Check50 doesn't accept absolutely identical files. Screenshot represents example where n equals to 5.
First I made new test file that contains only one pixel - dot.bmp. Next I resized that file with my code and with staff's code. Then I checked headers of both files. According to the picture they are the same. Next step is to compare files byte-by-byte. Again, according to the screenshot files are the same.
Still check50 doesn't accept my result when n is 5.
Don't know what to do. Any help is appreciated.
ps: sorry for my english.
