The ImagickDraw::pathMoveToRelative() function is an inbuilt function in PHP which is used to start a new sub-path at the given coordinate using relative coordinates. The current point then becomes the specified coordinate. This function is used for setting initial coordinates before starting drawing anything.
Syntax:
bool ImagickDraw::pathMoveToRelative( 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::pathMoveToRelative() 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, 100) $draw->pathMoveToRelative(400, 100); // Setting the end point to (500, 100) $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(); // Set the stroke width $draw->setStrokeWidth(30); $draw->setFillColor('red'); $draw->pathStart(); // Setting the stating point to (400, 100), draw a rectangle $draw->pathMoveToRelative(400, 100); $draw->pathLineToAbsolute(400, 200); $draw->pathLineToAbsolute(300, 200); $draw->pathLineToAbsolute(300, 100); $draw->pathFinish(); // Render the draw commands $imagick->drawImage($draw); // Show the output $imagick->setImageFormat('png'); header("Content-Type: image/png"); echo $imagick->getImageBlob(); ?> |
Output:
