B4A Library [B4X] BitmapCreator Effects

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:

'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.

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

Also,

The class is cross platform and compatible with B4J (v6.3+), B4A (v8.3+) and B4i (v5.0+).

Great!

V1.10 released with TransitionAnimated:

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

Very complex.

I would change:

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 :

 

[Erel]

V1.20 released with the above change and Flip methods.

 

[LucaMs]

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.

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

(I LOVE F7 + rename )



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

 

[Erel]

BitmapCreatorEffects was updated to v. 1.20 but there is stil this comment:

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

2) This is not important.

 

[Erel]

V1.21 uploaded to first post. New ReplaceColor method:

V1.31 released with FadeBorders effect:

It softens the borders and makes the image embed in a nicer way.

Why not a b4xlib?

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]

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.

1. It was written before b4xlib feature was available.

I know, of course

2. It is a single class which makes it easy to add to your project.

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)

3. It is quite simple to extend it with new features as it is a collection of very specific subs.

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.

 

[Erel]

Done. Note that you don't need to add the empty folders.

Useful info

I learnt something good today. Thanks to LucaMs.

How to make a class into b4xlib.

I will study the codes and try same in future.

I will study the codes and try same in future.

On site there are many much better examples of this, from which to learn

Thank you, Anand.

Thank you, Anand.

I meant to say, Now I have both "class" and "b4xlib" codes for same logic and this will help me learn faster by comparing the changes require for the conversion

Missed updating the manifest...
