ASprite.NET Version 2.0.0.0

Public Sub DrawBackgroundZoom(dPercent as Double)

• dPercent - The amount to zoom.  Pass this value as the actual percentage.  For example, send 50 to zoom to 50% of the image size.  Send 200 to scale the image to twice it's original size.  This amount is NOT cumulative--it is the actual amount to zoom.

Comments:

• Use the DrawBackgroundGetZoom function to get the actual percentage of zoom, such as 50 or 200 (rather than 0.5 or 2.0).

• The bStretch parameter for DrawBackgroundImage does not set the zoom amount (for retrieval by the DrawBackgroundGetZoom function).

• Use the DrawBackgroundZoomFitWindow to fit the image to the CustomWidth and CustomHeight size.  Then, you can retrieve the zoom amount using DrawBackgroundGetZoom.

• Sprites will work at any zoom amount.

• Scroll and Zoom can work together.  Sprites are handled internally.  The scroll amount is always based on the original size (100%) of the image.  Therefore, you don't have to modify your program's scroll values when zooming.

Example:  Zoom to 150%
