3.1.2

Fixed

• Fix crash when setting width/height on PDF, SVG canvas (#2520)

3.1.1

This release also introduces arm64 prebuilds for Linux!

Fixed

• Fix a crash when SVGs without width or height are loaded (#2486)
• Fix fetching prebuilds during installation on certain newer versions of Node (#2497)
• Fixed issue with fillText that was breaking subsequent fillText calls (#2171)
• Fix svg rendering when the image is resized (#2498)
• Fix measureText with direction rtl textAlign start/end
• Fix a crash in Node 24, due to external memory API change (#2514)

3.1.0

• Replaced simple-get with Node.js builtin fetch (#2309)
• ctx.font has a new C++ parser and is 2x-400x faster. Please file an issue if you experience different results, as caching has been removed.
• The restriction of registering fonts before a canvas is created has been removed. You can now register a font as late as right before the fillText call (#1921)

Added

• Support for accessibility and links in PDFs
• ctx.direction is implemented: 'rtl' or 'ltr' set the base direction of text
• ctx.textAlign 'start' and 'end' are now 'right' and 'left' when ctx.direction === 'rtl'

Fixed

• Fix a crash in getImageData when the rectangle is entirely outside the canvas. (#2024)
• Fix getImageData cropping the resulting ImageData when the given rectangle is partly outside the canvas. (#1849)

3.0.1

Fixed

• Fixed accidental depenency on ambient DOM types

3.0.0

This release notably changes to using N-API. 🎉

Breaking

• Dropped support for Node.js 16.x and below.

Changed

• Migrated to N-API (by way of node-addon-api) and removed libuv and v8 dependencies
• Change from node-pre-gyp to prebuild-install
• Defer the initialization of the op variable to the default switch case to avoid a compiler warning. (#2229)
• Use a default switch case with a null statement if some enum values aren't suppsed to be handled, this avoids a compiler warning. (#2229)
• Migrate from librsvg's deprecated rsvg_handle_get_dimensions() and rsvg_handle_render_cairo() functions to the new rsvg_handle_get_intrinsic_size_in_pixels() and rsvg_handle_render_document() respectively. (#2229)
• Avoid calling virtual methods in constructors/destructors to avoid bypassing virtual dispatch. (#2229)
• Remove unused private field backend in the Backend class. (#2229)
• Add Node.js v20 to CI. (#2237)
• Replaced dtslint with tsd (#2313)
• Changed PNG consts to static properties of Canvas class
• Reverted improved font matching on Linux (#1572) because it doesn't work if fonts are installed. If you experience degraded font selection, please file an issue and use v3.0.0-rc3 in the meantime.

Added

• Added string tags to support class detection
• Throw Cairo errors in canvas.toBuffer()

Fixed

• Fix a case of use-after-free. (#2229)
• Fix usage of garbage value by filling the allocated memory entirely with zeros if it's not modified. (#2229)
• Fix a potential memory leak. (#2229)
• Fix the wrong type of setTransform
• Fix the improper parsing of rgb functions issue. (#2300)
• Fix issue related to improper parsing of leading and trailing whitespaces in CSS color. (#2301)
• RGB functions should support real numbers now instead of just integers. (#2339)
• Allow alternate or properly escaped quotes within font-family names
• Fix TextMetrics type to include alphabeticBaseline, emHeightAscent, and emHeightDescent properties
• Fix class properties should have defaults as standard js classes (#2390)
• Fixed Exif orientation in JPEG files being ignored (#1670)
• Align DOMMatrix/DOMPoint to spec by adding missing methods
