Add Ellipses to Presentations in Python

Create Ellipse

In this topic, we will introduce developers about adding ellipse shapes to their slides using Aspose.Slides for Python via .NET . Aspose.Slides for Python via .NET provides an easier set of APIs to draw different kinds of shapes with just a few lines of code. To add a simple ellipse to a selected slide of the presentation, please follow the steps below:

1. Create an instance of Presentation class
2. Obtain the reference of a slide by using its Index
3. Add an AutoShape of Ellipse type using AddAutoShape method exposed by IShapes object
4. Write the modified presentation as a PPTX file

In the example given below, we have added an ellipse to the first slide.

import aspose.slides as slides

# Instantiate Prseetation class that represents the PPTX
with slides.Presentation() as pres:
    # Get the first slide
    sld = pres.slides[0]

    # Add autoshape of ellipse type
    sld.shapes.add_auto_shape(slides.ShapeType.ELLIPSE, 50, 150, 150, 50)

    #Write the PPTX file to disk
    pres.save("EllipseShp1_out.pptx", slides.export.SaveFormat.PPTX)

Create Formatted Ellipse

To add a better formatted ellipse to a slide, please follow the steps below:

1. Create an instance of Presentation class.
2. Obtain the reference of a slide by using its Index.
3. Add an AutoShape of Ellipse type using AddAutoShape method exposed by IShapes object.
4. Set the Fill Type of the Ellipse to Solid.
5. Set the Color of the Ellipse using SolidFillColor.Color property as exposed by FillFormat object associated with the IShape object.
6. Set the Color of the lines of the Ellipse.
7. Set the Width of the lines of the Ellipse.
8. Write the modified presentation as a PPTX file.

In the example given below, we have added a formatted ellipse to the first slide of the presentation.

import aspose.slides as slides
import aspose.pydrawing as draw

# Instantiate Prseetation class that represents the PPTX
with slides.Presentation() as pres:
    # Get the first slide
    sld = pres.slides[0]

    # Add autoshape of ellipse type
    shp = sld.shapes.add_auto_shape(slides.ShapeType.ELLIPSE, 50, 150, 150, 50)

    # Apply some formatting to ellipse shape
    shp.fill_format.fill_type = slides.FillType.SOLID
    shp.fill_format.solid_fill_color.color = draw.Color.chocolate

    # Apply some formatting to the line of Ellipse
    shp.line_format.fill_format.fill_type = slides.FillType.SOLID
    shp.line_format.fill_format.solid_fill_color.color = draw.Color.black
    shp.line_format.width = 5

    #Write the PPTX file to disk
    pres.save("EllipseShp2_out.pptx", slides.export.SaveFormat.PPTX)

FAQ

How do I set the exact position and size of an ellipse with respect to the slide’s units?

Coordinates and sizes are typically specified in points. For predictable results, base your calculations on the slide size and convert required millimeters or inches to points before assigning values.

How can I place an ellipse above or below other objects (control stacking order)?

Adjust the drawing order of the object by bringing it to front or sending it to back. This lets the ellipse overlap other objects or reveal those beneath it.

How do I animate the appearance or emphasis of an ellipse?

Apply entrance, emphasis, or exit effects to the shape, and configure triggers and timing to orchestrate when and how the animation plays.
