Below programs illustrate the GmagickDraw::point() function in PHP:
Program 1:
<?php // Create a GmagickDraw object $draw = new GmagickDraw();
// Set the color $draw ->setFillColor( 'Green' );
// Set the width and height of image $draw ->setStrokeWidth(1170);
$draw ->setFontSize(72);
// Use loop to draw 10000 points in given area for ( $x = 0; $x < 10000; $x ++) {
$draw ->point(rand(0, 500), rand(0, 500));
} $gmagick = new Gmagick();
$gmagick ->newImage(500, 500, 'White' );
$gmagick ->setImageFormat( "png" );
// Use of drawimage function $gmagick ->drawImage( $draw );
// Display the output image header( "Content-Type: image/png" );
echo $gmagick ->getImageBlob();
?> |
Output:
Program 2:
<?php // Create a GmagickDraw object $draw = new ImagickDraw();
// Set the color // Set the width and height of image $draw ->setStrokeWidth(7000);
$draw ->setFontSize(72);
// Function to draw point for ( $x = 0; $x < 10000; $x ++) {
$draw ->setFillColor( 'green' );
$draw ->point(rand(0, 900), rand(0, 500));
} $draw ->setFontSize(40);
$gmagick = new Imagick();
$gmagick ->newImage(900, 500, 'White' );
$gmagick ->setImageFormat( "png" );
// Annotate image $gmagick ->annotateImage( $draw , 5, 120, 0,
'GeeksforGeeks: A computer science portal' );
$gmagick ->annotateImage( $draw , 5, 220, 0,
'sarthak_ishu11' );
// Use of drawimage function $gmagick ->drawImage( $draw );
// Display the output image header( "Content-Type: image/png" );
echo $gmagick ->getImageBlob();
