[ITK Community] [Insight-users] Compressing Tif files

[Fethallah Benmansour]

Hi Bill,

I hope you had a great weekend.
I followed the modification you suggested (and rebuild ITK of course).
Unfortunately, the output images are still uncompressed.

In addition, close to the line you mentioned, I can see:

TIFFSetField(tif, TIFFTAG_JPEGQUALITY, 75); // Parameter

Could you please add that as a parameter of itkTIFFImageIO in you gerrit
patch ?

Kind regards,

--
Fethallah
