Member Function Documentation

alignLeft()

void al::Font::alignLeft ( )

inlineinherited

Returns the width of a text string, in pixels.

Returns the width of a character, in pixels Returns the "above-line" height of the font, in pixels Returns the "below-line" height of the font, in pixels Returns the total height of the font, in pixels Set alignment of rendered text strings

Parameters

[in]	xfrac	Fraction along text width to render at x=0; 0 is left-aligned, 0.5 is centered, 1 is right-aligned
[in]	yfrac	Fraction along text height to render at y=0

Definition at line 127 of file al_Font.hpp.

load()

bool al::Font::load ( const char *  filename, int  fontSize, int  bitmapSize  )

inherited

Load font from file

Parameters

[in]	filename	path to font file
[in]	fontSize	size of font
[in]	bitmapSize	size of font bitmap

Returns

whether font loaded successfully

write()

void al::Font::write ( Mesh &  mesh, const char *  text, float  worldHeight  )

inherited

Render text geometry Render text into geometry for drawing a string of text using the bitmap returned by ascii_chars. Render expects the vertex and texcoord buffers to be at least as big as the text length * 4 since each character is rendered by a quad.

Example usage:

    Mesh mesh;
    font.write(mesh, "allocore");

    font.texture().bind();
    g.draw(mesh);
    font.texture().unbind();
