How to Crop an Image on the Android Tablet
One of the few, true image-editing commands available in the Android tablet Gallery app is Crop. You use the Crop tool to slice out portions of an image, such as when removing ex-spouses and convicts from a family portrait. To crop an image, obey these directions:
Summon the image you want to crop.
Touch the Menu icon.
If you can’t see the icon, touch the screen and the icon will reappear.
If the Crop command is unavailable, you have to choose another image. (Not every album lets you modify images.)
Work the crop-thing.
You can drag the rectangle around to choose which part of the image to crop. Drag an edge of the rectangle to resize the left and right or top and bottom sides. Or drag a corner of the rectangle to change the rectangle’s size proportionally.
Some versions of the Galley app may display a tool palette when you’re prompted to crop an image. Don’t mess with the palette! Just crop the image.
If you screw up cropping, cancel the operation and start over: Touch the Cancel button or the Back icon.
Touch the OK or Apply Crop button when you’re done cropping.
Only the portion of the image within the colored rectangle is saved; the rest is discarded.
There’s no way to undo a crop action after you’ve confirmed the changes (Step 5).
If you’re lucky, some versions of Gallery app keep the original image and create a new image with your crop edits. Not all Gallery app variations are so forgiving, however, so be careful when you crop!
