[magick-users] streaming on bilevel tif files

[Eric Pouliquen]

Hi all,

I would like to append several (20 for examples) big bilevel tif files
(48000 x 2000 for example) in a final huge bilevel tif file.

How is the fastest way to do this ?

I tried using stream command line tool, but I don't know how to use it on
bilevel files...

ex : when doing stream -depth 1 -monitor bande_mire_floyd_canvas1.tif - |
convert -depth 1 -size 48000x2000 mono:- toto.tif, I obtain a scratched
picture...

More generally, I would like to do many operations on several big bilevel
tif files, and get the result on a huge bilevel tif file. I think tream is
the best secure way to do this, isn't it ? But practically, how can I
manipulate theses files row by row ?

For you info, I'm using only command line tools, by calling them through PHP
script...

Another question : I don't really understand the difference between using
stream command, and setting Imagemagick to only use cache files and no
RAM... ?

Regards,

Eric
