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

[One]

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

There is the PixelGetColor() function. It gets it's info from the screen though, not an image file directly.

I'm not sure if it will help here, but I had some success doing graphics manipulations with AutoIT and Image Magick (an open source graphics program with lots of command line functionality).

Look in GDIPlus and search for _GDIPlus_BitmapLockBits() function.

There should bei a lot of examples here in the forum.
