Detailed Description

This is the painter for a printer. Be very carefull with the use of the begin and end method. You can only call begin() and end() this is different from screen painter for example. And after you should send the print to the spooler. This class generate big files and some instruction given era not necessary, there could be a little optimisation if only the necessary instruction were given for exemple it is not necessary to call find font when the font does not change

Constructor & Destructor Documentation

Printer::Printer (  int  pages  )

This is the default constructor of a printer

Member Function Documentation

void Printer::addFont (  QString  filename  )

Cette méthode ajoute la fonte elle est a appeler juste après l'entête. L'ajout se fait immédiatement après l'écriture de l'entête

void Printer::addResource (  QString  filename  )

This method add encoding resource. I did not understtand really what it does, I just did a copyPaste

void Printer::begin (   )  [virtual]

This method writes the header of the file ps genrated by the ps file Parameters: pages  The number of pages to be printed (So it has to be computed before the printing Implements Painter.

void Printer::drawBrace (  double  x, double  y1, double  y2 )  [virtual]

This draws a brace on the printer Parameters: x  y1  y2  Implements Painter.

void Printer::drawEllipse (  float  , float  , float  , float  )  [virtual]

The draw ellipse is not yet implemented on the printer Implements Painter.

void Printer::drawFontGlyph (  float  bx, float  by, int  glyph, QString  font )

Warning : Postscript uses an octal representation of characters

void Printer::drawFTSymbol (  int  glyph, float  bx, float  by )  [virtual]

Draws a freetype symbol Implements Painter.

void Printer::drawLine (  double  , double  , double  , double  )  [virtual]

draws the line {(x1,y1),(x2,y2)} Implements Painter.

void Printer::drawNoteLine (  float  , float  , int  )  [virtual]

Deprecated: use draw line instead Implements Painter.

void Printer::drawRect (  double  , double  , double  , double  )  [virtual]

draws a rect {(x1,y1),(x2,y2)} Implements Painter.

void Printer::drawSlur (  double  , double  , double  , double  , int  )  [virtual]

draws the brace tying {(x1,y1),(x2,y2)} of direction d Implements Painter.

void Printer::drawStemBar (  double  , double  , double  , double  )  [virtual]

draws the stem bar {(x1,y1),(x2,y2)} Implements Painter.

void Printer::drawText (  double  bx, double  by, QString  text )  [virtual]

This draws some text. Warning : There is still some concern with the encoding, for instance : ’ cannot be drawn, you should use ' instead. Idont understand why the scale is not corresponding to the real fontSize. So I divide by 2, but it should be fixed in the long run. Implements Painter.

void Printer::end (   )  [virtual]

End the printing, various settings like the page size remains to be implemented. This is only at this stage that the printing is done Implements Painter.

QCoordsRect Printer::getBoundingBox (  int  nglyph  )  [virtual]

Not implemented Implements Painter.

bool Printer::isPrinter (   )  [virtual]

Returns: true (Of course !) Reimplemented from Painter.

void Printer::newPage (   )  [virtual]

Draws a new page Reimplemented from Painter.

void Printer::print (   )

Cette méthode imprime dans le fichier

void Printer::setBrush (  const QColor &  col  )  [virtual]

The color is not yet implemented on the printer Implements Painter.

void Printer::setBrush (  Qt::BrushStyle   )  [virtual]

set PenColor has the same role that setPen we should remove it Implements Painter.

void Printer::setFont (  QFont   )  [virtual]

This set the font Implements Painter.

void Printer::setFontFamily (  int   )  [virtual]

Function relative to text Implements Painter.

void Printer::setFontSize (  double  f  )  [virtual]

Donne sa taille à la fonte couramment utilisée Implements Painter.

void Printer::setFTFont (  int   )  [virtual]

Function related to the musicaldont Implements Painter.

void Printer::setFTSize (  int   )  [virtual]

Methods related to the Freetype Font Implements Painter.

void Printer::setPen (  Qt::PenStyle   )  [virtual]

The setPen is not yet implemented on the printer Implements Painter.

void Printer::setPen (  const QColor &   )  [virtual]

sets the pen color Implements Painter.

void Printer::setPenColor (  const QColor &   )  [virtual]

Deprecated: set PenColor has the same role that setPen we should remove it Implements Painter.

void Printer::setTextAlign (  int  i  )  [virtual]

Set the text alignement. This is maybe unecessary to duplicate this function in all the chlidren of Painter. Implements Painter.
