v0.9.2 - 2019-01-07

Changed

• Most commonly used objects have been imported into the top level namespace.
  This means that it is now possible to write code like the following.

     import stylo as st

     black = st.FillColor()
     circle = st.Circle(fill=True)

     image = st.SimpleImage(circle, black)

• The way stylo has been packaged has been changed. It now comes with a couple
  of "extras". Instead of requiring dependencies for everything, the default
  installation now only contains the packages that are absolutely required to
  run stylo.

  The other dependencies have been split into a couple of extras

  • testing: The dependencies required to import items from the stylo.testing package.
  • jupyter: Dependencies required to use stylo interactively in a jupyter notebook.

v0.9.1 - 2018-12-27

There are no changes.

This was a test release to ensure that the conversion to poetry and the changes to travis are working as intended

v0.9.0 - 2018-11-11

Added

• New stylo.math module! Currently it contains a lerp
  function to do linear implementation between two values a and
  b

• New stylo.design module! This is the start of the "next level" in
  styo's API abstracting away from the lower level objects such as shapes and
  colormaps.

  • This module adds the notion of a parameter group, this is a collection of
    values that can be passed into functions as a single object using the
    dictionary unpacking syntax (**params)

    Parameter groups are defined using the define_parameter_group
    function and taking a name and a comma separated string of parameter names.
    There is also define_time_dependent_parameter_group that can be
    used to define a parameter group that depends on time.

    Currently there are two pre-defined paramters groups, Position and
    Trajectory. They both combine the x and y values
    into a single object, with the second being the time dependent version of
    the first.

    Finally there are two built-in implementations of these parameter groups.
    StaticPosition and ParametricPosition the first takes two
    values and returns them. The second takes two functions in time and calls
    them at each supplied time value.

v0.8.0 - 2018-11-07

Added

• New Timeline system! This finally introduces explicit support for animations to stylo. 🎉

v0.7.0 - 2018-10-25

Added

• New Line shape!
• New ImplicitXY shape! Draw any curve that is implicitly defined by a
  function f(x, y)

Changed

• The Circle and Ellipse shapes now take more arguments. By
  default the shapes will now draw an outline rather than a filled in shape.

v0.6.1 - 2018-10-20

Added

• New preview keyword argument to images, set this to False if
  you don't want a matplotlib figure returned.
• New encode keyword argument to images, setting this to True
  will return a base64 encoded string representation of the image in PNG format.

Fixed

• Preview images are no longer displayed twice in jupyter notebooks
• Preview images no longer display the x and y axis numbers.

v0.6.0 - 2018-10-07

Added

Users

• New Triangle shape
• Shapes can now be inverted using the ~ operator.

Contributors

• Added new shape InvertedShape which handles the inversion of a shape
  behind the scenes.
• Tests for all the composite shapes and operators.
• More documentation on how to get involved

Changed

Users

• Shapes now have defined __repr__ methods, including shapes that have
  been combined, where a representation of a tree will be produced showing how
  the various shapes have been combined together.
• Preview images in Jupyter notebooks are now larger by default

v0.5.0 2018-09-27

Added

Users

• New Image object LayeredImage object that can now draw more
  than one object
• Added an introductory tutorial for first time users to the documentation
• Functions from the stylo.domain.transform package can now be applied
  to shapes, meaning that most images can now be made without handling domains
  directly.

Contributors

• Added a Drawable class, this allows a domain, shape and colormap to
  be treated as a single entity.
• Added a render_drawable function that takes a drawable and some
  existing image data and applies it to the data.
• Added a get_real_domain function that given a width, height and scale
  returns a RectangularDomain with appropriate aspect ratio,
  :math:(0, 0) at the centre of the image and the scale corresponding to the
  interval :math:[ymin, ymax]
• We now make use of the [scripts] section of Pipfile so
  running common commands is now easier to remember
  • pipenv run test: to run the test suite
  • pipenv run lint: to lint the codebase
  • pipenv run docs: to run a full build of the documentation
  • pipenv run docs_fast: to run a less complete but faster build of
    the documentation.

Changed

Users

• Altered SimpleImage to no longer take a domain, reducing the
  cognitive load on first time users. It now instead takes an optional
  scale variable to control the size of the domain underneath. This
  also means that the domain now automatically matches the aspect ratio of the
  image so no more distortion in non-square images.

Contributors

• The tests now take advantage of multi-core machines and should now run much
  faster
• Building the docs now takes advantage of multi-core machines and should now
  run much faster.

Fixed

Contributors

• Fixed crashes in exampledoc.py and apidoc.py for first time
  users
• Fixed issue with sed on a Mac for people running the
  devenv-setup.sh script

v0.4.2 - 2018-09-17

Added

• Image objects can now take a size keyword argument to adjust the size of the matplotlib preview plots

v0.4.1 - 2018-09-17

Fixed

• Fixed an issue with setup.py that meant most of the code wasn't published to PyPi!
