viewtool example demonstrates how to use View related APIs.
Allows for exact sizing of MicroStation's standard views. View size can be specified with an absolute pixel size (widthxheight) or by a ratio. What this enables you to do is render your view (File->Save As) and create raster images of an exact size (640x480, 1024x768, etc.).
Normally when doing a File->Save As you can only specify the width or the height of the output image...the other value is computed by taking the value you entered and multiplying it by the current view ratio. Now you can set what the current views ratio is so images will be the size you want without having to muck about trying to stretch views to get the right size.
