<DIV><FONT face=Arial size=2>Hi,</FONT></DIV>
<DIV><FONT face=Arial size=2>Do these things. 1) Get HWND for your MFC control
(I think you are using Picture). 2) Get its client rect (width and height). 3)
Invoke viewer->SetParentId method and pass HWND to it. 4) Invoke
viewer->SetSize(width,height).</FONT></DIV>
<DIV><FONT face=Arial size=2>This is not a bug.</FONT></DIV>
<DIV><FONT face=Arial size=2>HTH</FONT></DIV>

<DIV><BR></DIV><FONT color=#0000ff size=3>hello , vtk users and developers
, </FONT><BR><FONT color=#0000ff size=3>
</FONT><BR><FONT color=#0000ff size=3> I find a vtk
<STRONG><FONT color=#ff0000>BUG</FONT></STRONG> now . </FONT><FONT
color=#0000ff size=3>and the bug is just as follows :</FONT><BR><FONT
color=#0000ff size=3> I use VC++ and VTK to show a dcm image
. and I build a project , its base class is CFormView . and </FONT><BR><FONT
color=#0000ff size=3>then I use vtkDICOMImageReader and vtkImageViewer2 to
show the image in an Picture of MFC . but here </FONT><BR><FONT
color=#0000ff size=3>is the <STRONG><FONT color=#ff0000>bug</FONT></STRONG>
:</FONT><BR><FONT color=#0000ff size=3> all of my
code are just : </FONT><BR><FONT color=#0000ff size=3>vtkDICOMImageReader
* reader = vtkDICOMImageReader::New();</FONT><BR><FONT color=#0000ff
size=3>
reader->SetDataByteOrderToLittleEndian();</FONT><BR><FONT color=#0000ff
size=3> reader->SetFileName("D:/Data");</FONT><BR><FONT
color=#0000ff size=3> reader->Update();</FONT><BR><FONT
color=#0000ff size=3>vtkImageViewer2 * viewer =
vtkImageViewer::New();</FONT><BR><FONT color=#0000ff size=3>
viewer->SetInput(reader->GetOutput());</FONT><BR><FONT color=#0000ff
size=3> viewer->SetSlice(0);</FONT><BR><FONT
color=#0000ff size=3></FONT> <BR><FONT color=#0000ff
size=3> and then I run it , I find the dcm
image appears ! however , the dcm image is not in the Picture
</FONT><BR><FONT color=#0000ff size=3>of MFC , but in a vtk render
window . how surprising ! because I do not use the function Render !
</FONT><FONT color=#0000ff size=3>at </FONT><BR><FONT color=#0000ff size=3>the
same time , if I use vtkImageViewer , it will be OK .
</FONT><BR><FONT color=#0000ff size=3> So , I want to ask :
is this a vtk <STRONG><FONT color=#ff0000>BUG</FONT></STRONG> ? or
vtkImageViewer2 can not show the dcm image ? but from </FONT><BR><FONT
color=#0000ff size=3>the description of this class , we can see
: vtkImageViewer2 is a convenience class for displaying a
</FONT><BR><FONT color=#0000ff size=3>2D image . or this class is not perfect
and we can not use this class now ?</FONT><BR><FONT color=#0000ff
size=3> if this is not a bug , why does this happen ? and
what is wrong with my code ? how can I use this
</FONT><BR><FONT color=#0000ff size=3>class correctly ?</FONT><BR><FONT
color=#0000ff size=3></FONT> <BR><FONT color=#0000ff
size=3> thank you for any help !</FONT><BR><FONT
color=#0000ff size=3></FONT> <BR><FONT color=#0000ff
