    I am getting a 640x480 bitmap image of an Xbox Kinect, and I have also made a separate programs which can send and receive images over TCP.

    Since bimaps are uncompressed I would like to convert the image to a JPEG to save bandwith. The only examples I have seen of this were for saving images.

    The code I have seen was something like this.

    Code (Text):

    Image bitmapImage = openfile(path);    //Gets image from a file path
    Image jpegImage;
    jpegImage.save(path, jpg);     //Saves a jpeg to the path
    I want to be able to get an image from the Kinect (I have code for this bit), then that the Image object and save it to another Image but as a JPEG.

    Anyone got any ideas on how to do this?

    What language are you coding in? That would be helpful information.

    From the thread title, I presume C#.

    I thought he had said C#, but couldn't find it in the body of his post. Guess I didn't look hard enough to notice it in the title.

    Mad Mike, check the System.Drawing namespace, and particularly the Image class. The Save method has an overload that lets you specify the format of the saved image.

    Yea, I'm using c#. Should have made that clear.

    At the moment I am reading in a bmp image from the kinect camera, saving it as a jpg and then opening that file and sending the jpg. I would rather just be able to convert it with out having to save it to disk first.
