Thumb Files

You need to create thumb images if you create a trackbar. There are two types: SeekThumb and VolumeThumb. They define the images that indicate the values of the media content position (seeking) and the volume. You can use one file and define it for use by both SeekThumb and VolumeThumb. Unlike the other art files, the thumb files are defined in the Trackbars section of the skin definition file.

Here is a typical SeekThumb file:

Here is a typical VolumeThumb file:

These two button files look the same but are slightly different sizes. The left image is the normal view that the user sees, and the right image is the Pushed image the user sees when they tap on the button.

You may want to make certain areas of the thumb images transparent. This will allow you to create thumb images in shapes other than rectangular. Any region of a thumb image that you fill with the color specified by the RGB value 255, 0, 255 will appear transparent in your skin.
