v1.8.0

Notable changes

• VImage.newFromMemory and VImage.writeToMemory now both use the FFM MemorySegment API to avoid unnecessary copies to/from a ByteBuffer, and allow operating on multi-gigabyte images
  • Note that you can still use MemorySegment.ofBuffer to continue to use a ByteBuffer as input, or MemorySegment.ofArray to input a Java byte[] array
  • See the Java MemorySegment API for more helper methods to various common Java types
• The README now includes an Operationalisation section describing how to optimise memory usage, enable and disable fuzzed libvips methods, and optionally use jemalloc

Full Changelog: v1.7.0...v1.7.1

v1.7.0

Notable changes

• Adds support for libvips header operations, including access to things like ICC Profiles, EXIF data, and embedded preview images (see image for sample, libvips docs)
• Removes long-deprecated getUnsafeAddress and asByteBuffer methods (use getUnsafeStructAddress and asArenaScopedByteBuffer instead)
• Removes accidentally included "deprecated" libvips operations (specifically removes avifsaveTarget, cache, magicksaveBmp, pbmsaveTarget, pfmsaveTarget, pgmsaveTarget, pnmsaveTarget internal operations)
  • Note that there is no lost functionality here - these methods are internal libvips helper methods for other operations - see discussion

v1.4.0

Breaking change 💥

#129 includes a fix for a strange API interaction that required you to create a new, blank VImage before being able to use certain operations that don't actually reference it. The functions that call these operations are now static, and require an arena to be passed.

For example, VImage.thumbnail is now a static method. This direct thumbnail mechanism is preferred, and offers quality improvements, as noted in the docs for vips_thumbnail_image. An example of usage is available in the samples.

All affected VImage functions are listed here: analyzeload, arrayjoin, bandjoin, bandrank, black, composite, csvload, csvloadSource, eye, fitsload, fitsloadSource, fractsurf, gaussmat, gaussnoise, gifload, gifloadBuffer, gifloadSource, grey, heifload, heifloadBuffer, heifloadSource, identity, jp2kload, jp2kloadBuffer, jp2kloadSource, jpegload, jpegloadBuffer, jpegloadSource, jxlload, jxlloadBuffer, jxlloadSource, logmat, magickload, magickloadBuffer, maskButterworth, maskButterworthBand, maskButterworthRing, maskFractal, maskGaussian, maskGaussianBand, maskGaussianRing, maskIdeal, maskIdealBand, maskIdealRing, matload, matrixload, matrixloadSource, openexrload, openslideload, openslideloadSource, pdfload, pdfloadBuffer, pdfloadSource, perlin, pngload, pngloadBuffer, pngloadSource, ppmload, ppmloadSource, radload, radloadBuffer, radloadSource, rawload, sdf, sines, sum, svgload, svgloadBuffer, svgloadSource, switch1, text, thumbnail, thumbnailBuffer, thumbnailSource, tiffload, tiffloadBuffer, tiffloadSource, tonelut, vipsload, vipsloadSource, webpload, webploadBuffer, webploadSource, worley, xyz, zone.
