    "Alpha wipe" image transition

    A photo transition effect that wipes a new image over an old image working from left to right. Easily modified to wipe right to left, top to bottom, or bottom to top.

    Unzip into a directory.

    Copy two JPEG images into the Project folder as Back.jpg and Front.jpg, both images having the same dimensions.

    I suggest larger than 300x300 but smaller than your primary monitor since this demo does not attempt to scale them. The Form will be resized to fit these images. To best see the effect the two images should be quite different.

    Then just run it. Front will be "wiped" over Back, then they will be swapped and the process repeats.

    You can tweak a few of the constants used, to alter the effect a bit. Probably a lot of room for bug fixes and other improvement too so don't worry about tinkering.

    Think of it as a first draft example of how you might do transitions of this kind.
