Straighten Horizons

Hi,

I have just installed GIMP v2.8.22

I may have missed this function in the help system.

is there an easy way to Straighten Horizons?

i can use the ROTATE tool but is there a LINE DRAWING TOOL?

Basically is there a way to draw a line along the horizon in the photo using the mouse and have GIMP make this the horizontal axis?

Thanks

The standard way is the Rotate tool in 'Corrective (Backward)' mode, line the grid up with the horizon, click rotate, and the image is rotated accordingly.

However, to draw a 'line' you need a script. One attached 'auto-rotate.scm' **unzip** it pop it into your Gimp profile scripts folder

Windows C:\Users\"yourname"\.gimp-2.8\scripts

or Linux ~.gimp-2.8/scripts

Usage: Draw a **path** along the horizon, then apply the script, Layer -> Auto-Rotate

Thank you.

That works a treat - once i worked out how to get a usable path.

Is there anyway of making a toolbox button (or keyboard short-cut) to make it easier to access the Auto-Rotate function, instead of right clicking, selecting layers, then selecting auto-rotate?

Thanks again.

Most 'extra' Gimp plugins and scripts can be assigned a shortcut key. Problem is there are not many keys that are **not** assigned.

The best list of Gimp shortcuts I know is here:

http://clownfishcafe.blogspot.co.uk/p/gimp-28-shortcuts.html and gives unassigned keys G J V W Y 6 7 8

The Gimp docs for shortcuts is https://docs.gimp.org/en/gimp-concepts-shortcuts.html which leaves a bit to be desired.

Check the screenshot:

1. Edit -> Keyboard Shortcuts to open the editor.

2. Type in a search pattern, say auto

3. You will find that Autorotate is marked 'disabled' click on that and type in (say) j

4. To keep between sessions tick the 'Save....on exit' box

Now after you have drawn your path, hit the j key and the script will activate.

Thank you again.

I did look in the keyboard short cut but didn't find auto-rotate, and i completely didn't notice that there was a search option.

thanks again.

This program does quite a lot.

Goodbye Adobe.
