Std.Ui.Text.draw

1 declaration

fn

draw: &Std.Ui.Text.Face -> &Std.Ui.Canvas.Canvas -> Std.Ui.Canvas.Point -> Str -> Std.Ui.Canvas.Color -> Result[Std.Ui.Canvas.Canvas, Std.Ui.Text.TextError]

This is a callable function.

What it does

A canvas with text drawn from an origin at the top left of its first line.

Each glyph becomes the fewest rectangles its bitmap allows: lit columns in

a row join into one run, and a run repeated in the rows below it joins into

one taller rectangle, so a stem is one command rather than seven.

Read the signature

  • The text after the name is the type checked by Pudu.
  • Read arrows from left to right: inputs come first, and the final type is returned.
  • & borrows a value for this call instead of moving or copying it.
  • Names inside [ ] are type arguments, such as the item type held by a collection.
  • Result makes success and recoverable failure part of the function's type.
