      It should be useful to have a XSL helper to resize an image, keeping the aspect ratio, to fit in a rectangle with specified maximum dimensions.

          [CMS-1267] Helper to resize an image keeping the aspect ratio (as a fiel of structured content)

          Done with 2 xsl functions :

          • to resolve and resize image with keeping ratio 
            resolver:resolveBoundedImage(imageType, imagePath, maxWidth, maxHeight)
          • to resolve an image with specific width and height 
            resolver:resolveImage(imageType, imagePath, width, height)

          with namespace xmlns:resolver="org.ametys.cms.transformation.xslt.ResolveURIComponent"

          Okay.
          What might be interesting too would be to be able to manage image rendering "profiles" in the back office : "thumbnail" (100x100 max), "full", and so on.
          Image would be called like http://.../plugins/explorer/view/thumbnail/imageid.ext
          This would make caching easier, too (one filesystem directory by profile).

          This will not be done the xslt way but directly through a pipeline

          For example :
          http://..../plugins/exporer/view?id=...&max-width=100&max-height=100

          Acceptable parameters could be :

          • max-width
          • max-height
          • min-width
          • min-height
          • width
          • height

          A cache of modified image have to be created to avoid performance issues.

          This system allow to always store images as they are, and to transform them at read time. (Can be using it as a thumbnail somewhere and as a normal sized image somewhere else.
