Detailed Description

ImageIO for handling Mevis dcm/tiff images,

PROPERTIES:

developed using gdcm 2.0.10, tiff 3.8.2 and itk 3.10.0
only 2D/3D, scalar types supported
input/output tiff image expected to be tiled
types supported uchar, char, ushort, short, uint, int, and float (double is not accepted by MevisLab)
writing defaults is tiled tiff, tilesize is 128, 128, LZW compression and cm metric system
default extension for tiff-image is ".tif" to comply with mevislab standards

GDCM (current 2.0.12):

gdcm header during reading is stored as (global) metadata to fill in the gdcm header when writing. All 'image' values, eg voxelsize, dimensions etc are overwritten, except min/max value of the image and intercept/slope.

TIFF (current 3.9.1):

ITK (current 3.14.0):

FUNCTIONALITIES:

reading gdcm file always 3D to allocate memory for spacing, dimensions etc gdcm::DataSet header, storing header into metadict using attribute to read standard values, except min/max (somehow is not supported by gdcm). The superclass may resize the variables depending on the dimensions (eg spacing, dimensions etc). Therefore when reading we check whether the image is 2d or 3d based on dcm header file, and do a re-sizing of the vector if required.
writing gdcm file fixed adding comments to see which version has been used pixeltype of dcm header is unsigned short for int, float and double images (see bugfix 20 feb 09)

todo

streaming support, rgb support
inch support for tiff
user selection of compression
implementing writing tiffimages if x,y < 16 (tilesize)
add uniform testing for linux, windows, 32/64 bits in particular for reading/creating/writing dcm files and all header values, as well 2d/3d. Things to consider for testing 1. proper handling position 2. proper handling pixeltype and sign 3. windows/linux testing 4. both dcm and tiff (especially dcm file handling)

20 Feb 2009 bugfixed; always set the pixeltype of the dcm image to unsigned short when writing, otherwise the origin is not read in correctly by mevislab (for int, float, double) 30 sep 2009 bugfix: consistent handling of 2d/3d throughout code, thanks to Stefan Klein for pointing out of this bug which revealed after usage on 2d on windows and thanks for his suggestions to fix this.
