Member Function Documentation

GlsFontBase* disti::DNCUtil::FontRenderer::GetFont ( void  )

inline

Get the font attached to the renderer

void DNCUtil::FontRenderer::InitRendering

(

void

)

Initializes the font to begin rendering characters. This will set up Open GL texture modes, bind the font's texture, set up minification and magnification filters, etc. This must be called before using any of the Render methods draw characters.

void DNCUtil::FontRenderer::RenderProportionalChar	(	const GlsFontBase::Char_t	c,
		const float	pen_position_x,
		const float	pen_position_y,
		const float	char_size_ratio_x,
		const float	char_size_ratio_y,
		const GLfloat	scale,
		const glsColor &	fgColor
	)

Render a single proportional character NOTE: assumes that a glBegin( GL_QUADS ) has been called

Parameters

c	character to render
pen_position_x	x position of lower left of character
pen_position_y	y position of lower left of character
char_size_ratio_x	x size ratio
char_size_ratio_y	y size ration
scale	character scale
fgColor	color for character

void DNCUtil::FontRenderer::TermRendering

(

void

)

Restores the Open GL state as it was before the call to InitRendering. This should be called after all characters have been rendered using the Render methods.
