How to fix watermark position php? - php

Question

I want the watermark to be applied to a selected image, in 5 different positions, I have 3 function for these positions center, bottom_right, top_left which work with all images but i dont know how to do bottom_left, top_right. I tried but with different images the watermark disappears or appear somewhere wrong, here are the three functions that work. I need the watermark to be placed in every image the same position like responsive.
Center:
$imgs = imagecreatefromjpeg("/var/www/$f$p/$n");
// Load the logo image
$logoImage = imagecreatefrompng("$waterpath/$watername");
imagealphablending($logoImage, true);
// Get dimensions
$imageWidth = imagesx($imgs);
$imageHeight = imagesy($imgs);
$logoWidth = imagesx($logoImage);
$logoHeight = imagesy($logoImage);
// Paste the logo
imagecopy(
// destination
$imgs,
// source
$logoImage,
// destination x and y
($imageWidth - $logoWidth) / 2, ($imageHeight - $logoHeight) / 2,
// source x and y
0, 0,
// width and height of the area of the source to copy
$logoWidth, $logoHeight);
$watermark->update(array('status' => 'done'));
imagejpeg($imgs, "/var/www/$f$p/$n");
top_left:
$imgs = imagecreatefromjpeg("/var/www/$f$p/$n");
// Load the logo image
$logoImage = imagecreatefrompng("$waterpath/$watername");
imagealphablending($logoImage, true);
// Get dimensions
$imageWidth = imagesx($imgs);
$imageHeight = imagesy($imgs);
$logoWidth = imagesx($logoImage);
$logoHeight = imagesy($logoImage);
// Paste the logo
imagecopy(
// destination
$imgs,
// source
$logoImage,
// destination x and y
($imageWidth - $logoWidth) / 100, ($imageHeight - $logoHeight) / 100,
// source x and y
0, 0,
// width and height of the area of the source to copy
$logoWidth, $logoHeight);
imagejpeg($imgs, "/var/www/$f$p/$n");
bottom_right:
$imgs = imagecreatefromjpeg("/var/www/$f$p/$n");
// Load the logo image
$stamps = imagecreatefrompng("$waterpath/$watername");
// Set the margins for the stamp and get the height/width of the stamp image
$marge_right = 10;
$marge_bottom = 10;
$sx = imagesx($stamps);
$sy = imagesy($stamps);
$imageWidth = imagesx($imgs);
$imageHeight = imagesy($imgs);
// Copy the stamp image onto our photo using the margin offsets and the photo
// width to calculate positioning of the stamp.
imagecopy($imgs, $stamps, $imageWidth - $sx - $marge_right, $imageHeight - $sy - $marge_bottom, 0, 0, imagesx($stamps), imagesy($stamps));
imagejpeg($imgs, "/var/www/$f$p/$n");
These functions i tried but they dont work with all images:
bottom_left:
$imgs = imagecreatefromjpeg("/var/www/$f$p/$n");
// Load the logo image
$stamps = imagecreatefrompng("$waterpath/$watername");
// Set the margins for the stamp and get the height/width of the stamp image
$marge_right = 670;
$marge_bottom = 10;
$sx = imagesx($stamps);
$sy = imagesy($stamps);
$imageWidth = imagesx($imgs);
$imageHeight = imagesy($imgs);
// Copy the stamp image onto our photo using the margin offsets and the photo
// width to calculate positioning of the stamp.
imagecopy($imgs, $stamps, $imageWidth - $sx - $marge_right, $imageHeight - $sy - $marge_bottom, 0, 0, imagesx($stamps), imagesy($stamps));
imagejpeg($imgs, "/var/www/$f$p/$n");
top_right:
$imgs = imagecreatefromjpeg("/var/www/$f$p/$n");
// Load the logo image
$stamps = imagecreatefrompng("$waterpath/$watername");
// Set the margins for the stamp and get the height/width of the stamp image
$marge_right = 10;
$marge_bottom = 430;
$sx = imagesx($stamps);
$sy = imagesy($stamps);
$imageWidth = imagesx($imgs);
$imageHeight = imagesy($imgs);
// Copy the stamp image onto our photo using the margin offsets and the photo
// width to calculate positioning of the stamp.
imagecopy($imgs, $stamps, $imageWidth - $sx - $marge_right, $imageHeight - $sy - $marge_bottom, 0, 0, imagesx($stamps), imagesy($stamps));
imagejpeg($imgs, "/var/www/$f$p/$n");
