Constructor & Destructor Documentation

KoPictureShared::KoPictureShared (  void   ) 
 

Default constructor.

Definition at line 39 of file KoPictureShared.cpp.

KoPictureShared::~KoPictureShared (  void   ) 
 

Destructor.

Definition at line 53 of file KoPictureShared.cpp.

KoPictureShared::KoPictureShared (  const KoPictureShared &  other  ) 
 

Copy constructor.

This makes a deep copy. Do not use if you want to share!

Definition at line 58 of file KoPictureShared.cpp.

Member Function Documentation

void KoPictureShared::clear (  void   ) 
 

Reset the KoPictureShared (but not the key!).

Definition at line 333 of file KoPictureShared.cpp.

void KoPictureShared::clearAndSetMode (  const QString &  newMode  ) 
 

Clear and set the mode of this KoPictureShared.

Parameters:
newMode file extension (like "png") giving the wanted mode

Definition at line 340 of file KoPictureShared.cpp.

void KoPictureShared::clearCache (  void   ) 
 

Clear any cache.

It is used to avoid using too much memory especially if the application somehow caches the KoPicture too.

Definition at line 504 of file KoPictureShared.cpp.

QDragObject * KoPictureShared::dragObject (  QWidget *  dragSource = 0L,
const char *  name = 0L
) 
 

Create a dragobject containing this picture.

Parameters:
dragSource must be 0 when copying to the clipboard
Returns:
0L if the picture is null!

Definition at line 470 of file KoPictureShared.cpp.

void KoPictureShared::draw (  QPainter &  painter,
int  x,
int  y,
int  width,
int  height,
int  sx = 0,
int  sy = 0,
int  sw = -1,
int  sh = -1,
bool  fastMode = false
) 
 

Draw the image in a painter.

The parameter fastMode allows the picture to be re-sized and drawn quicker if possible

The parameters width, height define the desired size for the picture

The other parameters are very similar to QPainter::drawPixmap : (x, y) define the position in the painter, (sx, sy) specify the top-left point in pixmap that is to be drawn. The default is (0, 0). (sw, sh) specify the size of the pixmap that is to be drawn. The default, (-1, -1), means all the way to the bottom right of the pixmap.

Definition at line 92 of file KoPictureShared.cpp.

QImage KoPictureShared::generateImage (  const QSize &  size  ) 
 

Generate a QImage.

(always in slow mode)

Parameters:
size the wanted size for the QImage

Definition at line 477 of file KoPictureShared.cpp.

QPixmap KoPictureShared::generatePixmap (  const QSize &  size,
bool  smoothScale = false
) 
 

Deprecated:
Returns a QPixmap from an image
Parameters:
size the wanted size for the QPixmap

Definition at line 463 of file KoPictureShared.cpp.

bool KoPictureShared::identifyAndLoad (  QByteArray  data  )  [protected]
 

Find type of image, create base accordingly, and load data.

Definition at line 154 of file KoPictureShared.cpp.

bool KoPictureShared::isNull (  void   )  const
 

Returns true if the picture is null.

Definition at line 85 of file KoPictureShared.cpp.

bool KoPictureShared::loadFromFile (  const QString &  fileName  ) 
 

Load a file.

Parameters:
fileName the name of the file to load

Definition at line 426 of file KoPictureShared.cpp.

bool KoPictureShared::loadXpm (  QIODevice *  io  ) 
 

Load a potentially broken XPM file (for KPresenter).

Definition at line 282 of file KoPictureShared.cpp.

KoPictureShared & KoPictureShared::operator= (  const KoPictureShared &  other  ) 
 

Assignment operator.

This makes a deep copy. Do not use if you want to share!

Definition at line 68 of file KoPictureShared.cpp.

bool KoPictureShared::save (  QIODevice *  io  )  const
 

Save picture into a QIODevice.

Parameters:
io QIODevice used for saving

Definition at line 317 of file KoPictureShared.cpp.

bool KoPictureShared::saveAsBase64 (  KoXmlWriter &  writer  )  const
 

OASIS FlatXML support: Save picture as base64-encoded data into an XML writer.
