iTextHeight	is the desired text height in pixels.
strText	is the text to be drawn onto the screen.
fnt	is the font to be used for rendering the text.
iAlignFlags	sets how the text may be aligned.

		string	strText,
		font_s	fnt
	)

Right-aligned variant of Font_DrawText.

		float	a,
		font_s	fnt
	)

		string	strText,
		vector	col,
		font_s	fnt
	)

		string	strText,
		vector	col,
		float	a,
		font_s	fnt
	)

Right-aligned variant of Font_DrawText_RGBA.

See also: Font_DrawText_RGBA

◆ Font_DrawText()

void Font_DrawText	(	vector	vecOrigin,
		string	strText,
		font_s	fnt
	)

Draw text on the screen at the desired position with a desired font.

Parameters

vecOrigin	is the absolute starting position.
strText	is the text to be drawn.
fnt	is the font to be used.

◆ Font_DrawText_A()

void Font_DrawText_A	(	vector	vecOrigin,
		string	strText,
		float	a,
		font_s	fnt
	)

Draw alpha-blended text on the screen at the desired position with a desired font.

Parameters

vecOrigin	is the absolute starting position.
strText	is the text to be drawn.
a	is the alpha value to blend with.
fnt	is the font to be used.

◆ Font_DrawText_RGB()

void Font_DrawText_RGB	(	vector	vecOrigin,
		string	strText,
		vector	col,
		font_s	fnt
	)

Draw tinted text on the screen at the desired position with a desired font.

Parameters

vecOrigin	is the absolute starting position.
strText	is the text to be drawn.
col	is the normalized color value to tint the text with.
fnt	is the font to be used.

◆ Font_DrawText_RGBA()

void Font_DrawText_RGBA	(	vector	vecOrigin,
		string	strText,
		vector	col,
		float	a,
		font_s	fnt
	)

Draw tinted and alpha blended text on the screen at the desired position with a desired font.

Parameters

vecOrigin	is the absolute starting position.
strText	is the text to be drawn.
col	is the normalized color value to tint the text with.
a	is the alpha value to blend with.
fnt	is the font to be used.

◆ Font_GetHeight()

int Font_GetHeight ( font_s fnt )

Returns the height of a specified font in pixels.

Parameters

fnt	is the font to be queried.

Returns: is the height of a font in pixels.

See also: Font_StringWidth

◆ Font_GetID()

float Font_GetID ( font_s fnt )

Get the internal font id.

The internal font id is only useful for when you want to assign 'drawfont' yourself, or have some other use for it. Those id's are meant to be unique, but may change between vid_reload or other cases where video memory is de-allocated. Overall you should never need to use this, unless you know what you're doing or are porting old code.

Parameters

fnt	is the font to be queried.

Returns: the internal 'drawfont' id of the specified font.

◆ Font_Load()

void Font_Load	(	string	strFile,
		font_s &	fntNew
	)

Load a desired .font definition into memory.

Parameters

strFile	is the path to the file in question.
fntNew	is the location of where the font will be stored.

◆ Font_RGBtoHex()

string Font_RGBtoHex ( vector vecColor )

Converts a normalized RGB color vector to a hex color string.

Parameters

vecColor is the normalized input color. E.g. [1.0f, 0.0f, 0.0f]

Returns: is a hex color string. e.g. "^xF00"

◆ Font_StringWidth()

float Font_StringWidth	(	string	strText,
		bool	hasColor,
		font_s	fnt
	)

Returns the width of a series of characters in pixels.

If you have a string with funstring color codes (e.g. ^1 or ^xF00) and want to make sure those are not interpreted as visible characters, set the parameter hasColor to true. Rendering may be more expensive this way, but you should generally cache the result instead of querying it every frame anyway.

The return value is of type float, to be a drop-in replacement for the engine builtin stringwidth().

Parameters

strText	is the text to get the length of.
hasColor	hints if funstring color codes are present in the string.
fnt	is the font used with the text in question.
