copied!<p>If you want to use a selector you will need to create a servlet for it that extends the AbstractImageServlet. You would start out with something like this:</p> <pre><code>@Component @Service @Properties({ @Property(name="sling.servlet.resourceTypes", value="sling/servlet/default"), @Property(name="sling.servlet.selectors", value="resize"), @Property(name="sling.servlet.extensions", value={"jpg", "png", "gif"}), @Property(name="sling.servlet.methods", value="GET") }) public class ImageResizeServlet extends AbstractImageServlet { //... code. } </code></pre> <p>sling.servlet.selectors would be the selector name you would want to set. For example:</p> <pre><code>//in the servlet @Property(name="sling.servlet.selectors", value="resize") //in the jsp image.setSelector("resize"); </code></pre> <p>Within your class, you would want to override the writeLayer method. Something like this:</p> <pre><code>@Override protected void writeLayer(SlingHttpServletRequest req, SlingHttpServletResponse resp, AbstractImageServlet.ImageContext c, Layer layer) throws IOException, RepositoryException { // set new width and height int width = 100; int height = 100; Image image = new Image(c.resource); if (!image.hasContent() || width == 0) { resp.sendError(HttpServletResponse.SC_NOT_FOUND); return; } // get style and set constraints image.loadStyleData(c.style); // get pure layer layer = image.getLayer(true, true, true); Layer newLayer = ImageHelper.resize(layer, new Dimension(width, 0), null, null); if (newLayer != null) { layer = newLayer; } String mimeType = image.getMimeType(); if (ImageHelper.getExtensionFromType(mimeType) == null) { // get default mime type mimeType = "image/png"; } resp.setContentType(mimeType); layer.write(mimeType, mimeType.equals("image/gif") ? 255 : 1.0, resp.getOutputStream()); resp.flushBuffer(); } </code></pre> <p>In our custom solution we handled everything in the writeLayer method and not the createLayer method. So we overwrote createLayer.</p> <pre><code>@Override protected Layer createLayer(AbstractImageServlet.ImageContext c) throws RepositoryException, IOException { // don't create the layer yet. handle everything later return null; } </code></pre> <p>We also overwrote createImageResource</p> <pre><code>/** * {@inheritDoc} * * Override default ImageResource creation to support assets */ @Override protected ImageResource createImageResource(Resource resource) { return new Image(resource); } </code></pre> <p>Hope that helps.</p>
