The ImagickDraw::pathMoveToAbsolute() function is an inbuilt function in PHP which is used to start a new sub-path at the given coordinate using absolute coordinates. The current point then becomes the specified coordinate. This function is used for setting initial coordinates before starting drawing anything.
Syntax:
bool ImagickDraw::pathMoveToAbsolute( float $x, float $y )
Parameters:This function accepts two parameters as mentioned above and described below:
- $x: It specifies the x-coordinate.
- $y: It specifies the y-coordinate.
Return Value: This function returns TRUE on success.
Exceptions: This function throws ImagickException on error.
Below given programs illustrate the ImagickDraw::pathMoveToAbsolute() function in PHP:
Program 1:
<?php // 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 stroke width $draw->setStrokeWidth(30); $draw->pathStart(); // Setting the stating point to (400, 40) $draw->pathMoveToAbsolute(400, 40); // Setting the end point to (500, 40) $draw->pathLineToHorizontalAbsolute(500); $draw->pathFinish(); // Render the draw commands $imagick->drawImage($draw); // Show the output $imagick->setImageFormat('png'); header("Content-Type: image/png"); echo $imagick->getImageBlob(); ?> |
Output:
Program 2:
<?php // 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(); $color = ['blue', 'red', 'green']; // Set the stroke width $draw->setStrokeWidth(5); // Draw lines for ($x = 0; $x < 20; $x++) { $draw->setStrokeColor($color[$x % 3]); $draw->pathStart(); // Moving to next vertical line $draw->pathMoveToAbsolute($x * 40, 0); $draw->pathLineToVerticalRelative(800); $draw->pathFinish(); } for ($x = 0; $x < 20; $x++) { $draw->setStrokeColor($color[$x % 3]); $draw->pathStart(); // Moving to next horizontal line $draw->pathMoveToAbsolute(0, $x * 40); $draw->pathLineToHorizontalRelative(800); $draw->pathFinish(); } // Render the draw commands $imagick->drawImage($draw); // Show the output $imagick->setImageFormat('png'); header("Content-Type: image/png"); echo $imagick->getImageBlob(); ?> |
