java - What class(es) should I use for basic bitmap operations in GAE? -

i have code running on gae , basic bitmap manipulation. fundamentally need is:

convert bitmap 1 format (usually png). get metadata of image: size in pixels, dpi, & bitmap format. resize image. walk pixels in bitmap read and/or set them (this can slow - used).

also, terrific if there's class convert metafiles bitmap?

thanks - dave

for basic image manipulation (resize, crop, rotate etc.), can utilize images api , in particular, interface com.google.appengine.api.images.image.

the api seems back upwards many of requirements mention.
