B4A Library DriveImageView

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

    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.

    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.
