vector_tile_renderer 2.5.0

A vector tile renderer for use in creating map tile images or writing to a canvas.

2.5.0

• improve preprocessing capability so that additional preprocessing can be separated from drawing
• more optimizations

2.4.7

• fix bug that prevented some themes from working with an exception "Cannot get paths from a point feature"

2.4.6

• add minimal support for fill-extrusion polygons by rendering a polygon without extrusion

2.4.5

• enable caching and incremental instantiation of TextPainter, see TextPainterProvider for details

2.4.3

• improved performance with expression short-circuit for constant expressions

2.4.2

• improved performance with expression caching

2.4.1

• add support for line-cap and line-join layout

2.4.0

• text halo color can now use expressions
• add support for text-justify and text-max-width
• bug fix to theme filters that reference zoom level
• breaking API change, TilesetPreprocessor now requires a zoom level

2.3.3

• improve support for color expressions
• add support for case expressions
• support let and var expressions
• add support for cubic-bezier interpolation

2.3.2

• added support for more theme expressions: math, coalesce, step
• theme background color and text anchor can now use expressions

2.3.1

• performance improvements
• support for geometry-type expression

2.3.0

• performance improvements

Thanks to Gabriel Terwesten for their contributions.

2.2.8

• add theme copy function

2.2.7

• reduce memory overhead by filtering tile data with the theme

2.1.6

• make tileset compatible with passing between isolates

2.1.5

• improve support for theme expressions
• improve support for linear/exponential interpolation
• improve label placement to have fewer unlabelled roads
• improve efficiency of rendering by moving more calculations into the TilesetPreprocessor
• improve efficiency of rendering with a change to the vector_tile dependency

2.1.4

• reduce CPU overhead of text rendering

2.1.3

• introduce tileset preprocessing to reduce CPU overhead while rendering

2.0.2

• reduced memory overhead when rendering to a Canvas that is scaled and clipped
• reduced CPU overhead of text labels

2.0.0

• support multiple source tiles so that it's possible to have multiple data sources, for exmaple when rendering hillshade

1.0.7

• only abbreviate place names that appear at the end of text

1.0.6

• add theme versioning

1.0.4

• add abbreviations for place names

1.0.3

0.1.10

• avoid label collisions by eliminating labels that would draw over others
• rotate labels to align with roads

0.1.9

• improve performance
• improve line size interpolation
• introduce zoomScaleFactor for rendering tiles at greater than their normal size

0.1.7
