What is the use of ps cropping?

There are three operation methods of cutting, cropping and cropping in Photoshop CS6. Let me tell you what cropping is.

Cropping is actually a kind of cropping, which is used to trim off the edges around the entire picture. It's a bit similar to how we use a paper knife to cut off the excess white edges around it.

1. Cropping can only automatically affect the entire picture, and cannot perform selection operations;

2. It can only crop the surrounding parts of the same color, and can only crop rectangles. ;

3. Since the surrounding color may be very close to the color of the retained part of the picture, sometimes there will still be residual color.

After deletion, the image size will also be reduced, and it will be applied to the layers you selected.

The shortcut key is Alt I R, or click "Image"->"Crop"

A dialog box will pop up for cropping, and you can choose to select Color conditions, surrounding cropping area.

In the upper toolbar, you can select the size of the sampling point and the layer to be applied.

Based on transparency, you can only crop when the surrounding areas are transparent, and when the upper and lower corners are the same color.

The result of cutting is to cut off the same color parts around it.
