Draw the image in a painter.
No, this isn't as simple as painter.drawPixmap(). This method ensures that the best quality is used when printing, scaling the 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.

| QDragObject * KoPictureImage::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!

save file
- Parameters:
-
io QIODevice used for saving
