GdPictureImaging.ClearGdPicture() corrupts other instances

[rbgolfin]

I am running version 7.4.0.10. I have found that GdPictureImaging.ClearGdPicture() corrupts other instances of GdPictureImaging .

Here is my scenario:

- I open form 1 that creates an instance of GdPictureImaging and loads a tiff image.
- I open form 2 that creates another instance of GdPictureImaging and loads a different tiff image.
- On form 2 I do GdPictureImaging.ClearGdPicture() and close the form.
- I go back to form 1 and do int xx = moGdPictureImaging.TiffGetPageCount(mintImageSrcID);
- It throws an "Object Reference Not Set" exception.

If I just close form 2 and do not perform the ClearGdPicture() it works fine.

Hi,

This is the normal behavior. ClearGdPicture() method simply purge all the cache, customer garbage collector, and opened images of the GdPicture engine.
So when you call this method, you have to understand that any GdPicture Image will remain open in any part of your application. This method should be considered as a public static method of the SDK.

Hope this helps !
