P5Image

A class that provides the ability to work with color images in P5 format. NB: The format is raw binary.

Note: This class supports indexing and assigning values ​​to specific pixels via 1D or 2D indexing, and provides P5 file loading/saving capabilities. According to the accepted convention, in the original description of the format inside the Netpbm package, the extension of these files should be *.pgm.

Typical usage:

auto img = new P5Image;  					// creating of empty image
img.load(`Lenna.pgm`);   					// load image from file `Lenna.pgm`
img[10, 10] = new RGBColor(255, 255, 255); 	// change pixel at coords (10; 10), now are white
img[10].writeln;							// get color of 11th pixel
img.save(`Lenna2.pgm`);						// save file as `Lenna2.pgm`

auto img2 = new P5Image(10, 10, new RGBColor(0, 0, 0)); // creating image of 10x10, all pixels are black
img2[10] = img2[10] * 2; 									// increasing luminance by two
img2.save(`test.pgm`);										// save as `test.pgm`
