The following guide provides a clear overview of GIMP, with the most relevant background, details, and practical takeaways.
GIMP Overview
1. Launch GIMP and open one of your images. Scroll to the Toolbox window and click on the "Rectangular Select" tool.
2. Click a point on the image, hold down the left mouse button and drag to draw a small rectangle. The area inside the rectangle becomes your selection.
3. Scroll back to the Toolbox window and click on the "Rotate" tool to select it.

4. Return to the selection you created and click inside the selection. GIMP will open the Rotate dialog window.
5. Enter the value in the 'Angle' text box. The value you enter determines the distance that GIMP will rotate your selection. For example, if you enter '45' then GIMP will rotate the selection of 45 degrees. You can also drag the slider below the Angle text box to rotate the selection. When you move the slider, the selection will rotate. If you don't see that happen, drag the Rotate window so you can see your image on the canvas.

6. Click the "Rotate" button in the Rotate window to apply your changes.
Advice
- Delete the selection by clicking 'Select' and then clicking 'None'.
- The Toolbox tool has no display name. If you have difficulty finding, hover over a tool. GIMP will open a tooltip feature, displaying the name and description of the tool. You can learn about GIMP's new features by experimenting with new tools and see what they can do when you use them on your images. Press ' Ctrl + Z ' when you need to undo any changes you've made.

- Click ' Shift + R ' to activate the Rotate tool with a shortcut.
- The Rotate dialog window contains a "Center X" text box and a "Center Y" text box. The values ??in these boxes display the coordinates of roll and diaphragm on the spindle of the selection. You may not need to change these values, but you can do it if you want to rotate the selection around a point, different from the point that the text boxes have defined.
