PHP Crop/Resize Image Function using GD Library
There are the Following The simple About PHP Crop/Resize Image Function using GD Library Full Information With Example and source code.
As I will cover this Post with live Working example to develop image upload and cropping with php and jquery, so the crop image in php source code for this example is following below.
index.php
<?php
class CustomImgManipulation
{
protected $resource;
public $destination;
public function Fetchresource($file)
{
$size = getimagesize($file);
$this->resource['width'] = $size[0];
$this->resource['height'] = $size[1];
$this->resource['type'] = $size['mime'];
return $this;
}
public function ConvertThumbs($source_imgs = '', $width = 60,$height = 60,$scaleImgName = false, $quality = 80)
{
// Set resource file settings
$this->Fetchresource($source_imgs);
// Determine kind to extract from
if($this->resource['type'] == 'image/gif')
$result_imgfile = imagecreatefromgif($source_imgs);
elseif($this->resource['type'] == 'image/png') {
$result_imgfile = imagecreatefrompng($source_imgs);
$quality = 7;
}
elseif($this->resource['type'] == 'image/jpeg')
$result_imgfile = imagecreatefromjpeg($source_imgs);
else
return false;
// Assign variables for calculations
$w = $this->resource['width'];
$h = $this->resource['height'];
// Calculate proportional height/width
if($w > $h) {
$new_height = $height;
$new_width = floor($w * ($new_height / $h));
$crop_x = ceil(($w - $h) / 2);
$crop_y = 0;
}
else {
$new_width = $width;
$new_height = floor( $h * ( $new_width / $w ));
$crop_x = 0;
$crop_y = ceil(($h - $w) / 2);
}
// New image
$result_imgfile_tmp = imagecreatetruecolor($width,$height);
// Copy/crop action
imagecopyresampled($result_imgfile_tmp, $result_imgfile, 0, 0, $crop_x, $crop_y, $new_width, $new_height, $w, $h);
// If false, send browser header for output to browser window
if($scaleImgName == false)
header('Content-Type: '.$this->resource['type']);
// Output proper image type
if($this->resource['type'] == 'image/gif')
imagegif($result_imgfile_tmp);
elseif($this->resource['type'] == 'image/png')
($scaleImgName !== false)? imagepng($result_imgfile_tmp, $scaleImgName, $quality) : imagepng($result_imgfile_tmp);
elseif($this->resource['type'] == 'image/jpeg')
($scaleImgName !== false)? imagejpeg($result_imgfile_tmp, $scaleImgName, $quality) : imagejpeg($result_imgfile_tmp);
// Destroy set images
if(isset($result_imgfile))
imagedestroy($result_imgfile);
// Destroy image
if(isset($result_imgfile_tmp))
imagedestroy($result_imgfile_tmp);
}
}
$ImageMaker = new CustomImgManipulation();
$source_imgs = 'profile.jpg';
$destination = 'result_ext_img.jpg';
$ImageMaker->ConvertThumbs($source_imgs,120,120,$destination);
?>
