Steps for adjusting a whiteboard photo in Gimp
Posted by jpluimers on 2015/12/28
A long time ago, I wrote about Steps for adjusting a whiteboard photo in Paint.NET.
GIMP does an even better job with these steps:
Once: install the clean-whiteboard-photo script
- Visit https://github.com/kyleburton/sandbox/blob/master/gimp/clean-whiteboard-photo.scm
- Click “raw”
- Hit “Ctrl-S” to save the file as file-type “*.txt” and file-name “%temp%\clean-whiteboard-photo_scm.txt”
- Go to the folder “%temp%”
- In there,
- select the firle “clean-whiteboard-photo_scm.txt”,
- change it into “clean-whiteboard-photo.scm”,
- copy the file
- Go to the folder “C:\Program Files\GIMP 2\share\gimp\2.0\scripts”
- Paste the file (you need to confirm Administrator rights through UAC)
The above steps will add this menu option to GIMP: menu “Filters” -> “Whiteboard” -> “Clean whiteboard photo”
For every picture: make it less ugly
- Start GIMP 2
- Open the picture
- With the “Rectangle Select” Tool (R), select the area of the whiteboard that you want to enhance
- If the area is not completely rectangular, make the selection large enough to cover everything needed in the final picture
- Only when the selection needs adjustment to make it rectangular:
- Choose the “Perspective” Tool (Shift-P)
- Drag the incorrect corners until the selection is rectangular
- In the “Perspective” tool window, click “Transform” to confirm
- The selection now is not rectangular any more, so deselect everything:
- In the menu, choose “Select” -> “None” (Shift-Ctrl-A)
- With the “Rectangle Select” Tool (R), select the area of the whiteboard that you want to enhance
- In the menu, choose “Image” -> “Fit canvas to selection”
- In the menu, choose “Filters” -> “Whiteboard” -> “Clean whiteboard photo”
- Click next to the selection to confirm the cleanup
- In the menu, choose “File” -> “Export”
