Bitmap-Width
This property identifies the width in pixels of the image displayed in the Bitmap control. The bitmap strip identified by the Bitmap-Handle property is divided into several smaller images. The width of each image is the value assigned to this property.
This property is evaluated only if Bitmap-Scale and Bitmap-Number are set as well. If Bitmap-Scale and Bitmap-Number are not set or Bitmap-Width is omitted, then the Size property is used to specify the width of the image.
 
Example - Define a bitmap control that will show image strip 3 from a series of icons 16x16 pixels
