@gwlucastrig
>great suggestion from @gwlucastrig : "use one call for setSubImage, rather
than 4 separate calls for setSubImageX, Y, Width, Height."
I started making this change in the `TiffImagingParameter`. First the
`public void setSubImage(Integer width, Integer height, Integer x, Integer y)`.
All good so far.
But when I finished and started adding the getter, I was thinking in Python
or JS, and wanted to return all the 4 parameters at once
:disappointed_relieved: Then I realized I would have to create another class to
return the 4 parameters… do you have any suggestion for the getter of the
subimage in the tiff imaging parameter class?
Thanks!

> 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.
