Create raster and fill with values
The following example is a simple case of creating a raster of 10 rows by 5 columns and filling it with random values between 1 and 6.
// example_1.cpp
#include <pronto/raster/io.h>
#include <pronto/raster/plot_raster.h>
#include <random>
namespace pr = pronto::raster;
int main()
{
auto rng = std::default_random_engine{};
auto dice = std::uniform_int_distribution<int>{ 1, 6 };
auto raster = pr::create<int>("demo.tif", 10, 5);
for (auto&& v : raster) {
v = dice(rng);
}
plot_raster(raster);
return 0;
}
Output (will vary due to random number generator):
Rows: 10, Cols: 5, Value type: int
3 1 3 6 5
2 6 6 1 2
2 6 1 1 6
1 4 5 2 5
6 2 6 2 1
3 5 4 5 6
1 4 2 3 1
2 2 6 2 1
1 1 6 1 6
1 4 5 2 3
