A class named TJPEGImage already exists

Hi,
I think there should be a check if the class is already registered in TGDIPlus.RegisterPictures. I use 3rd-party component where Jpeg and PngImage classes registered too. So, when It loads before mormot I got exception there.

Re: A class named TJPEGImage already exists

If you do not need the classes to be registered, do not call TGDIPlus.RegisterPictures method.

I use this to init Gdip without registering:

if Gdip = nil then
Gdip := TGDIPlus.Create('gdiplus.dll');  

Make this call in the FormCreate event of the main application form, or in the "initialization" of the unit.

I don't call this method in my code.

Do a global search to see if RegisterPictures is being called somewhere in your project, or dependent units.

And check if NOTSYNPICTUREREGISTER was defined or undefined.

In SynGdiPlus.pas (154) It is defined as:

{$define NOTSYNPICTUREREGISTER}
