[magick-users] -compose

[Glenn Linderman]

So I was doing a book layout, putting small pages on a big page.

The idea is that page fragments, formatted to fit small page sizes 
already, or easily cropped from something containing it, would be placed 
in various spots on the big page.

Some pages are to be composed of multiple pages.  Note c004.tif and 
c005.tif below... they are both contributing to the same small page, but 
do not both contain black stuff at the same places.

All is bitonal black and white, so it seems like -compose multiply would 
let one merge these various pages, and it seems to work in some smaller 
cases I had done, where I build all the pages separately and merge them, 
but then that took lots of memory, so I thought I'd -flatten as I go.... 
but then c004.tif doesn't get included... apparently it gets overlaid by 
c005.tif, even the white parts.

Does -compose only persist for one -flatten?  I thought as a setting, it 
would persist until it was changed.
