to open on linux think this should work for most desktops

Code:

Case #PB_OS_Linux : ProcedureReturn RunProgram("xdg-open",FileName, "")

Hi idle,

Thank you, that worked perfectly.

------------------------------------

Updated:
- added 1 menu item
-- Open Control Panel: adds the ability to fine-tune the drawing effect
- applied the patch by idle to the OpenOriginalImage Procedure

NB*: Settings are save to an ADS (Alternate Data Stream) attached to the default image (only available in the Windows OS).

Your app crashes here on Win 7 (64-bit) and PureBasic v5.62 (32-bit). Crashes if I run it from the PB source, or from the compiled exe. No error message in the IDE, just the error in the screenshot below.

SetProcessDpiAwarenessContext is for Win 10 only, so I fixed it by changing the SetDpiAwarenessContext() procedure to this:

Code:

Procedure SetDpiAwarenessContext()
  If OSVersion()=>#PB_OS_Windows_10
    user32 = OpenLibrary(#PB_Any, "user32.dll")
    If user32
      SetProcessDpiAwarenessContext = GetFunction(user32, "SetProcessDpiAwarenessContext")
      SetProcessDpiAwarenessContext(#DPI_AWARENESS_CONTEXT_SYSTEM_AWARE)
      CloseLibrary(user32)
    EndIf
  EndIf
EndProcedure

Hi Dude,

Thank you for pointing out the OS limitation using SetProcessDpiAwarenessContext; problem should now be fixed.

NB*: All of my other posts using this Function have also been patched.

Updated (Windows):
- image sizes configured to use the built-in PureBasic DPI compiler option
