I just installed Linux Mint 19.3 with Cinnamon desktop on a Thinkpad with resolution 3840x2160.  I have GIMP 2.8.22 installed.  The tool icons are too small.  How do I make them larger?  Thank you in advance for your help.

Hi there, back again with more challenging graphic, at least for me.

I have a 10,000 points of co-ordinate x-y. 
Is there anyway, i can import my points in, and the path start drawing the lines and then interpolate using some polynomial / bezier curve ?
Here is a sample graph, when i plot it in excel.
   

Hi

I got this texture template where I have divided up the image to layers for the texture for a certain part of my model. I unfortunately forgot to save the current structure's texture to my project and had just exported it as a flat image. I have the structure but in a transparent canvas and a flat image. So I was wondering if there is a faster way to convert the flat image to my layer structure except going through them, one by one, and manually move the flattened image textures to my layers?

Hi, I am trying to make a graident path in gimp. I am trying to do gradient gradient across stroke (like in adobe illustrator) rather than gradient along stroke. The problem is that when I stroke path in gimp, it gives me the option to stroke along path, but not across. So my stroke ends up looking like the one above. But I want it to look like the one below.

When I try to drag it it only leaves separated dots vs a smooth line. Is there a way to fix it

Basically title says it all. I know there's a command in preferences to remember window position for multi-docks, but this does not seem to work when 2nd monitor is involved.

Or am I missing something?

Thanks!


Oops found it already!! I just had to tick that "open windows on the same monitors". I didn't get that on the 1st take, now it's logical and it works.

I have hundreds of scanned pages from a large 100 year old book that need sized consistently. I'm using Gimp 2.8.10

Currently I select the portion of the page left to right that has text and the very edge of the page top and bottom.

I then select grow by 250 pixels

then crop to selection

then canvas size 2000 px by 3300 px, CENTERED

then mode grayscale

then levels 50, .5, 200

the result is exactly what I need

I don't know anything about writing scripts. Can this all be done with a single click after the selection is made? If so, how?

Thanks Sandy

When I try on the one with the title (the first) it says "cannot subtract from an empty selection"
On the one without (second) when I first open the file it says "Execution error for procedure 'gimp-image-set-color-profile': ICC profile validation failed: Color profile is not for grayscale color space" whatever that means. When I press ok then try to fuzzy select, it says the same thing as the other file. Why does it do this?
Ok doesn't seem to let me upload 2 files at once...I'll just upload the 1st then.

Firstly, I am a total novice with sort of stuff so be kind....

What  I need help with is as follows

I construct card buildings which are printed on to paper before being fixed to card and cut out. Each sheet has certain parts of the building, walls, roofs, doors etc
What I need help with is I want to just change the colours of the doors for example which are a blue colour. A friend has done this by getting the page on screen selecting the area to change, by just clicking on the door colour, and selecting a new colour, so nothing changes except the area chosen
This all seems easy but not to me!!

Help needed and if possible in simple terms

Thanks Steve
