imagesetinterpolation - Set the interpolation method

SYNOPSIS

       bool imagesetinterpolation (resource  $image, [int  $method = IMG_BILINEAR_FIXED])

DESCRIPTION

	Sets  the  interpolation  method,  setting  an interpolation method affects the rendering of various functions in GD, such as the imagero-
       tate(3) function.

PARAMETERS

	      o $
		image -An image resource, returned by one of the image creation functions, such as imagecreatetruecolor(3).

	      o $method
		- The interpolation method, which can be one of the following:

		     o IMG_BELL: Bell filter.

		     o IMG_BESSEL: Bessel filter.

		     o IMG_BICUBIC: Bicubic interpolation.

		     o IMG_BICUBIC_FIXED: Fixed point implementation of the bicubic interpolation.

		     o IMG_BILINEAR_FIXED: Fixed point implementation of the bilinear interpolation ( default (also on image creation)).

		     o IMG_BLACKMAN: Blackman window function.

		     o IMG_BOX: Box blur filter.

		     o IMG_BSPLINE: Spline interpolation.

		     o IMG_CATMULLROM: Cubic Hermite spline interpolation.

		     o IMG_GAUSSIAN: Gaussian function.

		     o IMG_GENERALIZED_CUBIC: Generalized cubic spline fractal interpolation.

		     o IMG_HERMITE: Hermite interpolation.

		     o IMG_HAMMING: Hamming filter.

		     o IMG_HANNING: Hanning filter.

		     o IMG_MITCHELL: Mitchell filter.

		     o IMG_POWER: Power interpolation.

		     o IMG_QUADRATIC: Inverse quadratic interpolation.

		     o IMG_SINC: Sinc function.

		     o IMG_NEAREST_NEIGHBOUR: Nearest neighbour interpolation.

		     o IMG_WEIGHTED4: Weighting filter.

		     o IMG_TRIANGLE: Triangle interpolation.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      imagesetinterpolation(3) example

	      <?php
	      // Load an image
	      $im = imagecreate(500, 500);

	      // By default interpolation is IMG_BILINEAR_FIXED, switch
	      // to use the 'Mitchell' filter:
	      imagesetinterpolation($im, IMG_MITCHELL);

	      // Continue to work with $im ...
	      ?>

NOTES

	Changing the interpolation method affects the following functions when rendering:

	      oimageaffine(3)

	      oimagerotate(3)

	      oimagescale(3)

NAME

       probe - Probe image data.

SYNOPSIS

       probe InputImage

DESCRIPTION

       This tool prints pixel values or symbolic labels at a list of user-provided image coordinates.

OPTIONS

   Global Toolkit Options (these are shared by all CMTK tools)
       --help
	    Write list of basic command line options to standard output.

       --help-all
	    Write complete list of basic and advanced command line options to standard output.

       --wiki
	    Write list of command line options to standard output in MediaWiki markup.

       --man
	    Write man page source in 'nroff' markup to standard output.

       --version
	    Write toolkit version to standard output.

       --echo
	    Write the current command line to standard output.

       --verbose-level <integer>
	    Set verbosity level.

       --verbose, -v
	    Increment verbosity level by 1 (deprecated; supported for backward compatibility).

       --threads <integer>
	    Set maximum number of parallel threads (for POSIX threads and OpenMP).

   Main Options
       --coordinates
	    Coordinate specification mode.  Supported values: "indexed", "absolute", "relative", "physical", or use one of the following:

	    --indexed
		 Use grid indexes to specify coordinates. For each dimension, the valid value range is [0,Dims-1].

	    --absolute
		 Use absolute volume coordinates. For each dimension, the valid range is [0,FOV].

	    --relative
		 Use relative volume coordinates. For each dimension, the valid range is [0,1].

	    --physical
		 Use physical volume coordinates. Each given location is transformed into image coordinates via the inverse of the images's index-
		 to-physical space matrix.

       --interpolation
	    Image interpolation method.  Supported values: "nn", "linear", "cubic", "pv", "sinc-cosine",  "sinc-hamming",  where  the  default	is
	    "nn", or use one of the following:

	    --nn Nearest neighbor interpolation [This is the default]

	    --linear
		 Trilinear interpolation

	    --cubic
		 Tricubic interpolation

	    --pv Partial volume interpolation

	    --sinc-cosine
		 Sinc interpolation with cosine window

	    --sinc-hamming
		 Sinc interpolation with Hamming window

       --sinc-window-radius <integer>
	    Window radius for Sinc interpolation [Default: 3]

       --no-reorient
	    Disable image reorientation into RAS alignment.
