Member Function Documentation

QDragObject * KoPictureBase::dragObject (  QWidget *  dragSource = 0L,
const char *  name = 0L
)  [virtual]
 

Create a dragobject containing this picture.

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

Reimplemented in KoPictureImage.

Definition at line 125 of file KoPictureBase.cpp.

void KoPictureBase::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
)  [virtual]
 

Draw the picture 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 image Note that the image is being scaled to that size using scale() - except when printing. This avoids scaling the image at each paint event.

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.

Reimplemented in KoPictureClipart, KoPictureEps, KoPictureImage, and KoPictureWmf.

Definition at line 67 of file KoPictureBase.cpp.

QImage KoPictureBase::generateImage (  const QSize &  size  )  [virtual]
 

Generate a QImage (always in slow mode).

Reimplemented in KoPictureEps, and KoPictureImage.

Definition at line 134 of file KoPictureBase.cpp.

bool KoPictureBase::isNull (  void   )  const [virtual]
 

Returns true if the picture is null.

Reimplemented in KoPictureClipart, KoPictureEps, KoPictureImage, and KoPictureWmf.

Definition at line 62 of file KoPictureBase.cpp.

bool KoPictureBase::save (  QIODevice *  io  )  const [virtual]
 

save file

Parameters:
io QIODevice used for saving

Reimplemented in KoPictureClipart, KoPictureEps, KoPictureImage, and KoPictureWmf.

Definition at line 88 of file KoPictureBase.cpp.

bool KoPictureBase::saveAsBase64 (  KoXmlWriter &  writer  )  const [virtual]
 

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