Hello,
how can I set zoom, by pinch zoom in/out?

imgsimonebiliato · Mar 16, 2016

Using:

B4X:

Dim bmp As Bitmap
bmp = pdfv.getPageBitmap(1, 1.0, 0, 0, 0, 100, 100)

the bmp isn't initialized.. So I think that, this method doesn't return a bitmap...
It is correct?

Clicking the downloadlink in Post #1?

Baris Karadeniz · May 8, 2016

I downloaded from the Post #1 but there are logs. So I thought it is changed. If it is the last, than I need to correct log: "unused variable pc" But it is used. So why there is a log???

Hi bro, I check your code and now I see is working, please test by yourselft.

Baris Karadeniz · May 12, 2016

I think I have problem with my phone. I still get same error at your example also. I will check with another phone and let you know. Thanks.

I played a bit with this lib today

The original implementation of this lib expect a file named zf in the files-folder.
when calling init this file is extracted (it is a zip file containing the .so file) to internal cache folder.
Then the native .so is loaded with system.load() from the cachefolder

I did recompile the jars, restructured it a bit and compiled it again (now including the .so file directly in the jar which now have a size of 3.7mb)...

It is working showing a onepage pdf with a high height of the page (around 9 meters) pdf in my example now...

Nice lib, @icefairy333 !

hi
i am using this library , it is working fine once but when i open activity again it got crashed. do't know why, can any budy help

Mashiane · Jul 12, 2017

Funny one, the lib works with the attached pdf file but not with my own ones. On a funny note, the name "amageza" on the example test pdf in my language which is Xhosa means "Mad People", lol! I tell you Xhosa people wouldn't do business with this person!!! ha ha ha.
