The solution writes the image into an opened file. The file format might fail to work on certain [[OS]]es, because output might mangle control characters like LF, CR, FF, HT, VT etc. The OS might also limit the line length of a text file. In general it is a bad idea to mix binary and text output in one file. This solution uses ''stream I/O'', which should be as portable as possible.

This implementation uses a StreamWriter to write the header in text, then writes the pixel data in binary using a BinaryWriter.

Two additional imports are needed:

Saving a file is easy as a pie:

▲auto p6 = new P6Image(new FileConduit("image.ppm"));
auto write = new Writer(new FileConduit("out.ppm", FileConduit.WriteCreate));
