P4Image

A class that provides the ability to work with color images in P4 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 P4 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 *.pbm.

Typical usage:

// create empty P4 image
auto img = new P4Image; 
// load from file 					
img.load(`Lenna.pbm`);   					
// set pixel at (10; 10) as white
img[10, 10] = new RGBColor(255, 255, 255); 	
// get 11th pixel
img[10].writeln;							
// save to file
img.save(`Lenna2.pbm`);						

// new P4 image, size is 10x10, all pixels black
auto img2 = new P4Image(10, 10, new RGBColor(0, 0, 0)); 
// increase two times
img2[10] = img2[10] * 2; 									
// save as pbm file
img2.save(`test.pbm`);
