Hi All
Sorry for basic question but i am new to this problem. I search alot but could not succeed.
I have 3x3 char array
1,1,0
0,0,0
0,1,0
when i store them in an image using libtiff library on Linux OS,left most 1 appears on 8th position and second 1 appears on 16th position.
I need them on first 2 positions as they are instead they are on 8th and 16th.
How can i convert the above array to bits from chars so that it appears as it is, when i store in image.
Thanks for help
that's because a character, or unsigned character is represented by 8 bits. I think what you're after is 11000000 (binary) = 192 (decimal).
What you have is 1,1,0 (decimal) = 00000001, 00000001, 00000000 (binary)
EDIT: you could always bit shift the value 1 into a character/unsigned character. That would be another way of achieving 11000000.

Have a look at the bit masking on the internet, it will show you on how to set and unset bits in a given btye.
