roRectangle

Object Creation: This object is created with coordinate and dimension parameters.

CreateObject("roRectangle", x As Integer, y As Integer, width As Integer, height As Integer)

SetRectangle() calls made by widget objects (e.g. roImageWidget.SetRectangle()) honor the view-mode or aspect-ratio conversion mode set by the user. If the user has set the video player for letterboxing, it will occur if the video does not fit in the new rectangle exactly.

Rectangles with 4K Video Modes 

When the player is using a 4K video mode (e.g. 3840x2160x60p), rectangles still operate as if the total screen area is 1920x1080 (unless full-resolution graphics is enabled). They are then scaled by a factor of 2 when the video is output. For example, to display a full-screen 4K video, set the roRectangle instance to 0,0,1920,1080; to display an additional HD video in the top-right quadrant of the screen, set another roRectangle instance to 960,0,960,540.

Note that, while 4K video is output at a 1:1 pixel ratio, graphics elements (roImageWidget, roCanvasWidget, etc.) are upscaled to match the size of the 4K video output. This occurs irrespective of the size of the original image and widget rectangle: For example, an image in a 960x540 rectangle will first be downscaled to 960x540, then upscaled to 1920x1080. If you want to display images without upscaling on 4K video modes, display them in a video window using the roVideoPlayer.PlayStaticImage() method (or enable full-resolution graphics).
