Re: Frustration with Java/Cocoa/Quicktime--are simple things really this hard to do?

I'm not sure but here is possible way to convert pict to NSImage

1. there is a way to create NSImage from NSPasteboard
public NSImage(NSPasteboard aPasteboard)

2. there is PICTPboardType

so you can use for example???
public static NSPasteboard pasteboardByFilteringData( NSData data, String type)

3. NSData you can create with public NSData(byte[] bytes)

and finally bytes you can receive from pict,getBytes();


byte []buffer = pict.getBytes();
NSData data = new NSData(buffer);
NSPastboard pboard = NSPasteboard.pasteboardByFilteringData(data, NSPasteboard.PICTPboardType);
NSImage image = new NSImage(pboard);


I didn't try that code, I don't have big experience with Cocoa
but it looks like it should work

let me know it it work, please

Thanks, Dmitry, that definitely solves one half of the problem. Let's see if someone can fill in the other
half :-)

Thanks,

I don't know about NSImage, but PICT to javaImage I probably can help you:

ImagePresenter ip = ImagePresenter.fromPict(pict);
QTImageProducer ip = new QTImageProducer(ip,size);
java.awt.Image javaImage = java.awt.Toolkit.getDefaultToolkit().createImage(ip);

and size is desirable size of your image

I'm trying to do what I think should be a very simple thing--pull out the first frame of a movie file using Java and Quicktime, scale it to a thumbnail, and set it as the icon of that file.

I expected the hard part to be finding the calls necessary to get the image, scale it, and set a file icon. In fact, I seem to have identified necessary calls (I don't know if they're actually correct, but by their descriptions they seem to be :-) ). The real difficulty lies in the fact that I'm dealing with three different representations of images--PICT, NSImage, and Java images--and I cannot figure out how to translate between these formats. And of course, I can't find any documentation that refers to this sort of thing. It's this last point that really frustrates me, and if someone can point to any decent documentation concerning this, I'd be most grateful.

Thanks,
Ken
