scatter_lines_histogram

Description

Render lines into a histogram.

Usage

scatter_lines_histogram(
  xy,
  xlim = c(min(xy[, c(1, 3)]), max(xy[, c(1, 3)])),
  ylim = c(min(xy[, c(2, 4)]), max(xy[, c(2, 4)])),
  out_size = c(512L, 512L),
  skip_start_pixel = FALSE,
  skip_end_pixel = TRUE
)

Arguments

xy	4-column matrix with point coordinates. Each row contains X and Y coordinates of line start and X and Y coordinates of line end, in this order.
xlim, ylim	2-element vector of rendered area limits (position of the first pixel on the left/top, and the last pixel on the right/bottom). You can flip the image coordinate system by flipping the ⁠*lim⁠ vectors.
out_size	2-element vector size of the result raster, defaults to c(512L,512L).
skip_start_pixel	TRUE if the start pixel of the lines should be omitted, defaults to FALSE.
skip_end_pixel	TRUE if the end pixel of a line should be omitted, defaults to TRUE. (When plotting long ribbons of connected lines, this prevents counting the connecting pixels twice.)

Value

Histogram with the rendered lines.
