[Insight-developers] JPEG lib: 8/12/16 bits and lossless

[Mathieu Malaterre]

Hello,

	As discussed in last week TCON, I will be progressively integrating 
GDCM(*) into ITK. GDCM is a dicom library that support a great variety 
of images (jpeg lossy/ lossless, RLE compression, YBR image, using the 
full DICOM dictionnary... ). For more information please go to:

	http://www.creatis.insa-lyon.fr/Public/Gdcm

	The first step, is to update the current jpeg lib (which
only support lossy 8bits) shipped with ITK to support:

- lossless jpeg (which is needed to fully support DICOM images).

- To support 8bits, 12bits and 16bits (16bits is only for lossless image).

	There will be then three jpeg libraries, one for 8bits, one for 12bits 
and one for 16bits, with the proper name mangling (prepending symbols 
with itk_jpeg8 for the 8bits one ...)

	As a side effect we will loose the ability to use the system jpeg lib. 
Let me know ASAP if this could affect in any way your project, so we can 
work out a solution.
