Hello,

So I need to explicitly call the drawImage method on the Image that I
created using (Frame)foo.createImage for each frame? The only way I see to
do this is get the graphics member of the frame and use its drawImage
method, which takes an ImageObserver... do I need to write this as well, if
not where can I get a copy of the ImageObserver for this object? Also if I
have to call drawImage for each frame, how do I know if it is safe to make
the call(ie. is the setPixels call synchronous or asynchronous).
I re-wrote my Producer to use a Vector to store the Consumers, now it seems
that the initial InfoGrabber Consumer does not bail out after the first
imageComplete weird...
I am sorry about all the questions, I just know that I am getting valid
frame pixel data and I just cant seem to get the Producer/Consumer classes
to work with my frame sequences. It must be apparent, I dont know why I
cant see it.
Thanks again...
