Hi, forum newbie here (although I've been using GIMP for a few years on and off)

I have a specific task that I'm struggling with...

I'm working on producing an overlay of two old maps. One of them is rendered accurately to correspond with modern mapping (this is the one I want to use as a reference), the other a photo of an older map which is distorted.

I need to have the 'modern' map on top and have made it transparent so the older map can easily be seen through it when the modern map is overlaid on top of it. The modern map is more or less monochrome with a white background so is the obvious choice for the top layer (the older map is multicoloured and dirty so would be a poor choice for the top layer).

I now need to adjust the perspective of the older map, which is in the lower layer, to remove the distortion and line it up precisely with the modern map. This is possible, but when I try to do it I can't see the modern map on top, which I need to get the registration between the layers correct - it disappears when I select the perspective adjustment option (Shift-P).

Does anyone have any suggestions?

Many thanks, David.

I'm new to Gimp and cannot figure out how to get rid of a fuzzy tool selection mask I created (see attached photo).  I've tried various resets and unchecks, and shift-ctrl-A, and even uninstalled and reinstalled Gimp 2.10.  The mask is still there in the new installation.

I believe I was using the fuzzy selection (magic wand) tool so as to select all areas of a photo that are similar in color, so that I could change then all to a single color and then make this color transparent.  The cursor then changed into a dotted map of all these areas.

The problem is that I cannot figure out how to turn off the fuzzy selection map.  If I try to use the clone tool, I still get the fuzzy selection map (which moves around as I move my cursor). 

What I want to get is the usual circular clone cursor for selecting an area and then cloning with it.

I'm sorry if this is an idiot question but sure would appreciate some kind soul telling me what I'm doing wrong.  Thanks in advance for your assistance.

Among my plugins there are two rather similar ones which can be used to smooth a (straight-edge) path: the simple plugin

https://www.gimp-forum.net/Thread-Smooth...ple-plugin

and the better algorithm

https://www.gimp-forum.net/Thread-Making...uous-paths

which makes very smooth paths (continuous curvature).

It came to my mind that some people may miss the better plugin just because it is called "G2-continuity" and hardly anybody knows what that means. So, just to draw peoples' attention to the plugin, I made this new thread where the title contains the words "smoothing" and "better". I hope this is not against any netiquette or forum rules. The two plugins are found at:

http://kmarkku.arkku.net/Path_modify_fil...aster.html

under the names "Simple smooth" and "G2-continuity". The sites above contain some instructions and discussion.

I am looking to stretch out my 256 color positions in the indexed color map using two colors. I can select the individual boxes and change the color, however, I was hoping to select all boxes at once and define the darkest and lightest box colors and then let gimp spread out the color across the boxes. In photoshop I can just select the first box and then drag until the last, is there any similar option?

I've been having this issue ongoing for quite some time... well I should more say a collection of issues that are all related and are on and off when they occur.

• When trying to zoom in/out with CTRL + mousewheel nothing happens until I click on something like the ruler bar.
  
• When selecting a different tool sometimes it won't actually switch to them until I double click it or do something else like clicking on the ruler bar or changing to a different layer in the image.
  
• Using the pencil doesn't highlight the area where the pencil is until I actually click on the image and end up accidentally putting a dot on the image, same applies when attempting to draw a straight line when holding down CTRL or when trying to draw out an area using one of the select tools.
  

Hi,
      I am using GIMP 2.10.22 . I have created a thumbnail. The problem is I want to add a picture image of the hard disk two times. For example, I want to show Hard Disk-1 and Hard Disk -2 (Both images will be the same).
The hard disk -1 is on the left side I want to show the same image of the hard disk on the right side. I am attaching the source file herewith. The image of the hard is I get https://pixabay.com/vectors/hard-disk-st...er-159264/
Please guide me that how may I do it?

I want to print two 5 x 7 pics on 8.5 x 11 paper but oriented so that the pics are side by side. 7 inches along the 8.5 dimension and two 5 inches, total 10 inches, along the 11 inch dimension. Can Gimp do this? I'm having trouble figuring this out. If Gimp can't do this what other software would be good at this? 
Thanks.

(Of course I could just get 5 x 7 paper but I want to make use of my 8.5 x 11 paper.)

Perhaps it's a hint for me to try Python-fu. I've confirmed that the attached script works in Gimp 2.10.
The output of BIMP, though, is an unchanged image.
Am I missing something basic about BIMP?

(define (make-vignette color size opacity img)
 
  (let* ((width (car (gimp-image-width img)))
         (height (car (gimp-image-height img)))

         )

    (gimp-context-push)
    (gimp-image-undo-group-start img)

    (gimp-image-select-ellipse img 0 65 50 (/ width 1.3) (/ height 1.3))

Hello good people of this wonderful forum,

I have been using gimp for many years with just a mouse and keyboard but recently got a Huion tablet to help me paint.

Since plugging it in and messing with the paintbrush tool I have realized I don't really understand the settings of the paintbrush tool. Using the tablet has changed my paintbrush settings and I do not know how to return them to what I am used to using.

When I draw a line with the paintbrush, with the mouse or the tablet I get a line that is broken up and the size of the line changes depending on the speed I move.

I know this is probably a simple fix, but can anyone help me please?

thank you

Andrew

I tried to install Resynthesizer Plugin, however when I went to Filters/enhance all the tools are greyed out.
Does it work in GIMP 2.10.30? I vaguely remember reading somewhere that it doesn't! If that is true what
would be the last version of GIMP where it works?

I followed the instructions from this video to install it.

Any feedback would be gratefully received.
Thanks
