Android Question Converting ARGB_565 to ARGB_8888

WebbyBoy · Oct 5, 2013

Hi,

I'm trying to create an app using Tesseract OCR. By default it only takes ARGB_8888 format pics, but my camera takes ARGB_565

Is there a way of converting this is B4A. I've tried to use the bitmapExtended libs & compress, but the output is not writing correctly (or at all).

Is there an easy way of doing this?

Have you tried this library: http://www.b4x.com/android/forum/th...xtended-safer-loadbitmapsample.19110/#content

Sorry, I'm pretty new to B4A. I see the references to the 565 set, but not how to convert it. Any chance of a cheeky example?

I think that you will need a different library.

You should create a mutable bitmap with: http://www.b4x.com/android/help/bitmapextended.html#bitmapextended_createbitmap2
Library: http://www.b4x.com/android/forum/threads/bitmapextended-library.11689/#content

You will then use a Canvas to draw the original bitmap to this one.
