Public API and Backward Incompatible Changes

This section lists public API changes that were introduced in Aspose.Words for Python via .NET 24.7. It includes not only new and obsoleted public methods, but also a description of any changes in the behavior behind the scenes in Aspose.Words for Python via .NET which may affect existing code. Any behavior introduced that could be seen as regression and modifies the existing behavior is especially important and is documented here.

Added ability to automatically determine datetime format when exporting to XLSX

Implemented the ability to automatically determine the datetime format when exporting to XLSX. The new public property XlsxSaveOptions.date_time_parsing_mode can be used to enable the automatic determining.

This use case explains how to use DateTimeParsingMode:

doc = aw.Document(file_name=MY_DIR + 'Xlsx DateTime.docx')
save_options = aw.saving.XlsxSaveOptions()
# Specify using datetime format autodetection.
save_options.date_time_parsing_mode = aw.saving.XlsxDateTimeParsingMode.AUTO + 'XlsxSaveOptions.DateTimeParsingMode.xlsx', save_options=save_options)

Added ability to change the properties of ActiveX type objects

Implemented new public properties in Aspose.Words.Drawing.Ole.Forms2OleControl class: fore_color, back_color, height, width.

This use case explains how to change properties of ActiveX controls:

doc = aw.Document(file_name=MY_DIR + 'ActiveX controls.docx')
shape = doc.get_child(aw.NodeType.SHAPE, 0, True).as_shape()
ole_control = shape.ole_format.ole_control.as_forms2_ole_control()
ole_control.fore_color = aspose.pydrawing.Color.from_argb(23, 225, 53)
ole_control.back_color = aspose.pydrawing.Color.from_argb(51, 151, 244)
ole_control.height = 100.54
ole_control.width = 201.06

Added ability to control LinkExportMode in MarkdownSaveOptions

Implemented new public property link_export_mode in Aspose.Words.Saving.MarkdownSaveOptions class.

This use case explains how to change links export mode while saving to Markdown:

doc = aw.Document()
builder = aw.DocumentBuilder(doc)
builder.insert_shape(aw.drawing.ShapeType.BALLOON, 100, 100)

# Image will be written as reference:
# ![ref1]
# [ref1]: aw_ref.001.png
save_options = aw.saving.MarkdownSaveOptions()
save_options.link_export_mode = aw.saving.MarkdownLinkExportMode.REFERENCE + "", save_options)

# Image will be written as inline:
# ![](aw_inline.001.png)
save_options.link_export_mode = aw.saving.MarkdownLinkExportMode.INLINE + "", save_options)

Added ability to modify value of radio button ActiveX control

Implemented new public class Aspose.Words.Drawing.Ole.OptionButtonControl, with the following public property selected.

This use case explains how to change value of radio button ActiveX control:

doc = aw.Document(file_name=MY_DIR + 'Radio buttons.docx')
shape1 = doc.get_child(aw.NodeType.SHAPE, 0, True).as_shape()
option_button1 = shape1.ole_format.ole_control.as_option_button_control()
# Deselect selected first item.
option_button1.selected = False
shape2 = doc.get_child(aw.NodeType.SHAPE, 1, True).as_shape()
option_button2 = shape2.ole_format.ole_control.as_option_button_control()
# Select second option button.
option_button2.selected = True + 'Shape.SelectRadioControl.docx')

Added ability to set a given ActiveX checkbox to checked or unchecked

Implemented new public class Aspose.Words.Drawing.Ole.CheckBoxControl, with the following public property checked.

This use case explains how to change state of the CheckBox ActiveX control:

doc = aw.Document(file_name=MY_DIR + 'ActiveX controls.docx')
shape = doc.get_child(aw.NodeType.SHAPE, 0, True).as_shape()
check_box_control = shape.ole_format.ole_control.as_check_box_control()
check_box_control.checked = True

Added ability to set orientation and rotation of chart data labels

The new properties orientation and rotation have been added to the ChartDataLabel and ChartDataLabelCollection classes.

This use case explains how to set data label orientation and rotation:

doc = aw.Document()
builder = aw.DocumentBuilder(doc)
shape = builder.insert_chart(chart_type=aw.drawing.charts.ChartType.COLUMN, width=432, height=252)
series = shape.chart.series[0]
data_labels = series.data_labels
# Show data labels.
series.has_data_labels = True
data_labels.show_value = True
data_labels.show_category_name = True
# Define data label shape.
data_labels.format.shape_type = aw.drawing.charts.ChartShapeType.UP_ARROW
# Set data label orientation and rotation for the entire series.
data_labels.orientation = aw.drawing.ShapeTextOrientation.VERTICAL_FAR_EAST
data_labels.rotation = -45
# Change orientation and rotation of the first data label.
data_labels[0].orientation = aw.drawing.ShapeTextOrientation.HORIZONTAL
data_labels[0].rotation = 45 + 'Charts.LabelOrientationRotation.docx')
