[Tig] Re: GraphicsMagick and DPX
Mon Jul 25 04:45:51 BST 2005
The latest GraphicsMagick development snapshot (1.2.020050721 or
later) supports reading and writing DPX files with YCbCr encoding.
Rec 601 and Rec 709 luma are supported. 4:4:4 and 4:2:2 encoding are
supported. Alpha is supported.
The only deficiencies I am currently aware of are:
o Below-black and above-white is clipped since YCbCr is transformed
to full-range RGB rather than Rec 709 "studio" RGB. A later
version may offer a "studio" RGB mode.
o 4:2:2 subsampling is slow.
Development snapshots may be downloaded from
Currently only source packages are available for this snapshot.
Windows binaries are pending.
Please let me know about any problems encountered.
