Imagick Functions page: 17

Roll image

Offsets an image as defined by x and y.

Roll image example
$im = new Imagick($input);
$im->rollImage( 20, 50 );
$im->writeImage('rollImage.jpg'); 
$im->destroy();

Rotate image

Rotates an image the specified number of degrees.

Rotate image example
$im = new Imagick($input);
$im->rotateImage( new ImagickPixel('none'), 7 );
$im->trimImage ( 0 );
$im->resetImagePage( '216x174+0+0' );
$im->writeImage('rotateImage.png'); 
$im->destroy();

( Empty triangles left over from rotating the image are filled with the background color. )

Round corners

Rounds image corners.

Round corners example
$im = new Imagick($input); 
$im->roundCorners(10, 10);
$im->writeImage( "roundCorners.png" );
$im->destroy();

// Alternative method for a coloured background and save as a jpg
/*
$input = 'DSCF0848.jpg';
$size = getimagesize($input);  
$background = new Imagick();
$background->newImage($size[0], $size[1], new ImagickPixel('red'));
$image = new Imagick($input);
$image->setImageFormat("png");
$image->roundCorners(10,10);
$image->compositeImage($background, imagick::COMPOSITE_DSTATOP, 0, 0);
$image->writeImage("rounded.jpg");
*/

( The first two parameters control the amount of rounding and the three last parameters can be used to fine-tune the rounding process. )

Sample image

Scales an image to the desired dimensions with pixel sampling.

Sample image example
$im = new Imagick($input); 
$im->sampleImage(100, 100);
$im->writeImage( "sampleImage.jpg" );
$im->destroy();

( Unlike other scaling methods, this method does not introduce any additional color into the scaled image. )

Scale image

Scales the size of an image to the given dimensions.

Scale image example
$im = new Imagick($input); 
$im->scaleImage(100, 100, TRUE);
$im->writeImage( "scaleImage.jpg" );
$im->destroy();

( The other parameter will be calculated if 0 is passed as either param. )

Segment image

Analyses the image and identifies units that are simila

Separate image channel

Separates a channel from the image and returns a grayscale image.

Separate image channel example
$im = new Imagick($input); 
$im->separateImagechannel( imagick::CHANNEL_RED );
$im->writeImage( 'separateImagechannel_r.jpg' );
$im->separateImagechannel( imagick::CHANNEL_BLUE );
$im->writeImage( 'separateImagechannel_b.jpg' );
$im->separateImagechannel( imagick::CHANNEL_GREEN );
$im->writeImage( 'separateImagechannel_g.jpg' );
$im->destroy();
// Join the 3 images to display
$im = new Imagick();
$im->readImage('separateImagechannel_r.jpg' );
$im->readImage('separateImagechannel_g.jpg' );
$im->readImage('separateImagechannel_b.jpg' );
$im->resetIterator();
$appended = $im->appendImages(TRUE);
$appended->writeImage('separateImagechannel.jpg'); 
$appended->destroy();

( A channel is a particular color component of each pixel in the image. )

Sepia tone image

Applies a special effect to the image, similar to the effect achieved in a photo darkroom by sepia toning.

Sepia tone image example
$im = new Imagick($input);
$im->sepiaToneImage( 80 );
$im->writeImage('sepiaToneImage.jpg'); 
$im->destroy();

( Threshold ranges from 0 to QuantumRange and is a measure of the extent of the sepia toning. A threshold of 80 is a good starting point for a reasonable tone. )

Set background color

Sets the object's default background color.

Set color

Sets the color described by the ImagickPixel object

The colours are the same within the tolerance

$im = new Imagick($input);
$pixel = $im->getImagePixelColor( 78, 22 );
$compair = new ImagickPixel();
$compair->setColor("rgb(105,134,6)");
$output = $compair->isSimilar($pixel, 0.2);
if ( $output ) { echo "
The colours are the same within the tolerance";}
else echo "
The colours are Different";
$im->destroy();

( Sets the color described by the ImagickPixel object, with a string (e.g. "blue", "#0000ff", "rgb(0,0,255)", "cmyk(100,100,100,10)", etc.). )

Set colorspace

Sets the global colorspace value for the object.

$im = new Imagick($input);
$im->setImageColorSpace(Imagick::COLORSPACE_GRAY);
$im->sketchImage( 10, 0, 45 );
$im->writeImage('setImageColorSpace.jpg'); 
$im->destroy();

Set compression quality

Sets the object's default compression type.

Set compression quality example
$im = new Imagick($input);
$im->setCompressionQuality( 50 );
$im->writeImage('setCompressionQuality.jpg'); 
$im->destroy();

Set filename

Sets the filename before you read or write an image file.

Set first iterator

Sets the Imagick iterator to the first image.
