1 year agoDo you mean "convert brightness to transparency" in the edit menu? I'm sorry if I'm wrong.
This converts brightness to transparency, so for example colored areas will only convert brightness to transparency. (It doesn't matter what color it is painted in)
It is mainly used when extracting only the line part from a picture drawn with black lines on white paper.
The left image below is the original image. Light blue and orange convert the brightness of the color into transparency. The white part is 100% bright, so it's completely transparent. The black part has a brightness of 0%, so it becomes opaque.- Japanese
