Re: [GM-help] No filenames in gm montage

[Agustin L. <alo...@gm...>]

Thanks again but still think the doc is not quite clear as it seems like getting
the filename printed is active by default according to the examples in
the beginning of http://www.graphicsmagick.org/montage.html
(BTW are the example files downloadable? Also, a link to the actual
graphic output of each example command would be most useful)
This is also the case for i.e. the very first figure in the document
you sent has the
filenames on.
Also, from http://www.graphicsmagick.org/montage.html:
"Initially, the composite image title is placed at the top if one is
specified (refer to -fill). Next, each image is set onto the composite
image, surrounded by its border color, with its name centered just
below it."

Regarding the options:

For comment, the doc says:

 -comment <string>
annotate an image with a comment

For naive users like me, this should rather be: "embed a comment in
the image datastream" to avoid confusion

For label, the doc says:

 -label <name>
assign a label to an image

It does not say "print a the image label", so for the native user this
seems very much like comment.
