I post in this section, but I'm not sure this is the right place for documentation issues.
Anyway:
On
https://www.imagemagick.org/Usage/compose/#geometry:
Layer Canvas/Page Offsets
The composition of Layered Images use a very different philosophy. All the images (as many as you like) are treated equally in the order given. They all have a "-page" or
Page Offset that position each image's top-left corner relative to a virtual canvas 'origin' (the default offset) but without gravity.
To process multiple images a new background image is generated using the current "-background" color with a size that is dependent on the operation being performed. This is assumed to be the 'destination' image (canvas). ALL the images are composited onto this new canvas one at a time in sequence.
The link to
https://www.imagemagick.org/Usage/basic/#page seems to be broken

Anthony wrote the Usage pages. The ImageMagick developers cannot fix the problem. Hopefully, Anthony will see this and apply a patch.

Thank you for the reply @magick.
I regularly read the "Usage" pages since many years--and never realized they were maintained by only one person outside of the main project!
I will directly contact Anthony by mail since I spot another broken link.
