[vtkusers] Trying to read a set of jpg slices

[Goodwin Lawlor]

Hi Rodrigo,

If your filenames are Image1.jpg, Image2.jpg etc

Try

jpegReader->SetFilePattern("%s%d.jpg");
jpegReader->SetFilePrefix("C:/VTK5.10/DATA/MatlabTest/JPG/Image");


With this FilePattern, the reader replaces "%s" with the FilePrefix, then
appends the file number, then appends the extension ".jpg"

Note you had a typo in the FilePrefix originally - "Imagen"
