[Question] Composing multiple images

[jakenuts]

Is overlaying multiple images possible, and if so what would be the recommended way of achieving that? I gave multiple watermark calls a try and it did overlay them but the intermediate overlay lost it's transparency. I know this is a bit far afield for the library so "not today buddy" is a good answer.

Thanks!

Multiple overlays should work fine - perhaps we need more integration tests. Can you share your code/json and source images?

Here is an app that demonstrates what I was seeing. It loads a "canvas" and then overlays three transparent color-grid pngs and saves the result to another png file. If the canvas is jpg, the watermarks all retain their transparency. If the canvas is a png, the first watermark is drawn without transparency. After running you can see the different outputs in the images folder.

Thanks!

This has been fixed in 0.7.22. You can switch to the Imageflow.AllPlatforms package or replace your Imageflow.NativeRuntime.* dependencies.
