PFImage

A class that provides the ability to work with color images in PF (portable floatmap image) format. NB: The format is raw binary. Support of this format is EXPERIMENTAL (!!!).

Note: This class supports indexing and assigning values ​​to specific pixels via 1D or 2D indexing, and provides PF 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 *.pfm.

Typical usage:

// create empty PF image
auto img = new PFImage; 
// load from file 					
img.load(`Lenna.pfm`);   					
// 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.pfm`);						

// new PF image, size is 10x10, all pixels black
auto img2 = new PFImage(10, 10, new RGBColor(0, 0, 0)); 
// increase two times
img2[10] = img2[10] * 2; 
// select byte order for saving (by default, little-endian, i.e BYTE_ORDER.LITTLE_ENDIAN)
img2.setOrder(BYTE_ORDER.BIG_ENDIAN);									
// save as pfm file
img2.save(`test.pfm`);
