Gwenview has a few features which are available in both Browse, View, and Full Screen view. Gwenview has the capability to do basic alteration of your images.
Rotate: A rotate operation will rotate the image either to the left or to the right, depending on whether you do → (Ctrl+R) or → (Ctrl+L)
→ : This operation will reflect the image along the vertical axis, as if you were seeing it in a mirror.
→ : This operation will reflect the image upside-down (a reflection along the horizontal axis)
→ (Shift+R): This operation will allow you to shrink or expand the image. Note that if you increase the size of an image, it may appear blurry and/or pixelated.
These actions are also available on the Operations tab of the sidebar.
If you have edited one or more images a bar with additional actions is displayed at the top of the image. You can undo or redo your changes, go to the previous or next modified image and there are three options to save the changed images.
If you have installed the KIPI Plugins, a menu will be available that will allow you to perform many additional operations on your images.
