Fixed

Fixed

• Add missing property canvas to the CanvasRenderingContext2D type

Fixed

• Fix Assertion failed: (object->InternalFieldCount() > 0), function Unwrap, file nan_object_wrap.h, line 32. (#2025)
• textBaseline and textAlign were not saved/restored by save()/restore(). (#1936)

Fixed

• Fix actualBoundingBoxLeft and actualBoundingBoxRight when textAlign='center' or 'right' (#1909)
• Fix rgba(r,g,b,0) with alpha to 0 should parse as transparent, not opaque. (#2110)

Added

Fixed

• rgba(r,g,b) with no alpha should parse as opaque, not transparent. (#2029)
• Typo in PngConfig.filters types. (#2072)
• createPattern() always used "repeat" mode; now supports "repeat-x" and "repeat-y". (#2066)
• Crashes and hangs when using non-finite values in context.arc(). (#2055)

• Add User-Agent header when requesting remote images (#2099)

Fixed

• Wrong fonts used when calling registerFont multiple times with the same family name (#2041)

Fixed

• All exports now work when Canvas is used in ES Modules (ESM). (#2047)
• npm rebuild will now re-fetch prebuilt binaries to avoid NODE_MODULE_VERSION mismatch errors. (#1982)

Fixed

• Stringify CanvasGradient, CanvasPattern and ImageData like browsers do. (#1639, #1646)
• Add missing include for toupper.
• Throw an error instead of crashing the process if getImageData or putImageData is called on a PDF or SVG canvas (#1853)
• Compatibility with Typescript 4.6
• Near-perfect font matching on Linux (#1572)
• Fix multi-byte font path support on Windows.

Changed

• Refactor functions to classes.
• Changed DOMPoint() constructor to check for parameter nullability.
• Changed DOMMatrix.js to use string literals for non-special cases.
• Remove semicolons from Dommatrix.js.
• Update nan to v2.15.0 to ensure Node.js v14+ support.
• Clean up inf/nan macros and slightly speed up argument checking.

Added

• Added deregisterAllFonts method to free up memory and reduce font conflicts.

Fixed

• Support Apple M1 Homebrew install that puts canvas install library files in /opt/homebrew/lib

Changed

• Upgrade dtslint
• Upgrade node-pre-gyp to 1.0.0. Note that if you are using special node-pre-gyp
  features like node_pre_gyp_accessKeyId, you may need to make changes to your
  installation procedure. See https://github.com/mapbox/node-pre-gyp/blob/master/CHANGELOG.md#100.
• Add Node.js v16 to CI.
• The C++ class method nBytes() now returns a size_t. (Because this is a C++
  method only, this is not considered a breaking change.)

Added

• Add support for inverse() and invertSelf() to DOMMatrix (#1648)
• Add support for context.getTransform() (#1769)
• Add support for context.setTransform(dommatrix) (#1769)

• Fix Pango logging "expect ugly output" on Windows (#1643)
• Fix benchmark for createPNGStream (#1672)
• Fix dangling reference in BackendOperationNotAvailable exception (#1740)
