struct Font

A bitmap font: every character is a cell of the same size. The two built-in fonts are the “fixed” fonts of X11, with ASCII, Latin-1 and a few typographic marks and arrows; other characters are drawn as ?. Zoom draws every pixel of a glyph as a square of that many pixels.

Fields

Name	Description
Width	The width of a character cell in pixels (without the zoom).
Height	The height of a character cell in pixels (without the zoom).
Ascent	How far the baseline is below the top of a cell.
Zoom	Every font pixel becomes Zoom x Zoom pixels.

Width

int Width

The width of a character cell in pixels (without the zoom).

Height

int Height

The height of a character cell in pixels (without the zoom).

Ascent

int Ascent

How far the baseline is below the top of a cell.

Zoom

int Zoom

Every font pixel becomes Zoom x Zoom pixels.

Static methods

Name	Description
Fixed7x13	7 x 13 pixels: for a scale of 1 (96 dpi).
Fixed10x20	10 x 20 pixels: for a scale of about 1.5.
ForScale	The built-in font that suits a scale (1 = 96 dpi): 7x13, 10x20, and both zoomed for higher scales.
Metrics	A font of which only the sizes are known: for a Ui that is drawn with commands (Ui.BeginCommands) by a renderer with its own font (AmigaOS: the system font).

Fixed7x13

static Font Fixed7x13()

7 x 13 pixels: for a scale of 1 (96 dpi).

Fixed10x20

static Font Fixed10x20()

10 x 20 pixels: for a scale of about 1.5.

ForScale

static Font ForScale(double scale)

The built-in font that suits a scale (1 = 96 dpi): 7x13, 10x20, and both zoomed for higher scales.

Metrics

static Font Metrics(int width, int height, int ascent)

A font of which only the sizes are known: for a Ui that is drawn with commands (Ui.BeginCommands) by a renderer with its own font (AmigaOS: the system font). It draws nothing itself.
