Hi !

I'm trying to use a QMovie object to dislpay animation files ith extension .mng.

I First tryed without using double buffering. Here is a part of my code implemented in a SLOT connected using the QMovie::connectStatus function :
Qt Code: 
  1. case(QMovie::EndOfFrame):
  2. 	frame->setPixmap(movie->framePixmap());
  3. 	break;
To copy to clipboard, switch view to plain text mode 

As the result was flicker, I decided to use double buffering. Here is the updated code (in the smae function) :
Qt Code: 
  1. case(QMovie::EndOfFrame):
  2. {
  3. 	QPixmap pix(movie->framePixmap());
  4. 	QRect rect(0, 0, pix.width(), pix.height());
  5. 	bitBlt(frame, rect.topLeft(), &pix, rect);
  6. }
  7. break;
To copy to clipboard, switch view to plain text mode 

I have two problems :
1. When trying to display big animations the first frame is displayed partially and the others are not displayed, and I can read in the debug traces the following message :
Qt Code: 
  1. MNG error 11: (null); chunk IDAT; subcode 0:0
To copy to clipboard, switch view to plain text mode 
So what's wrong ?

2. In order to display big animations, I tryed to use a small one and then to resize it, but the result is not the one I expected : the pixmap size is resized but its content is not stretch, why ?

Thanks in advance.
