For certain pdfs, which contain JBIG2 images, PDFbox implementation of convertToImage() method is failing silently without any exceptions or errors and finally, producing a PDF, but this time, just with blank

Get all text operators whose color is black, pdfBox

由 蓝咒 提交于 2019-12-08 13:02:24
问题 While parsing a already present pdf, I am using if(op.getOperation().equals( "TJ")) to get text operators, What I want to do is to target only the ones whose color is black(or some other specifiable color). I am unable to find a method for the same in pdfBox docs. Edit : Basically what I want to do is to keep only black colored text on the pdf, and remove/delete any other text operator which doesnt match the criteria. Can anyone share a solution ? Thanks ! 回答1: Text showing operators While

But now to avoid losing the style from the pdf I

Where can I find the exact location of the visible objects(visible on opening a document) like ColorSpaces and

PDFBox 2.0 and TTC Fonts

问题 I am trying to use PDFBox 2.0 (snapshot of 20151009) due to the availability of TTC support. But I haven't found any documentation on how to use this feature. I found a ticket here https://issues.apache.org/jira/browse/PDFBOX-2752 and I found how to load TTC file: InputStream is = MyClass.class.getResourceAsStream("font.ttc"); TrueTypeCollection coll = new TrueTypeCollection(is); but I don't know how to embed TrueTypeFont into my PDDocument. In PDFBox 1.8 I was using something similar to the
