VIPS 8.3

VIPS is a small, quick and memory-conservative 2D image processing C and C++ library. It comes with over 300 functions, for arithmetic processing, histograms, convolutions, morphological operations, frequency filtering, colouring, resampling, statistics and others. It supports most common raster image formats (PNG, TIFF, JPEG, FITS, OpenEXR), or chain to ImageMagick/GraphicsMagick.

Recent Releases

8.308 Feb 2016 16:45 minor feature: Add vips_reduce*()... a fast path for bicubic downsize. Vips_resize() and vips_similarity use it when they can. Bicubic is better on 32-bit int images.
8.1.011 May 2015 06:25 minor feature: add vips_premultiply(), vips_unpremultiply(). change the alpha range rules for vips_flatten() to match vips_premultiply(). vipsthumbnail uses vips_resize() rather than its own code. vipsthumbnail uses vips_premultiply() for better alpha quality.
8.0.206 May 2015 04:05 minor feature: fix a refcount error in C++ wrapper, thanks huskier. reomve a couple of stray header decls, thanks benjamin.
8.0.126 Apr 2015 23:45 minor bugfix: Fix some compiler warnings.
8.012 Feb 2015 13:45 minor feature: remove old doc stuff add fliphor, flipver, rot90, rot180, rot270 convenience methods to Python add shift option to cast better alpha handling for 16 8 bit colour conversions
7.42.308 Feb 2015 17:25 minor feature: bump version for back-compat ABI change. added vips_image_memory, an alias for vips_image_new_memory. improvements to configure for python. remove --disable-cxx configure flag.
7.42.022 Nov 2014 08:05 minor feature: Better default resolution for PNG loading. Better PBM (one bit) load, better PFM (float) import/export. Fixed bug with vips_gaussblur() parameters.
