Below programs illustrate the ImagickDraw::pathStart() 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(10);
$draw ->setFillColor( 'green' );
// Start the path $draw ->pathStart();
// Draw a pattern $draw ->pathMoveToRelative(400, 200);
$draw ->pathLineToAbsolute(400, 100);
$draw ->pathLineToAbsolute(300, 200);
$draw ->pathLineToAbsolute(300, 100);
// End the path $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(10);
// Set the stroke color $draw ->setStrokeColor( 'red' );
// Set the fill color $draw ->setFillColor( 'white' );
// Start the path $draw ->pathStart();
$x = 1;
// Draw a pattern while ( $x < 10) {
$draw ->pathMoveToAbsolute( $x * 100, 0);
$draw ->pathLineToHorizontalAbsolute( $x * 100);
$draw ->pathMoveToAbsolute(0, $x * 100);
$x ++;
} $draw ->pathclose();
// End the path $draw ->pathFinish();
// Render the draw commands $imagick ->drawImage( $draw );
// Show the output $imagick ->setImageFormat( 'png' );
header( "Content-Type: image/png" );
echo $imagick ->getImageBlob();
?> |
