<DIV><FONT face=Arial size=2>Hi!</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Arial CE" size=2>The platform I work on is Borland's C++
Builder 5.0 installed on</FONT></DIV>
<DIV><FONT face="Arial CE" size=2>W2000k Proffesional(patched with SP1).
VTKDLL.dll & VTKDLL.lib , </FONT></DIV>
<DIV><FONT face="Arial CE" size=2>that I use in my BCP projects, </FONT><FONT
face="Arial CE" size=2>was generated by use of John Biddiscombe's
bvtkCxxWizard(some of the classes were excluded</FONT></DIV>
<DIV><FONT face="Arial CE" size=2>from VTK library, but I believe that they
weren't essential ones).</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Arial CE" size=2>My problem is following. I created a simple
pipeline which includes:</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Arial CE" size=2>-vtkBMPReader,</FONT></DIV>
<DIV><FONT face="Arial CE" size=2>-vtkImageGradientMagnitude,</FONT></DIV>
<DIV><FONT face="Arial CE" size=2>-vtkBMPWriter.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Arial CE" size=2>Then, I provide file name to BMP which I
obtained from Open File Dialog.</FONT></DIV>
<DIV><FONT face="Arial CE" size=2>When I try to execute Update method(I believe
it should be executed),</FONT></DIV>
<DIV><FONT face="Arial CE" size=2>VTK's debug window is opened. The message goes
something like this:</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Arial CE" size=2>Generic Warning: vtkBMPReader.cxx, line
477</FONT></DIV>
<DIV><FONT face="Arial CE" size=2>File operation failed. row=0, Read=128,
Skip0=0, Skip1=0, FilePos= -1.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Arial CE" size=2>If I skip executing Update method on bmp
reader, and I execute, as last,</FONT></DIV>
<DIV><FONT face="Arial CE" size=2>bmp writer's Write method I also get some
message about some </FONT></DIV>
<DIV><FONT face="Arial CE" size=2>obsolete methods(?) and latter warning as
well.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Arial CE" size=2>I also tried to read set of images with
BMPReader in volume. I set the</FONT></DIV>
<DIV><FONT face="Arial CE" size=2>data extent to, e.g. (0, 127, 0, 127, 2, 10),
file pattern to "%s_%02d.bmp", </FONT><FONT face="Arial CE" size=2>and file
prefix as well(extracted as substring from first .bmp file in </FONT><FONT
face="Arial CE" size=2>Open Dialog's list). Then I execute Update method, but it
all went wrong. </FONT><FONT face="Arial CE" size=2>It set the InternalFileName
to something like "image_00.bmp". I believe it should set InternalFileName(is it
to "image_02.bmp"(executing</FONT></DIV>
<DIV><FONT face="Arial CE" size=2>ComputeInternalFileName(2) proves it).
</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Arial CE" size=2>Now I would like to ask you guys, from this
mailing list, to give some</FONT></DIV>
<DIV><FONT face="Arial CE" size=2>hint for solution on this puzzling problem. If
anyone has any working</FONT></DIV>
<DIV><FONT face="Arial CE" size=2>example coded in C++ which uses vtkBMPReader
and, if possible,</FONT></DIV>
<DIV><FONT face="Arial CE" size=2>runs on the same or similar platform to mine,
I would like him to </FONT></DIV>
<DIV><FONT face="Arial CE" size=2>send me code(or its excerpt, whatever)zipped
on my e-mail.</FONT></DIV>
<DIV><FONT face="Arial CE" size=2>And at last, could someone tell me what should
I set in my IDE</FONT></DIV>
<DIV><FONT face="Arial CE" size=2>to be able to step into some of the vtkXXX
classes' method during</FONT></DIV>
<DIV><FONT face="Arial CE" size=2>debugin session.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Thank in advance.</FONT></DIV>
