问题 Given a black and white PDF, how do I reverse the colors such that background is black and everything else is white? Adobe Reader does it ( Preferences -> Accessibility ) for viewing purposes only in the program.

How to reverse colors permanently? 回答1: You can run the following Ghostscript command: gs -o inverted.pdf \ -sDEVICE=pdfwrite \ -c "{1 exch sub}{1 exch sub}{1 exch sub}{1 exch sub

问题 I have tried to use Apache FOP to convert HTML to PDF. ( HTML -->XHTML--> XSL-FO --> PDF). I used the xhtml2fo.xsl from Antenna House for the xhtml --> XSL-FO conversion. It works for simple html files. It does not work for html files with styling ( via embedded css or by style attribute). A PDF is created but completely unformatted. I am trying to convert HTML file where I do not have much control over the styling/content. Creating an xslt for each html is not practical in my use-case.
