Examples

This example shows how long it takes to draw 100 lines on the screen each frame.

key.Initialize

Dim font
font = graphics.CreateFont ( "system", 10 )

Dim t
t = timers.Create()

Do
    graphics.Clear

    Dim i
    For i = 1 To 100
        graphics.SetLine 320, 240, rnd*640, rnd*480, argb(150, rnd*255, rnd*255, rnd*255)
    Next
    graphics.SetRect 10, 10, 120, 16, &hFF000000
    graphics.SetText "Frame time: " & timers.SplitTime(t), 10, 10, font
    graphics.Display
Loop Until key.Pressed ( vk_escape ) Or key.Pressed ( vk_windowx )
