Commonly assumed
Passing null or a negative integer disables the input pixel limit, and exceeding it silently scales down the image.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- sharp rejects processing with 'Input image exceeds pixel limit' when pixel dimensions exceed limitInputPixels, and removing the limit requires 0 or false because null preserves the default 268402689 limit and negative integers throw a synchronous validation error.
- sharp processes images within the configured limitInputPixels threshold.
- limitInputPixels: false and limitInputPixels: 0 remove the limit and permit processing images exceeding previous bounds.
- limitInputPixels: null is ignored and leaves the default limit of 268402689 active.
- limitInputPixels: true resets the limit to the default 268402689.
- negative numbers or non-integer values throw a synchronous Error requiring a positive integer.
