I believe these are formats for Unix but someone else may know better.

Not sure what you mean by 'defaults' but if you have a 400 x 300 image, it
will export with those dimensions at (I believe) the native display
resolution.  I don't believe there are any configurable settings for PNG.

Also, you may not want to rule out JPEG.  Depending on what your app does, a
JPEG image with minimum compression (JPEGQuality = 100) should have very
minimal loss.  If you need alpha channel support, however, PNG is your only
option.
