resolution : 3840 x 2160, and this can be happened when zoom levels on max(3.0) , sample file is here sample.pdf

[argmnt]

same issue!

[argmnt]

--in pdfviewer.util; --in Constants.java file

changing line below public static float PART_SIZE = 250; to: public static float PART_SIZE = 600; worked for me!

I did not dig that much about this static field but since this is a static field, according to your pdf size resolution, you can change value of this static field before rendering PdfView !!!

---

While setting this field rendering waiting time, below part shouldn't be forgetten; As doc says: /** * The size of the rendered parts (default 256) * Tinier : a little bit slower to have the whole page rendered but more reactive. * Bigger : user will have to wait longer to have the first visual results */

Change will effect to waiting time. So What you can do is adjusting value of PART_SIZE field but for better waiting rendering time you can make a trade-off between MAXIMUM_ZOOM and PART_SIZE fields. For example; You can say this MAXIMUM_ZOOM value suits my app requirements then according to that zoom value, You can set minumum value of PART_SIZE field!

Fields: Constants.java public static float PART_SIZE public static float MAXIMUM_ZOOM = 10;

@argmnt hello.. i have edited PART_SIZE to 600 but still blur on when rendered the page. This my configuration : pdfView.fromUri(uri) .defaultPage(pageNumber) .onPageChange(this) .enableAnnotationRendering(true) .onLoad(this) .scrollHandle(new DefaultScrollHandle(this)) .spacing(10) // in dp .onPageError(this) .pageFitPolicy(FitPolicy.BOTH) .swipeHorizontal(true) .autoSpacing(true) .enableSwipe(true) .pageSnap(true) .fitEachPage(true) .pageFling(true) .load();

Have you tried higher values for PART_SIZE?

[laabroo]

@argmnt Yes i have. I edited to 600. public static float PART_SIZE = 600;

This my Sample PDF

Maybe because of bitmap config, it is RGB 565. Can you try pdfView.useBestQuality(true);

Here is update from CHANGELOG.md

2.7.0-beta.1 (2017-07-05)

• Updates PdfiumAndroid to 1.7.0 which reduces memory usage about twice and improves performance by using RGB 565 format (when not using pdfView.useBestQuality(true))

[laabroo]

I have used this line : pdfView.useBestQuality(true); but still blur. Could you try use this sample ?

@argmnt i use 3.2.0-beta.1 version.

[laabroo]

@argmnt i'm using 3.2.0-beta.1. I have add pdfview.useBestQuality(true); looks good for page 1 but for the next page still blurry.

@laabroo You need to set autospacing to False.I was having the same issue in my pdf app so i just turned off the autospacing feature and the issue was resolved.

[Hector122]

same issue! I try public static float PART_SIZE = 600; not work I try with the .autoSpacing(false) not work.

Does anyone have another possibility?
