How to Crop an Image on the Android Tablet
One of the few true image-editing commands available in the Gallery app of your Android tablet 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 Action Overflow or Menu icon.
If you can’t see the icon, touch the screen and the icon reappears.
Sometimes, you must choose an Edit command before you can find the Crop command.
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 Gallery 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 Done or Save button when you’re done cropping.
Only the portion of the image within the colored rectangle is saved; the rest is discarded.
The cropped image is saved in the Gallery.
On some tablets, the crop procedure is irreversible; you cannot undo the crop. Other tablets may save the cropped photo as a new photo, keeping the original.
Also look for the Crop icon in some Gallery apps. Such an icon is shown in the margin.
Some variations of the Gallery app feature the Edit icon. Touch that icon to review all the different tools for manipulating and mangling an image.
