scale images : general class to filter a xml tree (xml file)

[Eric DE MAULDE]

Hi,

I create a XML file to set images dimensions (height, width) related to their sizes (small, medium, large) by Web site
The target is to scale (... add a logo) from a saved detail image (if the asked size file doesn't exist).

My solution :

ImageProperties.xml    <--  Image.class (scale detail image and create the image file if need be - doesn't exist with the rigth height or width)    <--    Screen (call a product image)  --> display the related image

Does it exist a general java class to filter a XM file  ?
Or do you know a better solution ?

Thanks

Eric

Hi Eric,
I like this approach and, some time ago, I started a discussion on the
ML about this.

The item is still on my todo list.
The dynamic image scale with cache is something I find really
interesting to add to OFBiz.

I used with drupal this component http://drupal.org/project/imagecache
that does the same thing and could be used, may be, as a reference.

In the old thread, if I well remember, you should also find a
reference so a java library to use.

I have done something similar in my app and used the Jakarta Image-Taglib for it (which is based on the Poor Mans Image Wrapper, btw -> a great tool). It isn't a pretty solution however, since I had to work around to call a jsp (so that i could use the taglib) file from a service that would then create the scaled images and store them on the server... I would only run the service when I add new products and create all sizes I would need once.

I would argue that perhaps it is easiest, if we would add a new ImagingUtil class to the project which is based on the Poor Mans Image Wrapper (http://www.mullassery.com/software/PMIW/index.jsp) and allows instant image resizing...
