Often when I put a document on the photocopier for scanning I don't get it exactly level for various reasons. How ca I straighten it out in GIMP? If I can't get it aligned right my cropped  image comes out skewed. See the two attached examples.

I have an old print that has some kind of damage on it which looks like a scattering of little red blobs.  The red blobs don't completely obliterate the image underneath, but rather they change its color.  I'm familiar with the technique of filling in missing portions of the image using nearby regions with the Heal tool.  But in this case it seems like I actually have image content in the blobs, so it seems like I don't want to replace the pixels, but rather adjust their color.  I'm wondering if there's a way to do that.   I have attached a section of the image (at full resolution) showing the blobs which are very obvious across the grass and less evident, but still visible if you look on the subject's pink shirt and neck.  

   

How would you go about doing this?

Hello,

Keep in mind that it's the first time ever that I'm using GIMP; so I've no clue how one would routinely use any basic function.


So, I want to change the color of pixels in an area of a picture from some kind of brown/purple to black. I selected the area. I opened color/map/exchange color. I selected a sample pixel of the color I want to change to black in "from color". Black is already preselected in "target color" by default. 

Then, what do I do to actually exchange the colors? I clicked on "apply" but the "exchange color" window just closed and nothing happened in my selection. The manual explain explains how to select the origin and target colors, as I wrote above but doesn't say how you actually apply the change.

Thanks in advance.

I recently moved up to the AppImage of 2.10.8. Clicking on an ARW (Sony raw) file no longer brings up Nufraw as it did in earlier releases of 2.10.

Gimp: 2.8
Windows 7

This is driving me stupid.

If I drag a text box over my image, but then realise I've forgotten to do something (erase a line / add a line / whatever) and click on a different tool (eraser / pencil / whatever) I'm left with a yellow box of 'walking ants' where my text box had previously been. With that there I can't do anything with my file (can't erase, can't draw, nothing).

For obvious reasons the first thing I did was go to Select and choose 'None' but this didn't get rid of it.

How on earth do I get rid of this dotted border so that I can continue working on my file?

Thanks in advance.

I have several pictures both in my personal users\username\gim2.8\patterns folder  and in the patterns grid/list.  I am now attempting to add three pictures (png,jpg) to that  list.  They do appear in the personal pattern folder all right but refuse to enter the pattern grid.  I have used the green refresh button with no result.  What can I do?

Hello everyone,

I came across this site: https://templatetoaster.com/tutorials/gi...ts-plugin/
which seems to suggest that by loading layerfx.2.8.py into my plugins folder, as a Windows user, I would gain the option of previewing my effects.  I followed the instructions, but it didn't work. Can anyone tell me if this is valid please?

Thank you.

Since a majority of users (here and elsewhere) seem to be on 2.10, we will consider that the "General" section is for 2.10. As a consequence:

• I have started a "Gimp 2.8" sub-forum for those who prefer vintage software
  
• I have disabled thread creation in the Gimp 2.10 forum (posts to existing threads are still possible).
  

Hi all,

I bought an Intuos One pen and tablet, which I'm trying to use on GIMP 2.1

The device is configured and working, but every time I try to use it with GIMP, I get a 'GEGL Operation' window.

Any ideas how I can use it to actually draw something?

Thanks!
