Counting Artifacts of a Particular Type in Python via .NET

Counting Artifacts of a Particular Type

Inspect and count pagination artifacts in a PDF document using Aspose.PDF for Python via .NET. Pagination artifacts include elements such as watermarks, backgrounds, headers, and footers that are applied to pages for layout and identification purposes. By filtering artifacts on a page and grouping them by subtype, developers can quickly analyze the document’s structure and verify the presence of specific elements.

To calculate the total count of artifacts of a particular type (for example, the total number of watermarks), use the following code:

1. Open the PDF document.
2. Filter pagination artifacts.
3. Count artifacts by subtype.
4. Print results.

import aspose.pdf as ap

def count_pagination_artifacts(path_infile):
    # Open the PDF document
    with ap.Document(path_infile) as document:
        
        # Extract pagination artifacts from the first page
        pagination_artifacts = [
            artifact for artifact in document.pages[1].artifacts
            if artifact.type == ap.Artifact.ArtifactType.PAGINATION
        ]

        # Count artifacts by subtype
        watermarks = sum(1 for artifact in pagination_artifacts 
                         if artifact.subtype == ap.Artifact.ArtifactSubtype.WATERMARK)
        backgrounds = sum(1 for artifact in pagination_artifacts 
                          if artifact.subtype == ap.Artifact.ArtifactSubtype.BACKGROUND)
        headers = sum(1 for artifact in pagination_artifacts 
                      if artifact.subtype == ap.Artifact.ArtifactSubtype.HEADER)
        footers = sum(1 for artifact in pagination_artifacts 
                      if artifact.subtype == ap.Artifact.ArtifactSubtype.FOOTER)

        # Display results
        print(f"Watermarks: {watermarks}")
        print(f"Backgrounds: {backgrounds}")
        print(f"Headers: {headers}")
        print(f"Footers: {footers}")
