@Schlumpf
Ich habe deine Beispiel etwas modifiziert.
Code: Alles auswählen
EnableExplicit
#Window1 = 0
#Image1 = 0
#ImgGadget = 0
#max_iteration = 128
#width = 800
#height = 600
Define.d x0 ,y0 ,xtemp ,cr, ci
Define.i i, n, x, y ,Event ,color
Dim Color.l (255)
For n = 0 To 63
Color( 0 + n ) = RGB( n*4+128, 4 * n, 0 )
Color( 64 + n ) = RGB( 64, 255, 4 * n )
Color( 128 + n ) = RGB( 64, 255 - 4 * n , 255 )
Color( 192 + n ) = RGB( 64, 0, 255 - 4 * n )
Next
If OpenWindow(#Window1, 0, 0, #width, #height, "'Mandelbrot set' PureBasic Example", #PB_Window_SystemMenu )
If CreateImage(#Image1, #width, #height)
ImageGadget(#ImgGadget, 0, 0, #width, #height, ImageID(#Image1))
For x.i = 1 To #width -1
StartDrawing(ImageOutput(#Image1))
For y.i = 1 To #height -1
x0 = 0
y0 = 0;
cr = (x / #width)*2.5 -2
ci = (y / #height)*2.5 -1.25
i = 0
While (x0*x0 + y0*y0 <= 4.0) And i < #max_iteration
i +1
xtemp = x0*x0 - y0*y0 + cr
y0 = 2*x0*y0 + ci
x0 = xtemp
Wend
If i >= #max_iteration
Plot(x, y, 0 )
Else
Plot(x, y, Color(i & 255))
EndIf
Next
StopDrawing()
SetGadgetState(#ImgGadget, ImageID(#Image1))
Repeat
Event = WindowEvent()
If Event = #PB_Event_CloseWindow
End
EndIf
Until Event = 0
Next
EndIf
Repeat
Event = WaitWindowEvent()
Until Event = #PB_Event_CloseWindow
EndIf
Man kann nun auch jederzeit abbrechen.
