VIPS 8.16.0

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.

8.15.110 Jan 2024 21:04 minor bugfix: - reduceh: fix Highway path on SSE2 DarthSim - fix JPEG in TIFF colourspace for Q = 90 heman1-test - fix build with upcoming libjxl 0.9 kleisauke - jxlsave: lower min effort value to 1 DarthSim - fix build without libjpeg ionenwks - fix vips7 plugin load jcupitt - allow ".jfif" as a suffix for jpegsave casperbrike - don't let the magick sniffer hijack TIFF kleisauke - ignore BLOCKED classes in foreign map jcupitt - add locks to fftw3 calls akash-akya
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 .

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
8.308 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.
