GIMP: Crooked Images

Sometimes when you scan your work it gets a little crooked. Be sure to fix this so that your artwork can be more presentable.

First open your file. You can do this by going to File > Open and using the explorer window to navigate to your artwork image. See below our example of a crooked image.

Next, select the Rotate Tool in the toolbox:

Now in the window with your artwork, click and drag your mouse. Adjust the position of the artwork to your liking and release the mouse button. You should have something like this with a rotate dialog box nearby.

Click on Rotate in this dialog box and your rotation selection will be applied.

This should result in an image with some transparency as indicated by the checkerboard. Well we can't have transparency so we'll have to fix that.

You'll need to fix the transparency by flattening the image. You can do this by going to Layer > Transparency > Remove Alpha Channel in the artwork window.

And now you have your finished image! Don't forget to save it!
