Member Function Documentation
| bool KoPictureBase::isNull | ( | void | ) | const [virtual] |
Returns true if the picture is null.
Reimplemented in KoPictureClipart, KoPictureEps, KoPictureImage, and KoPictureWmf.

| void KoPictureBase::draw | ( | QPainter & | painter, | |
| int | x, | |||
| int | y, | |||
| int | width, | |||
| int | height, | |||
| int | sx = 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.

| 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.

| bool KoPictureBase::save | ( | QIODevice * | io | ) | const [virtual] |
save file
- Parameters:
-
io QIODevice used for saving

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