|A color expression that indicates the starting transparent color.
Use the TransparentFrom and TransparentTo properties to define the transparent colors for the control. These properties have efect only if the Transparency property is True. Use the Picture property to load a picture into the control. If the Picture property points to an icon, the BackColor property defines the control's background color. Use the same value for TransparentFrom and TransparentTo as BackColor property, if you need to define a non-regular window based on an icon. By default, the transparent color of the animation (Play method) is defined by the ACS/ACF file, but you can use the TransparentFrom and TransparentTo properties to define the new transparent colors.
