I don't know why my .ppm images are missing pixels. The number of color channels should equal width * height * 3, but when I display the size of the array, I'm off by thousands of color channels. I'm using a while(istream >> character). Is there any reason why I would be missing characters? Or is this technique wrong? I attached a screen shot what the ppm looks like. |

The extraction operator >> works with formatted data only and skips whitespaces, newlines, and tab. It seems like that is why you are not getting all the characters into your array. Why don't you use the "read" method of the istream to read all the data into your array? Like this istream.read(char *s, streamsize n) where s is the pointer to your character array where the extracted characters are to be stored and n is the number of the characters to be extracted from istream. |
