Below programs illustrate the ImagickDraw::getStrokeLineJoin() function in PHP:
Program 1:

Output:
1 // Which corresponds to imagick::LINEJOIN_MITER
Program 2:
<?php // Create a new ImagickDraw object $draw = new ImagickDraw(); // Set the stroke line join $draw->setStrokeLineJoin(3); // Get the stroke line join $lineJoin = $draw->getStrokeLineJoin(); echo $lineJoin; ?> |
Output:
3 // Which corresponds to imagick::LINEJOIN_BEVEL
Program 3:
<?php // Create a new ImagickDraw object $draw = new ImagickDraw(); // Create a new imagick object $imagick = new Imagick(); // Create a image on imagick object $imagick->newImage(800, 250, 'white'); // Create a new ImagickDraw object $draw = new ImagickDraw(); // Set the fill color $draw->setFillColor('white'); // Set the color of stroke $draw->setStrokeColor('blue'); // Set the stroke width $draw->setStrokeWidth(4); // Set the font size $draw->setFontSize(25); // Set the stroke dash array $draw->setStrokeDashArray([20]); // Draw a rectangle $draw->rectangle(100, 50, 225, 175); // Annotate a text $draw->annotation(10, 220, 'The strokeLineJoin here is ' . $draw->getStrokeLineJoin()); // Set the stroke line join $draw->setStrokeLineJoin(2); // Draw a rectangle $draw->rectangle(500, 50, 625, 175); // Annotate a text $draw->annotation(400, 220, 'The strokeLineJoin here is ' . $draw->getStrokeLineJoin()); // Render the draw commands $imagick->drawImage($draw); // Show the output $imagick->setImageFormat('png'); header("Content-Type: image/png"); echo $imagick->getImageBlob(); ?> |
