![]() PDF Producers: The Extract API is designed to extract content from files that contain text, table data, and figures.Text within annotations will not be included in the output. Annotations: Content in PDF files containing annotations such as highlights and sticky notes will be processed, but annotations that obscure text could impact output quality.Files that are secured and do not allow copying of content will not be processed. Unprotected files: The API supports files that are unprotected or where security restrictions allow copying of content.Form fields: Files containing XFA and other fillable form elements are not supported.Conditions like skewed pages, shadowing, obscured or overlapping fonts, and page resolution less than 200 DPI can all result in lower quality text output. OCR and Scan quality: The quality of text extracted from scanned files is dependent on the clarity of content in the input file.Files containing content in other Latin languages should return good results, but may have issues with non-English punctuation. Language: The API is currently optimized for English language content.For such cases, () prior to processing files again may return a successful result. Files that contain such hidden information may fail to process. Hidden Objects: PDF files that contain content that is not visible on the page like javascript, OCG (optional content groups), etc are not supported.Page Size: The API supports standard page sizes not to exceed 17.5” or less than 6” in either dimension.Rate limits: Keep request rate below 25 requests per minutes.For larger files or those with complex layouts, it is recommended to split the file into smaller sections before processing. Limits may be lower for files with multiple tables. Scanned PDFs have a limit of 150 pages or less. Number of Pages: Non-scanned PDFs have a limit of 400 pages.File size: Files up to a maximum of 100MB are supported.Reading order is determined by Bounds and path element provided in the.

So, width of an A4 page is specified to be ~= 598 units (8.3 inches x 72) when creating the PDF.Īll values reported in Extract use this 72 dpi based coordinates. As per PDF specification, 72 DPI is used when creating a PDF. If values are required in coordinates, we need a DPI value i.e. PDF pages are generally specified in inches (like A4 page is 8.3 inches x 11.7 inches). The bounds are as per PDF specification coordinates.
