Michael Groß commented on IMAGING-159:
--------------------------------------
Completed POJO parameter objects in
http://github.com/mgmechanics/commons-imaging/tree/IMAGING-159-POJO
Some parameters may still missing but I am on it.
I am working to remove the Map<String, Object> object which held the parameters
from all the classes and replace it by ImagingParameters resp. inherited
ImagingParameters<IMAGE_FORMAT like Jpeg, Pcx, Tiff> POJO classes. While I am
working on this the source in the branch IMAGING-159-POJO in my repository may
not compile.

> Key: IMAGING-159
> URL: https://issues.apache.org/jira/browse/IMAGING-159
> Project: Commons Imaging
> Issue Type: Improvement
> Components: imaging.*
> Reporter: Benedikt Ritter
> Fix For: Review Patch
>
>
> Currently options for image I/O are defined as Maps. The leads to the problem
> that our code has to validate parameter types when they are used:
> {code:java}
> final Object value = params.get(PARAM_KEY_COMPRESSION);
> if (value != null) {
> if (!(value instanceof Number)) {
> throw new ImageWriteException(
> "Invalid compression parameter, must be numeric: "
> + value);
> }
> compression = ((Number) value).intValue();
> }
> {code}
> This can be simplified if we define a Parameters class that provides
> additional methods like {{public int getInt(String key)}}. The implementation
> could then look up the value from the map through an exception if it is null
> or not a number.
