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);
?>
