Export image

The following example demonstrates how to export an image of the imported geometry and display it using matplotlib.

Import the necessary libraries

from pathlib import Path

from ansys.mechanical.core import App
from ansys.mechanical.core.examples import delete_downloads, download_file

Initialize the embedded application

# Create an instance of the App class
app = App()

# Update the global variables
app.update_globals(globals())

# Print the app to ensure it is working
print(app)

Download and import the geometry file

Download the geometry file

geometry_path = download_file("Valve.pmdb", "pymechanical", "embedding")

Import the geometry file

geometry_import = Model.GeometryImportGroup.AddGeometryImport()
geometry_import.Import(geometry_path)

Configure graphics for image export

# Set the orientation of the camera
ExtAPI.Graphics.Camera.SetSpecificViewOrientation(ViewOrientationType.Iso)

# Set the image export format
image_export_format = GraphicsImageExportFormat.PNG

# Configure the export settings for the image
settings_720p = Ansys.Mechanical.Graphics.GraphicsImageExportSettings()
settings_720p.Resolution = GraphicsResolutionType.EnhancedResolution
settings_720p.Background = GraphicsBackgroundType.White
settings_720p.Width = 1280
settings_720p.Height = 720
settings_720p.CurrentGraphicsDisplay = False

# Rotate the geometry on the Y-axis
Graphics.Camera.Rotate(180, CameraAxisType.ScreenY)

Create a function to display the image

from matplotlib import image as mpimg
from matplotlib import pyplot as plt

# Directory to save the image
output_path = Path.cwd() / "out"


def display_image(image_name) -> None:
    """Display the image using matplotlib.

    Parameters
    ----------
    image_name : str
        The name of the image file to display.
    """
    # Create the full path to the image
    image_path = output_path / image_name

    # Plot the figure and display the image
    plt.figure(figsize=(16, 9))
    plt.imshow(mpimg.imread(str(image_path)))
    plt.xticks([])
    plt.yticks([])
    plt.axis("off")
    plt.show()

Export and display the image

# Fit the geometry in the viewing area
Graphics.Camera.SetFit()

# Export the image
geometry_image = output_path / "geometry.png"
Graphics.ExportImage(str(geometry_image), image_export_format, settings_720p)

# Display the image
display_image(geometry_image.name)

Clean up the downloaded files and app

# Delete the downloaded files
delete_downloads()

# Close the app
app.close()
