Imagick::thumbnailImage - Changes the size of an image

SYNOPSIS

       bool Imagick::thumbnailImage (int  $columns, int  $rows, [bool  $bestfit = false], [bool  $fill = false])

DESCRIPTION

	Changes the size of an image to the given dimensions and removes any associated profiles. The goal is to produce small, low cost thumbnail
       images suited for display on the Web. If TRUE is given as a third parameter then columns and rows parameters are used as maximums for  each
       side. Both sides will be scaled down until they match or are smaller than the parameter given for the side.

       Note

	       The  behavior  of  the parameter $bestfit changed in Imagick 3.0.0. Before this version given dimensions 400x400 an image of dimen-
	      sions 200x150 would be left untouched. In Imagick 3.0.0 and later the image would be scaled up to size 400x300 as this is the  "best
	      fit" for the given dimensions. If $bestfit parameter is used both width and height must be given.

PARAMETERS

	      o $columns
		- Image width

	      o $rows
		- Image height

	      o $bestfit
		- Whether to force maximum values

RETURN VALUES

	Returns TRUE on success.

ERRORS
/EXCEPTIONS
	Throws ImagickException on error.

EXAMPLES

       Example #1

	      Imagick.thumbnailImage(3)

	      function thumbnailImage($imagePath) {
		  $imagick = new Imagick(realpath($imagePath));
		  $imagick->setbackgroundcolor('rgb(64, 64, 64)');
		  $imagick->thumbnailImage(100, 100, true, true);
		  header("Content-Type: image/jpg");
		  echo $imagick->getImageBlob();
	      }
