[image.resize]

image.resize is a slot in the image namespace, in Hyperlambda, the language of Magic Cloud. Resizes an image to the specified width and height; useful for generating thumbnails or fitting screen sizes.

• Value (image-file), required: Source image filename or stream to resize
• Returns: Resolves to the resized image stream unless [dest] is supplied, in which case the resized image is saved to disk and nothing is returned

Arguments
