Bring your ideas to life with the APIs and additional memory available for development on the Nokia Asha platform. Join this webinar to learn how much you can do in the area of imaging, with the Image Scaling API and the Image Processing API. You’ll also get detailed guidelines on how to work with the camerainterface and how to create special effects and filters.

5. Manager
Player ControlData Source
javax.microedition.media
URLs
“capture://image”
“capture://video”
Live viewfinder VideoControl
RecordControl

6. Form videoForm;
Item videoItem;
Player player;
VideoControl videoControl;
player = Manager.createPlayer("capture://image");
//player = Manager.createPlayer("capture://video");
player.prefetch();
player.realize();
player.start();
videoControl = (VideoControl)player.getControl("VideoControl");
videoItem = (Item)videoControl.initDisplayMode(VideoControl.USE_GUI_PRIMITIVE, null);
videoForm.append(videoItem);

7. byte[] imageBytes = videoControl.getSnapshot(null);
Image image = Image.createImage(imageBytes, 0, imageBytes.length);
ImageItem imageItem = new ImageItem("", image, Item.PLAIN, "");
videoForm.append(image);
String fileName = System.getProperty("fileconn.dir.photos”)
+
"CapturedImage.jpg";
FileConnection file = (FileConnection) Connector.open(fileName,
Connector.READ_WRITE);
if (!file.exists()) file.create();
OutputStream out = file.openOutputStream();
out.write(imageBytes);
out.close();
file.close();

8. byte[] imageBytes = videoControl.getSnapshot(null);
//byte[] imageBytes = videoControl.getSnapshot(“width=640&height=480”);
Image image = Image.createImage(imageBytes, 0, imageBytes.length);
ImageItem imageItem = new ImageItem("", image, Item.PLAIN, "");

Connector.READ_WRITE);
if (!file.exists()) file.create();
OutputStream out = file.openOutputStream();
out.write(imageBytes);
out.close();
file.close();

9. RecordControl recordControl;
recordControl = (RecordControl)player.getControl("RecordControl");
recordControl.setRecordLocation(System.getProperty("fileconn.dir.photos”) +
"CapturedVideo.mp4");
recordControl.startRecord();
...
...
recordControl.stopRecord();

10. • Displaying live camera viewfinder;
• Taking snapshot;
• Recording video;

13. ImageScaler imageScaler = new ImageScaler(sourceImageFilePath, destinationFilePath);
imageScaler.addListener(this);
Integer requestId = new Integer(imageScaler.scaleImage(newWidth, newHeight, true));
. . .
public void scaleFinished(int requestId, int result) {
...
}

15. MediaProcessor mediaProcessor = GlobalManager.createMediaProcessor(JPEG_TYPE);
mediaProcessor.addMediaProcessorListener(this);
...
mediaProcessor.setInput(inputStream, MediaProcessor.UNKNOWN);
...
mediaProcessor.setOutput(byteArrayOutputStream);
ImageEffectControl imageEffect =
(ImageEffectControl) mediaProcessor.getControl(
"javax.microedition.amms.control.imageeffect.ImageEffectControl");
imageEffect.setPreset("monochrome");
imageEffect.setEnabled(true);
mediaProcessor.start();
...
public void mediaProcessorUpdate(MediaProcessor processor,
String event,
Object eventData){
...
}

17. • Image Scaling API
• Image Effects with APPS
