Nice!

Im sorry, but I have to ask ... Does this save on executable size?

I'm sorry, but I don't understand your question.

The example shows a pointer to the memory, where PB stored the image in memory.
When you save via SaveImage(ImageNo,...) the changed image will be saved. (modified pixels and new size (original: 20x20 / new: 400x400))

Try this:

Code: Select all

Procedure CloseMainWindow()
  If IsImage(ImageNo) : SaveImage(ImageNo,"c:\demo1.bmp") : FreeImage(ImageNo) : EndIf
  If IsWindow(MainWindowNo) : CloseWindow(MainWindowNo) : EndIf
EndProcedure

I hope this will help a little...

P.S.

This will center the window on screen:

Code: Select all

Procedure OpenMainWindow()
  Protected WinPosX.l, WinPosY.l
  ExamineDesktops()
  MainWindowNo = OpenWindow(#PB_Any,0,0,0,0,"click on image to change color!",#PB_Window_SystemMenu|#PB_Window_ScreenCentered)
  If MainWindowNo
    MainWindowID = WindowID(MainWindowNo)
    If CreateGadgetList(MainWindowID)
      If InitImage()
        ImageGG = ImageGadget(#PB_Any,10,10,0,0,ImageID)
        WinPosX = Int((DesktopWidth(0)-(ImageWidth(ImageNo)+20))/2) : If WinPosX<0 : WinPosX=0 : EndIf
        WinPosY = Int((DesktopHeight(0)-(ImageHeight(ImageNo)+20))/2) : If WinPosY<0 : WinPosY=0 : EndIf
        ResizeWindow(MainWindowNo,WinPosX,WinPosY,ImageWidth(ImageNo)+20,ImageHeight(ImageNo)+20)
        ProcedureReturn #True
      EndIf
    EndIf
  EndIf
  ProcedureReturn #False
EndProcedure

Sorry, I can't modify the code of my first post without error
