Both the Icon and IconList properties allow you to establish a frame count. The frame count is used to determine how the loaded image file is divided into a list of smaller images, or frames. The easiest way to see this is by example. Here is a single image file, 288 pixels wide and 27 pixels tall.
This image clearly has nine icons in it, but the SRP Button Control doesn't know that. So, we set the frame count to 9. In so doing, the SRP Button Control divides the width of the whole image by 9 and those are the frame. In this case, setting the frame count to 9 results in 9 32-pixel wide images.

The SRP Button Control has up to nine states, so you can supply up to nine frames in your image:
The table below shows which frame applies to each state:
