Extract Text from PDFs ​

Overview ​

To extract text content from a PDF document.

Note ​

• When we use the CPDFConverterTextToJson class to access the content streams from a PDF document, we are often faced with fragmented data. For example, let us say that we are attempting to extract a sentence that says "This is a sample sentence." from a PDF document. You may end up retrieving parts of it as separate content streams like "This" and "is a sample sentence.". This occurs because text objects in PDFs are not always cleanly organized into words sentences, or paragraphs. When OCR is unenabled, the CPDFConverterTextToJson class will return Text objects exactly as they are defined in the PDF page content streams.

Sample ​

Full sample code which illustrates the text extraction capabilities.

val cPDFConvert = CPDFConverterTextToJson(context, uri, "")

val params = CPDFConvertTextToJsonOptions()

val result: ConvertError = cPDFConvert.convert(outputDir, outputFilenameNoSuffix, params, pageArrays, 
onHandle = onHandleCal, 
onProgress = onProgressCal, 
onPost = onPostCal)
