## Public Member Functions
| KPixmapSplitter ()
| Constructor, does nothing but initializing some default-values.
void | setPixmap (const QPixmap &pixmap)
| Sets the pixmap to be splitted.
const QPixmap & | pixmap () const
void | setItemSize (const QSize &size)
| Sets the size of the items you want to get out of the given pixmap.
QSize | itemSize () const
void | setVSpacing (int spacing)
| If there is space between rows in the given pixmap, you have to specify how many pixels there are.
void | setHSpacing (int spacing)
| If there is space between columns in the given pixmap, you have to specify how many pixels there are.

## Detailed Description

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

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 );

KPixmapSplitter::KPixmapSplitter | ( |  | ) |

| Constructor, does nothing but initializing some default-values. Definition at line 22 of file kpixmapsplitter.cpp.

## Member Function Documentation

void KPixmapSplitter::setPixmap | ( | const QPixmap & | pixmap | ) |

| Sets the pixmap to be splitted. Definition at line 36 of file kpixmapsplitter.cpp.

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::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`. Definition at line 42 of file kpixmapsplitter.cpp.

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.

void KPixmapSplitter::setVSpacing | ( | int | spacing | ) |

| If there is space between rows in the given pixmap, you have to specify how many pixels there are. Definition at line 50 of file kpixmapsplitter.cpp.

void KPixmapSplitter::setHSpacing | ( | int | spacing | ) |

| If there is space between columns in the given pixmap, you have to specify how many pixels there are. Definition at line 58 of file kpixmapsplitter.cpp.

QRect KPixmapSplitter::coordinates | ( | int | pos | ) |

| Returns: the coordinates of the item at position pos in the given pixmap. Definition at line 67 of file kpixmapsplitter.cpp. References QSize::height(), QPixmap::height(), QPixmap::isNull(), QSize::width(), and QPixmap::width(). Referenced by coordinates().

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) Definition at line 91 of file kpixmapsplitter.cpp. References coordinates(), and QChar::latin1().
