WG: [vtkusers] class vtkImageImport, strange problem??

[Chunyan Jiang]

The problem is solved tentatively. Because I copied all vtk .dll to the
debug folder. Then it works. However, I don't know why it is. And I won't
include so many .dll files in the debug folder. Could some one explain to
me?

Betreff: [vtkusers] class vtkImageImport, strange problem??


I'm sorry to send the same email again. In the last mail, I attached one
picture. Maybe it is too big. And it can not pass the vtk's list moderator.
This time I attach the smaller picture.


Dear vtk users,
I meet one strange problem of class vtkImageImport. I use this class in two
applications as the same method. However, it works in one application, in
the other, it doesn't work. The error comes from the function
SetWholeExtent. Then I debug these two application and find that there are
some parameters are not same as initialization. They are compared in the
following:

Available case:
---------------------------------------------
	vtkImageImport *importer = vtkImageImport::New();

importer->SetWholeExtent(0,dimensions[0]-1,0,dimensions[1]-1,0,dimensions[2]
-1);

the parameters after "New()" are:
SaveUserArray:0
NumberOfScalarComponents:1
DataScalarType:4
BufferPointerCallback:0x00000000
---------------------------------------------

Unavailable case:
---------------------------------------------
	vtkImageImport *importer = vtkImageImport::New();

importer->SetWholeExtent(0,dimensions[0]-1,0,dimensions[1]-1,0,dimensions[2]
-1);

the parameters after "New()" are:
SaveUserArray:1
NumberOfScalarComponents:4
DataScalarType:0
BufferPointerCallback:0xbaadf00d
--------------------------------------------

The other parameters are same. And the error message is in the attachment.

How can I solve this problem? It is urgent!!
Thank you very much!
