instance a 387x259 photo with Imagej and different settings :
First row Original - settings blocksize 387, histogram bins 256, max slope 3 Second row 60/60/3 30/30/3
Edits in Photoshop such as Exposure, Curves, and Hue apply a layer over the original image making it a more versatile experience, to where reordering edit layers can produce a different outcome, and allowing one to constantly return to one specific edit after making other ones and altering it. Does GIMP work in this fashion? Or is it something too advanced for me to figure out?
I'm using GIMP through the Linux addition to my Chromebook as a photo editor since I obviously cannot install Photoshop or want to pay for it. I have no issue doing the basics and I know how layers and their opacities work but it's pretty much anything in the Color tab that I don't understand to do in a versatile manner similar to Photoshop.
