•    C

---

libvips is a 2D image processing library. Compared to similar libraries, libvips runs quickly and uses little memory. libvips is licensed under the LGPL 2.1+. It has around 300 operations covering arithmetic, histograms, convolutions, morphological operations, frequency filtering, colour, resampling, statistics and others. It supports a large range of numeric formats, from 8-bit int to 128-bit complex. It supports a good range of image formats, including JPEG, TIFF, PNG, WebP, FITS, Matlab, OpenEXR, PDF, SVG, HDR, PPM, CSV, GIF, Analyze, DeepZoom, and OpenSlide. It can also load images via ImageMagick or GraphicsMagick.

libvips is a demand-driven, horizontally threaded image processing library. Compared to similar libraries, libvips runs quickly and uses little memory. libvips is licensed under the LGPL 2.1+. It has around 300 operations covering arithmetic, histograms, convolution, morphological operations, frequency filtering, colour, resampling, statistics and others. It supports a large range of numeric formats, from 8-bit int to 128-bit complex. Images can have any number of bands. It supports a good range of image formats, including JPEG, TIFF, PNG, WebP, FITS, Matlab, OpenEXR, PDF, SVG, HDR, PPM, CSV, GIF, Analyze, NIfTI, DeepZoom, and OpenSlide. It can also load images via ImageMagick or GraphicsMagick, letting it load formats like DICOM.

graphicsmagick-stream - Fast convertion/scaling of images using a pool of long lived graphicsmagick processes

•    Javascript

---

If you install ghostscript as well you will be able to convert pdfs to images by simply piping in a pdf and setting output format to jpeg (or another image format).If you are rendering a multipage pdf scale.height will set the height of each page. To force scale.height to donate the height of the entire image set scale.multipage = true.

resizer - Simple image resizer and thumbnail generator for node.js as a stream

•    Javascript

---

Resizer is a thumbnail generator and image resizer for node with a transform stream interface. Its goal is to be simple and fast. Current implementation is based on GraphicsMagick and adopt smart tricks to speed up conversione and provide better images so you don't need to know all graphics magick options and internals. It is based on the Stream 2 API, so it will not work on node v0.8. If you want node v0.8, please submit a pull-request.
