Crop an image
Cropping an image means reducing its size be removing unwanted parts (usually around the image or borders). But this is done without resizing the image content. This may be useful if interesting part of an image is not properly centered.
1. Create a File Browser window by choosing File/New/File Browser (Ctrl+Shift+O).
2. Browse your disks and select the appropriate folder in the left pane. The media files included in the folder appear in the right pane.
3. Select the file you wish to open.
4. Double click on it or choose File Browser/Open Item (Enter) or right-click on it and choose Open in the menu.

5. First be sure the Selection Mode is the active mode. Select Image/Selection Mode (Z) if necessary.
6. Select the portion of the image you wish to keep using the mouse. A selection rectangle is displayed when done.

7. Select Image/Crop Image (C).
8. The image is cropped.
Undo the change
9. If you want to undo the crop operation, select Edit/Undo (Ctrl+Z).
10. You can also redo the change by choosing Edit/Redo (Ctrl+Y).
Save the modified image
11. As the document has been changed, you'll be prompted to save it when you'll close the window. You can only save the new image to a JPEG, BMP, PNG, JP2, GIF or PSD file.
