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.

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.

QImage KoPictureBase::generateImage | ( | const QSize & | size | ) | [virtual] |
Generate a QImage (always in slow mode).
Reimplemented in KoPictureEps, and KoPictureImage.

bool KoPictureBase::isNull | ( | void | ) | const [virtual] |
Returns true if the picture is null.
