AutoCAD Inventor :: Change Image Background To White

I want to change the backgroun color to a solid white before i save an image of an .iam to file.

so far:

Inventor.Color bgColor = InvApp.TransientObjects.CreateColor(255, 255, 255);
Camera.SaveAsBitmap("C:\Users\Dan\Desktop\test.jpg", 800, 800, bgColor);

This does nothing to the image, same gradient BG set from the colorschemes.

i tried:

InvApp.ColorSchemes.BackgroundType = BackgroundTypeEnum.kOneColorBackgroundType;

just for giggles and it does in fact change the BG to a solid grey. But after that, i see no way to change the BG. 

InvApp.ColorSchemes.Item("Presentation").Activate;

does not work either as the .Item sub class does not even under the color schemes object. im sure i am passing the wrong color object to the save as bitmap method anyway -
