Customizing QR code after generation

[MuhammadSaad420]

I am generating QR code using zxing library...after generating, i am getting a bitmap image...can i edit QR code in the bitmap image in future instead of generating it again?

What do you mean by edit?

[MuhammadSaad420]

like generating QR code with MultiformatWriter and generating a bitmap(with default black QR pixels)....and in future Editing the bitmap(like changing the background of QR image, changing shape of QR pixel) when user wants to instead of generating the QR code again

[alexzhirkevich]

You can convert drawable to bitmap and do with it what you want. Anyway generating takes ~30ms. I guess your pixel-by-pixel editing takes a lot longer
