+
+        - **Include Page breaks**: Check this box to include distinct `PageBreak` document elements in the output, if the file type supports it.
+        - **Infer Table Structure**: Check this box to add, for each table in a PDF file, a metadata field named `text_as_html` to the output for that table's document element. This field will contain an HTML representation of the table.
+        - **Elements to Exclude**: Select the name of each available type of [document element](/ui/document-elements) to exclude from the output.

+        - **Include Coordinates**: Check this box to add, for each [document element](/ui/document-elements) in the output, a metadata field named `coordinates` to the output for that document element. This field will contain the bounding box coordinates of the document element's content on the page, as well as the bounding box's width and height in pixels.
+        - **Extract Image Block Types**: Select the name of each available type of document element to add a metadata field named `image_base64` to the output for that document element. This field will contain a Base64-encoded representation of the document element's content. A Base64-to-image decoding of this field's value will return an image representing the document element's original content.
+        - **Elements to Exclude**: Select the name of each available type of document element to exclude from the output.
