How to transfer Images over RFCOMM connection?

[Jossnaz]

Hello


I'm looking for a way to transfer images over a SPP/RFCOMM connection. I am using bluecove.

Some kind of way to generate out of a local saved image a String or a bytearray transfer it and generate back an image.

What I'm looking for too is a way to resize images, actually only make em smaller. Best would be if that is possible on a PC (transferring a huge image which is bigger than the mobile phone cache and then trying to resize it is not really clever.)

I hope somebody got help.


thanks

nice solution found on

http://mindprod.com/jgloss/imageio.html#TOBYTES

jpeg png convert byte array bytearray imageio image io
example for testing


BufferedImage bufImage = ImageIO.read( new File( filename ) );
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write(bufImage, "png", baos);
baos.flush();
byte[] bytesOut = baos.toByteArray();
baos.close();
BufferedImage cImage = ImageIO.read(new ByteArrayInputStream(bytesOut));
ImageIO.write(cImage,"png",new File ("testest.png"));

hi Jossi,

to down-size images (rescale down) just use any of "make thumbnails" solutions,
could be any for SE, say:
