Example #1 imagedashedline() example
<?php// Create a 100x100 image$im = imagecreatetruecolor(100, 100);$white = imagecolorallocate($im, 0xFF, 0xFF, 0xFF);// Draw a vertical dashed lineimagedashedline($im, 50, 25, 50, 75, $white);// Save the imageimagepng($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, $style);// Draw the dashed lineimageline($im, 50, 25, 50, 75, IMG_COLOR_STYLED);// Save the imageimagepng($im, './imageline.png');imagedestroy($im);?>
