<p style="margin-bottom: 12pt;"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">Hi Iv<span>án,</span><br>
<br>
<span>Thank you to keep helping me. Please let me know if
I understood correctly :</span><br>
<span>From what you told me, for each picture I use as
input, I will apply my filter 2 times but using 2 different types for the
image. And then you said that there was a problem about downcasting. But since
I only have 1 of those pictures that will be useful, maybe the result
downcasting isn't a problem ? For instance, if my input picture a short type, I
will only need the one in the container[1] without caring about the result of
the container[0]. On the opposite, if it is a unsigned char, I will only need
the one in the container[0] instead of the container[1]. </span><br>
<span>I think that this method must work but the problem
is the time eaten by applying 2 times a filter ?</span><br>
<span>Well, maybe I misunderstood the way you suggested
me to do. </span><br>
<span>Otherwise I can still try to use the polymorphism
as you told me before but it's kind of complicated since I am using ITK as a
DLL in my program that is intended to be run on IDL. </span><br>
<br>
<span>Thank you again for spending your time on this
problem,</span><br>
<br>

Thank you for answering. I am actually storing image in containers (importing
an image from IDL and exporting it back with filters applied on it). That is
why I need to have different kind of pixel and I intented to implement it such
as we don't need to know what the original pixel type is. <br>

issue. With typedef you are defining new types which are valid only in the
space between the braces and those types no longer exist (go out of scope)
after them. So when you reach the point where you define the image types,
InputPixelType and OutputPixelType don't exist because they cannot be seen.</span></font></p>

<p style="margin-bottom: 12pt;"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">Hi,<br>
<br>
I was wondering if you could change the InputPixelType easily ? <br>
I have tried something like :<br>
<br>
int test = 1; // just to be sure it
enters the first if for InputPixeltype to be defined<br>
if( test == 1)<br>
{<br>
typedef unsigned char
InputPixelType; <br>
typedef unsigned char
OutputPixelType; <br>
}<br>
else<br>
{<br>
typedef short InputPixelType; <br>
typedef short OutputPixelType; <br>
}<br>
<br>
typedef itk::Image< InputPixelType, 2 > InputImageType;<br>
typedef itk::Image< OutputPixelType, 2> OutputImageType;<br>
<br>
But It doesn't work: gives that error " Error
4 error C2065: 'InputPixelType' : undeclared
identifier
e:\tmp\Imageimport\binarytest.cxx 62 "
<br>
If i put directly one type it works, but if i put an "if", even
though I am sure in goes in, the InputPixelType isn't known. Could you explain
me why it doesn't recognize it ?<br>
<br>
Thank you in advance, <br>
Regards,<br>
<br>
Frédéric<br>
