Release History

0.6.21 (2021-09-20)

  • Fix #741 _DirPkgReader must implement .__contains__()

0.6.20 (2021-09-14)

  • Fix #206 accommodate NULL target-references in relationships.
  • Fix #223 escape image filename that appears as literal in XML.
  • Fix #517 option to display chart categories/values in reverse order.
  • Major refactoring of ancient package loading code.

0.6.19 (2021-05-17)

  • Add shapes.add_ole_object(), allowing arbitrary Excel or other binary file to be embedded as a shape on a slide. The OLE object is represented as an icon.

0.6.18 (2019-05-02)

  • .text property getters encode line-break as a vertical-tab (VT, 'v', ASCII 11/x0B). This is consistent with PowerPoint's copy/paste behavior and allows like-breaks (soft carriage-return) to be distinguished from paragraph boundary. Previously, a line-break was encoded as a newline ('n') and was not distinguishable from a paragraph boundary.

    .text properties include Shape.text, _Cell.text, TextFrame.text, _Paragraph.text and _Run.text.

  • .text property setters accept vertical-tab character and place a line-break element in that location. All other control characters other than horizontal-tab ('t') and newline ('n') in range x00-x1F are accepted and escaped with plain-text like "_x001B" for ESC (ASCII 27).

    Previously a control character other than tab or newline in an assigned string would trigger an exception related to invalid XML character.

  • add support for date axes on category charts, including writing a dateAx element for the category axis when ChartData categories are date or datetime.

BACKWARD INCOMPATIBILITIES:

Some changes were made to the boilerplate XML used to create new charts. This was done to more closely adhere to the settings PowerPoint uses when creating a chart using the UI. This may result in some appearance changes in charts after upgrading. In particular:

  • Chart.has_legend now defaults to True for Line charts.
  • Plot.vary_by_categories now defaults to False for Line charts.

0.5.0 (2014-09-13)

  • Add support for creating and manipulating bar, column, line, and pie charts
  • Major refactoring of XML layer (oxml)
  • Rationalized graphical object shape access Note backward incompatibilities below

BACKWARD INCOMPATIBILITIES:

A table is no longer treated as a shape. Rather it is a graphical object contained in a GraphicFrame shape, as are Chart and SmartArt objects.

Example:

table = shapes.add_table(...)

# becomes

graphic_frame = shapes.add_table(...)
table = graphic_frame.table

# or

table = shapes.add_table(...).table

As the enclosing shape, the id, name, shape type, position, and size are attributes of the enclosing GraphicFrame object.

The contents of a GraphicFrame shape can be identified using three available properties on a shape: has_table, has_chart, and has_smart_art. The enclosed graphical object is obtained using the properties GraphicFrame.table and GraphicFrame.chart. SmartArt is not yet supported. Accessing one of these properties on a GraphicFrame not containing the corresponding object raises an exception.
