(yes, it should be, and yes you can open a bug report requesting that so that we don't forget about it, but this is an API change, so it will just be there for GIMP 2.10 anyway). js -><- > > And gimp_export_image() designed specifically for my task. > > According to it's sources > (https://git.gnome.org/browse/gimp/tree/libgimp/gimpexport.c) there > are quite a lot of steps and not so trivial logic that should be done > to obtain result image, and I don't want to reimplement this > functionality, I want to call gimp_export_image(). > >> >> >> >> >> On 17 June 2014 19:43, Vladimir Rutsky <rutsky.vladimir@xxxxxxxxx> wrote: >>> Hello! >>> >>> I'm trying to write export plugin for custom image format in Python. >>> >>> Looking at plugins implemented in C, e.g. gimp/plug-ins/file-bmp/bmp.c, and >>> docs (http://developer.gimp.org/api/2.0/libgimp/libgimp-gimpexport.html) >>> I see, that best and recommended way to convert user image to single layer >>> image with proper capabilities is by using gimp_export_image() function. >>> >>> How gimp_export_image() can be called from Python? >>> >>> I can't find it exported Python modules and looks like it's not accessible >>> via PDB either. >>> >>> If it's not available, can you advice proper alternative?
