how to cut a picture (not cropping) with php - php

Question

I want to cut out part of the photo without stretch it.
Something like the photo I posted, cut out the red part and get photo number 2
With a width of 150px and height of 100px and cuting from top left of photo
enter image description here
I tried to do it with this code but it didn't work.
This codes separates part of the image, but does not do so from the top left of the image.
function resizejpeg($dir, $newdir, $img, $max_w, $max_h, $th_w, $th_h)
{
// set destination directory
if (!$newdir) $newdir = $dir;
// get original images width and height
list($or_w, $or_h, $or_t) = getimagesize($dir.$img);
// make sure image is a jpeg
if ($or_t == 2) {
// obtain the image's ratio
$ratio = ($or_h / $or_w);
// original image
$or_image = imagecreatefromjpeg($dir.$img);
// resize image?
if ($or_w > $max_w || $or_h > $max_h) {
// resize by height, then width (height dominant)
if ($max_h < $max_w) {
$rs_h = $max_h;
$rs_w = $rs_h / $ratio;
}
// resize by width, then height (width dominant)
else {
$rs_w = $max_w;
$rs_h = $ratio * $rs_w;
}
// copy old image to new image
$rs_image = imagecreatetruecolor($rs_w, $rs_h);
imagecopyresampled($rs_image, $or_image, 0, 0, 0, 0, $rs_w, $rs_h, $or_w, $or_h);
}
// image requires no resizing
else {
$rs_w = $or_w;
$rs_h = $or_h;
$rs_image = $or_image;
}
// generate resized image
imagejpeg($rs_image, $newdir.$img, 100);
$th_image = imagecreatetruecolor($th_w, $th_h);
// cut out a rectangle from the resized image and store in thumbnail
$new_w = (($rs_w / 2) - ($th_w / 2));
$new_h = (($rs_h / 2) - ($th_h / 2));
imagecopyresized($th_image, $rs_image, 0, 0, $new_w, $new_h, $rs_w, $rs_h, $rs_w, $rs_h);
// generate thumbnail
imagejpeg($th_image, $newdir.'thumb_'.$img, 100);
return true;
}
// Image type was not jpeg!
else {
return false;
}
}
$dir = './';
$img = '1.jpg';
$size = getimagesize($img);
$width = $size[0];
$height = $size[1];
resizejpeg($dir, '', $img, $width, $height, 150, 100);

I didn't understand correctly what you mean, but based on your description you are trying to get the image no 2 which means you are trying to crop an image. If that your mean, maybe this code will help
function crop($image_path, $output_path, $x, $y, $width, $height) {
// load image
$image = imagecreatefromjpeg($image_path);
// crop the image
$cropped_image = imagecrop($image, [
'x' => $x,
'y' => $y,
'width' => $width,
'height' => $height
]
);
// save it
imagejpeg($cropped_image, $output_path);
}
you can use it like this
// input image path
$image = "img.jpg";
// output image path
$output = "crop_img.jpg";
// crop it from (0,0)
crop($image, $output, 0, 0, 150, 100);
