This is a very simply question, but one that I have been struggling to find an answer to: How can I put a box outline around something in GIMP? So that you can easily circle (but with a rectangle or square and not a circle) something in an image that you want to point out to someone. Or is there a better tool which would easily allow it without lots of manual drawing if it cannot easily be done in GIMP? When on Windows I would use Paint for this as I could not find an option in GIMP, but now in Ubuntu I can't find anything else to do it in.
Select the area you would like to outline with the rectangle select tool, go to Edit > Stroke Selection. You will get a dialogue. Choosing Solid Line will create an outline using the currently selected foreground color. Choosing With a Paint Tool will give you more creativity.
Create new layer.
Rectangle select for outer wall of rectangle.
Bucket fill that rectangle or paste a texture if you want to use a texture for your outline.
Edit shrink selection by the width you want for your rectangle.
Right click on the layer and merge the layer down.
You have answers for gimp, but
I also find gimp a bit hard work for this sort of thing. I don't have windows so I don't know what its Paint is like, but I can recommend the very simple and old
xpaint, the even simpler gnome version
gpaint, or my favourite for over 10 years (and more sophisticated),
xfig, all in ubuntu.
A GIMP Alternate:
A simple tool for drawing rectangles and ellipses on pictures is already included in Ubuntu
- Open the image in LibreOffice Draw. You can do this by first opening Draw and then opening the image in it. Or you can right click on the image and choose Open with > Other Applications > Show other applications.
- Look for Basic Shapes in the left hand tool bar and click the down arrow next to it. See Step 2 in the picture below:
- Select Frame or Ring shape. You can reduce the width of the ring and squish to to an ellipse if you want.
Hope this helps
Select Filters > Render > Gfig... From there you can draw boxes and other shapes boxes in various styles.
