This means we can write low level apis in pyton or C where blender data is passed to external C modules without having to have blender support this directly.
Example use case is to get an image pointer then use ctypes to get the image buffer and pass it to a C image processing function.
rename image.save() --> image.save_render() because it uses render settings for saving.
added image.save() which is like pressing save in the image view, saving to the images path and removing the dirty flag.
Examples.
euler = Euler(1, 2, 3)
euler.order = 'ZXY'
euler = matrix.to_euler('XZY')
Still missing rna support. this still wont give the right order, defaulting to XYZ.
eul = object.rotation_euler
split PropertyRNA off into 3 types, base type, collection and array, since array and collections needed internal checks inside almost every function its better to have the, as subclassed to the property type. This makes introspection more useful.
Also made printing of structs and properties prettier giveing type and length.
OSX 10.5 PPC kept crashing on exit. After blaming bad compiles, bad python libs
and all other reasons (almost was switching to linux!) brecht found the bad line
in python free code. There was code freeing stuff whilst it wasnt allowed to.
Mac PPC gets hug!
Dicts are converted to operator properties like this:
bpy.ops.armature.extrude_forked(TRANSFORM_OT_translate={"value":(2,0,1)})
Note that this doesn't work quite well if one operator is twice in the same macro, but that's a problem at the RNA level too. I'll have to deal with that eventually.
Fixed and completed support for returning multiple values. This includes support for returning arrays, both fixed and dynamically sized. The way this is achieved is by storing an additional int value next to the dynamic parameter in the ParameterList stack which gets passed to the C function as an additional parameter. In the case of return parameters it is duty of the C function to set this int to the correct length value for the dynamic parameter (which makes sense). Note that for the dynamic output/return parameter it is assumed the function has allocated that memory (which gets freed automatically).
Also, I cleaned the makesrna's bridge function generation code a bit and renamed PROP_RETURN to PROP_OUTPUT, which represents better the reality now that there are multiple returns. The function now to mark multiple returns (outputs) is RNA_def_function_output.
For an example, look at Action.get_frame_range in rna_action_api.c, by the way Aligorith I removed the #ifdef for this function now that there's support for returning arrays, feel free to modify (the function seems to work).
written from scratch by Daniel Salazar (zanqdo). added own modifications.
New property type
bpy.props.FloatVectorProperty(), only difference with float is it takes a 'size' argument and optional 'default' sequence of floats.
moved bpy.props.* functions out of bpy_rna.c into their own C file.
blender supports type changing for textures in a way that python doesnt.
add a new general function.
Example usage:
tex = bpy.data.textures.new("Foo")
tex.type = 'IMAGE'
tex = tex.recast_type()
Macro to give the number of users accounting for fake user.
ID_REAL_USERS(id)
Use this so you can remove a datablock if it has a fake users as well as apply transformations to it in the 3D view.
Move api function bpy.data.add_texture() --> bpy.data.textures.new()/remove()
this is too arbitrary and could break if roperty order is changed.
store the property in the operator type that is to be used for menu and enum search func's.
python function for searching operator enums on invoke. (just need dynamic python enums now)
wm.invoke_search_popup(self)
change how data is added. eg.
bpy.data.add_mesh(name) --> bpy.data.meshes.new(name)
bpy.data.remove_lamp(lamp) --> bpy.data.lamps.remove(lamp)
image and texture stil use add_* funcs
- scene.render_data.frame_path(frame=num), returns the output path for rending images of video.
- scene.render_data.file_extension, readonly attribute, gives the extension ".jpg", ".mov" etc
- player support was guessing names, use the above functions to get the actual names used, accounting for #'s replacing numbers.
from the report...
# bug 1. UV properties are not raw editable but are reported
# as RAW_TYPE_INT by RNA causing wrong conversion

# bug 2. raw update of UV coordinates crash blender (rna_access.c line 252)
mtfaces.foreach_set("uv", rawuvs)

# bug 4. It is not possible to add a vertex color layer using mesh API.
me.add_vertex_color()
# no workaround...
- fixed slice assignment.
- fix for slowdown where getting a slice would get the entire array and free it for every item in the array (malloc and free for arrays >32).
- fix for thick wrapped returning an array referencing the original pointer when coercing into a mathutils type failed.
TODO
- slice assignment currently only sypports lists.
- dimensions are ignored for multidimensional arrays.
patch from Elia Sarti, (vekoon) with some modifications mainly for the python api.
- multiple values are returned as a typle in the order that are defined.
- added support for registered types returning multiple arguments (untested).
- renamed func->ret --> func->c_ret, since this only defines what the C function returns.
bpy.types.register(MacroClass)
instead of
bpy.ops.add_macro(MacroClass)
The rest is unchanged.
Also remove some now unused code for the old registration methods (there's still some remaining).
