Typeface

Low-level interface for drawing text. Represents a single typeface.

Unlike the rest of Fluid, Typeface doesn't define pixels as 1/96th of an inch. DPI must also be specified manually.

See: fluid.text.Text for an interface on a higher level.

Functions

advance Vector2 advance(dchar glyph): Get advance vector for the given glyph. Uses dots, not pixels, as the unit.
defaultWordChunks defaultWordChunks(Range range): Default word splitter used by measure/draw.
dpi Vector2 dpi(Vector2 scale): Set font scale. This should be called at least once before drawing.
dpi Vector2 dpi(): Get curently set DPI.
draw void draw(Image image, Rectangle rectangle, String text, Color tint, bool wrap): Draw text within the given rectangle in the image.
drawLine void drawLine(Image target, Vector2 penPosition, string text, Color tint): Draw a line of text. Note: This API is unstable and might change over time.
glyphCount long glyphCount(): List glyphs in the typeface.
lineHeight int lineHeight(): Get line height.
measure Vector2 measure(Vector2 availableSpace, String text, bool wrap)
Vector2 measure(String text): Measure space the given text would span. Uses dots as the unit.
penPosition Vector2 penPosition(): Get initial pen position.

Static functions

defaultTypeface defaultTypeface(): Get the default Fluid typeface.
