Detailed Description

This class manage the font library.

As a music notation program has a very particuliar way of usig font I choose to use my own font manager (Freetype)

Member Function Documentation

void FTFont::displayASCII (  uchar *  tab  )

This is an overloaded method provided for convinience

void FTFont::displayASCII (  FT_Bitmap  ft  )

Display the ASCII representation of a symbol

int FTFont::getFirstChar (   )

Returns: the first code of the font Deprecated:

QPoint FTFont::getFTOrg (  int  nglyph  )

Retrouve l'origine d'un point

int FTFont::getFTSize (   )

Returns: the size of the glyph

int FTFont::getGlyphEnc (  unsigned long  code, int  enc )

Returns: the glyph number expressed in a encoding Parameters: enc  the encoding used Todo: treat the parameter enc

QImage FTFont::getImage (  int  nglyph  )

Compute the render of a glyph *

QImage FTFont::getImageEnc (  unsigned long  code, int  enc )

Compute the rendering of a glyph in the current encoding Parameters: enc  the encoding used to compute the glyph changer la charmap. *

QImage FTFont::getImageTransformed (  int  nglyph, double  x00, double  x01, double  x10, double  x11 )

Returns: a glyph and transformed with the transform matrix x00,x01,x10,x11 Parameters: x00  x01  x10  x01  * destroy the image map. Later we will think about a hash not to destroy this beautiful work of allocation and rendering

int FTFont::getNextChar (  int  code  )

Returns: next character in font

QString FTFont::getPath (  QString  fontname  )

Returns: the path used for the font

uchar * FTFont::getUmap (  FT_Glyph  glyph  )

Compute the umap of a glyph Parameters: glyph  a glyph

uchar * FTFont::getUmap (  int  nglyph  )

/return the umap for building an image

FT_Bitmap FTFont::renderBmp (  FT_Glyph  glyph  )

Returns: a bitmap

FT_Bitmap FTFont::renderBmp (  int  nglyph  )

Returns: a FTBitmap.

void FTFont::setFTFontSize (  int  s  )

Warning this function is very tied to the set res fonction. Since they have the same effect. Every change ont the font size finally cause a change on the resolution. This could be wrong in the case of non proportionnal font. But I hope we never meet it in music notation.

void FTFont::setRez (  int  rx, int  ry )

set the resolution. We give the precedence to the resolution. So Parameters: rx  the x resolution ry  the y resolution

void FTFont::setRez (  int  r  )

This set the resX and resY to r this is porvide for convenience because in most case we are in isometric resolution Parameters: r  the isometric resolution

FT_Glyph FTFont::transformGlyph (  int  nglyph, double  x00, double  x01, double  x10, double  x11 )

Returns: a glyph and transformed with the transform matrix x00,x01,x10,x11 Parameters: x00  x01  x10  x01  *
