There many Python libraries developed for working with PDF documents. Extracting and analyzing this data accurately is a regular task that data scientists and other professionals face. PDF format documents contain a massive volume of unstructured data. It is extensively used across enterprises, government offices, education, finance, healthcare, and other industries. Portable Document File (PDF) is the dominant document format that is popular worldwide. These sources might include CSV files, websites, PDF documents, Excel files, and many other file formats.

Current implementation for buttons only supports "link button": when clicked, it'll launch a URL specified in button properties. Interactive forms can be created and edited in Acrobat Pro for AcroForm, or in LiveCycle Designer ES for XFA forms. V0.1.5 added interactive forms element parsing, including text input, radio button, check box, link button and drop down list. "OCR B MT,Courier New,Courier,monospace" // 05 - OCR-B MT - OCR readable san-serif fixed font "OCR-A,Courier New,Courier,monospace", // 04 - OCR-A - OCR readable san-serif fixed font "QuickType Mono,Courier New,Courier,monospace", // 03 - QuickType Mono - san-serif fixed font "QuickType Condensed,Arial Narrow,Arial,Helvetica,sans-serif", // 01 - QuickType Condensed - thin sans-serif variable font "QuickType,Arial,Helvetica,sans-serif", // 00 - QuickType - sans-serif variable font It does require the client of the payload to have the same dictionary definition to make sense out of it when render the parser output on to screen. This dictionary data contract design will allow the output just reference a dictionary key, rather than the actual full definition of color or font style. Same reason to having "HLines" and "VLines" array in 'Page' object, color and style dictionary will help to reduce the size of payload when transporting the parsing object over the wire. pdf2json will always try load field attributes xml file based on file name convention (pdfFileName.pdf's field XML file must be named pdfFileName_fieldInfo.xml in the same directory). V0.4.5 added support when fields attributes information is defined in external xml file. 'TS': fontFaceId, fontSize, 1/0 for bold, 1/0 for italic.More info about 'Style Dictionary' can be found at 'Dictionary Reference' section 'S': style index from style dictionary.'R': an array of text run, each text run object has two main fields:.If a color can be found in color dictionary, 'oc' field will be added to the field as 'original color" value. 'clr': a color index in color dictionary, same 'clr' field as in 'Fill' object.'x' and 'y': relative coordinates for positioning.'Texts': an array of text blocks with position, actual text and styling information:.More info about 'color dictionary' can be found at 'Dictionary Reference' section. 'Fills': an array of rectangular area with solid color fills, same as lines, each 'fill' object has 'x', 'y' in relative coordinates for positioning, 'w' and 'h' for width and height in page unit, plus 'clr' to reference a color with index in color dictionary.PdfParser.on("pdfParser_dataReady", pdfData => is added to line object PdfParser.on("pdfParser_dataError", errData => console.error(errData.parserError) )
