first ist makes only a simple text that moves in the window.later it sould read the *.kdenlivetitle file direct an paint from the QGraphicsView. After this, we could enable the Start-/Endview, to let the title scroll and zoom.
But first ist works with drawText on an QImage. regards marco Am 10.07.2009 um 16:01 schrieb Mathias Friman:

The idea is to somehow copy the code from the qimage producer, but instead of loading an image, we would write text on that image using the Qt classes. The result will be something like the pango producer, but I think that with Qt we should be ableAfter some quick tests, it seems like this is sadly not possible. Drawing text over a QImage requires a QApplication to be created (because some stuff needs to be initialized), and creating it in an MLT module does not seem possible... So I will stop working on that for now, unless someone with a good knowledge of Qt4 can find another way to solve that problem...i tested this shortly. this small sample here can write to QImage without QApplication, (uses QCoreApplication) and does not need QtGui #include <QCoreApplication> #include <QImage> #include <QPainter> int main(int argc, char** argv) { QCoreApplication app(argc, argv); QImage image(200, 200, QImage::Format_ARGB32); QPainter painter(&image); painter.drawText(100, 100, "Test"); image.save("test.png"); return 0; } with that and the code fro kdenlive for the titler, we sould be able to move the code into mlt. this should let us create then also scrolling titles. (zooming, scrolling ...) regards marcoAre you using pango now for the titler? I did not get that impression. I don't see how you would be integrating all that you have in the titler with producer_pango?!No, currently, the kdenlive titler created png images, so titles in Kdenlive are just images. regards jb ------------------------------------------------------------------------------ Check out the new SourceForge.net Marketplace.
