How to set line thickness

While you can't directly set line thickness with gd, you can emulate thick lines by drawing multiple thin lines:

<?php

$im = imagecreatetruecolor(400, 300);

$c_black = imageColorAllocate($im, 0,0,0);
$c_green = imageColorAllocate($im, 46,204,64);

for ( $thick = 5; $thick > 0; $thick-- ) {
  imageline($im, 50, 50   $thick, 350, 250   $thick, $c_green);
}


imagePng($im, '/tmp/image.png');
  • imagecreatetruecolor - creates true color lib:GD image object with specified width & height
  • imageColorAllocate - creates color object to later use in image
  • imageline - draws line using given coordinates and color
  • $thick = 5 - resulting line thickness (5 in our case)
  • imagePng - saves image in PNG format to the given path

group: line

Example:

<?php

$im = imagecreatetruecolor(400, 300);

$c_black = imageColorAllocate($im, 0,0,0);
$c_green = imageColorAllocate($im, 46,204,64);

for ( $thick = 5; $thick > 0; $thick-- ) {
  imageline($im, 50, 50   $thick, 350, 250   $thick, $c_green);
}


imagePng($im, '/tmp/image.png');
