Freestyle Python API improvements - part 9. * Fix for wild card import statements (e.g., "from Freestyle import ") was done. Now import statements are either without using "from" or with all imported names explicitly listed. GNU GPL header blocks were added to Python programs. Additional code clean-up was also made. * Removed freestyle_init.py and extra-lines.sml that were no longer used. 2013-02-24 23:43:40 +00:00

Updated Freestyle API modules according to the new hierarchical package structure. Additional bug fixes were also done along with the code updates: * Fix for the use of old Interface1D.pointsBegin() and .pointsEnd() method names in the definition of pyDensityAnisotropyF1D and pyViewMapGradientNormF1D. * Fix for wrong data types (int instead of bool) for: - pyChainSilhouetteGenericIterator constructor and its .orientation property in modules/freestyle/chainingiterators.py. - SpatialNoiseShader constructor in styles/external_contour_sketchy.py. - ChainSilhouetteIterator constructor in styles/multiple_parameterization.py. 2013-11-24 22:18:38 +00:00			`from freestyle.chainingiterators import ChainSilhouetteIterator`

Moved the Operators class from the 'freestyle' module to the 'freestyle.types' submodule. 2013-12-30 23:43:47 +09:00			`from freestyle.types import Operators, Stroke`

Freestyle Python API improvements - part 8. * Proper handling of keyword arguments was implemented in Operators and ContextFunctions, as well as in methods of Interface0D, Interface1D, Iterator, their subclasses, Noise and IntegrationType. * Operators' methods and functions in the ContextFunctions module were renamed from CamelCase to lower cases + underscores. Style modules were updated accordingly. * Additional code clean-up was also made. 2013-02-24 02:39:38 +00:00			`Operators.bidirectional_chain(ChainSilhouetteIterator(), NotUP1D(QuantitativeInvisibilityUP1D(0)))`
Freestyle Python API improvements - part 1. * The API syntax of StrokeVertex and StrokeAttribute was updated by means of getter/setter properties instead of class methods. Python style modules (including the Parameter Editor implementation) were updated accordingly. * Code clean-up was done for a few Python style modules, mostly by removing duplicated definitions of stroke shaders and fixing indentation. 2013-01-27 20:17:49 +00:00			`shaders_list = [`
