Expand description

A structure containing graphical parameters

This is how graphical parameters are passed from graphics systems to the graphics engine AND from the graphics engine to graphics devices.

Devices are not required to honour graphical parameters (e.g., alpha transparency is going to be tough for some)

Fields§

§col: c_int

pen colour (lines, text, borders, …)

§fill: c_int

fill colour (for polygons, circles, rects, …)

§gamma: f64

Gamma correction

§lwd: f64

Line width (roughly number of pixels)

§lty: c_int

Line type (solid, dashed, dotted, …)

§lend: R_GE_lineend

Line end

§ljoin: R_GE_linejoin

line join

§lmitre: f64

line mitre

§cex: f64

Character expansion (font size = fontsize*cex)

§ps: f64

Font size in points

§lineheight: f64

Line height (multiply by font size)

§fontface: c_int

Font face (plain, italic, bold, …)

§fontfamily: [c_char; 201]

Font family

§patternFill: SEXP

Reference to a pattern fill
