Version 0.19.8

Changes

• Line segments with zero width or zero opacity won't be found by pointSearch or polygonSearch (#1041)

Bug Fixes

• Removed extra calls to sceneObject constructors (#1039)
• Fixed an issue with rendering on hidden tabs in Chrome (#1042)

Version 0.19.7

Features

• The osmLayer now has predefined tileSources that can be used with the source method or property to switch multiple parameters at once (#1020)

Improvements

• Points with small radii or thin strokes are rendered better (#1021)
• When only updating point styles, don't recompute geometry transforms (#1022)
• Optimized a transform code path for pixel coordinates (#1023)
• WebGL point features automatically use the most memory-efficient primitive shape for the point sizes used based on the system's graphics capabilities (#1031)
• Less data is transfered to the GPU when only styles have changed in webgl line or polygon features (#1016)

Changes

• Switched the default tile server to Stamen Design's toner-lite (#1020)

Bug Fixes

• Mouse wheel events didn't recompute gcs coordinates, so a wheel event without a previous move event coult list the wrong location (#1027)
• Original event data was not included with actionwheel events (#1030)

Version 0.19.6

Features

• Added a polygonSearch method to features (#1014)

Changes

• The feature boxSearch function now uses map input gcs coordinates consistently and returns results in the same format as pointSearch (#1014)
• The pointTo2DTriangleBasis utility function was renamed to pointToTriangleBasis2d (#1014)

Version 0.19.5

Features

• Fetch queues can have an initial size different from their regular size (#1000)
• Autoshare renderers now has three states, with the default being more likely to not change anything visually (#1011)

Improvements

• More response zooming via mouse wheel (#993)
• Explicitly exit retired renderers when autosharing renderers (#1007)
• If a point has no stroke or fill, don't return it from pointSearch (#1003)
• WebGL point, line, polygon, and contour features use a localized origin for improved precision at high zoom levels. This reduces panning jitter in zoom levels 19 and up (#1005)
• When doing a point search on a line feature, report which line segment is found (#1008)
• Include source event information in some feature events (#1009)

Changes

• Idle handlers no longer defer to scene-graph parents. Parents still wait for all children to be idle (#1001)
• Better handling of tiles with overlap (#997)

Bug Fixes

• Shared tile layers stack properly by clearing quads on layer addition and removal (#1010)

Version 0.19.4

Improvements

• Speed up rebuilding webgl point features (#994)

Version 0.19.3

Features

• Layers that use webgl renderers automatically share contexts when possible. Layers can switch renderers manually as well. This largely avoids the limitation of number of webgl contexts in a browser (#975)
• Support affine transforms in the proj4 string (#986)

Improvements

• Speed up rendering geojson features by using constant values for constant geojson styles (#987)

Changes

• The point clustering radius value is now in display pixels (#983)

Bug Fixes

• Fixed drawing partial fixed-scale canvas quads (#985)

Version 0.19.2

Version 0.19.2

Improvements

• Make fewer function calls when computing polygon strokes (#980)
• Speed up coordinate transforms that only switch y-axis (#979)

Version 0.19.1

Features

• Polygon annotations can be drawn in the same continuous smooth manner as line annotations (#976)

Changes

• Rename the d3 renderer to svg. d3 still works as an alias (#965)
• Rename the vgl renderer to webgl. vgl still works as an alias (#965)

Version 0.19.0

Features

• Feature selection API is now enabled automatically if any event handlers are bounds to the feature (#921)
• Added a VTK.js renderer which supports a point feature (#893, #953)

Improvements

• Coordinate transforms on flat arrays are now faster (#939)
• convertColor is memoized to speed up repeated calls (#936)
• All features have a featureType property (#931)
• When changing geometry sizes, buffers are reallocated less (#941)
• Initial rendering webGL features is somewhat faster (#943)
• WebGL point and polygon features no longer clip by z coordinates (#963)

Changes

• Removed the dependency on the vgl module for the object and timestamp classes (#918)
• CSS color names are obtained from an npm package rather than being defined in the util module (#936)
• Updated several npm modules (#944)
• Report the unmasked renderer used with webgl (#947)
• Width and height are now in the base renderer class (#962)

Bug Fixes

• Fixed some minor issues with layers (#949)

Documentation

• Improve documentation (#922, #928, #929, #930, #932, #948, #950, #951, #956, #960, #961)
• Added a point cluster example (#957)
• Editor tutorials keep history in browser (#926)

Version 0.18.1

Bug Fixes

• Fixed an issue with the annotation key handler (#923)
