This function generates a new image in the dimensions you specify, maintaining the aspect ratio by cropping when necessary.
Resize_image_crop($image, $width, $height) He is 100 x 100 pixels, but because no cropping occurred, the original aspect ratio was abandoned. Resize_image('force','penguin.jpg','penguin_force.jpg',100,100) įinally, we created this squished penguin using the resize_image_force function. Since the original is taller than it is wide, the new penguin is 100 pixels tall, but only 57 pixels wide. I have created three different functions that use PHP’s GD Image Functions to resize images on the fly. With the resize_image_max function, we specified that this penguin would have a max height or width of 100 pixels. Resize_image('crop','penguin.jpg','penguin_crop.jpg',100,100) Īs you can see, this poor penguin was cropped into a smaller image, 100 x 100 pixels, using the resize_image_crop function. In all three examples, we use the resize_image helper function to load up and save the actual image files. The penguin to the left is the image we’ll start with. Gravity positions for crops Automatic gravity for crops (gauto) Device Pixel Ratio (DPR) Here are some examples of different cropping or resizing techniques used on the same video: Auto-crop with focus on faces cfill,gauto:faces Pad with blurred background cpad,bblurred:400:15 Keep the right half ccrop,x0. Cloudinary's PHP library simplifies the generation of transformation URLs for easy embedding of assets in your PHP application. you can decide how many words they’re worth. For example, you can resize and crop, add overlay images, blur or pixelate faces, apply a large variety of special effects and filters, and apply settings to optimize your images and to deliver them responsively. They say a picture is worth a thousand words. We’ll start with the examples first and then explain how everything works. Additionally, I’ve constructed a function that loads and saves the images (in JPEG, GIF, PNG, or BMP format) and provides detailed error reporting in case something goes wrong. And the third forces the image into a specific size, even if that means that the aspect ratio is changed. The second allows you to set a maximum width or height and then shrinks the image to fit those specifications. The first crops images to fit to the new size so that the aspect ratio is maintained. I have created three different functions that use PHP’s GD Image Functions to resize images on the fly.
