Well, true, I'm new. I didn't know Lazarus until last week, because it was recommended to me on the Paint.NET forum because it can do batch operations.
What I need is precisely what I asked for in the first post: I need to do 2 things,
- convert a series of images into layers (each layer in png);
- convert a series of pdn into jpg.
I hope it is possible to do this, I thought it was more logical to ask here than on the Paint.NET forum.
If it's the wrong section, of course, a moderator can move it to the appropriate section.
