I have multi tif image (multiple page tiff image having more than one page included in single image).

I want to read this tif image using PHP since I need to edit certain portions of image using php library.

Can anyone guide for steps to achieve this?

Thanks in advance,

You need to extract them before you can work on it. Use imagemagick:

convert multi.tif file%d.tif

When you finish you can merge them with this command:

convert file0.tif file1.tif file2.tif -adjoin multi.tif

On PHP there's a library for that, IMagick: http://php.net/manual/en/book.imagick.php but I prefer to work directly with ImageMagick, it spends less memory. Bye :)
