Parameters:

size - null or an int[2] to receive the (width,height) of the image

jpegImage - Description of the Parameter

Returns:

the image data - with the necessary header for SWF

Throws:

java.io.IOException - Description of the Exception

shapeForImage

public static Shape shapeForImage(java.io.InputStream jpegImage,
                                  int[] size2)
                           throws java.io.IOException

Create a Shape for the image. The resulting shape uses the image as a clipped image fill. The shape is a rectangle just the right size to show the entire image and its origin is at the top left. Additional geometry vectors may be added to the shape if required.
