Support for KMP

[phillipsk]

Java/Android compose ui tooling library references are preventing the library from being a pure kotlin multiplatform library

@phillipsk Thank you for creating an issue.

I am not familiar with KMP, so please let me know. I don't think the zoomable library depends on ui-tooling, since ui-tooling is only used in the app module. How should I deal with this?

It's mainly build system changes. Mostly going to be on the gradle build files and publishing. A good start is adding the kotlin multiplatform gradle plugin and moving all of the library code to commonMain.

You might hit an issue with @FloatRange annotations if they aren't a KMP module. I've successfully used your project in a Compose multiplatform project of mine. Can confirm it works in both iOS and Android.

@amrfarid140 You mean you forked it and change the build system, right? Otherwise, I don't see how it could work on iOS side.

[amrfarid140]

Yes @romainbsl that's what I meant.

@usuiat I probably can help providing Compose Multiplatform support. I'll prepare a PR

[usuiat]

@romainbsl Thank you! I'm looking forward it.

Is there any progress in this subject?

[usuiat]

@szczepanski-k I have released v2.0.0-beta01 that supports iOS. https://github.com/usuiat/Zoomable/releases/tag/v2.0.0-beta01

I recommend a similar image zooming library ZoomImage (https://github.com/panpf/zoomimage).

It perfectly supports Compose Multiplatform and Android View, supports zooming, panning, positioning, rotation, and subsampling of large images. It also integrates image loaders such as sketch, glide, picasso, coil, etc.

The most important thing is that it can zoom large images without memory overflow
