So far, the most popular solution is to use a webview and use the google

PDFBox: How to “flatten” a PDF-form?

由 一世执手 提交于 2019-11-27 01:58:49
问题 How do I "flatten" a PDF-form (remove the form-field but keep the text of the field) with PDFBox? Same question was answered here: a quick way to do this, is to remove the fields from the acrofrom. For this you just need to get the document catalog, then the acroform and then remove all fields from this acroform. The graphical representation is linked with the annotation and stay in the document. So I wrote this code: import java.io.File; import java.util.ArrayList; import java.util.List;

Convert a PDF file to image

由 六月ゝ 毕业季﹏ 提交于 2019-11-27 01:21:26
问题 I wanted to convert PDF document into image. I was using Ghost4j. Problem: Ghost4J needs gsdll32.dll file at runtime, and I do not want to use the dll file. Question 1: is there any way, in ghost4j to convert image without the dll? Question 2: I found the solution in PDFBox API. org.apache.pdfbox.pdmodel.PDPagep have method convertToImage()` which converts PDF page to Image format. PDDocument doc = PDDocument.load(new File("/document.pdf")); List<PDPage>pages = doc.getDocumentCatalog()
