Detailed Description

A class to split a pixmap into several items.

If you have a pixmap containing several items (icons), you can use this class to get the coordinates of each item.

For example, if you have a pixmap with 25 items and you want to get the 4th item as a pixmap (every item being 20x10 pixels): 

 KPixmapSplitter splitter;
 splitter.setPixmap( somePixmap );
 splitter.setItemSize( QSize( 20, 10 ));

 QPixmap item( 20, 10 );
 item.fill( Qt::white );
 QRect rect = splitter.coordinates( 4 );
 if ( !rect.isEmpty() )
     bitBlt( &item, QPoint(0,0), &somePixmap, rect, CopyROP );

Constructor & Destructor Documentation

KPixmapSplitter::KPixmapSplitter (    ) 
 

Constructor, does nothing but initializing some default-values.

Member Function Documentation

QRect KPixmapSplitter::coordinates (  const QChar &    ch ) 
 

Overloaded for convenience. Returns the item at the position of the given character (when using a latin1 font-pixmap)

QRect KPixmapSplitter::coordinates (  int    pos ) 
 

Returns:
the coordinates of the item at position pos in the given pixmap.

QSize KPixmapSplitter::itemSize (    )  const [inline]
 

Returns:
the set size of the items (coordinates) you want to get out of the given pixmap.

Definition at line 80 of file kpixmapsplitter.h.

const QPixmap& KPixmapSplitter::pixmap (    )  const [inline]
 

Returns:
the pixmap that has been set via setPixmap().

Definition at line 67 of file kpixmapsplitter.h.

void KPixmapSplitter::setHSpacing (  int    spacing ) 
 

If there is space between columns in the given pixmap, you have to specify how many pixels there are.

void KPixmapSplitter::setItemSize (  const QSize &    size ) 
 

Sets the size of the items you want to get out of the given pixmap. The QRect of coordinates(int) will have the width and height of exactly this size.

void KPixmapSplitter::setPixmap (  const QPixmap &    pixmap ) 
 

Sets the pixmap to be splitted.

void KPixmapSplitter::setVSpacing (  int    spacing ) 
 

If there is space between rows in the given pixmap, you have to specify how many pixels there are.
