ScreenGrab()

void ScreenGrab	(	const string &in	file_name,
		int	w,
		int	h,
		bool	transparentBG
	)

Capture the specified screen and save to file. Note, VSP_USE_FLTK must be defined

int screenw = 2000;                                             // Set screenshot width and height
int screenh = 2000;
 
string fname = "test_screen_grab.png";
 
ScreenGrab( fname, screenw, screenh, true );                // Take PNG screenshot

Parameters

[in]	file_name	Output file name
[in]	w	Width of screen grab
[in]	h	Height of screen grab
[in]	transparentBG	Transparent background flag

SetBackground()

void SetBackground	(	double	r,
		double	g,
		double	b
	)

Set the background color

SetBackground( 1.0, 1.0, 1.0 );                                 // Set background to bright white

[in]	r	Red 8-bit unsigned integer (range: 0-255)
[in]	g	Green 8-bit unsigned integer (range: 0-255)
[in]	b	Blue 8-bit unsigned integer (range: 0-255)

SetGeomDisplayType()

void SetGeomDisplayType	(	const string &in	geom_id,
		int	type
	)

Set the dispay type of the specified goemetry

string pid = AddGeom( "POD" );                             // Add Pod for testing
 
SetGeomDisplayType( pid, DISPLAY_DEGEN_PLATE );                       // Make pod appear as Bezier plate (Degen Geom)
