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: file   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.

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.

Member Function Documentation

GLfloat OGLFT::Raster::characterRotationZ ( void ) const [inline, virtual]

Returns: the character rotation in the Z direction. Reimplemented from OGLFT::Face.

double OGLFT::Raster::height ( void ) const [virtual]

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

BBox OGLFT::Raster::measure ( const QString & format, double number ) [inline, virtual]

Implement measuring a formatted number Parameters: format   the format string number   to value to format Returns: the bounding box of the formatted number Reimplemented from OGLFT::Face.

BBox OGLFT::Raster::measure ( const char * s ) [inline, virtual]

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.

BBox OGLFT::Raster::measure ( const QChar c ) [virtual]

Implement measuring a character in a raster face. Parameters: c   the (UNICODE) character to measure Returns: the bounding box of c. Reimplemented from OGLFT::Face.

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. Reimplemented from OGLFT::Face.

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. Reimplemented from OGLFT::Face.
