Effect Class

[Force Code]

The GDI+ documentation describes the Effect Class and numerous subclasses of it (HueSaturationLightness, Tint, ColorBalance, Blur, etc.) I can't find these in any of the GDI+ header files downloaded as part of the PlatformSDK from Microsoft. Also, they don't even appear to be in gdiplus.dll. Does anyone know the header files and dll they're in. Thanx

They should be in gdiplus.dll.. Check that you have the latest version.. I know that GDI+ is fully supported in Visual Studio so you could use that if you have access to that? I'm not sure if it's supported in the Express versions, if it is you could try using Visual C++ express free from MS Hope this helps! --PerspX

Do you know which header files they're declared in?

[Perspx]

Well the main header file for GDI+ is obviously gdiplus.h. There are then other GDI+ header files which are used, however I believe that they are all included from gdiplus.h anyway, so that shouldn't be a problem.. What happens at compile time with your project? Hope this helps! --PerspX

The compiler's not finding the declarations (compiler error). I'm using Dev-C++ as a compiler (mingw - its gnu or something). I downloaded the PlatformSDK a couple of weeks ago, and have compiled and ran GDI+ code using The Bitmap, Font, and TextureBrush classes, etc. with no problem. I have numerous GDI+ headers, none of them contain the Effect classes. If you can do a "Find in File HueSaturationLightness *.h", I'd appreciate it.

GDI+ is included with the operating system, not a part of Visual Studio. As stated by Perspx, according to the docs for the Effect class: "Declared in Gdipluseffects.h, include gdiplus.h" Mark

Hmm.. It is pretty odd.. I have looked through the VS header files and there doesn't appear to be any reference to any of the effects classes as previously mentioned (I am using VS 2005 Professional). I have used GDI+ on several occasions, but I have not used any of the effects classes. I'm very sorry I cannot help you any further. --PerspX

[Perspx]

Odd.. my copy of Visual Studio doesn't seem to have Gdipluseffects.dll :S sorry about that.. I would have been able to help you sooner otherwise.. Thanks for clearing that up Mark :) --PerspX

:) I didn't clear anything up (well, maybe the part about GDI+ not being part of Visual Studio ;)). AFAIK you had it right - include gdiplus.h should be all the OP needs to do. Cheers! Mark
