Hello george,
ImageReader should be improved because two parameters: width and
height funcionality is limited:
* The behavior is the following: if both the new width and
height values
* are positive, the image is rescaled according to these new
values and
* the original aspect ration is lost.
* Otherwise, if one of the two parameters is zero or negative, the
* aspect ratio is maintained and the positive parameter indicates the
* scaling.
* If both new values are zero or negative, no scaling takes
place (a unit
* transformation is applied).
There should be aditional parameter "keepRatio", because it is
impossible to guess if uploaded image is wider or higher. For
example I want to make thumbnails not wider than then 100 and not
higher than 70.
There is a patch for this:
http://issues.apache.org/bugzilla/show_bug.cgi?id=30417
For some reason that I lost track of, this hasn't been committed yet...
thanks for the reminder and I will try to get that loose end tied up :-)
Note, there are two patch files there... take only the second one.

Yes, that is totally the way to do it.
