Image size bug?

  What is the error you are seeing? Only speculating, but are you ever setting the context back to to the screen before you attempt to draw page1?

  The image displayed is full screen height, but only 500 pixels wide

  EDIT: incidentally, it looks like others have had this problem before too, and there is a bug with setContext()/displayMode() in some cases:

  A couple of workarounds: you either need to move your displayMode(FULLSCREEN) out of the setup() function and into the global scope, or you need to wait until draw() to render to an image using setContext().

  workaround 1:

  
  displayMode(FULLSCREEN)
  
  function setup()
      spriteMode(CORNER)
  
      page1 = image(WIDTH,HEIGHT)
      setContext(page1)
      sprite("Documents:besht1")
      setContext()
  end
  
  function draw()
      sprite(page1,0,0)
  end
  

  and workaround 2:

  
  function setup()
      spriteMode(CORNER)
      displayMode(FULLSCREEN)
  end
  
  doOnce = true
  
  function draw()
      
      if doOnce then
          doOnce = false
          page1 = image(WIDTH,HEIGHT)
          setContext(page1)
          sprite("Documents:test3")        
          setContext()
      end
      
      sprite(page1,0,0)
  end
  

  I'm not sure why this is happening though. Maybe someone at TLL might have an explanation?

  .@toadkick this is due to the fact that calling displayMode() while in setup() will animate the sidebar out (this is intentional behaviour). The canvas is not resized until animation is complete.

  Calling displayMode() while outside of setup() explicitly does not animate the display change (so users can launch in fullscreen without any artefacts at startup).

  One way we might be able to resolve this is to block the thread until animation completes. Thanks for providing the workarounds.

  Interesting. Does calling displayMode() during draw() cause the output window to animate as well?

  .@toadkick it should, though I wouldn't recommend calling it rapidly (i.e. it should be part of a conditional, or triggered by user interaction).
