VIPS 8.11

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.

8.1116 Aug 2020 07:05 minor feature: Add vips_jpegload_source() and vips_svgload_source() to public C API.
8.10.110 Aug 2020 13:45 minor bugfix: Markdown - xml conversion in doc generation.
8.10.025 Jan 2020 16:05 major feature: More conformat IIIF output from dzsave regisrob . Add @id to dzsave to set IIIF id property regisrob . Add max and min to region shrink rgluskin .
8.9.110 Jan 2020 18:45 minor feature: Don't use the new source loaders for new_from_file or new_from_buffer, it. Will break the loader priority system
8.9.018 Dec 2019 09:45 major feature: Add vips_image_get/set_array_int(). Disable webp alpha output if all frame fill the canvas and are solid. Support arrays of delays for animated images deftomat . Add "unlimited" flag to svgload. Disable webp alpha output if all frames fill the canvas and are solid. Add "compression" option to heifsave lovell . Support webp and zstd compression in tiff. Loaders use "minimise" to input files earlier. Integrate support for oss-fuzz omira-sch . Add vips_switch() / vips_case()... fast many-way ifthenelse. Better const handling for arithmetic operators comparisons against out of range values. Sharpen restores input colourspace. Handle alpha in heifload / heifsave meyermarcel . Add @interpretation and @format to rawload. Nifti load/save uses double for all floating point metadata. Add vips_error_buffer_copy(). Add VipsStream: a universal IO class for loaders and savers. Jpeg, png, tiff (though not tiffsave), rad, svg, ppm and webp use the. New IO class Rewritten ppm load/save is faster and uses less memory. Add @no_strip option to dzsave kalozka1 . Add iiif layout to dzsave. Use of resolution-unit metadata on tiff save kayarre . Support TIFF CIELAB images with alpha angelmixu . Support TIFF with premultiplied alpha in any band. Block metadata changes on shared images pvdz .
8.8.025 Sep 2018 13:05 major bugfix: Update function list in docs janko-m .
8.7.121 Sep 2018 15:25 minor documentation: Update function list in docs janko-m .
8.7.025 Dec 2017 06:25 major feature: Add magicksave, save image with libMagick dlemstra .
8.6.112 Dec 2017 02:45 minor feature: Stop window new/free cycling.. faster zoom out on large images in nip2.
8.6.018 Apr 2017 03:17 major documentation: Supports fits images with leading non-image HDUs, thanks benepo.
8.5.314 Apr 2017 12:45 minor bugfix: More link ing in docs. Revise cache sizing again to help out of order errors under heavy load, thanks. Kleisauke
8.5.231 Mar 2017 09:45 minor documentation: Better behaviour for truncated PNG files, thanks Yury.
8.5.126 Mar 2017 03:17 minor documentation: Init more classes earlier, thanks David.

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.
8.2.328 Jan 2016 18:25 minor bugfix: a crash with SPARC byte-order labq vips images.
8.2.213 Jan 2016 13:05 minor feature: Changes to ease compiling C++ binding with MSVC.
8.2.102 Jan 2016 11:05 minor feature: Add a compat stub, thanks Benjamin.
