pdfbox

　　PDFBox是Apache下的一个操作pdf的类库。其也提供了一个命令行的工具，也提供了java调用的第三方类库。 　　下载地址: https://pdfbox.apache.org/ 　　 　　下面的实验基于JDK8+pdfbox-2.0.13.jar+pdfbox-app-2.0.13.jar(命令行工具库) 1.命令行使用 https://pdfbox.apache.org/2.0/commandline.html 　　命令行工具可以提取pdf中的图片、文本，合并pdf与拆分pdf，pdf转换为图片等操作。 1.提取图片 java -jar pdfbox-app-2.0.13.jar ExtractImages ./1.pdf 　　会在同文件夹下提取出pdf中的图片。 2.提取文字 java -jar pdfbox-app-2.0.13.jar ExtractText ./1.pdf ./text.txt 　　当然还可以指定起始页号等参数。 3.pdf转换为图片 java -jar pdfbox-app-2.0.13.jar PDFToImage ./1.pdf 　　还有许多命令行操作可以参考官网的文档，对于参数都有详细的解释。 这种方式可以封装为工具类用Runtime多线程执行操作pdf。 2.Java中作为类库使用 https://www.cnblogs.com

My use case is to have a button like so on a pdf page (really to add them to existing pages but for now I just want to see it work on anything). ---------- - Back - ---------- And what it does is just closes the current pdf page. The idea is to have multiple tabs opened and each tab is a pdf and then when you hit the "Back" button it closes the current pdf which will then focus back to the previous pdf. This is what I have been trying to use so far. // Create a new empty document try { PDDocument document = new PDDocument(); // Create a new blank page and add it to the document PDPage

I am using Apache PDFBox for configuration of PDTextField 's on a PDF document where I load Lato onto the document using: font = PDType0Font.load( @j_pd_document, java.io.FileInputStream.new('/path/to/Lato-Regular.ttf') ) # => Lato-Regular font_name = pd_default_resources.add(font).get_name # => F4 I then pass the font_name into a default_appearance_string for the PDTextField like so: j_text_field.set_default_appearance("/#{font_name} 0 Tf 0 g") # where font_name is # passed in from above The issue now occurs when I proceed to invoke setValue on the PDTextField .
