I'm having issues getting this going. It's probably some issue with my Android Studio configuration, but I'm not experienced enough to know. I have a stackoverflow question on it that explains further:

https://stackoverflow.com/questions/52307125/why-doesnt-this-drawable-tinting-android-code-sample-work-out-of-the-box

I tried commenting out the offending lines... which I assumed simply setText in a textview... and now the app runs... but it doesn't seem to do what it claims... as the textview is a different color than the button... and neither one changes color or appearance as a result of being focused/clicked, etc.

I know this is the light way to implement and render .pdf, but my problem is required to render like scrollview from top to bottom instead of switching page from left to the right

The logic here is wrong. inSampleSize applies scaling to the height and the width of the bitmap,
and so the number of pixels should be scaled by the square of inSampleSize.

ImageResizer.java#L251

    // This offers some additional logic in case the image has a strange
    // aspect ratio. For example, a panorama may have a much larger
    // width than height. In these cases the total pixels might still
    // end up being too large to fit comfortably in memory, so we should
    // be more aggressive with sample down the image (=larger inSampleSize).

    long totalPixels = width * height / inSampleSize;

    // Anything more than 2x the requested pixels we'll sample down further
    final long totalReqPixelsCap = reqWidth * reqHeight * 2;

    while (totalPixels > totalReqPixelsCap) {
    inSampleSize *= 2;
    totalPixels /= 2;
    }

This causes generated bitmaps to be of much lower size than required.

        currentPage.render(bitmap, null, null, PdfRenderer.Page.RENDER_MODE_FOR_DISPLAY);

in my pdf which opened using PDFRenderer on Zoom in i cannot read the letters while i opened same pdf with other pdf viewer i can read the letters properly. I also debug and check the bitmap object and view bitmap here also on zoom in the bitmap i cannot read the letters properly.

Also in some device i am getting below crash

I have a file: pdf.txt. I rename it to: pdf.pdf
Below is my steps:

1. Open app. Open file "sample.pdf". -> OK
2. Open file "pdf.pdf" -> show Toast: "Error! file not in PDF format or corrupted"
3. Open file "sample.pdf" again. -> show Toast: "Error! file not in PDF format or corrupted"
   Now I cannot open PDF file.
   If I kill app, and open app again. File "sample.pdf" show ok. And if I open wrong file. I cannot open any files more.
   How can I resolve this issue? Thank you

Hi,

I've found a problem with the PdfRenderer, if I try to open a pdf with password I will get the SecurityException, that's alright, but if after that I try to open another pdf but this time the pdf doesn't have password, I still get the SecurityException.

This error occurs with api level <= 27

Do you know a workaround?

Thanks

I am trying to apply Tint using EffectFactory.EFFECT_TINT

below is the code I am using

        val hue = effectFactory.createEffect(EffectFactory.EFFECT_TINT)
        hue.setParameter("tint", Color.argb(255, 6, 206, 249)))

using the above code, tint is getting applied. but I tried giving alpha(0-255) values as 50, 100, 150, and 200. The intensity of the color is always the same.

"This is an odd one; it's probably a variation on Issue #82838, in which when attempting to use PdfRenderer to display Assets, the wrong Asset is used.

What seems to be the problem is that behavior of PdfRenderer to display Assets depends upon the order of entries within the .apk. If the META-INF entries are first in the .apk, then PdfRenderer won't display PDF assets at all."

When I download the sample and try to run it this is the error I get :

ClassLoader referenced unknown path: /data/app/com.example.android.pdfrendererbasic-1/lib/arm
java.io.IOException: cannot create document. Error: 3

    mPdfRenderer = new PdfRenderer(mFileDescriptor);

mPdfRenderer is always null

Android Studio is complaining about gradle-properties, as it should contain android.useAndroidX=true field. I think it's silly issue, but this repo does not have gradle.properties of it's own. Please ignore if i am wrong or guide me.

This should really get updated...

I have a PDF vector that has a region of 30 percent white, but when you load PDF into memory, it becomes pure white.

Hello,
I'm trying to use PDFRenderer to convert a PDF file generated by the Android' PrintManager
Below is this generated pdf file which seems perfectly correct.
TestPrint.pdf
And here is the code I use to convert this file in a bitmap.

    mCurrentPage = mPdfRenderer.openPage(index);

    int width = (int)(203.0 / 72.0 * mCurrentPage.getWidth() + 0.5);
    int height = (int)(203.0 / 72.0 * mCurrentPage.getHeight() + 0.5);

    Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);

    mCurrentPage.render(bitmap, null, null, PdfRenderer.Page.RENDER_MODE_FOR_PRINT);

And below is the generated Bitmap. could you please tell me where does this 80 pixels wide black border comes from?
