virtual int cFont::Width ( uint  c  )  const [pure virtual]

virtual int cFont::Width ( const char *  s  )  const [pure virtual]

Returns the width of the given string in pixel.

Implemented in cFreetypeFont, cDummyFont, and cCursesFont.

virtual int cFont::Height ( void   )  const [pure virtual]

int cFont::Height ( const char *  s  )  const [inline]

Returns the height of this font in pixel (obsolete, just for backwards compatibilty).

virtual void cFont::DrawText ( cBitmap Bitmap,
int  x,
int  y,
const char *  s,
tColor  ColorFg,
tColor  ColorBg,
int  Width 
) const [pure virtual]

Draws the given text into the Bitmap at position (x, y) with the given colors. The text will not exceed the given Width (if > 0), and will end with a complete character.

Implemented in cFreetypeFont, cDummyFont, and cCursesFont.

Referenced by cBitmap::DrawText().

void cFont::SetFont ( eDvbFont  Font,
const char *  Name,
int  CharHeight 
) [static]

Sets the given Font to use the font data according to Name (see CreateFont()) and make its characters CharHeight pixels high.

Here is the call graph for this function:

const cFont * cFont::GetFont ( eDvbFont  Font  )  [static]

Gets the given Font, which was previously set by a call to SetFont(). If no SetFont() call has been made, the font as defined in the setup is returned. The caller must not use the returned font outside the scope in which it was retrieved by the call to GetFont(), because a call to SetFont() may delete an existing font.

Here is the call graph for this function:

cFont * cFont::CreateFont ( const char *  Name,
int  CharHeight,
int  CharWidth = 0 
) [static]

Creates a new font object with the given Name and makes its characters CharHeight pixels high. If CharWidth is given, it overwrites the font's default width. Name is of the form "Family:Style", for instance "Verdana:Bold Italic" or "Times New Roman". See GetAvailableFontNames() for how to get a list of all available font names. If the requested font can't be created, NULL is returned. The caller must delete the font when it is no longer needed.

Here is the call graph for this function:

bool cFont::GetAvailableFontNames ( cStringList FontNames,
bool  Monospaced = false 
) [static]

Queries the font configuration for a list of available font names, which is returned in FontNames. If Monospaced is true, only monospaced fonts will be returned. The resulting font names are in a format that can be used with GetFontFileName() to get the name of the actual font file. Returns true if any font names were found.
