How to highlight a rectangle in Okular

Maybe you are faster highlighting with a rectangle selection instead of a text one. Maybe your pdf doesnt have text information or is an image. Or you want to highlight parts of an image inside your document. I dont care why, but this is how you do it.

I think this is a clear example of the motto of Plasma Simple by default, Powerful when needed.

Also…, why are you reading this in a post with big images and a clear title?.

Open your Okular settings by clicking on Settings -> Configure Okular… and go to the Annotations section

There click on Add and create a new one with the following settings:

• Type: Geometrical Shape
• Type: Rectangle
• Color: Pure yellow
• Opacity: 40% (this is what i like, not too bright, not too transparent)
• Shape fill: Checked
• Width: 0

After closing and opening Okular again, you can use your new rectangle highlighter from the toolbar itself.
