Drawing a pixel

public Image::drawPixel(int $x, int $y, $color = null): ImageInterface

Draw a single pixel at given position defined by the coordinates x and y in a given color.

Parameters

Example

// create an test image from a file
$manager = new ImageManager('imagick');
$image = $manager->make('test.png');

// draw three pixels at different positions
$image->drawPixel(12, 30, 'ff00ff');
$image->drawPixel(100, 1, [255, 255, 0]);
$image->drawPixel(200, 2, 'orange');

Drawing a rectangle

public Image::drawRectangle(int $x, int $y, ?callable $init = null): ImageInterface

Draw a colored rectangle on the current image with its top left position at the x, y coordinates. Define the overall appearance of the shape by passing a init callback as an optional parameter.

Parameters

Example

// create an test image from a file
$manager = new ImageManager('imagick');
$image = $manager->make('test.png');

// draw an orange rectangle with a border
$image->drawRectangle(10, 10, function ($rectangle) {
    $rectangle->size(180, 125); // width & height of rectangle
    $rectangle->background('orange'); // background color of rectangle
    $rectangle->border('white', 2); // border color & size of rectangle
});

Drawing ellipses

public Image::drawEllipse(int $x, int $y, ?callable $init = null): ImageInterface

Draw a colored ellipse on the current image with its center position at the x, y coordinates. Define the overall appearance of the shape by passing a init callback as an optional parameter.

Parameters

Example

// create an test image from a file
$manager = new ImageManager('imagick');
$image = $manager->make('test.png');

// draw a red ellipse with a blue border
$image->drawRectangle(10, 10, function ($ellipse) {
    $ellipse->size(180, 125); // width & height of ellipse
    $ellipse->background('f00'); // background color
    $ellipse->border('00f', 1); // border color & size
});

Drawing a circle

public Image::drawCircle(int $x, int $y, ?callable $init = null): ImageInterface

Draw a colored circle on the current image with its center position at the x, y coordinates. Define the overall appearance of the shape by passing a init callback as an optional parameter.

Parameters

Example

// create an test image from a file
$manager = new ImageManager('imagick');
$image = $manager->make('test.png');

// draw a green circle with a white border
$image->drawCircle(10, 10, function ($circle) {
    $circle->radius(150); // radius of circle in pixels
    $circle->background([0, 200, 0]); // background color
    $circle->border([255, 255, 255], 1); // border color & size
});

Drawing a line

public Image::drawLine(?callable $init = null): ImageInterface

Draw a line on the current image. Define the overall appearance of the shape by passing a init callback as an optional parameter.

Parameters

Example

// create an test image from a file
$manager = new ImageManager('imagick');
$image = $manager->make('test.png');

// draw a half transparent white line
$image->drawLine(function ($line) {
    $line->from(10, 10); // starting point of line
    $line->to(300, 100); // ending point
    $line->color([255, 255, 255, .5]); // color of line
    $line->width(5); // line width in pixels
});

Drawing a polygon

public Image::drawPolygon(?callable $init = null): ImageInterface

Draw a polygon on the current image. Define the overall appearance of the shape by passing a init callback as an optional parameter.

Parameters

Example

// create an test image from a file
$manager = new ImageManager('imagick');
$image = $manager->make('test.png');

// draw a polygon
$image->drawPolygon(function ($polygon) {
    $polygon->point(10, 10); // add point of polygon
    $polygon->point(150, 150); // add point
    $polygon->point(40, 180); // add point
    $polygon->point(60, 100); // add point
    $polygon->background('#b35187'); // background color
    $polygon->border('#ff0', 6); // border color and border width
});
