PHP ImagickDraw::pathLineToVerticalAbsolute() function is an inbuilt function in PHP that is used to draw a vertical line path from the current point to the target point using absolute coordinates. The target point then becomes the new current point.
Syntax:
bool ImagickDraw::pathLineToVerticalAbsolute( float $y )
Parameters: This function accepts a single parameter $y which holds the y-coordinate.
Return Value: This function returns TRUE on success.
Exceptions: This function throws ImagickException on error.
Below given programs illustrate the ImagickDraw::pathLineToVerticalAbsolute() 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(5);
// Draw a vertical line $draw ->pathStart();
$draw ->pathMoveToRelative(400, 0);
$draw ->pathLineToVerticalAbsolute(800);
$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 color $draw ->setStrokeColor( 'black' );
// Set the stroke width $draw ->setStrokeWidth(5);
// Draw lines $draw ->pathStart();
for ( $x = 0; $x < 15; $x ++) {
$draw ->pathMoveToRelative(50, 0);
if ( $x % 2) {
$draw ->pathLineToVerticalAbsolute(0);
} else {
$draw ->pathLineToVerticalAbsolute(1000);
}
} $draw ->pathFinish();
// Render the draw commands $imagick ->drawImage( $draw );
// Show the output $imagick ->setImageFormat( 'png' );
header("Content-Type: image/png"); echo $imagick ->getImageBlob();
?> |
