I need to convert an image from RGB format to LMS format using matrix's and an array of double to hold the LMS values as they're created. I need to take each pixel (R, G, and B) and and multiply it by the combined matrix shown below. Any ideas? I also know that I need to convert...

Image comments
Do you know code for skipping over comments in the header of an image? I'm writing a program to read an image in, modify it, and then shoot out a new image but I can only read certain images that don't have comments in them. Here is the code that I have, but it won't work for some reason.

Convert image from RGB to LMS
I need to convert an image from RGB format to LMS format using matrix's and an array of double to hold the LMS values as they're created. I need to take each pixel (R, G, and B) and and multiply it by the combined matrix shown below. Any ideas? I also know that I need to convert the byte value: (val + 256) % 256.
{0.3811,0.5783, 0.0402}
{0.1967,0.7244, 0.0782}
{0.0241,0.1288, 0.8444}

I have to write a program in Java to read a PPM file from standard in and output put it in grayscale using PGM format to standard out. To test the program, I redirect a PPM file to standard in, and redirect to output to a file e.g. java RGBtoGray < in.ppm > out.pgm.

Need help with code for Rotating an image
I have an assignment to rotate an image. I am fairly new to programming and don't really understand how to put the code together to produce an end result of a picture being rotated. I will take any help that is offered. I have to write a program in Java to read a PPM file specified on the command line and output it to standard out with it being rotated 90 degrees. I have to use read to read in the image's binary data without a loop. Thanks!
