Cutting a transparent image

ShoeBox Extract SpritesFunction. Drag the image to the Extract Sprites icon to automatically cut the image, as shown in:
Click SettingsYou can set it in detail. Here, set Clusters Merge Sub Items to false without merging subitems, change File Name to slice‑0000.png, and click ApplyYou can. Then press SaveYou can export the cut image. As shown in:
Generate a text document that records the submap coordinates of each cut. Add the following script in the Editor directory of Unity: C # Code

In the Project view, right-click the text document and choose ShoeBox> Process to Sprites from the shortcut menu. The Sprites format of Unity is automatically imported, as shown in:
The Sprite Editor of Unity also provides the image cutting function. However, when a complex image set is encountered, the cutting process is chaotic and the ShoeBox accuracy rate is relatively high.
