Converting java.awt.image to IplImage

[GoogleCodeExporter]

Hi,
Is there a performant method to convert a java.awt.image or an array of
floats or int to an IplImage?
I tried set2D, but it's slow, like 7 seconds for 200x200 on 2GHz.

This can be done in the usual Java way, by first copying the Image object into a
BufferedImage, and then copying that into an IplImage. Although copying is 
efficient,
it still involves two copies, but that's the best that can done. For example, 
given
an Image object "image", this should work:

BufferedImage bufferedImage = new BufferedImage(image.getWidth(null),
image.getHeight(null), BufferedImage.TYPE_3BYTE_BGR /* or whatever type you 
like */);
Graphics g = bufferedImage.getGraphics();
g.drawImage(image, 0, 0, null);
g.dispose();
IplImage iplImage = IplImage.createFrom(bufferedImage);
