Hi
   I got a reference for the same question from Stack Overflow http://stackoverflow.com/questions/14726485/resize-an-image-resource-in-cq5/16728970#16728 970
I tried the same method
Resource resourceNew = resource.getResourceResolver().getResource(img.getFileReference());
    Asset asset = resourceNew.adaptTo(Asset.class);
    log.error("asset ****" + asset);
    Layer layer = new Layer(asset.getOriginal().getStream());
    layer.resize(200, 200);
    log.error("layer ****" + layer);
                        Image image = new Image(resource);
    String mimeType = image.getMimeType();
    ByteArrayOutputStream bout = null;
    ByteArrayInputStream bin = null;
    try {
        bout = new ByteArrayOutputStream(2048);
        layer.write(mimeType, 1, bout);
        bin = new ByteArrayInputStream(bout.toByteArray());
        asset.addRendition("resizedImage", bin, mimeType);
log.error("asset Bin" + asset);
    } finally {
        // close streams ...              
Where img is my Image object and I was able to create a rendition in the dam.
But the rendition I am getting is in File format. Is there a way by which i can change it to png format??? any Help will be appreciable..
Thanks
