Data.Text.ParagraphLayout

Description

Positions and distances are represented as 32-bit integers. Their unit must be defined by the caller, who must calculate the desired dimensions of the EM square of the input font and set them using optionScale.

For example, if 1em = 20px, if the output pixels are square, and if the output coordinates are in 1/64ths of a pixel, you should set the scale to Just (1280, 1280).

X coordinates increase from left to right.

Y coordinates increase from bottom to top.
