Imagick::getImageTotalInkDensity
This function will return an integer, with that value being equal to the evaluated value of the IMGType Constants as defined by the ImageMagick class. When accessing them, they look like "imagick::IMGTYPE_PALETTE", but with "_VALUE" values of: undefined, bilevel, grayscale, grayscalematte, palette, palettematte, truecolor, truecolormatte, colorseparation, colorseparationmatte, and optimize. If you were to print out these values, you would have '0' for undefined, '1' for bilevel, '2' for grayscale, and so on.
For a BMP picture drawn in paint, I got back the value # 4 - Palette. For a BMP or JPEG photograph of the ocean or jungle, I got back the value # 6 - Truecolor. For an animated GIF file, I got back the value # 5 - Palette Matte. For a black-and-white JPEG drawing, I got back the value # 2 - Grayscale. These are the most common results I have gotten back with this function.
Some sample code :
<?php
// Author: holdoffhunger@gmail.com
// Imagick Type
// ---------------------------------------------
$imagick_type = new Imagick();
// Open File
// ---------------------------------------------
$file_to_grab = "image_workshop_directory/test.bmp";
$file_handle_for_viewing_image_file = fopen($file_to_grab, 'a+');
// Grab File
// ---------------------------------------------
$imagick_type->readImageFile($file_handle_for_viewing_image_file);
// Get Image Type Value
// ---------------------------------------------
$image_type = $imagick_type->getImageType();
// Interpret Image Type Value
// ---------------------------------------------
switch($image_type)

Remember, the result, if successful, is an Array, wich means you should call for example "$var[format]" if you want to know what format the file uses.
