uhhh....
Maybe you meant:
BufferedImage snap = new BufferedImage(subw, subh, TYPE_INT_RGB);
>>> Graphics2D g2d = snap.createGraphics();

Yes, if you want alpha you should pass in TYPE_INT_ARGB.
Note that the default compositing mode of the freshly retrieved graphics
object is SRC_OVER. The code sample still works fine since the newly
constructed image is all 0's (transparent pixels) so copying your source
image "over" the fully transparent image works just fine.
But, if you try to reuse the image and copy a different section of the
source image into it at a later stage then you might want to do the
image copy using "g2d.setComposite(AlphaComposite.SRC)"...

OK; thanks.
If you didn't want a snapshot, I can outline other
ways, but I'm guessing that this is probably what you wanted...?
Yep. What allowed you to know that TYPE_INT_RGB was the correct
parameter to pass in the BufferedImage constructor? If it helps, I
know that the source image often has an alpha value set. Would I use
TYPE_INT_RGBA in this case?
Thanks again for helping this newbie out.
Best,
