How does php crop images? Php image cutting code
- $ Src_path = '1.jpg ';
- // Create a source image instance
- $ Src = imagecreatefromstring (file_get_contents ($ src_path ));
- // Crop the coordinates of the points in the upper left corner of the area.
- $ X = 100;
- $ Y = 12;
- // Width and height of the cropping area
- $ Width = 200;
- $ Height = 200;
- // The image is saved to the width and height of the image, and the source-to-source ratio. Otherwise, the image will be deformed.
- $ Final_width = 100;
- $ Final_height = round ($ final_width * $ height/$ width );
- // Copy the cropping area to the new image and scale or pull the image up or down based on the width and height of the source and target.
- $ New_image = imagecreatetruecolor ($ final_width, $ final_height );
- Imagecopyresampled ($ new_image, $ src, 0, 0, $ x, $ y, $ final_width, $ final_height, $ width, $ height );
- // Output image
- Header ('content-Type: image/jpeg ');
- Imagejpeg ($ new_image );
- Imagedestroy ($ src );
- Imagedestroy ($ new_image );
Cropped image:
In fact, if the coordinates are (0, 0), the width and height of the cropping area are the same as those of the source image, then the thumbnail is generated.
The preceding section only lists the php image cropping examples, which are server-side functions. If needed, you can use the jquery plug-in imageAreaSelect to ensure compatibility. |
