Hi, My app is a fairly simple one that takes a print-ready Indesign or Illustrator PDF and outputs image files to multiple resolutions. I'd quite like if possible to be able to load any custom ICC profile from a specified directory or fall back on the supplied PDFBox profile.
I found a reply to this issue: https://issues.apache.org/jira/browse/PDFBOX-2681 that says "If you do have a copy of the Adobe profile, you can use it with PDFBox by creating your own subclass of PDDeviceCMYK which overrides getICCProfile and then calling PDDeviceCMYK.INSTANCE = foo, where foo is an instance of your subclass. You'll need to check the terms of the profile license first, to see what usage is permitted." I tried subclassing PDDeviceCMYK however I'm not sure how to do this properly, I thought perhaps overriding the getICCProfile() method would work however my tests PDFBox was clearly still using the built in ICC profile even when I hard coded the path to my US Web Coated SWOP V2 profile in the getICCProfile method. I don't know if it's that I called PDDeviceCMYK.instance = new MyICCClass() in the wrong place or if I didn't override enough of the original PDDDeviceCMYK class. I've tried calling the PDDeviceCMYK.instance = new MyICCClass() line just before the document loads, just after it loads and just before rendering. public ICC_Profile getICCProfile() throws IOException { String name = MainClass.properties.getProperty("profiles_dir"); // orginally hard coded the location of the US Web Coated SWOP V2 profile URL url = new URL(name); if (url == null) { throw new IOException("Error loading profile: " + name); // fall back to default PDFBox profile } ICC_Profile iccProfile; try (InputStream input = url.openStream()) { iccProfile = ICC_Profile.getInstance(input); } System.out.println("Loaded profile: " + name ); return iccProfile; } Any help would be appreciated. I can live with the slightly-off colours but if I can I'd much rather have them corrected. Thanks, D
