Hello, recently I found bug with parsing some .pdf files. If file have symbols colored in semi-transparent color, a program just stops without any error messages. Here's code which stops silent (declaration.pdf - "unparsable" document):
let fs = require('fs'),
PDFParser = require("pdf2json");
let pdfParser = new PDFParser(this, 1);
pdfParser.on("pdfParser_dataError", errData => console.error(errData.parserError) );
pdfParser.on("pdfParser_dataReady", pdfData => {
fs.writeFile("./content.txt", pdfParser.getRawTextContent());
});
pdfParser.loadPDF("./Declaration.pdf");
So, after I tried to parse document directly with pdf2json:
node pdf2json.js "../../documents/whitepaper/47/WP_En.pdf" "../../"
And I got some errors:
Warning: Unhandled rejection: Error: JPEG error: Unsupported color mode (4 components)

In a nutshell, my solution was to comment 2 lines(832-833) in /base/core/jpg.js:
if (!this.adobe)
throw 'Unsupported color mode (4 components)';

:After that I successfully parsed my document.
So, @modesty, can you fix this or just remove?
