NOTES:
This software uses the open-source iText library.
The source .jar is included in the zip file, but more information can be found here:
https://github.com/ymasory/iText-4.2.0
.
Before the included pdfRead() function can be executed, simply run this command once:
javaaddpath('iText-4.2.0-com.itextpdf.jar')
The command can be run via console or script, but only needs to be done once.
.
This method is relatively robust, however it will not always return all the text in the document if the PDF has an unusual or complicated formatting (i.e. multiple non-fixed-width columns or excessive image captions).
