    [VB6] Creation of GIF-animation with the transparent background.

    Hi everyone!
    This project allows to create an GIF animations with the transparent background. As far as i know the GDI+ doesn't allow to set the property of "Disposal Method" in the "Graphic Control Extension" block, therefore each next frame is overlayed to the previous frame. For the opaque frames it's doesn't matter. In order to solve this issue i decide to change the needed bytes manually in the raw GIF file.
    It allows to prevent the restrictions of the transparent frames. Also this example contains the oct-tree class, which calculates the optimal palette for the each frame. There are the ability of the additional settings: threshold of the transparency, duration, and number of the loops for entire animation. For the disabling of the transparency enough set the threshold to zero. The greater the value of the threshold field the greater semitransparent pixels become transparent completely.
