Set the scaleImage property dynamically according to the size of the image

 scaleImage="RetainShape"  works correctly for a larger image but for a smaller image, it enlarges(stretches, hampering the image quality) it as per either by width or height of the report element .



<image scaleImage="RetainShape" hAlign="Center" vAlign="Middle">

<reportElement x="10" y="10" width="534" height="300" uuid="d813ec39-6f47-4361-9d82-c312924c2ba0"/>




Can we set the scaleImage property Dynamically? if (image is large)  scaleImage="RetainShape"  else scaleImage="Clip"

Well, I got some help on Stackoverflow and achieved it  by creating  a conditional style and applying it to the image taghttp://community.jaspersoft.com/sites/all/libraries/ckeditor/plugins/smiley/images/lightbulb.gif
