The ImagickDraw::pathCurveToSmoothAbsolute() function is an inbuilt function in PHP which is used to draw a cubic Bezier curve from the current point to (x, y) using absolute coordinates.
Syntax:
bool ImagickDraw::pathCurveToSmoothAbsolute ( float $x2, float $y2, float $x, float $y )
Parameters: This function accepts four parameters as mentioned above and described below:
- $x2: It specifies the x-coordinate of the second control point.
- $y2: It specifies the y-coordinate of the second control point.
- $x: It specifies the x-coordinate of the ending point.
- $y: It specifies the y-coordinate of the ending point.
Return Value: This function returns TRUE on success.
Exceptions: This function throws ImagickException on error.
Below given programs illustrate the ImagickDraw::pathCurveToSmoothAbsolute() function in PHP:
Program 1:
<?php // Create a new imagick object $imagick = new Imagick();
// Create a image on imagick object $imagick ->newImage(800, 250, 'black' );
// Create a new ImagickDraw object $draw = new ImagickDraw();
$draw ->setFillColor( 'blue' );
// Set the stroke color $draw ->setStrokeColor( 'white' );
// Draw curves to Quadratic Bezier Relative (with pathClose()) $draw ->pathStart();
$draw ->pathCurveToSmoothAbsolute(50, 250, 1900, 20);
$draw ->pathClose();
$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, 'black' );
// Create a new ImagickDraw object $draw = new ImagickDraw();
$draw ->setFillColor( 'blue' );
// Set the stroke color $draw ->setStrokeColor( 'white' );
// Draw curves to Quadratic Bezier Relative (without pathClose()) $draw ->pathStart();
$draw ->pathCurveToSmoothAbsolute(150, 250, 800, 250);
$draw ->pathFinish();
// Render the draw commands $imagick ->drawImage( $draw );
// Show the output $imagick ->setImageFormat( 'png' );
header( "Content-Type: image/png" );
echo $imagick ->getImageBlob();
?> |
