Examples

Example #1 imagedashedline() example

<?php
// Create a 100x100 image
$im = imagecreatetruecolor(100, 100);
$white = imagecolorallocate($im, 0xFF, 0xFF, 0xFF);

// Draw a vertical dashed line
imagedashedline($im, 50, 25, 50, 75, $white);

// Save the image
imagepng($im, './dashedline.png');
imagedestroy($im);
?>

The above example will output something similar to:

Example #2 Alternative to imagedashedline()

<?php
// Create a 100x100 image
$im = imagecreatetruecolor(100, 100);
$white = imagecolorallocate($im, 0xFF, 0xFF, 0xFF);

// Define our style: First 4 pixels is white and the 
// next 4 is transparent. This creates the dashed line effect
$style = Array(
                $white, 
                $white, 
                $white, 
                $white, 
                IMG_COLOR_TRANSPARENT, 
                IMG_COLOR_TRANSPARENT, 
                IMG_COLOR_TRANSPARENT, 
                IMG_COLOR_TRANSPARENT
                );

imagesetstyle($im, $style);

// Draw the dashed line
imageline($im, 50, 25, 50, 75, IMG_COLOR_STYLED);

// Save the image
imagepng($im, './imageline.png');
imagedestroy($im);
?>
