Vectors with 32 bit signed integers: with 2, 3, 4, 5, 6, 7, 8, 9, 10, 16, and 32 components.Vectors with 8 or 16 bit signed integers: with 2, 3, 4 components.Matrix types: 3x3, 4x4, 5x5, 6圆 float and double.
Scalar types: 8,16, 32, and 64 bit signed and unsigned integers, float, double.If a file cannot be loaded because the voxel components cannot be converted then try other voxel types which are larger or may fit better to the stored voxel type. Note that files could be stored in another voxel type - then the voxel type is automatically cast to the selected one.
This is the voxel type to be used for the loaded file. include < vtkMetaImageReader.h > Inheritance diagram for vtkMetaImageReader: legend Collaboration diagram for vtkMetaImageReader: legend Detailed Description read binary UNC meta image data One of the formats for which a reader is already available in the toolkit is the MetaImage file format.

Use the ImageLoad module for full 3D paged tiff files of any data type.
The itkImageFileReader reads tiff file written with MeVisLab only as 2d and in 8 bit without paging which leads to limited data quality and dimension when loading MeVisLab example data which are stored in that format. 16 bit signed integer vector with three components are the best matching type. Note that 8 bit integer vectors are not useful for many RGB images, because they use signed integers with ranges from -128 to 127 and RGB values often exceed the ranges. If color channels are stored interleaved (r,g,b,….r,g,b,…r,g,b)the images can be read into 3d integer vector voxels and then converted to a color image with the module TypeToScalars using Output Dimension C. Color images can only be read correctly if color channels are stored in separate image planes (r,r,r,….g,g,g,…b,b,b). The different types of ImageIOs can support data of varying dimensionality. For large images this can lead to out of memory problems. File loading maps the entire image in memory. Use ImageLoad for MeVisLab example data. itkMetaImageReader, itkMetaImageWriter Routines that wrap MetaIO for reading and writing ITKS's Spatial Objects (tubes, blobs, ellipses, meshes, etc.) are in Insight/Code/SpatialObject Certain examples, such as the MetaImageViewer, also require FLTK (a cross-platform user interface library available from ).
