Thank you, it works!

Now i only have to make sure the inputstream that i
got from the transferable is a pict format that
Quicktime understands. How can i ensure the
inputstream (image/x-pict) be a quicktime pict format.

1. if you don't need java.awt.Image
converting code is fairly simple (with QTJava) THANK
YOU APPLE.

public static void saveAsJPEG(File inFile,File
outFile){
try{
Pict pict = Pict.fromFile(inFile);
GraphicsExporter gex = new
GraphicsExporter(QTUtils.toOSType("JPEG"));
gex.setInputPicture(pict);
QTFile qtf = new QTFile(outFile);
gex.setOutputFile(qtf);
gex.doExport();
}catch(Throwable t){}
}

so just call
saveAsJPEG(new File("test.pict"),new
File("test.jpg"));

2.if you do need java image do the following

try{
Pict pict = Pict.fromFile(new
File("test.pict"));
byte []pictbytes = pict.getBytes();
//check here 512 length 0 header
//if you have that header do nothing
//if you don't have that header you must add it:
byte []newpictbytes = new
byte[512+pictbytes.length];

System.arraycopy(pictbytes,0,newpictbytes,512,pictbytes.length);

QTHandle qt = new
QTHandle(newpictbytes);
GraphicsImporter gc = new
GraphicsImporter(QTUtils.toOSType("PICT"));
gc.setDataHandle(qt);
QDRect qdRect = gc.getNaturalBounds();

GraphicsImporterDrawer myDrawer = new
quicktime.app.view.GraphicsImporterDrawer(gc);
QTImageProducer qtProducer = new
QTImageProducer (myDrawer,
new
Dimension(qdRect.getWidth(),qdRect.getHeight()));
Image img =
Toolkit.getDefaultToolkit().createImage(qtProducer);

//YOU'RE ALL SET


}catch(Throwable t){
System.out.println("Picture Exception "+t);
}

Margaret, you don't have to look for 1.3.1 to

work

with qtjava

qtjava 6.1 works happily with 1.4.X (QT >= 6.4)


that code will work with 1.4.X
Pict p = ....
QTHandle qt = new QTHandle(p. getBytes());
GraphicsImporter gc = new

//YOU CAN USE EXPORTER IF YOU WISH

out that command
you can convert it to jpeg/tiff for sure I'm

not

sure about gif
/*
possible values are
jpeg
tiff
gif
png
JPG
jpg
JPEG

use

javax.imageio.ImageIO.getReaderFormatNames()

My Mac OS has 1.4.2 installed. Where can i

find

the

jdk 1.3.1? so that i can run the QTJava

correctly? I

tried on apple site, and no luck. My

application

needs to run on both window and mac. so i

would

like

to use QTJava.

Thanks

Thanks for the reply.

My application needs to do multi-platform.
