Currently none of these options are supported :( May be some of them can be done via TeX settings, but all TeX macros are done by Martin Budaj, so he needs to say. I will add these features to the TODO list. Regards, S. Quoting Bruce Mutton <bruce.mutton@paradise.net.nz>:
Is it possible to scale images inserted into the layout, short of saving the original file to a different resolution before using it with Therion?
Is it possible to put the image on the bottom layer, as it is with grids and surfaces?
Change its opacity?
(For example an indistinct image could be used as a watermark or background to the finished cave map drawing -not that I really want to do this, mainly just to get better control of the image)
layout
map-image 0 0 sw ./sketches/logo.jpg /
#image bottom
#image-scale 2x /
#image-opacity 5 # in case the image is on top of the cave for instance
endlayout
Thanks
Bruce
PS: The continuous code grid works fine. Thanks Stacho
