[java_bond]

hi every one
how can I compare two images pixel by pixel

[masijade]

Load them both to BufferedImages, then check out that class for varying methods to use, such as getRGB.

[java_bond]

actually i want to compare them by character by character
is it possible?

[masijade]

Google OCR, maybe?

[java_bond]

I ve tried it also
but i got OCR which work for only images which having white background and black foreground.
It just marked the data from image,like where data ve been found on an image
by using this OCR i ve done one thing , I convert color full image into binary form for extracting the position of data on an image

but now i want to check or make that data into editable form

is t possible?
plz help me

Just about everything is possible. It is only degrees of difficulty and degrees of effeciency that determine whether it is worthwhile or not. That is for you to decide. Now, if you are looking for a "simple" solution, the answer is probably no. I know of none, then again, I don't do this, either, so ... Or if you are looking for code, sorry, look somewhere else.

okay
at least give some idea or some sort of algorithm to do
