lonelypluto / pdfviewerdemo Goto Github PK

该怎么解决呢?

就是点击文档，输入一段文字。然后插入到pdf的文档中去

请问下如何禁掉pdf的双指放大功能？或者有什么方法获取画笔划线的轨迹坐标点吗需要用来保存下来

java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.lonelypluto.pdfviewerdemo-NESEBDxYYHYT985OnRiwkA==/base.apk"],nativeLibraryDirectories=[/data/app/com.lonelypluto.pdfviewerdemo-NESEBDxYYHYT985OnRiwkA==/lib/arm64, /system/lib64]]] couldn't find "libmupdf_java.so"

提示图片插入成功但是文件没有做任何修改， 而且还不能滑动屏幕

can u update your code there is so many errors if u open in new android studio grade issue and much more, permissions issue also

muPDFReaderView.setScaleX(2.5f);
muPDFReaderView.setScaleY(1f);
我设置这两个属性如果横批太大了有些看不到

我的需求是要把高亮和划线的内容保存到一个列表,下次点击列表就能到达标注的位置,

作者怎么不维护了？

hi!!!
I wanna apply bitmap of pdf page , I m using library for sticker I have bitmap I even have position also but don't know how to apply on pdf page, can anyone help with it

插入图片保存不了

直接下载你这个demo跑起来,正常打开PDF文件,然后插入图片,点击保存,提示"图片插入成功",可以看到PDF已经保存了,但是打开保存的PDF文件,没有看到有插入的图片呢,请问这个该怎么解决呢?

你好，大佬

我想使用您的库封装一个Flutter插件（只支持Android端），由于在Flutter端做了多文件切换操作，所以在Android的视图中使用了Fragement来显示不同的文件

部分代码如下：
`MupdfViewFragment oldPdfFragment;
// 打开pdf
public void createPDF(String filePath) {

    MupdfViewFragment fragment = MupdfViewFragment.newInstance(filePath, isHorizontalScrolling);

    fragment.setCallBack((mupdfreaderview, pdfCore) -> {
        muPDFCore = pdfCore;
        muPdfreaderview = mupdfreaderview;
    });

    fragment.setActivity(activity);

    if (oldPdfFragment == null) {
        activity.getFragmentManager().beginTransaction().add(R.id.content, fragment).show(fragment).commit();
    } else {
        activity.getFragmentManager().beginTransaction().remove(oldPdfFragment).add(R.id.content, fragment).show(fragment).commit();
    }

    oldPdfFragment = fragment;
}`

做了一半后发现，每次打开不同文件后，第一页的渲染尺寸都为 屏幕宽度*屏幕宽度，但是第二页的渲染尺寸都为正常

页面的UI组件结构为：

多次测试后发现，如果我反复打开同一个文件，会出现第一页的UI尺寸正常的情况

期望大佬能和我交流一下

QQ / Email：994792647

您好，请问so文件是基于MuPDF的那个版本开发的？能否提供编译so文件的源码？

arm64-v8a的so文件能补上吗

编译so的c源码是否可以给一份，最近刚在学这东西

大佬，提示不能打开该文件，请问是so文件支持的cpu不对吗？

请问标注过成功，标注错误，可以撤回吗？

能给我联系方式吗？有偿！

首先感谢你提供了这个公开库，正发愁不知道怎么使用mupdf呢。现在使用了最新的1.0.6版本，发现在进行添加批注的时候，在正常展示和放大展示两种状态下，画笔的粗细设置一样，但是将批注保存后，显示的批注粗细不一样。
经过检查发现是由于你在pageview类中的569行进行了放大处理，在保存的时候造成笔迹变粗，我在自己保存的地方根据缩放倍数进行了相除，保存变得正常

我做了哪些努力

在真机中正常
通过搜索引擎查出是仅支持CPU/ABI为armeabi-v7a的设备，
但是在

$ git clone git://git.ghostscript.com/mupdf-android-viewer.git

这个项目下是可以跑x86模拟器的。

请问https://github.com/joniks/Android-MuPDF这个库和官方库的主要区别或者说做了哪些改变吗❓

作者您好，请问可以实现像这样的效果吗？muPDFReaderView.setBackgroundColor(Color.parseColor("#666666"));无法改变页面中间的背景颜色

求一份mupdf的C源码，我打包官方的最新源码下来不适用这个项目，native方法找不到啥的。我正在尝试用各种方法希望能用这个项目显示出这个特殊的字体。

直接设置 scalex 和scaley 放大是放大了, 但是很模糊 请问有人碰到过这个问题吗

大佬，我显示pdf，第一个页面。很大的几率，返回的宽高不对，导致图片变形了，这个怎么改咯
