Description:

 Zoom Raster sets the view scale so that one pixel in the bitmap or grid item equals one pixel on the screen, to achieve the perfect resolution. To do this, the view is zoomed in or out, using the centre of the screen as the centre of the zoom.

1. Select the bitmap or grid item.
   
   
2. Select Selection, to centre the raster image on the screen.
   
   
3. Select Zoom Raster.

The width (X dimension) will always be correct, and if the bitmap’s pixels are square then the height will be correct too.

This command also operates without a bitmap or grid item being selected. In this case, SIS searches for a bitmap or grid item and zooms to it.
