It wraps this Github project. Posting the following:
1. B4A project demonstrating the library
2. B4A library files (2x Jar and 1 x XML) - copy them to your additional library folder
3. The Java code
Note: there is a file called placeholder.pnd in the B4A project's /Objects/res/drawable folder. It needs to be there is you start a new project (it needs to be set to read-only)
It seems to work best with images that are just about 100% square.
....or pass a color such as for eg "#66FF0000" to make the colors transparent
Sample code:
