[Tig] GraphicsMagick DPX bug, update needed!

All of the GraphicsMagick snapshots prior to 1.2.020051001 (issued 
today) have a bug in that the last position in text header fields is 
reserved for a null byte.  This is a problem since text header fields 
in DPX are not null terminated and some of the fields in the motion 
picture part of the header need all of the space.  As a result, a few 
header fields were corrupted when a file was converted.

The development snapshots may be downloaded from


If you have installed a previous snapshot of GraphicsMagick, please 
update ASAP.

As a reminder, when building from source code, please make sure to 
supply the option --with-quantum-depth=16 so that internal sample 
storage is 16 bits.

Many thanks to the user who discovered and reported the bug.
