Can a classifier handle multiple documents/forms on the same page?

Question

Can a classifier handle multiple documents/forms on the same page?

When using document: azure.ai.formrecognizer.AnalyzedDocument (coming from document_analysis_client.begin_classify_document(classifier_id, document).result().documents), I noticed that there is a document.polygon field.

Is this field present in case a document of type A or B detected on a page only fills a part of the page? For example, on the first half of the page there could be a form of type A and on the second half a form of type B.

Thanks for reaching out to us, if you are asking if the analyzer can detect multiple table/ forms, the answer is yes for quick. If you can share a sample we can run it for you to make sure everything is going well.

@Anonymous I am using the samples provided. I tried putting 2 types of forms on the same page, but the example isn't great: AB_partial.pdf.

It seems that the beginning of the second form isn't detected.

result = classify_document(
    classifier_id=classifier_id,
    file_path="sample_data/merged/AB_partial.pdf"
)
result.documents

[AnalyzedDocument(doc_type=IRS-1040-D, bounding_regions=[BoundingRegion(page_number=1, polygon=[Point(x=0.0, y=0.0), Point(x=8.5, y=0.0), Point(x=8.5, y=11.0), Point(x=0.0, y=11.0)]), BoundingRegion(page_number=2, polygon=[Point(x=0.0, y=0.0), Point(x=8.5, y=0.0), Point(x=8.5, y=11.0), Point(x=0.0, y=11.0)])], spans=[DocumentSpan(offset=0, length=0)], fields={}, confidence=0.945)]

I thought that the field polygon is for the detected document (part of the page), but maybe it is the polygon of the entire page. The points for the first and second page are the same even tough the form ends early. User's image
