Hello,
I'm using swt libraries to handle images, and I need to convert an Image
into a File, and viceversa.
I could convert a file into an image :
Image img = new Image(null,file.getAbsolutePath());
but I sometimes get java.lang.OutofMemory exception, when the image is
really big.
I also need to do the viceversa, and I have NO clue how to convert an image
into a file. I mean I know you can do it using an ImageLoader and saving it,
but if possible, I'd like not to save it on hard disk.
Any hints?
Thanks a lot,
Larissa

Try using -Xmx to increase the memory available to Java.

Thanks for the tip, but I don't want to save the image on hard disk!
I want to save it on a "file" in the sense of a file type java variable!
Any idea how to do it?
Many thanks,
Lari

Do you mean java.io.File? That's nothing but a path.

Yes, I mean java.io.File.
So when I want to save something on a "file" type, it has to be stored on
hard disk first? Because I have to give the path to the file object?
