Draw an arrow

  • download the arrow.scm file

  • go to directory .config/GIMP/2.10/scripts and put the file in it

  • open GIMP and draw a path

Here are the steps to draw an arrow with the plugin arrow.scm:

Load an image, and choose the Paths Tool from the Toolbox window

Test image

Choose a foreground color. This will be the color of the arrow.

Select the arrow.scm plugin from the menu at Tools > Arrow…

A new window will open that will allow you to configure the arrow parameters such as the length of wings, angle between arrow and wing, and brush thickness.

On the image, click anywhere where you want the arrow head to be and then click again anywhere where you want the arrow tail to be. When you are ready to draw the arrow, click on OK.

Put two images in the same canvas

We have two files: file1.jpeg and file2.jpeg. They can be different formats than jpeg, and they do not need both to have the same format.

An Gimp image is a number of layers over a canvas.

The idea is to extend the canvas, add the second image as a layer. Next move the layers so that they do not overlap.

Open file1.jpeg using Gimp.

Expand the canvas. Go to the menu Image, next Canvas size (or Ctrl L).

Next choose Windows, then Dockable Dialogs, then Layers. This shows the layers dialog. If all is well you have one layer. It is file1.

Now choose File, Open as Layers and open file2.jpeg.

At this point you see two layers in the Layers dialog. The image itself has become quite messy with the two images overlapping. One is file1 and the other file2. You now want to move these layers so that they no longer overlap.

Choose View, and select snap to canvas edges, that way you can align the images correctly Choose Tools, Transform tools , and next Move. You can now move the layers that is selected in the layers dialog.

Move the layers until they no longer overlap. If necessary adjust the canvas size.

last step: Image → Fit Canvas to Layers
