Hi, did you consider to update support library dependency in your project? I get that due to this action this library will have support only for apps with min sdk 14, but nowadays this is enough.

Also on this years Google IO, Google announced that apps has to target at least sdk 26, and it is good practice to keep support libraries at the same version as compileSdk.

Now i have to keep support library version in my app on version 25.3.1 the same as yours, because all support libraries has to have exact same version.

I want to froms in PDF (fallible PDFs) i it possible with this library?

i want to create a library to view and sign pdf docs. can i use your library in my project

Hello,

I have a frequent crash but hard to reproduce on a specific pdf.
It is reported on Android 5, 6 and 7. Fortunaly I have a device with debug symbole.
This is the stack trace on my device:

I have display page bitmap in list, so I have to render the page like this, but have a problem that not scroll smooth

is it possible to use this library to write pdfs?

Is it possible to add this option? (i think it can be done with "FPDF_LoadMemDocument" function instead of "FPDF_LoadMemDocument").
It will be nice option in secure cases.

I would like to get all the annotations from the document. Is this possible?

Hi,

I've noticed that even in release mode, the logs of PdfiumAndroid are displayed (in your other library AndroidPdfViewer). For example:

D/jniPdfium(18482): Canvas Ver: 256
D/jniPdfium(18482): Draw Hor: 1536
D/jniPdfium(18482): Draw Ver: 2048
D/jniPdfium(18482): Start X: -1024
D/jniPdfium(18482): Start Y: -1792
D/jniPdfium(18482): Canvas Hor: 256
D/jniPdfium(18482): Canvas Ver: 256
D/jniPdfium(18482): Draw Hor: 1536
D/jniPdfium(18482): Draw Ver: 2048
D/jniPdfium(18482): Start X: -1280
D/jniPdfium(18482): Start Y: -1792

Could it be possible to remove the logs (at least for the release)?

Thank you (and thank you for the great work!)

Hi, Annotations Support will ?

Hi,

Unfortunately, I am facing below issue while opening the first page of the pdf file which is 3.7MB :

My pdf contains three pages, so how can i convert it into a single image file

I'm writing a print service to convert a pdf document page into image (bitmap). latter its bitmap will be print using esc pos command.
Here is method that I use in my print service, most code from your sample. DedetLogger just Android android.util.Log to simplify printing output.

    @Override
    protected void onPrintJobQueued(PrintJob printJob) {
        DedetLogger.Info(LOG_TAG, "onPrintJobQueued");
        printJob.start(); // to tell system printing is starting


        // https://github.com/barteksc/PdfiumAndroid
        ParcelFileDescriptor fd = printJob.getDocument().getData();
        fd.parseMode("r");

        //PdfiumCore pdfiumCore = new PdfiumCore(this);
        PdfiumCore pdfiumCore = new PdfiumCore(getApplicationContext());


        try {
            DedetLogger.Info(LOG_TAG, "Input Stream");
            InputStream fileStream = new FileInputStream(fd.getFileDescriptor());
            byte[] tmp = new byte[4];
            fileStream.read(tmp,0,4);
            //byte[] b = s.getBytes("UTF-8"); // string to byte
            String s = new String(tmp); // byte to strint
            DedetLogger.Info(LOG_TAG, "4bytes: "+s); // output: /com.dedetok.mypdf I/PS: 4bytes: %PDF i.e. file exist

            DedetLogger.Info(LOG_TAG, "#create PDFDocument object");
            com.shockwave.pdfium.PdfDocument pdfDocument = pdfiumCore.newDocument(fd); 
            // Error: /com.dedetok.mypdf W/System.err: java.io.IOException: File is empty

            int pageNum=1;
            DedetLogger.Info(LOG_TAG, "#open page 1");
            pdfiumCore.openPage(pdfDocument, pageNum);
            int width = pdfiumCore.getPageWidthPoint(pdfDocument, pageNum);
            int targetW = 57;
            int height = pdfiumCore.getPageHeightPoint(pdfDocument, pageNum);
            int targetH = height*width/57;

            DedetLogger.Info(LOG_TAG, "#render page 1 into bitmap");
            Bitmap bitmap = Bitmap.createBitmap(targetW, targetH, Bitmap.Config.ARGB_8888);

            DedetLogger.Info(LOG_TAG, "Render pdf to image done no error.");

        }

        printJob.complete(); // to tell system printing is starting
        DedetLogger.Info(LOG_TAG, "Print Job Completed");


    }
    void printBookmarksTree(List<PdfDocument.Bookmark> tree, String sep) {

Can you help me to solve it, please.

PdfiumCore pdfiumCore = new PdfiumCore(context);
   try {
       PdfDocument pdfDocument = pdfiumCore.newDocument(fd);

       pdfiumCore.openPage(pdfDocument, pageNum);

       int width = pdfiumCore.getPageWidthPoint(pdfDocument, pageNum);
       int height = pdfiumCore.getPageHeightPoint(pdfDocument, pageNum);

       // ARGB_8888 - best quality, high memory usage, higher possibility of OutOfMemoryError
       // RGB_565 - little worse quality, twice less memory usage
       Bitmap bitmap = Bitmap.createBitmap(width, height,
               Bitmap.Config.RGB_565);
       pdfiumCore.renderPageBitmap(pdfDocument, bitmap, pageNum, 0, 0,
               width, height);
       //if you need to render annotations and form fields, you can use
       //the same method above adding 'true' as last param

       pdfiumCore.closeDocument(pdfDocument); // important!

bitmap is smaller in 2,78 times then source image in pdf , why?

With the release of the Android Gradle 3 plugin and Android Studio 3 we can leverage the new build tools as well as built in C/C++ support in the editor. I did the leg work on this in a branch so I could test my own custom built versions of the libpdfium.so

Pros

• With the NDK and Cmake installed from the Sdk Manager, the JNI and thus the AAR can be built without needing the extra manual ndk-build step.
• Switching to Cmake allows the build tools to build the JNI multiple times for multiple platform levels automagically (or that's how I understand it)
• All the free IDE features work properly now

Cons

• Requires switching to API 14 minimum, however, API 9 is basically dead anyways

Would you be interested in merging this? If so I can open a PR for it.

Thanks for your help.

Best, Nick.

Hello
I'm currenty developping an application on Android with AndroidPDFViewer : https://github.com/barteksc/AndroidPdfViewer

I want to create a fonctionnality, when the user touch the screen, it put a point on the PDF at this location. After I want to mesure the distance between 2 points but it's an other problem.
I don't understand how to do this funtionnality, put a point on PDF. I found this : DImuthuUpe/AndroidPdfViewer#554
So it's possible but how ? I don't get it.
I suppose I need to create a bitmap.

Thanks for your time.

The library seems to have problems rendering certain pdf while the normal android viewer does not show the problem.

Activity which use this library finishing without Exceptions after paging heavy pdf-document (magazine) for many times (about 80 pages).

how to stop pdfiumCore.renderPageBitmap.

Hi, thanks in advance for the great effort on this project. I have a question about how to release the bitmap object cause I couldn't find any relative method in code. I wanna switch page in the ImageView, so I use PdfiumCore.openPage(pdfDocument, pageNum) with specify page number and release the old bitmap of the previous page. But I found that even I call bitmap.recycle(), the memory usage in Android Profiler keep going up. Most importantly, it's useless to force run gc().

I just want to know how to release the previous page to prevent OOM. Thanks again, hope to hear good news ASAP.

    ParcelFileDescriptor fd = open(SAMPLE_FILE);
    if (fd == null) {
        return;
    }
    pageNum = 0;
    pdfiumCore = new PdfiumCore(this);
    try {
        pdfDocument = pdfiumCore.newDocument(fd);

        pdfiumCore.openPage(pdfDocument, pageNum);

        width = pdfiumCore.getPageWidthPoint(pdfDocument, pageNum);
        height = pdfiumCore.getPageHeightPoint(pdfDocument, pageNum);
        Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.RGB_565);
        mBitmap = bitmap;
        bitmap = null;
        pdfiumCore.renderPageBitmap(pdfDocument, mBitmap, pageNum, 0, 0, width, height);

        mBigImage.setImageBitmap(mBitmap);
        //pdfiumCore.closeDocument(pdfDocument); // important!
    } catch (IOException ex) {
        ex.printStackTrace();
    }

I am currently using this library in order to render the pages of my pdf documents - it's very fast and efficient.
However, visible signatures are not rendered and therefore they are not visible on the bitmap that shows the content of a pdf page.
This is the code I use to render the pdf pages into bitmaps:

     File pdfFile = new File(pdfPath);
     ParcelFileDescriptor fileDescriptor = ParcelFileDescriptor.open(pdfFile, ParcelFileDescriptor.MODE_READ_ONLY);
      PdfiumCore pdfiumCore = new PdfiumCore(this);
      PdfDocument pdfDocument = pdfiumCore.newDocument(fileDescriptor); 
      List<Bitmap> previewList = = new ArrayList<Bitmap>();
      for(int pageNum=0; pageNum < pdfiumCore.getPageCount(pdfDocument); pageNum++){
      pdfiumCore.openPage(pdfDocument, pageNum);
      int width = pdfiumCore.getPageWidthPoint(pdfDocument, pageNum);
      int height = pdfiumCore.getPageHeightPoint(pdfDocument, pageNum);

      Bitmap bitmap = Bitmap.createBitmap(width*2, height*2, Bitmap.Config.ARGB_8888);
      pdfiumCore.renderPageBitmap(pdfDocument, bitmap, pageNum, 0, 0, width*2, height*2);

      previewList.add(bitmap);
    }

(then i set the first bitmap as the background image of a custom ImageView)

This is an example of pdf document whose signature is not correctly rendered:
pdf-test[1].pdf

Is there a way to overcome this issue?
Thanks for your time and patience,
Alberto

First cell on page rendering takes much more time than other. Is it an issue? Can it be fixed?

long startTime = System.nanoTime();
final Bitmap = proceed(task);
Log.d("RENDER", task.thumbnail + " time:" + ((System.nanoTime() - startTime) / 1000000) + "ms");

Hello,

I am working on a project where PDF library is needed as well as offline maps feature is neede. For offline maps we are using Maps.me which is based on a native library written on C++. Initially I added PdfiumAndroid through gradle and it working pretty smooth. Now, when I added maps code into this, it started crashing for armeabi-v8a, x86_64 devices as maps is only supported for armeabi-v7a and x86 devices. Then I narrowed down Pdfium support for only those two architectures and tried to build with two native libraries at the same place. But it is not able to find the actual methods in native from java. Can you please help me out that how can I build both the libraries with the support for all the devices.

Thanks in advance.

The library add ~18Mo to apk, it's a lot.
Can we reduce the size ?

Hi,
Some other native libraries(not open source) only support armeabi.
When use PdfiumAndroid together,there are merge problem.
Can PdfiumAndroid support aremabi ?

Hello again!

Original PdfRendered produce transparent Bitmaps, it is easy to change paper for reader applications. But your version of the library, produce solid while as background, no matter if I change Bitmap config to RGB_8888.

Can original PdfRenderer functionaly be restored to produce transparent background for output Bitmap's?

Have you had a chance to look into this?

You're using gnustl_static as your STL. According to this, that means users of PdfiumAndroid (including AndroidPdfViewer) can't use C++ anywhere else in their projects. I have to do just that.

If I were to build a version around c++_shared (which seems the preferred version these days), would this be something you'd merge?

How to support for richmedia content embedded inside the PDF? Any suggestion will be appreciated.

Whether link support can be extended to this richmedia functionality?

Hello!

Where can I found source code for the binary files you attached in the repo? I want to recompile it and see source (commit revs) for for three libraries: libmodpdfium.so, libmodft2.so, libmodpng.so

Or you do not have source, except link you provided?

Can the next version include mips64 support, or is this an intentional decision to reduce APK size (since mips64 is still uncommon)?

maven uploades does not contain mips64 libraries. Not like we need it, or here is a mips devices at all :)

But since you have mips32 builded, and google recently announed all apps should have 64 bit support added to all arch's, why not to add one more mips64 to to build config?

I'm using this code in my app to flatten a PDF with signatures added.

PdfiumCore pdfiumCore = new PdfiumCore(context);
ParcelFileDescriptor pfd = ParcelFileDescriptor.open(myFile, ParcelFileDescriptor.MODE_READ_ONLY);
PdfDocument pdfDocument = pdfiumCore.newDocument(pfd);

pdfiumCore.openPage(pdfDocument, page);

int width = pdfiumCore.getPageWidthPoint(pdfDocument, page);
int height = pdfiumCore.getPageHeightPoint(pdfDocument, page);

Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
pdfiumCore.renderPageBitmap(pdfDocument, bitmap, page, 0, 0, width, height);

But the resulting image created from the bitmap object won't have the signature fields drawn. Can i do something to add those signature fields to the flattening process?

Thanks
Mat

Hi,
I am using exactly same code mentioned in the readme but still getting java.lang.IllegalArgumentException: width and height must be > 0.

Thread accumulation occurs when PDF is opened many times. Each time a PDF file is switched over, a new thread is created in the current process. When PDF is closed, the thread is not closed.

i used android-pdf-view and build my apk,then size +16MB,then i traced to this project,
too big! i can't refactor this project.
give me a way, please.please!please;

How to convert path to Uri

Is it possible to create a bitmap with transparency, using renderPageBitmap?
At this moment a white background is added to the bitmap. But I want the bitmap without a background.

Including the dependency

compile 'com.github.barteksc:pdfium-android:1.4.0'

increasing the apk size upto 15.4 MB,

I just want to use this library for creating thumb from a pdf page.

Q. Is there any way to just include a specific module from this library that is used to perform only Pdf page rendering?

like google library, you just need to add specific modules, not whole library
for example, for map

compile 'com.google.android.gms:play-services-maps:8.4.0'

Hi there,
I worked on the PDFium for a year ago to create support for some of the basic features in a PDF viewer. I wonder if you plan to incorporate features link Annotation links, Table of Content and Search?

Ive added support for the text module, as you can see here: https://github.com/viezel/PdfiumAndroid/blob/78f7f67cbb4dcfdcda6f2885aeae168f8ea11c9d/src/main/jni/src/mainJNILib.cpp#L263-L389

Would that have your interest?

I am using

ParcelFileDescriptor fd = App.applicationContext.getContentResolver().openFileDescriptor(pdfUri, "r");
PdfDocument pdfDocument = pdfiumCore.newDocument(fd);

to load Pdf document.

Is there any way to save this document to any other location using Pdfium Android?

Basically I am getting uri from Google drive file, I want to save that file in my local storage.

I filed this upstream, figuring that only the original author knew how he built the shared objects checked into git, but I see that @barteksc rebuilt them after all according to git history. Sorry for the issue duplication, but it appears that upstream has gone silent anyhow.

Repost:

It would be awesome if the project had documentation for building the shared objects again from source, and where the source code that produced them lives, and also what specific version built them in order to reproduce them deterministically. Right now all we have is ELF blobs checked into git.

Was it the upstream android pdfium tree (https://android.googlesource.com/platform/external/pdfium/) that built them? If so, is it possible to document how it was done (scripting it would be even better) so it can be readily reproduced for new versions of pdfium?

Thank you!
