Canon refers to cropping as “trimming" in the Digital Photo Professional editing application. You can trim a section of an image to enlarge or reduce, or you can crop a section of an image to remove the outer edges. For example, if you captured a snapshot in vertical mode, you can trim the black space surrounding the shot to keep only the image using the Trimming Angle tool in the DPP application. Note that you can crop the image in the Trimming Angle Adjustment window and print the trimmed version, but the original image is not actually trimmed until the file is converted and saved.

Step 1

Open the image to edit in the Digital Photo Professional application.

Step 2

Click the “Trimming Angle” option in the top tool bar. The Trimming/Angle Adjustment window displays over the image.

Step 3

Slide the “Angle” slider bar in the right panel to adjust the angle of the image before trimming. The rotation can range between -45 and +45 degrees. Click “Rotate Left” or “Rotate Right” to rotate the image in 90 degree increments.

Step 4

Click the “Aspect Ratio” drop-down box in the right panel, then click “Free” to manually adjust the size of the trimming adjustment window by dragging the corners of the Trimming Angle Adjustment window. You can also click a specific aspect ratio to enlarge or shrink the image. For example, click “3:2“ to reduce the trimming window size by one-third.

Click “OK” to trim the image and return to the Edit screen. Note that the cropped image is not yet saved as a file. You can print the cropped image from the Edit window, but you must explicitly convert and save the cropped version of the graphic. To save the cropped section as a file, click the “File” option on the top tool bar, then click “Convert and Save.” The Convert and Save dialog box opens. Click the “Save In” drop-down box and select a location for the image. Type a name for the image, then click the “Save as Type” drop-down box. Click the desired file format and click “Save.” The cropped image is saved in the designated location.
