Problems with declaring a function

Targets Windows
1

I am trying to declare this function http://msdn.microsoft.com/en-us/library/windows/desktop/ms535401(v=vs.85).aspx.

I am attempting to write my first declare so excuse me if I got a very wrong idea of what OS declares are about but I am trying to declare it like this:

Declare Function Image.RotateFlip Lib "Gdiplus" (RotateFlipType as uint32) as Uint32 msgbox str(RotateFlip(0))

The msgbox is basically for testing if it works.

Thanks

I appear to be able to use GdipImageRotateFlip, without errors, instead of Image.RotateFlip. Might mean i am getting somewhere??

Declare Function GdipImageRotateFlip Lib "GdiPlus" ( handle as Integer, palette as RotateFlipType ) as Status

Enum RotateFlipType:
  RotateNoneFlipNone
  Rotate90FlipNone
  Rotate180FlipNone
  Rotate270FlipNone
  RotateNoneFlipX
  Rotate90FlipX
  Rotate180FlipX
  Rotate270FlipX
  RotateNoneFlipY = 6
  Rotate90FlipY = 7
  Rotate180FlipY = 4
  Rotate270FlipY = 5
  RotateNoneFlipXY = 2
  Rotate90FlipXY = 3
  Rotate180FlipXY = 0
  Rotate270FlipXY = 1

Enum Status:
  Ok
  GenericError
  InvalidParameter
  OutOfMemory
  ObjectBusy
  InsufficientBuffer
  NotImplemented
  Win32Error
  WrongState
  Aborted
  FileNotFound
  ValueOverflow
  AccessDenied
  UnknownImageFormat
  FontFamilyNotFound
  FontStyleNotFound
  NotTrueTypeFont
  UnsupportedGdiplusVersion
  GdiPlusNotInitialized
  PropertyNotFound
  PropertyNotSupported

Is there a quick way to copy and paste enums?

Looking further into this, you better download the “Advanced Graphics for Windows” from Aaron Ballman. (Can’t find a link but it’s included in my ASPE engine that you can download from https://alwaysbusycorner.wordpress.com/2014/03/06/xojorealbasic-abpe-the-physics-engine/

The complete GdiPlus framework is declared in it + you have an example how to use it.

Wow, I did not know such a thing existed. Is there a Mac and Linux equivalent to ‘Advanced Graphics For Windows’, thanks?

Well, MacOsLib is also included in this download (Quartz 2D) for Mac (Download the Xojo version, not the RB2007R4 version of ABPE). Linux, no idea, but I suspect not.

How do I get the data from a ‘GdiPlusImage’ as a picture format? Thanks
