Output TIFF has problematic FillOrder

[paulmelis]

I'm using IM to create a fading-out image sequence of a single input image. I'm using the composite command with a changing blend factor to combine the input image with a black image. Both input and output are in TIFF, but I noticed that the output image uses a FillOrder of 2 (lsb-to-msb). From what I read about this tag it's very uncommon to use anything other than FillOrder=1 (msb-to-lsb). Furthermore, the input image has FillOrder=2 so I don't understand why it would change. The reason I actually ran into to this is that FFmpeg doesn't seem to be happy to process TIFF files with FillOrder=1 (not surprisingly).

Here's relevant info from the TIFF files and used composite command:

This is on an Ubuntu 10.04.2 LTS x86_64 system, with IM 6.5.7-8 (7:6.5.7.8-1ubuntu1.1)

The TIFF writer option

Code: Select all

-define tiff:fill-order=msb

seems to have be added only in 6.6.2-10, unfortunately.

For now, I use the workaround of using a second image file (containing all black pixels), instead of

Code: Select all

-size 3840x2160 xc:black
