Specifically, to pass as third arg to Gimp.PDB.gimp_pencil(layer, 4 line).
Said argument should be GimpFloatArray according to PDBBrowser.
I create a GimpValueArray to pass args to the pdb. To create a GValue for
the third arg, I tried:
GObject.Value(Gimp.FloatArray.__gtype__, (1.0, 1.0, 1.0, 1.0)
which throws exception Expected: Boxed.
Thrown by pygobject/gi/pygi-value.c about line 556.
At line 537, it seems like it should work if G_VALUE_HOLDS(value,
G_TYPE_ARRAY) for GimpFloatArray gtype.
My understanding is that PyGObject would then create a GArray from the
Python list of floats for the value of the GValue.
My best guess is Gimp is missing GI annotations or implementation for
GimpFloatArray.
Using Gimp 2.99, I am porting GimpFu.
There might be a related problem receiving GimpInt32Array *from* Gimp (not
*to* Gimp as above.)
You don't need to do complicated things like that in Python, just use a
Python array of floats.
pdb.gimp_pencil(layer,6,[0.,0.,100.,100.,0.,200.])
