Description Dmitry Kazakov 2014-04-04 17:41:54 UTC

1) Open candleglass.exr
2) Add a BG layer
3) Save
4) Open
5) The layers are reversed

Comment 1 Dmitry Kazakov 2014-04-05 19:16:27 UTC

Seems like somewhere internally when saving, the layers get sorted alphabetically! Nonesense! :(

Git commit f979974f6f1a194060f498e9f861685a188c691d by Dmitry Kazakov.

Added support to save layer attributes and order into EXR

Now we save a special EXR string attribute 'krita_layers_info' that
stores attributes and order of the Krita layers. We cannot do it by means
of EXR itself since the EXR standard does *not* define any compositioning
or ordering rules of the containing layers. So we do it ourselves.
