Temporary files created

Question

I am using the following snippet of code to create a thumbnail image:
BufferedImage tmp = new BufferedImage( w, h, type );
Graphics2D g2 = tmp.createGraphics();
if( hint != null )
     g2.setRenderingHint( RenderingHints.KEY_INTERPOLATION, hint );
g2.drawImage( ret, 0, 0, w, h, null );
g2.dispose();On Windows systems, it seems to create a temporary file called imageio####.tmp, where #### is a random integer.
Is there anyway to remove that file? Failing that, is there some way I can specify the directory they are created it? It appears that they are created in the system tmp directory. This creates a problem, since one of the requirements I have is that I not write to the users hard drive.
Shouldn't the dispose() call cleanup after itself by removing any temporary files?
Thanks,
Steve

I don't think the code you posted has anything to do with the problem. Look for use of ImageIO. It's also possible that a condition mentioned in the second bug applies, although the first bug notes that a file "imageio8733.tmp" is created, which is your problem.
Reread the bugs. This quote from the first one doesn't say you have to create an OutputStream.
A DESCRIPTION OF THE PROBLEM :
Using ImageIO.write() to write to an ImageOutputStream
results in a temporary file being created and never
deleted. The temp file is typically something like:
C:\Documents and Settings\<username>\Local
Settings\Temp\imageio8733.tmp
Explicitly calling ImageOutputStream.close() deletes the
temp file.
Again, I appreciate your response. I have reviewed my code, and nowhere do I directly call ImageIO.write(). I do not have an ImageOutputStream anywhere in my code.
I suspect the drawImage() call, or some other api call, is doing this "under the covers". I'm wondering if there is anyway around it.
