    Image comparison

    Hello everybody,

    Is there a way to compare two images with ASP code and return true if images are same and false if they are different?

    Thanks.

    Re: Image comparison

    Regarding ASP? Can't help, but you may want to clarify image comparison.

    For example: Save a bitmap as JPG and they may appear the same, but individual RGB values will probably be different due to JPG compression. Likewise, resize the same bitmap to 1/2 size and you have 2 bitmaps that are similar in appearance, but not the same size.

    I'm sure this topic has been touched on before and searching the graphics portion of the forum may help.
