Public API Changes
Added New Properties: ShapeElement.path_points and ShapeElement.path_types
The new path_points and path_types properties have been added to the ShapeElement class. These properties return the graphics path information from the ShapeElement.
Usage examples
import aspose.slides as slides
with slides.Presentation("shape.pptx") as pres:
auto_shape = pres.slides[0].shapes[0]
elements = auto_shape.create_shape_elements()
for element in elements:
print("Start element")
types = element.path_types
points = element.path_points
TYPE_NAMES = {
0: "Start point",
1: "LineTo point",
3: "Bezier spline point",
128: "Close subpath point",
129: "End point",
}
for p, t in zip(points, types):
print(TYPE_NAMES.get(t, "Unknown type point"), "({0}; {1})".format(p.x, p.y))
Support for the Sensitivity labels
Added New Enumeration: SensitivityLabelAssignmentType
The new SensitivityLabelAssignmentType enumeration has been added. This enumeration represents the assignment method for the sensitivity label.
| Name | Description |
|---|---|
| STANDARD | Use for any sensitivity label that was not directly applied by the user. This includes any default labels, automatically applied labels. |
| PRIVILEGED | Use for any sensitivity label that was directly applied by the user. This includes any manually applied sensitivity labels as well as recommended or mandatory labeling or any feature where the user decides which sensitivity label to apply. |
Added New Enumeration: SensitivityLabelContentType
The new SensitivityLabelContentType enumeration has been added. This enumeration represents the types of content marking that ought to be applied to a presentation document.
| Name | Description |
|---|---|
| NONE | Implies that the label is applied by default or automatically. |
| HEADER | Implies that the label was manually applied. Use for any sensitivity label that was directly applied by the user. |
| FOOTER | Implies that the label was manually applied. Use for any sensitivity label that was directly applied by the user. |
| WATERMARK | Implies that the label was manually applied. Use for any sensitivity label that was directly applied by the user. |
| ENCRYPTION | Implies that the label was manually applied. Use for any sensitivity label that was directly applied by the user. |
Added New Class: SensitivityLabel
The new SensitivityLabel class and ISensitivityLabel interface have been added. It represents the sensitivity label from Microsoft Purview Information Protection.
Added New Class: SensitivityLabelCollection
The new SensitivityLabelCollection class and ISensitivityLabelCollection interface have been added for storing the collection of sensitivity labels applied to the document.
Added New Property: Presentation.sensitivity_labels
The new sensitivity_labels property has been added to the IPresentation interface and Presentation class. It returns the collection of sensitivity labels applied to the presentation document.
Usage examples
The following code shows how to print the sensitivity labels applied to the presentation document:
import aspose.slides as slides
with slides.Presentation("SomePresentation.pptx") as pres:
sensitivity_labels = pres.sensitivity_labels
for sensitivity_label in sensitivity_labels:
print("Label ID", sensitivity_label.id, "from Azure AD site", sensitivity_label.site_id)
This code demonstrates how to add the new sensitivity label to the presentation document:
import aspose.slides as slides
import uuid
with slides.Presentation("SomePresentation.pptx") as pres:
sensitivity_labels = pres.sensitivity_labels
label_id_string = "{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}"
site_id_uuid = uuid.UUID("{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}")
label = sensitivity_labels.add(label_id_string, site_id_guid, True, slides.SensitivityLabelAssignmentType.PRIVILEGED)
label.content_mark_types.add(slides.SensitivityLabelContentType.FOOTER)
pres.save("SensitivityLabel.pptx", slides.export.SaveFormat.PPTX)
Added New Method: DocumentProperties.get_sensitivity_labels()
The new get_sensitivity_labels method has been added to the IDocumentProperties interface and DocumentProperties class. This method gets an array of sensitivity labels from the custom document properties (Microsoft Information Protection SDK Metadata).
Usage example
The following code shows how to move the sensitivity labels information from the custom document properties to the modern SensitivityLabels collection:
import aspose.slides as slides
with slides.Presentation("SomePresentation.pptx") as pres:
# Get sensitivity labels from the custom document properties
mip_sensitivity_labels = pres.document_properties.get_sensitivity_labels()
sensitivity_labels = pres.sensitivity_labels
for sensitivity_label in mip_sensitivity_labels:
# Add label to the collection
# Here you can add a check for the validity of the label information (the label is available, etc)
sensitivity_labels.add(sensitivity_label)
pres.save("SensitivityLabel.pptx", slides.export.SaveFormat.PPTX)
