So, the code should look like this:
Okay, I've implemented your code example and am able to get a picture into an image object in Revolution. The pictures I grab from stills or movies don't look right however. You can see what the image should look like here <http://www.mangomultimedia.com/developer/revolution/good_image.jpg> and what the image I am getting in Revolution looks like here <http://www.mangomultimedia.com/developer/revolution/bad_image.jpg>.
I have tried various methods of putting an image into the GWorld (going to a certain time in the movie and putting that into the GWorld as well as using the QT API call GetMoviePict/GetMoviePosterPic) with the same result.
Any ideas on what might be happening?
Here is the code:
// Get movie dimensions and create offscreen GWorld
GetMovieBox(mv, &movieFrame);
NewGWorld(&theGWorld, k32ARGBPixelFormat, &movieFrame, NULL, NULL, (GWorldFlags)0);
SetGWorld(theGWorld, NULL);
// get image from movie and put into GWorld thePicHandle = GetMoviePosterPict (mv); EraseRect(&movieFrame); DrawPicture(thePicHandle, &movieFrame);
LockPixels(GetPortPixMap(theGWorld)); thePixMap = *(GetPortPixMap(theGWorld));
if (thePixMap->baseAddr != NULL) {
rdata.sptr = thePixMap->baseAddr;
rdata.length = movieFrame.right * movieFrame.bottom * 4;
SetVariableEx(args[0], "", &rdata, &retvalue);
retstr = (char *)malloc(8);
sprintf(retstr, "%s", "Success");
} else {
retstr = (char *)malloc(8);
sprintf(retstr, "%s", "Failure");
}UnlockPixels(GetPortPixMap(theGWorld)); DisposeGWorld(theGWorld); DisposeHandle((Handle)thePicHandle); CloseMovieFile(refnum); DisposeMovie(mv);
