The code snippets you've provided are examples of how to use Cloudinary's image transformation API via its SDK in JavaScript. Each example demonstrates a different way to manipulate images, such as resizing, cropping, and converting formats.
Here’s an explanation for each snippet:
-
Thumbnail with WebP format:
- This operation resizes the image to fit within 200x150 pixels while maintaining its aspect ratio.
- It then converts the image to the WebP format, which is highly efficient and supports transparency.
javascript1const operations = [ 2 { type: "resize", width: 200, height: 150, fit: "inside" }, 3 { type: "convert", format: "webp" } 4]; -
Constrain to max dimensions (never upscale):
- This operation ensures the image is resized so that it fits within a maximum width of 1920 pixels and height of 1080 pixels without upscaling.
javascript1const operations = [ 2 { type: "resize", width: 1920, height: 1080, fit:
