Supported Java Sound formats are outlined in the Java Sound FAQ. The Java Media Framework (JMF) builds on top of the Java Sound engine and APIs. JMF provides support for quite a few additional ...more

A (Java) image does not have a resolution so it is not possible to get the resolution of an image. Resolution (dpi) is not really an attribute of an image. An image is simply a rectangle of pixel...more

Java 3D will not replace VRML. In fact, the two are largely complementary. VRML is predominantly a standard file format for 3D data for the Web, while Java 3D is predominantly a 3D gra...more

Yes, you can use the capture functionality in the Java Media Framework (JMF) to capture a video stream from an attached video camera. For more information, please refer to the JMF spec and docu...more

Some support for JPEG streams is provided in Java 2 via Java 2D, but not as a core platform API. JPEG is supported via the com.sun.image.codec.jpeg package. JPEG streams can in turn be ...more

The specifications for MPEG codecs are asymmetric. That is to say, it takes much more work to encode an MPEG bitstream than it does to decode it. This is by design, so that decoders can...more

Java 2D's BufferedImages and Sun's JPEG encoder package make short work of this. In order to save snapshots from java.awt.Components into JPEG files, you simply: Create a BufferedImage ...more

Check out Jonathan Knudsen's columns on java.oreilly.com plus the archive of my Media Programming JavaWorld columns at: www.javaworld.com/javaworld/topicalindex/jw-ti-media.html I...more

Yes. Use a BufferedImage to retrieve the image and an AffineTransform to scale it. Here is some example code: public class Thumbnail extends ImageIcon { public Thumbnail(ImageIcon original...more

BufferedImage is a powerful new capability provided by Java 2. You can use the BufferedImage to access the pixel-by-pixel RGB information to decide if the pixels fall within some arbitr...more

You can fade an image using a Java 2D convolve operation akin to the edge detection discussed in my JavaWorld column, "Image processing with Java 2D", at: www.javaworld.com/jw-...more

I am not aware of a Java 3D scene graph-to-VRML file exporter, though something should conceivably be possible to write (I think...not having done it yet myself). You should be able to ...more

The vector math optional package is currently only included with Java 3D implementations, although vector math support is certainly useful for other applications besides 3D apps. Download Java...more

Yes: Core Java Media Framework Essential JMF: Java Media Framework Programming with the Java Media Framework more

I have written several articles for JavaWorld magazine on the Java Media APIs including some on the Java Media Framework (JMF), which enables streaming audio (and video, and other things) in Java...more
