    BitmapCreatorEffects class includes all kinds of very simple to use image effects.
    The class is cross platform and compatible with B4J (v6.3+), B4A (v8.3+) and B4i (v5.0+).
    Example:
    Code:
    'Greyscale an image:
    Dim GreyImage As B4XBitmap = effects.GreyScale(ExistingBmp)
    'Blur an image:
    Dim BlurImage As B4XBitmap = effects.Blur(ExistingBmp)


    The attached examples demonstrate the various methods.

    BitmapCreatorEffects depends on XUI and BitmapCreator libraries.

    Note that all of the example code is implemented in a class that is shared between the three projects. This way we can get 99% code reuse.

    Updates

    Version 1.21 - New ReplaceColor method.
    Version 1.20 - Added PieceSize to ImplodeAnimated and added FlipVertical and FlipHorizontal methods.
    Version 1.10 - Adds TransitionAnimated method to transition between two bitmaps.

    The latest version of BitmapCreatorClass is included in the B4J project. You should take it as-is and add to your project.
    The Example class from the B4J project can also be used in the other projects.

    I like especially ImplodeAnimated (and have to watch the code, I can not imagine how it is done :D).

    Also,
    Great!

    Very complex.

    I would change:

    Code:
    Public Sub ImplodeAnimated (Duration As Int, PieceSize As Int, Bmp As B4XBitmap, ImageView As B4XView) As ResumableSub
    '...
        Dim GroupSize As Int = PieceSize

    PieceSize: 30 - 5 - 1 :

    Two very small things (one of them is my fault... as always :p:()

    1) BitmapCreatorEffects was updated to v. 1.20 but there is stil this comment:
    'Version 1.10

    2) the variable GroupSize never changes its value; so you could refine the routine using the parameter directly.
    (I LOVE F7 + rename :))



    [Just two details because I was looking at the code to answer a question submitted by a member]

    1) I've uploaded a new zip with the correct version in the comment (the code is the same).

    2) This is not important.
