Android Question X2 library documentation

Best to start here: https://www.b4x.com/android/forum/threads/xui2d-x2-v2-0-2021.131279/
There are links to other tutorials.

And please ask any question you have.

Thank you Erel for your answer.
I already have used the link to the 20 apps examples. But i need some primary informations.

My basic questions would perhaps be uninteresting for the forum. With an exhaustive documentation of X2 Library, I would avoid asking your help for elementary functions.

If I can ask a first question certainly very simple: I want to display an image containing a character drawn on a background color RGB 0,0,0, without displaying the background color, in order to see the character move strictly cut out.

Thank you for your help.

Best to convert the image to PNG and recolor the black color to transparent. It can also be done at runtime with BitmapColorEffects.
