Member Function Documentation
| QPixmap RenderedDocumentPagePixmap::accessiblePixmap | ( | ) |
Definition at line 65 of file renderedDocumentPagePixmap.cpp.
| QPainter * RenderedDocumentPagePixmap::getPainter | ( | ) | [virtual] |
Returns a pointer to the paintDevice (in most implementation either a QPixmap, or a QPrinter).
The pointer returned is valid as long as *this RenderedDocumentPage exists. This method is used by the renderer to draw on the page.
Implements RenderedDocumentPage.
Definition at line 41 of file renderedDocumentPagePixmap.cpp.
| virtual int RenderedDocumentPagePixmap::height | ( | ) | [inline, virtual] |
Returns the height of the page in pixel.
- Warning:
- If you are implementing DocumentRenderer::drawPage(), it may be tempting to compute the image size in pixel, using page->height() and page->width(). DON'T DO THAT. KViewShell uses transformations e.g. to rotate the page, and sets the argument 'resolution' accordingly; these changes are not reflected in page->height() and page->width(). Similar problems occur if KViewShell required a shrunken version of the page, e.g. to print multiple pages on one sheet of paper. See the documentation of DocumentRenderer::drawPage() to learn how to compute the sizes properly.
Reimplemented from RenderedDocumentPage.
Definition at line 47 of file renderedDocumentPagePixmap.h.
| unsigned int RenderedDocumentPagePixmap::memory | ( | ) |
Returns the amount of memory used by this pixmap.

| ) |
| void RenderedDocumentPagePixmap::resize | ( | const QSize & | size | ) |
| virtual void RenderedDocumentPagePixmap::returnPainter | ( | QPainter * | pt | ) | [inline, virtual] |
This implementation delete the QPainter *pt (and thereby initiates the drawing).
Implements RenderedDocumentPage.
Definition at line 38 of file renderedDocumentPagePixmap.h.
| virtual QSize RenderedDocumentPagePixmap::size | ( | ) | [inline, virtual] |
Returns the size of the page in pixel.
Implements RenderedDocumentPage.
Definition at line 45 of file renderedDocumentPagePixmap.h.
| virtual int RenderedDocumentPagePixmap::width | ( | ) | [inline, virtual] |
Returns the width of the page in pixel.
