Detailed Description

This is the base class of the raster styles: bitmap, grayscale and translucent.

In the raster styles, FreeType's rasterizer is used to generate raster images of each glyph.

Constructor & Destructor Documentation

OGLFT::Raster::Raster	(	const char *	filename,
		float	point_size = `12`,
		FT_UInt	resolution = `100`
	)

Parameters

filename	the filename which contains the font face.
point_size	the initial point size of the font to generate. A point is essentially 1/72th of an inch. Defaults to 12.
resolution	the pixel density of the display in dots per inch (DPI). Defaults to 100 DPI.

Definition at line 1317 of file moOGLFT.cpp.

OGLFT::Raster::Raster	(	FT_Face	face,
		float	point_size = `12`,
		FT_UInt	resolution = `100`
	)

Parameters

face	open FreeType FT_Face.
point_size	the initial point size of the font to generate. A point is essentially 1/72th of an inch. Defaults to 12.
resolution	the pixel density of the display in dots per inch (DPI). Defaults to 100 DPI.

OGLFT::Raster::~Raster ( void )

virtual

The destructor doesn't do anything in particular.

Definition at line 1340 of file moOGLFT.cpp.

Member Function Documentation

GLfloat OGLFT::Raster::characterRotationZ ( void ) const

inlinevirtual

Returns: the character rotation in the Z direction.

Implements OGLFT::Face.

Definition at line 1735 of file moOGLFT.h.

double OGLFT::Raster::height ( void ) const

virtual

Returns: the height (i.e., line spacing) at the current character size.

Implements OGLFT::Face.

Definition at line 1354 of file moOGLFT.cpp.

BBox OGLFT::Raster::measure ( unsigned char c )

virtual

Implement measuring a character in a raster face.

Parameters

c	the (latin1) character to measure

Returns: the bounding box of c.

Implements OGLFT::Face.

Definition at line 1362 of file moOGLFT.cpp.

BBox OGLFT::Raster::measure ( const char * s )

inlinevirtual

Measure a string of characters. Note: currently, this merely calls Face's measure routine.

Parameters

s	string of (latin1) characters to measure

Returns: the bounding box of s.

Reimplemented from OGLFT::Face.

Definition at line 1765 of file moOGLFT.h.

void OGLFT::Raster::setCharacterRotationZ ( GLfloat character_rotation_z )

virtual

Set the individual character rotation in the Z direction.

Parameters

character_rotation_z angle in degrees of Z rotation.

Implements OGLFT::Face.

Definition at line 1345 of file moOGLFT.cpp.

Member Data Documentation

GLfloat OGLFT::Raster::character_rotation_z_

protected

Raster glyph can be rotated in the Z plane (in addition to the string rotation).
