I am writing a program to convert a large image into b/w(and similar operations),so I want to convert an image (of size say 16MB) into b/w..I cant read the entire image into memory as android memory is limited.So all I can do is to load the image Pixel by Pixel and manipulate those pixels and add the pixels to a new File – Sreekanth Karumanaghat Jul 16 '12 at 06:21

You can't, because jpeg image data isn't written pixel by pixel in the jpeg file format. But as far as I remember, jpeg encodes blocks of 8x8 pixels, so you might hold on to that...

Ok,In that case Can I retrieve that 8x8 array of pixels,(IMP: with out loading the whole image into memory) – Sreekanth Karumanaghat Jul 16 '12 at 06:31

I really have no idea whether this is possible, but you might try it out... Sorry I cannot give you more suggestions, it was just an idea. – medonja Jul 16 '12 at 09:34
