Pdok 18835/vervanging trex v2 tile detection

[DvBree]

Description

Added options to texel for detecting which tiles a geometry lies on, including option with buffer. Two mechanisms for detecting tiles have been added: BBox, using the bbox of the polygon in question, and LineTrace, tracing the edge of the polygon and finding tiles on the inside. Tiles on the inside are encoded by a default precomputed tile-filling square.

Changes to interface:

• Added tilebuffer (buf) as flag, in internal pixel size. Default 0.
• Added uselinetrace (lt) as flag. true means using linetrace, false means using bbox for tile detection. Default false.

Both flags are only relevant if encoding is enabled.

Type of change

• New feature
