SaveVectorState()

Syntax

SaveVectorState()

Saves the current vector drawing state to be restored later. Multiple states can be saved on a stack and restored in the reverse order they were saved.

The following information is saved with this command:
- The coordinate transformations
- The drawing source
- The drawing font
- The clipping path

Note that the current path is not saved by this command.

Parameters

None.

Return value

None.

Example

  If OpenWindow(0, 0, 0, 400, 200, "VectorDrawing", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
    CanvasGadget(0, 0, 0, 400, 200)
    LoadFont(0, "Times New Roman", 20, #PB_Font_Bold)    

    If StartVectorDrawing(CanvasVectorOutput(0))
    
      VectorSourceColor(RGBA(255, 0, 0, 255))
      VectorFont(FontID(0))
      
      MovePathCursor(20, 20)
      DrawVectorText("Normal text")
      
      ; Changes made to the drawing state within this block do not affect the other commands
      SaveVectorState()
        MovePathCursor(120, 160)
        RotateCoordinates(120, 160, -50)
        VectorSourceColor(RGBA(0, 0, 255, 255))
        DrawVectorText("Rotated text")
      RestoreVectorState()
      
      MovePathCursor(220, 140)
      DrawVectorText("Normal text")

      StopVectorDrawing()
    EndIf
    
    Repeat
      Event = WaitWindowEvent()
    Until Event = #PB_Event_CloseWindow
  EndIf
