[GEM-dev] Importing gridflow's grid format in Gem

[Ivica Ico Bukvic]

Hi all,

I have started messing with the Gem/Gridflow interoperability. Thanks to
Mathieu Bouchard I've learned about the #pix_import and #pix_export through
which Gridflow can obtain contents of the Gem window and process them
further. Where I am at a loss is when Gridflow processes image and outputs
data in "grid" format, how to feed this back to Gem (regular pix format, or
whatever that is, is easily returned back via #pix_import, but the "grid"
format is giving me trouble)?

The reason for this need is that I would like to maintain Gem window as the
only visible window which contains both the output from Gem and Gridflow
(i.e. a 3D cube with its faces textured with the output from the Gridflow).
Attached patch sort of does that, but without any serious processing from
the Gridflow's side (other than capturing the Gem window). The problem is
with the part where the really interesting processing takes place in respect
to the Gridflow, for instance object #remap_image. This object outputs a
"grid" which I have no idea how to convert back to a format that can be
imported back to Gem. All linking with Gem objects results in errors of
various types suggesting that the two are obviously not compatible.

Any help would be greatly appreciated!

BTW, I am using Gem 0.90 and Gridflow 0.82 (on Linux).

Best wishes,

Ico
