This compression (tag Compression=2) is not very popular on its own, but
a base to implement CCITT3 2D and CCITT4 compressions.
As the format has no real benefits, it is quite hard to find an app that
accepts tho encode that for you. So I used the following program that
calls `libtiff` directly:
```cpp
#include <vector>
#include <cstdlib>
#include <iostream>
#include <tiffio.h>
// An array containing 0 and 1 of length width * height.
extern std::vector<uint8_t> array;
int main() {
// From: https://stackoverflow.com/a/34257789
TIFF *image = TIFFOpen("input.tif", "w");
int const width = 400;
int const height = 300;
TIFFSetField(image, TIFFTAG_IMAGEWIDTH, width);
TIFFSetField(image, TIFFTAG_IMAGELENGTH, height);
TIFFSetField(image, TIFFTAG_PHOTOMETRIC, 0);
TIFFSetField(image, TIFFTAG_COMPRESSION, COMPRESSION_CCITTRLE);
TIFFSetField(image, TIFFTAG_BITSPERSAMPLE, 1);
TIFFSetField(image, TIFFTAG_SAMPLESPERPIXEL, 1);
TIFFSetField(image, TIFFTAG_ROWSPERSTRIP, 1);
std::vector<uint8_t> scan_line(width / 8 + 8, 0);
int count = 0;
for (int i = 0; i < height; i++) {
std::fill(scan_line.begin(), scan_line.end(), 0);
for (int x = 0; x < width; ++x) {
uint8_t eight_pixels = scan_line.at(x / 8);
eight_pixels = eight_pixels << 1;
eight_pixels |= !array.at(i * width + x);
scan_line.at(x / 8) = eight_pixels;
}
int bytes = int(width / 8.0 + 0.5);
if (TIFFWriteScanline(image, scan_line.data(), i, bytes) != 1)
std::cerr << "Something went wrong\n";
}
TIFFClose(image);
}
