Detailed Description

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 );

 @short A class to split a pixmap into several items.

Constructor, does nothing but initializing some default-values.

Set the pixmap to be splitted.

[const]

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

Set the size of the items you want to get out of the given pixmap. The QRect of coordinate will have the width and height of exactly this size.

[const]

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

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

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

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

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