Abstracting the render target code to its own class will help clean up our main game class as well as create a space for fullscreen effects. The first will be zoom.

Here's what the render handler can do.

• Create and manage the Render Target
• Handle scaling and fitting to the screen - CalculateRenderDestination()
• USe a method to apply changes to zoom - use integer increments for pixel perfect scaling
• Encapsulate the render pipeline - sprite batch beginning to end for the render target

Render Handler Zoom

Trying out zoom using the render target. The render target is set by retroWidth and retroHeight (320x180).

• ZoomIn() should smoothly zoom to 50% retroWidth x retroHeight, 160x90

• ZoomOut() should smoothly zoom to 150% retroWidth x retroHeight, 480x270
