Scrawl-canvas v8.6.1

New functionality:

• New vary-channels-by-weights filter - this replicates curveWeights functionality found in 3rd party software such as the Gimp
• Export the pseudo-random number generator from the scrawl object

Internal changes:

• Update demos by factoring out common code

Full Changelog: 8.6.0...v8.6.1

Scrawl-canvas v8.6.0

New functionality:

• Added functionality to allow canvas displays to take into account device screen dpr values, including automated changes when a user drags a browser window between screens with different dpr values. This new functionality is opt-in, to minimise breaking changes with existing SC-based canvas animations and displays. Note that this new functionality has been explicitly deactivated for Safari-based browsers

Full Changelog: 8.5.5...8.6.0

Scrawl-canvas v8.5.5

New functionality:

• New random noise filter
• New mapToGradient filter
• Added a Worley noise engine to the noise asset
• Crescent entity added

Improvements to:

• Investigated Lighthouse and made tweaks to the codebase to help improve Lighthouse score
• Noise asset can now display output using more complex gradients via the 'rainbow gradient' attributes

Non-breaking bug fixes for:

• Loom entity bugfix

Full Changelog: 8.5.4...8.5.5

Scrawl-canvas v8.5.4

New functionality:

• Added a new reaction-diffusion asset - to make RD-generated backgrounds accessible to SC Picture entitys and Pattern styles
• Added a 'stripe' engine to the noise asset

Improvements to:

• Rollup configuration tweaks

Full Changelog: 8.5.3...8.5.4

Scrawl-canvas v8.5.3

New functionality:

• Added a new gaussian blur filter - this is significantly faster than the existing blur filter and should be used in preference to the old approach
• Added a new raw asset - we can use this asset to make third party graphics library functionality accessible to SC Picture entitys and Pattern styles. Tested with: Delaunator (for Delaunay/Voronoi triangulation); Rapier physics engine (via WASM as Rapier is written in Rust); Tensorflow body-pix ML model; MediaPipe selfie-segmentation and face-mesh ML models
• Linespiral entity added

Full Changelog: 8.5.2...8.5.3

Scrawl-canvas v8.5.2

New functionality:

• Added a new corrode filter
• Support for conic gradients added

Improvements to:

• Work undertaken to make filters code faster

Internal changes:

• Entity stamp functionality reconsidered and rewritten

Non-breaking bug fixes for:

• Delta animation bugs fixed

Full Changelog: 8.5.1...8.5.2

Scrawl-canvas v8.5.1

Improvements to:

• Develop the 'snippet' concept - this work has been inspired by, but does not replicate, the approach to adding canvas effects and animations to DOM elements contained in the new Houdini Paint API

Internal changes:

• The 'component' concept has been renamed to 'snippet' - references to 'component' are deprecated

Non-breaking bug fixes for:

• Firefox pattern bug fixed

Full Changelog: 8.5.0...8.5.1

Scrawl-canvas v8.5.0

Internal changes:

• Filters - moved filters code from web worker back into main thread
• Removed web worker code - this simplifies the code base and makes SC easier to integrate with 3rd party tooling such as code bundlers
• As web workers have been removed, can also remove the Display cycle promises cascade

New functionality:

• Entity caching - this allows entitys with more intense filters applied to them to be rendered internally once, then have the cache image stamped on the display when required

Full Changelog: 8.4.0...8.5.0

Scrawl-canvas v8.4.0

Breaking changes to functionality:

• New filters system written from scratch - this new approach is inspired by the SVG filters approach where a filter effect can be built up using multiple paths
• The 'user-defined' filter has been deprecated and removed

New functionality:

• New filters include area-alpha, blend, channels-to-alpha, clamp-channels, colors-to-alpha, compose, displace, emboss, flood, offset, process-image
• Added a noise asset (to generate and use perlin, simplex noise)
• Mesh entity
• Make fonts measured in viewport units responsive to changes in the viewport dimensions

Improvements to:

• Easing functions

Non-breaking bug fixes for:

• Fixed a range of issues specific to the Safari browser
• Fixed a range of issues specific to the Firefox browser

Full Changelog: 8.3.4...8.4.0

Scrawl-canvas v8.3.4

New functionality:

• Added 'clearalpha' attribute to Cells - setting this to values >0 creates a ghosting effect on the display
• Track mouse movements over 3d rotated and scaled canvas elements

Non-breaking bug fixes for:

• Asset kill functionality
• Cell filter functionality

Full Changelog: 8.3.3...8.3.4
