问题 I'm using FontMapper.getTrueTypeFont() to find available fonts by name in pdfbox 2.0.7. This has a feature to map fonts (by name) so that if I ask for Symbol and my system only has SymbolMT it will return that as a substitute. But the default implementation doesn't map the other way. My system has Symbol installed, but if I try to get SymbolMT it returns Helvetica as the best match (which doesn't work very well). The underlying FontMapperImpl class has an addSubstitute() method that lets you

问题 I am using pdfbox and easytable https://github.com/vandeseer/easytable for creating dynamic pages which works great. But I do want header to be added in alL pages. I faced/tried below things. 1) Tablebuilder is created before writing rows so we can create a perfect tablebuilder since rows are dynamic. 2) Tried to insert header in middle while creating tablebuilder which again is not perfect since TableDrawer makes the rows to suffice according to row height Any idea/help would be appreciated.

问题 Question: With PDFBox, how can I create a link annotation with "mouse over" color effect (aka rollover / mouse hover)? It means that when I hover my mouse cursor over a link in a PDF file (without clicking it), the link changes to a different color. And if I mouse the cursor away, the link changes backs to the original color. For example: The effect that I am looking for is similar to the links at stackoverflow website. When you hover the mouse cursor over ( without clicking ) the "Ask

问题 I'm trying to do something that I know isn't 100% reliable, but I've read about it and it is my understanding that the only problem I'm facing with trying to remove certain bits of text from a PDF file is that I can't replace them. What I'm trying to do is take the contents of a PDF file, then copy that content over to another PDF file, but without a regular expression found. I have found the expressions in my PDF file, and it works. However, I can't figure out a way to remove them. Is there
