You haven't mentioned anything yet, so we cannot give you "new" ideas or anything "simpler".

Post any relevant code, and the errors you're receiving.

Here is the programme that i have found recently.It is called as Rosenfeld's parallel thinning algorithm.Can it be impelemented in C++ Builder?There's an attachment here.Hope it can be opened.I'm using C++ Builder.

You need to post more code, what you posted is merely the application entry point, nothing more.

Do you yourself know how image thinning works? If not, read up first and then come back. The code you have must have documentation somewhere. Read it.

Are you actually receiving any errors from the compiler, or during runtime? Post them (and all the code too).

Here is another thinning programme that i had tried.There's no error found but there's no effect at the output(dua.dat file).Satu.dat file is the input file consists of the original data of the image.This programme was taken from the website.Thank you.
