The problem to be solved this time is: "Process the picture to be transparent and eliminate aliasing."
I have solved this problem before, but the solution is nothing more than selecting the magic wand and deleting it, or directly using the eraser.
Also because my skills are not deep enough, but the pictures I processed sometimes have obvious "jags".
Today I learned a trick from the master LY, and the record is as follows:
1. First, take a magic wand and other tools to deal with it, It is possible that there is aliasing, go to the next step to deal with the aliasing operation.
2. Ctrl-click the layer to be anti-aliased to select it.
3. Click the "Add Layer Mask" button in the layer panel.
Note that it is not the "Edit in quick mask mode" in the tool panel.
4. Select the filter [Blur->Gaussia Blur] , the parameter usually uses "1"
5. Select [Image->Adjustments->Levels] to adjust the image level. Adjust to a satisfactory result, and then end.
