v 1.9

  • Added show_color_triple function as a convenience for displaying (red, green, blue) triplets without breaking them out into components
  • Added Color wrapper for colors in the colors and fui_colors dictionaries to support .red, .green, and .blue attribute access for the component colors

v 1.8

  • Add clear function
  • Use clear_output(wait=True) to avoid flickering in animations

v 1.7

  • Added show_image and save_image for embedding an image in the Notebook and saving an image to a file, respectively.

v 1.6

  • Added post_to_web and from_web methods for for communication with ipythonblocks.org.
  • Added a display_time keyword to the flash() method.
  • Changed the animate property to a method so that it can take a stop_time keyword to control the amount of time between loop steps.
  • Fixed an error with improperly set attributes on views of grids.
  • Fixed negative indexing in lower-left origin ImageGrids.
  • Fixed an error that allowed too-large indices in lower-left origin ImageGrids.
  • Allow color assignment from Blocks/Pixels, not just tuples. (Thanks @wolever.)

v 1.5

  • Fixed an issue with an index of -1 in a 2D slice.
  • Fixed a display issue with show_color on Firefox.
  • Added a dictionary of HTML colors called colors

v 1.4

  • The lines between cells can be toggled on and off. Turning the lines off can sometimes improve the aesthetics of grids, especially at small block sizes.

  • Added a show_color function that just shows a stripe of a given color.
  • Added an embed_colorpicker function that embeds the website http://www.colorpicker.com/ in the Notebook.

v 1.3

  • Added BlockGrid.animate attribute and BlockGrid.flash method to facilitate animation of grid changes in the Notebook.
  • Added Pixel and ImageGrid subclasses that behave more like image manipulation libraries.
  • Added cell titles so hover the mouse over a block displays the block index and color.

v 1.2

  • Block.row and Block.col are now set by their containing BlockGrid at the time the Block is returned to the user. This means that while iterating over a subgrid the first Block will have coordinates (0, 0).
  • Getting a single row from a BlockGrid will return a new BlockGrid
  • Raise a TypeError when indexing a BlockGrid with a length one tuple
  • Added a Block.colors property

v 1.1.1

  • Convert assigned floating point numbers to integers for HTML compatibility
  • Added the ability to change the size of individual blocks

v 1.1

  • Python 3 support (thanks to Thomas Kluyver)
  • for block in grid style iteration
  • Block now has an HTML representation for displaying individual blocks
  • __str__ methods on Block and BlockGrid
