Android Question Reading QRCode from PDF

[pliroforikos]

Hello
In this topic user yiankos1 created a tutorial how to scan qr code from pdf.

I created a small project that you can find bellow and works fine. Use it as you like.

But there is a small problem. It uses library pdfium which is huge. Only the small project is 22MB compiled.

From this library we need only a few commands

        Private pdf As PdfiumCore

        pdf.Initialize("pdf")

        glDoc = pdf.newDocument(File.DirInternal,"qr.pdf", 268435456,"") 'LOAD YOUR PDF FILE

        pdf.openPage(glDoc,0) ' Mandatory to do before you want to render a Page

        pdf.renderPageBitmap(glDoc,bmp,0,0,0,768dip,1024dip)

Can we use other library to convert pdf page in bitmap or reduce librarys size?

Thank you

You can make the library smaller by opening PDfium.androix.aar with 7zip and deleting jni\<all folders except of arm64-v8a>. This will make your app a 64 bit only app. If you need to support 32 bit as well then also keep the armeabi-v7a folder.
