Mirror? Simple Get magic wand outline the outside of a pic cut and boxes should appear or was that something else?
Uh....not quite.
Step 1. Create half your image. It should extend to exactly halfway across the canvas
Step 2. Select the half you have made With the
rectangle select tool.
Step 3. While selected, press
cntrl-c (copy)
Step 4. press
Image>
Flip Horizontal it will flip the image.
Step 5. Press
cntrl-v and your original image should appear.
If you did it right you should have 2 identicle, mirrored images directly opposite each other. If any mistakes appear (like an empty line down the middle) can be fixed manually.
NOTE: Only apply text and letters
after doing the mirror otherwise it will be reversed.
