Member Function Documentation

ILubyte FontManager::getPixelAlpha	(	const ILuint &	x,
		const ILuint &	y
	)			[private]

Gets a pixel's alpha value from the active DevIL image (top left origin).

Returns the grayscale value of the active grayscale image at the coordinates x and y with the origin in the top left corner.

Parameters:

	x	The x coordinate
	y	The y coordinate

Returns:

The color of the selected pixel ranging 0..255

void FontManager::getMinMax	(	const unsigned char &	charId,
		Uint32 &	min,
		Uint32 &	max
	)			[private]

Gets the left and right border of a character in the active DevIL image.

calculates the coordinates of the right quad

Parameters:

	charId	The Id (0..255) of the Character whose position is wanted
	charXmin	The minimal x Coordinate of the character
	charYmax	The minimal y coordinate of the character

void FontManager::generateFontCoords	(	Texture &	texture,
		struct fontCoords *	coords
	)			[private]

Generates a font coordinates set from a texture.

FontManager * FontManager::getInstance

(

)

[static]

The getter for the singleton instance.

The only way to access the manager

void FontManager::registerFont	(	const string &	fontname,
		const string &	filename,
		const string &	filenameBold
	)

Registers a font for use in the Font Manager.

Adds a font if not already present.

Parameters:

	fontname	The identifier for this font. Must be unique, otherwise this call has no effect.
	filename	The path to the standard styled texture of that font
	filename	The path to the bold styled texture of that font

void FontManager::bindStandard

(

const string &

fontname

)

Binds the standard texture of a font in OpenGL.

Makes the font's standard texture the active texture to use in OpenGL.

Parameters:

filename

Must be a fontname already registered otherwise the call will have no effect.

void FontManager::bindBold

(

const string &

fontname

)

Binds the bold texture of a font in OpenGL.

Makes the font's standard texture the active texture to use in OpenGL.

Parameters:

filename

Must be a fontname already registered otherwise the call will have no effect.

Texture * FontManager::getStandardTexture

(

const string &

fontname

)

Returns the standard texture of a font.

Parameters:

fontname

Must be a fontname already registered otherwise the call returns 0. This returns the standard styled font texture.

Returns:

The texture that is assigned to this font. 0 indicates an error.

Texture * FontManager::getBoldTexture

(

const string &

fontname

)

Returns the bold texture of a font.

Parameters:

fontname

Must be a fontname already registered otherwise the call returns 0. This returns the bold styled font texture.

Returns:

The texture that is assigned to this font. 0 indicates an error.

struct fontCoords * FontManager::getStandardCoords

(

const string &

fontname

)

[read]

Returns the coordinate sets of the standard styled texture of a font.

struct fontCoords * FontManager::getBoldCoords

(

const string &

fontname

)

[read]

Returns the coordinate sets of the bold styled texture of a font.

string FontManager::toString

(

)

const [virtual]

Returns a textual representation.

Returns:

a string descriping the run-time object

string FontManager::className

(

)

const [virtual]

Returns the class name of the object.

Returns:

a string with the name of the object's class

enum classId FontManager::classId

(

)

const [virtual]

Returns the class id of the object.

Returns:

an id of the object's class
