[seam-issues] [JBoss JIRA] Updated: (JBSEAM-4633) Apply/decorate graphicImage with rounded corners

Apply/decorate graphicImage with rounded corners ------------------------------------------------ Key: JBSEAM-4633 URL: https://jira.jboss.org/browse/JBSEAM-4633 Project: Seam Issue Type: Feature Request Components: JSF Controls Reporter: Kasper Sørensen Priority: Minor Fix For: The future It would be great with a graphic image transformation that adds rounded corners to an image. Most JavaScript libraries can add rounded corners to DIV-elements and more, but not IMG-elements. This is why it would be great to perform such rounding of edges on the server side. I've implemented this feature using this code: {code} @Override public void applyTransform(Image image) throws IOException { Integer height = image.getHeight(); Integer width = image.getWidth(); BufferedImage sourceImage = image.getBufferedImage(); BufferedImage targetImage; Graphics2D graphics; if (image.getContentType() == Type.IMAGE_JPEG) { targetImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB); graphics = targetImage.createGraphics(); graphics.setBackground(Color.WHITE); } else { // transparent background if supported targetImage = sourceImage.createGraphics().getDeviceConfiguration() .createCompatibleImage(width, height, Transparency.BITMASK); graphics = targetImage.createGraphics(); graphics.setBackground(new Color(0, 0, 0, 0)); } graphics.clearRect(0, 0, width, height); RoundRectangle2D.Float roundedRectangle = new RoundRectangle2D.Float(0, 0, width, height, radius, radius); graphics.setClip(roundedRectangle); graphics.drawImage(sourceImage, 0, 0, null); graphics.dispose(); image.setBufferedImage(targetImage); } private Integer radius = 20; public void setRadius(Integer radius) { this.radius = radius; } public Integer getRadius() { return radius; } @Override public Object saveState(FacesContext context) { Object[] state = new Object[2]; state[0] = super.saveState(context); state[1] = radius; return state; } @Override public void restoreState(FacesContext context, Object state) { Object[] states = (Object[]) state; super.restoreState(context, states[0]); radius = (Integer) states[1]; } {code}
