<div>
<p class="MsoNormal">I met a problem of vtkimageactor,I used jpegreader to read 12 pictures ,then used vtkimageactor to show it,one of these jpegs was rendered.then i wanted to show another pictures ,So I called SetZSlice but it didn't work. I watch the souce
of the method like below:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">void SetZSlice(int z) <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">{this->SetDisplayExtent(<br>
this->DisplayExtent[0], this->DisplayExtent[1],<br>
this->DisplayExtent[2], this->DisplayExtent[3], z, z);}<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">then I debug the program,the vtkimageactor's DisplayExtent is an array of 6 int ,valus -1,0,0,0,0,0, this is strange .Then I watch the vtkImageData which vtkimageactoe setinput,there is an arry named extent in it values 0 383 0 383 0 11,
I think this means the picture data is saved,but why the method didn't work?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">I google this problem and find some people met the same problem,but there is no solution. Anyone can help us?<o:p></o:p></p>
