Paul Austin created IMAGING-227:
-----------------------------------

             Summary: Improve random access into byte source
                 Key: IMAGING-227
                 URL: https://issues.apache.org/jira/browse/IMAGING-227
             Project: Commons Imaging
          Issue Type: Improvement
          Components: imaging.common.*
    Affects Versions: 1.0-alpha2
            Reporter: Paul Austin


Currently getInputStream(start) is marked as final and it reads through the=
 stream to skip bytes.

For specific sources such as File or URL with byte ranges it'd be more effi=
cient to seek=C2=A0straight to the specified offset.

Also it'd be useful to cache the length of a file. Especially if a ByteSour=
ceUrl was implemented.

I'm looking to see if commons-imaging could be improved to support efficien=
t access to [https://www.cogeo.org|https://www.cogeo.org/]=C2=A0(Cloud opti=
mized GeoTIFF) served from a web server.
