Hello,
I have checked in a number of files that are part of an image I/O =
framework we are developing here at UNC. For anyone that is interested =
in I/O matters and this candidate framework, I suggest as a starting =
point the following article on Pluggable Object Factories at C++ Report:
http://www.creport.com/html/from_pages/view_recent_articles_c.cfm?Article=
ID=3D1520
My own article, ImageIO.html (in the documents directory of the =
repository), then describes how to leverage this concept for file I/O.
Please note that before checking in these new files, I performed a CVS =
checkout in a new directory at 1:45 PM on 12/17. I was unable to build =
the existing code successfully on any platform other than VisualC++ =
(Linux, SunOS, SGI all fail), and so I am unable to verify that my new =
files are cross-platform compatible with respect to the latest state of =
the repository. Therefore, I have refrained from making these new files =
part of the build process for the time being, and have not modified any =
of the CMakeLists. So I don't anticipate my changes to cause any =
problems, but please let me know as soon as possible if they do in fact =
break something; I'll be checking e-mail frequently while on vacation =
for the next three weeks.
Below is a list of all the new files I added, along w/ very brief =
descriptions of the classes:
Under Code/Common:
itkMaker.h
itkMaker.txx - pluggable object factory base class. templated over key =
type and object type
itkFileIOCommon.h
itkFileIOCommon.cxx
itkFileIO.h=20
itkFileIO.cxx - image i/o base class. does little more than define an =
interface and an abstract object factory
itkFilterFileIOToImage.h
itkFilterFileIOToImage.txx - base class for transferring image data from =
a FileIO to an Image
itkIntTypes.h - defines the integer types for cross-platform =
compatibility. probably not needed
Under Code/Interfaces/MetaImage:
itkFileIOMetaImageCommon.h
itkFileIOMetaImageCommon.cxx
itkFileIOMetaImage.h
itkFileIOMetaImage.cxx - one concrete implementation of a FileIO and =
factory to illustrate the framework.
Under Testing/Code/Common:
itkFileIOTest.cxx - uses FileIOMetaImage, Image<>, and =
FilterFileIOToImage to illustrate the API presented to developer
Under Documents:
ImageIO1.jpg
ImageIO.html - article describing the framework
I welcome your comments and suggestions, and hope that some of these =
ideas will prove to be useful in the final I/O framework.
Thanks,
-Parag Chandra
