2.8.0

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.

Upgrade node-pre-gyp to v0.15.0 to use latest version of needle to fix error when downloading prebuilds.
Don't throw if fillStyle or strokeStyle is set to an object, but that object is not a Gradient or Pattern. (This behavior was non-standard: invalid inputs are supposed to be ignored.)

Fixed

Ignore maxWidth in fillText and strokeText if it is undefined
Fix crash (assertion failure) in Node.js 12.x when patterns or gradients are used
Fix crash (check failure) in Node.js 12.x when using RGB16_565 format. (The underlying arraybuffer was incorrectly sized.)

2.0.0

Upgrading from 1.x

// (1) The Canvas constructor is no longer the default export from the module.
/* old: */
const Canvas = require('canvas')
const mycanvas = new Canvas(width, height)
/* new: */
const { createCanvas, Canvas } = require('canvas')
const mycanvas = createCanvas(width, height)
mycanvas instanceof Canvas // true

/* old: */
const Canvas = require('canvas')
const myimg = new Canvas.Image()
/* new: */
const { Image } = require('canvas')
const myimg = new Image()

// (2) The quality argument for canvas.createJPEGStream/canvas.jpegStream now
//     goes from 0 to 1 instead of from 0 to 100:
canvas.createJPEGStream({ quality: 50 }) // old
canvas.createJPEGStream({ quality: 0.5 }) // new

// (3) The ZLIB compression level and PNG filter options for canvas.toBuffer are
//     now named instead of positional arguments:
canvas.toBuffer(undefined, 3, canvas.PNG_FILTER_NONE) // old
canvas.toBuffer(undefined, { compressionLevel: 3, filters: canvas.PNG_FILTER_NONE }) // new
// or specify the mime type explicitly:
canvas.toBuffer('image/png', { compressionLevel: 3, filters: canvas.PNG_FILTER_NONE }) // new

// (4) #2 also applies for canvas.pngStream, although these arguments were not
//     documented:
canvas.pngStream(3, canvas.PNG_FILTER_NONE) // old
canvas.pngStream({ compressionLevel: 3, filters: canvas.PNG_FILTER_NONE }) // new

// (5) canvas.syncPNGStream() and canvas.syncJPEGStream() have been removed:
canvas.syncPNGStream() // old
canvas.createSyncPNGStream() // old
canvas.createPNGStream() // new

canvas.syncJPEGStream() // old
canvas.createSyncJPEGStream() // old
canvas.createJPEGStream() // new

// (6) Context2d.filter has been renamed to context2d.quality to avoid a
//     conflict with the new standard 'filter' property.
context.filter = 'best' // old
context.quality = 'best' // new

Breaking

Drop support for Node.js <6.x
Remove sync stream functions (bc53059). Note that most streams are still synchronous (run in the main thread); this change just removed syncPNGStream and syncJPEGStream.
Pango is now required on all platforms (7716ae4).
Make the quality argument for JPEG output go from 0 to 1 to match HTML spec.
Make the compressionLevel and filters arguments for canvas.toBuffer() named instead of positional. Same for canvas.pngStream(), although these arguments were not documented.
See also: Correct some of the globalCompositeOperator types under Fixed. These changes were bug-fixes, but will break existing code relying on the incorrect types.
Rename context2d.filter to context2d.quality to avoid a conflict with the new standard 'filter' property. Note that the standard 'filter' property is not yet implemented.

- "hsl-color" is now "color"
- "hsl-luminosity" is now "luminosity"
- "darker" is now "darken"
- "dest" is now "destination"
- "add" is removed (but is the same as "lighter")
- "source" is now "copy"

Merge pull request #507 from salzhrani/iojs
io.js compatibility
Merge pull request #505 from woodcoder/shadow-blur
Fix issue with line width not being correct in stroked shadows.
Add another shadow/transform test.
Refactor setSourceRGBA to allow the context to be supplied.
Simple image shadow (no blurring or handling current transforms) based on image's alpha channel.
Test showing issue #133, that images don't have shadows.
The +1 on the offset seems to match the browser's output better, but I can't work out why it would be needed (unless it's pixel alignment related).
Make the shadow radius more accurately match the browser's, making use of sigma scale as used in SKIA: https://github.com/google/skia/blob/master/src/effects/SkBlurMask.cpp#L26.
Create a new image surface to render blurred shadows to, this means that vector formats like PDF will now render blurs.

Add PDF button to test page to easily generate PDF version of the test image.
Fix to ensure shadowOffset is unaffected by the current transform.
New test illustrating that canvas implementation doesn't translate the shadowOffset.
Merge pull request #490 from AllYearbooks/master
Merge pull request #501 from motiz88/hsl-color
Code style + attribution. Also removed parseClipped() and commented out wrapInt (now wrap_int).
Added visual tests for hsl() and hsla() color parsing.
Fixed handling in hsl/hsla color parser. parseNumber() was erroring out on numbers with long fractional parts.
hsl/hsla color parsing + rebeccapurple hsl() and hsla() color values are now supported, with corresponding unit tests. Also added rebeccapurple (from CSS Color Level 4) to the named color list.
float rather than int for drawImage arguments
