Questions tagged [sharp]

Questions about sharp, a Node.js image processing library to resize, crop and optimize JPEG, PNG, WebP and TIFF images.

The typical use case for this high speed module is to convert large images in common formats to smaller, web-friendly JPEG, PNG and WebP images of varying dimensions.

Resizing an image is typically 4x-5x faster than using the quickest [tag:imagemagick and settings.

Colour spaces, embedded ICC profiles and alpha transparency channels are all handled correctly. Lanczos resampling ensures quality is not sacrificed for speed.

As well as image resizing, operations such as rotation, extraction, compositing and gamma correction are available.

Most 64-bit OS X, Windows and Linux (glibc) systems running Node versions 4, 6, 8 and 9 do not require any additional install or runtime dependencies.
