Could you build this?
Partial The basic Compose UI gesture overlay is straightforward, but production multiplatform image cropping handling 100MP photos without OOM errors, 8 Exif orientations, and shared Kotlin Multiplatform targets across 6 platforms requires specialized graphics memory engineering.
What it would actually take: The library is written in Kotlin Multiplatform targeting Android, iOS, JVM Desktop, and Wasm. The hard part is building zero-copy or sub-sampled streaming image decoders that preserve memory across platforms (BitmapRegionDecoder on Android, ImageIO/CGImage on iOS/macOS, Skia on Desktop/Wasm) while managing matrix math for all 8 Exif rotations, smooth pinch/pan gestures, and coordinate normalization without native crash bugs or Out-Of-Memory exceptions.
