Spectrum is a cross-platform image transcoding library written in portable C/C++ that integrates into Android and iOS projects to perform common image operations efficiently. Its declarative trait-based API lets developers specify desired output characteristics while Spectrum handles orchestration, including lossless JPEG operations and codec-level quality options.
Use cases
- transcode images between jpeg png and webp on mobile
- crop jpeg images losslessly on android or ios
- reduce image file size while keeping quality in a mobile app
- disable chroma sub-sampling when saving graphical jpegs
- handle exif metadata correctly during image operations
- add custom image codec support via a plugin architecture
When to choose
- you need efficient, high-quality image transcoding in an Android or iOS app
- you want lossless JPEG operations like cropping or rotation
- you need codec-level control not exposed by platform frameworks
- you want a portable C/C++ core you can wrap for other platforms
When to avoid
- you only need basic image loading and display (use platform frameworks or Fresco/Glide)
- you need server-side or desktop image processing without writing wrappers
- you need actively developed features - the project sees infrequent releases
