Spectrum:Facebook 开源的图像处理库,优化移动端图像生成

Spectrum is a cross-platform image transcoding library that can easily be integrated into an Android or iOS project to efficiently perform common image operations.

The Spectrum APIs incorporate declarative traits. This simplifies the usage for the developer by focusing on the desired outcome. At the same time it enables Spectrum to transparently choose the best execution sequence. Additionally, Spectrum makes common image operations simple by surfacing many difficult operations that are not typically exposed by platform frameworks. For example, some JPEG-to-JPEG operations like cropping are executed lossless, and disabling chroma sub-sampling when saving graphical JPEGs will lead to better quality final products.
