Q: I made a signature map in PHOTOSHOP, but I forgot to set the background to be transparent, so the background is always a white square. How can I ask?
1, use the magic wand tool to operate,-> Copy-> new file (background set to transparent)-> paste and save as GIF format. 2. Lasso tools. According to the actual situation, you can choose normal mode or magnetic lasso tool or take out the signature. If the signature is too complicated, just make a new one. Remember to make the background transparent!
