Java Servlet framework that does things like rencoding images to preferred format etc -

-

are there frameworks/libraries provide servlets/filters etc handle reencoding on fly of images.

  • interpret accept headers , output file, reencoding new format if necessary checking actual format of original image file.
  • provide low , high quality version of image.
  • re encode image new dimensions. width , height parameters might query string parameters.

i create versions of file in formats, @ upload time seems overkill. rather lazily create rencoded file , stick in cache if gets served again etc.

you donot need framework. folowing:

  1. upload image. see apache commons fileupload
  2. process uploaded file using of
  3. when processed, provide link download.
