[BioC] get pixel coordinates interactively with EBimage

[Andrzej Oleś]

Dear Arnaud,

many thanks for your inquiry! Unfortunately, for now EBImage is not
capable of returning pixel coordinates interactively, as you would
like to. However, we are aware of this shortcoming and we hope to come
up with a solution to this in future releases.

Nevertheless, I would strongly encourage you to upgrade to the current
version of EBImage (4.0.0). It includes numerous improvements and
bugfixes, does not rely on ImageMagick anymore, and introduces a new
JavaScript image viewer in place of the old GTK-based one.

Kind regards,

Andrzej Oles
EBImage Development Team
