Work with graphics (.tif, .jpg, etc)

Recommended Posts

Hello, Guys.. Can you help me?

First, please, don't tell me something like "this question was answered many times, go searching...",

because i spend some hours in searching, found lot of interesting things, but nothing, that helped me.

I want to make CIP3 - generator from .TIF (or .JPG) file.

In my mind, programm do something like this:

First. Merge picture (virtually) to 24 columns.

Second. Calculate summ of each color (C-M-Y-K) in every column.

Last. Make CIP3 file from these results.

Maybe, first of all, resize picture for quicking process

NOW MY QUESTION: How i can check color of pixel with coordinates (x,y) in .TIF (or .JPG) file?

All other toughts i can solve by myself.

P.S.: CIP3 file used for printing press, as basic color adjusting table

P.P.S.: My primary language is Russian, so sorry for bad English :)
