## Detailed Description

Image.

Note:
  This is the container for an Image in the general sense. From this container you should be able to request information like:
  - Origin
  - Dimension
  - PixelFormat ... But also to retrieve the image as a raw buffer (char *) Since we have to deal with both RAW data and JPEG stream (which internally encode all the above information) this API might seems redundant. One way to solve that would be to subclass gdcm::Image with gdcm::JPEGImage which would from the stream extract the header info and fill it to please gdcm::Image...well except origin for instance

Basically you can see it as a storage for the PixelData element. However it was also used for MRSpectroscopy object (as proof of concept)

Examples:

  CompressImage.cxx, ConvertToQImage.cxx, CreateARGBImage.cxx, CreateCMYKImage.cxx, csa2img.cxx, GenFakeImage.cxx, GetJPEGSamplePrecision.cxx, HelloVizWorld.cxx, and PatchFile.cxx.

## Member Function Documentation

double gdcm::Image::GetDirectionCosines | ( | unsigned int | idx | ) | const

const double* gdcm::Image::GetDirectionCosines | ( |  | ) | const

Return a 6-tuples specifying the direction cosines A default value of (1,0,0,0,1,0) will be return when the direction cosines was not specified.

double gdcm::Image::GetIntercept | ( |  | ) | const`[inline]`

double gdcm::Image::GetOrigin | ( | unsigned int | idx | ) | const

const double* gdcm::Image::GetOrigin | ( |  | ) | const

Return a 3-tuples specifying the origin Will return (0,0,0) if the origin was not specified.

Examples:
  HelloVizWorld.cxx.

double gdcm::Image::GetSlope | ( |  | ) | const`[inline]`

double gdcm::Image::GetSpacing | ( | unsigned int | idx | ) | const

const double* gdcm::Image::GetSpacing | ( |  | ) | const

Return a 3-tuples specifying the spacing NOTE: 3rd value can be an aribtrary 1 value when the spacing was not specified (ex. 2D image). WARNING: when the spacing is not specifier, a default value of 1 will be returned
