My daughter has drawn a picture on white paper using a very fine black pen. It is a complex forest but for the purposes of this question we may as well imagine that she has drawn a fine grid of squares, each a few millimetres wide, on a piece of A4 paper (210x297mm). If we scan the picture with a scanner we will be able to turn it into a jpeg (or a pdf) and open this jpeg in gimp 2.10.

She has made pictures like this in the past and then changed all the white to red using the "fill" functionality of gimp, carefully going through individual areas and clicking on each. But in this situation there are so many small areas that she will clearly be better off using some sort of automation. She wants all the "white" of the jpeg (which will of course translate to many slightly different RGB colours) to turn red (my understanding is that she would be fine if all the red were precisely FF0000). So basically she wants to look at every pixel and decide whether it's nearest to "white" or "black" and turn all the white pixels red.

Can this be done in Gimp 2.10?

If the correct answer to this is "look in the manual" then I apologise, please point me to the right place. We have only just started using Gimp and it is a huge piece of software which she is attempting to learn by doing and I'm attempting to help even though I know very little about the software.

I have 2 questions

1. How to make a specific key in a keyboard photo of a specific colour ?

ie, all the keys are white.


2. Is there any easy way to change the key colour in the image below

   

Is there any method to change the skin fairness of a person from dark to fair and vice versa ? Since there was a method which very easy to emboss one face over another, I was wondering whether something like that is available for the skin tone as well.

I'm trying to select this frog with the fuzzy tool at 100 to put an outline on it, but I don't want an outline on the enclosed arm area on the left frog. I tried pressing control and clicking on the area which usually works but it doesn't here. I even played around with the threshold but it didn't make any difference, at a normal 15 it still has this problem. Not sure what I'm doing wrong since deselecting area usually works.

I drew a simple line drawing with a marker on a transparency sheet.
Then I scanned it to create a digital image of the drawing on my computer.
Now I would like to do 2 things with the image:

1) Make the image solid black on a white background... Removing shade and color variance while retaining image sharpness
2) Make the program show all the little vector points so I can smooth out the line imperfections 1 by 1.

I'll include the drawing in case it helps.

   

Hello Everyone,

I've switched over to Gimp from Photoshop and the process here just seems insanely bulky. Am I missing something? I've created several custom brushes and dynamics, but each needs to be selected separately every time I switch to a different brush, and every time I switch between the Pencil, Paintbrush, and Eraser tools. Is it possible to link custom brushes to the Pencil, Paintbrush, and Eraser tool? Is it possible to link custom dynamics to custom brushes? If not, how do you guys handle your workflow???

Thanks,
RITA

so i just switched from 2.8 to 2.10 from https://portableapps.com/apps/graphics_p...p_portable



1st thing
i miss hue-saturation tool from toolbox (edit > preferences > toolbox) if any 1 know folder location of tools i believe i could just copy and paste it from older version
since that exact same thing worked with theme and language folder
or maybe its gone forever?

2nd thing
on 2.8 pressing X (the one in upper right corner of whole window) while i had any image open (or multiple images) did just close last active image and then when all images are closed X was well closing gimp itself
but now X brings window that warns me there are images with unsaved changes and do i want to discard them
then just closes if i chose to discard
my question here is is there a way/option to revert it back to as it was in 2.8 like i described above?

Brand new to this.  This is basic, but I've been through several tutorials and can't seem to figure this out, everything involves manually tracing the image which seems impossible to me by mouse.  

How do I change the color from white to something else?

Thanks so much!

I am using GIMP 2.10.14 in Windows 10 64bit.  For whatever reason, GIMP will not open any png files.  This includes those I have created by exporting as png and then trying to open them back into GIMP.  Other packages seem to have no trouble opening them.  If I use other packages to convert png files to jpg, GIMP will open them.

I have tried completely uninstalling and reinstalling GIMP and I have tried to bring png files into GIMP with - Windows 'open with', and GIMP open file.  Nothing works.  It appears to be a permission problem.  See below.

Please help.    

I did this years ago, but I've forgot now

cutting the face of one person and merging it onto another one.


I remember that there was a plugin or something to handle the edge

Would anyone tell me??
