Collage with transparency #16

Closed Aleclock closed 2 years ago

Aleclock commented 2 years ago

Hi, I'm trying to create a collage with a destination image that contains a transparent area (I have a .png file), but when I load it the transparent area is converted into black area (or white). Is it possible to handle a transparent area where no tiles are added?

Yes, it's possible, but I need to modify my code to support this. I'll do it when I have time. It will probably take a few days.

It would be great, thanks!

Basic implementation is complete. The code is on the transparent branch (https://github.com/hanzhi713/image-collage-maker/tree/transparent). Just add --transparent for your cli command or tick the transparent masking checkbox on the GUI to use this function.

Let me know if it works or not. I'll do more testing and update the readme and examples tomorrow.

Demo: result
