May 30, 2018 Replies: 42 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. Updates v1.40 - Adds support for B4XImageViews (XUI Views). - New ScaleDownImages flag. True by default. The updated example demonstrates the usage. Note that if not using B4XImageView then you should set the image when ScaleDown = False, with XUIViewsUtils.SetBitmapAndFill. v1.31 -New FadeBorders effect. See post #9: https://www.b4x.com/android/forum/threads/b4x-bitmapcreator-effects.93608/#post-672188 v1.21 - New ReplaceColor method. v1.20 - Added PieceSize to ImplodeAnimated and added FlipVertical and FlipHorizontal methods. v1.10 - Adds TransitionAnimated method to transition between two bitmaps.

LucaMs Expert Licensed User Longtime User May 30, 2018 #2 I like especially ImplodeAnimated (and have to watch the code, I can not imagine how it is done ). Also, Erel said: The class is cross platform and compatible with B4J (v6.3+), B4A (v8.3+) and B4i (v5.0+). Click to expand... Great!

LucaMs Expert Licensed User Longtime User May 31, 2018 #6 Two very small things (one of them is my fault... as always ) 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.

It is just a single class, I know, but... for example the projects attached to the first post have different versions of BitmapCreatorEffects class; using a b4x lib...!

Erel B4X founder Staff member Licensed User Longtime User Dec 11, 2019 #11 Both options are good in this case. Why distribute as a class? 1. It was written before b4xlib feature was available. 2. It is a single class which makes it easy to add to your project. 3. It is quite simple to extend it with new features as it is a collection of very specific subs.

It is much easier to "import" (select) a library; moreover, it is a common bad abitude for many of us... having to search in which project we have used a certain class (that is, not organizing our "tools" well) Erel said: 3.

You probably don't know it but a b4xlib library contains the source code The main reason is the first; that's why I wanted to create the library, so you can simply attach it to the first post.
