How do I use MUpdf in an existing java project

由 耗尽温柔 提交于 2019-12-11 05:55:37
问题 Mupdf documentation shows me how to use the library as an application and deploy it. However, I want to suck it into an existing java project and build my application on top of it. Can this be done? If so, how do I bring just the pieces needed, into my project? 回答1: Take a look at jMuPdf. I never used it, but it seems to be active. Otherwise you will need to create Java Native Bindings (JNA or JNI). 来源： https://stackoverflow.com/questions/14445234/how-do-i-use-mupdf-in-an-existing-java

mupdf and freetype: why are fonts blurred?

由 对着背影说爱祢 提交于 2019-12-08 14:46:14
问题 I would like to know if it is mupdf's or freetype2's fault if the font is blurred (even with antialiasing). This is using the pdfdraw utility on Windows. 回答1: As I mentioned in my other answer, the glyph description is composed of lines and curves. The problem is these lines and curves cannot ensure high fidelity glyph rendering at small sizes because there is not much space to represent the glyph. In this situation a technique called font hinting is used to render readable glyphs. TrueType

How to extract embedded files from pdf using MuPDF

由 谁说胖子不能爱 提交于 2019-12-06 10:48:56
My app on iOS extracts embedded files from PDF. Now, i try to make Android app with same functionality using MuPDF .
