Example 1
The filled region will be external to a demarcated region, if the initial coordinates will be outside of this region.
<?php
$src621 = imagecreate(200,200);
$clr_1_621 = imagecolorallocate($src621, 255, 255, 0);
$clr_2_621 = imagecolorallocate($src621, 0, 0, 250);
$clr_4_621 = imagecolorallocate($src621, 2,2,55);
imagerectangle($src621, 100, 100, 150, 150, $clr_4_621);
imagefill($src621, 110, 110, $clr_2_621);
header("Content-Type: image/png");
imagepng ($src621);
imagedestroy($src621);
?>
Example 2
The filled region will be internal to a demarcated region, if the initial coordinates will be inside of this region.
<?php
$src622 = imagecreate(200,200);
$clr_1_622 = imagecolorallocate($src622, 255, 255, 0);
$clr_2_622 = imagecolorallocate($src622, 0, 0, 250);
$clr_4_622 = imagecolorallocate($src622, 2,2,55);
imagerectangle($src622, 100, 100, 150, 150, $clr_4_622);
imagefill($src622, 10, 10, $clr_2_622);
header("Content-Type: image/png");
imagepng ($src622);
imagedestroy($src622);
?>
