Automatically cut pictures

png

For example, if we want to cut out the small icon before collection, first find the layer or group corresponding to the icon, and then rename it. The point is to add a suffix to it. If you want to save a picture in png8 format, write the suffix as .png8. Similarly, if you want to save the png24 format, the suffix name is written as .png24

At this time, there will be an assets folder under the image storage directory, which will store the image sc.png just saved

jpg

Similarly, jpg format pictures are also cut in the same way. For example, we need to cut out the picture of feet

Actually, when storing images in jpg format, there is a quality selection, from 0-100. If we write the suffix name as .jpg6, it means the quality is 60. If the suffix is ​​.jpg, it means the quality is 100

Let’s first open the original picture, which is 13.6k in size. After changing the suffix to .jpg5, the size became 4.52k

2x image

If we need to adapt to the retina screen and cut out the 2x image, we can also use the automatic image cutting function. Just rename it to 200% image name @2x.jpg

First, we first check that the size of the foot image is 200*200. When we set it to 200% jy @2x.jpg5, we then check that the size of the foot image becomes 400*400, which is generated 2x picture

Similarly, the 3x picture is also done in a similar way
