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.

• Fix formatting of color strings (e.g. ctx.fillStyle) on 32-bit platforms
• Explicitly export symbols for the C++ API
• Named CSS colors should match case-insensitive
• Correct some of the globalCompositeOperator types to match the spec:
  • "hsl-hue" is now "hue"
  • "hsl-saturation" is now "saturation"
  • "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"
