| Aug 13, 2016 at 11:08 | comment | added | Semyon Pilyukov | God bless you!!!!! FILE* outptr = fopen(outfile, "w"); - thats way I could not read from it! Just fixed with FILE* outptr = fopen(outfile, "r+") and all works!!!!! | |

As I understood Zamayla, there are two ways to resize the image vertically: 1) read-and widely write infile's row n times - this one I successfully implemented in other version of resize.c 2) copy just written row of outfile (n-1) times - I guess this is more efficient way. In this code I tried to implement 2nd way, thats way I read from outfile and write to outfile, but smth wrong((( | |
