rasterise: rasterise tiles

In patrickCNMartin/Vesalius: Vesalius: Dissecting Tissue Anatomy from Spatial Transcriptomic Data

rasterise tiles

Description

fill tiles with pixel - rasterisation

Usage

rasterise(filtered)

Arguments

filtered

data.frame with voronoi tile coordinates

Details

Here, we take our tile cooridnates and fill them with pixels. Essentially, each voronoi tile can be discretised into a series of pixels and we achieve this by reconstructing a polygon from the tesselation coordinates and finding all discrete value that fall within this polygon.

Note that the polygon coordinates need to be "convexified". Essentially, the order of the coordinates maters here so we order the coordinates before recontructing the polygon (see convexify)

Value

a data frame barcodes and their associated pixels.
