## About

## What it does
Image Filter lets you apply a fixed set of transformations to an image and return the result as a file or a signed URL. Send either a binary `image` upload or an image `url`, choose a `filter`, and optionally set `output` and `preserve_format`.

Use it for common image adjustments like `rotate_45`, `rotate_90`, `rotate_135`, `rotate_180`, `rotate_225`, `rotate_270`, `rotate_315`, `maximum`, `minimum`, `brightness_decrease`, `brightness_increase`, `gaussian_blur`, `flip_vertical`, `flip_horizontal`, or `gamma_0.5`. The service supports PNG, JPEG, JPG, BMP, TIFF, GIF, and WEBP when you fetch from a URL.

Choose the multipart endpoints when you already have the image file in hand. Use the URL-based endpoints when the image is hosted elsewhere and accessible to ApyHub services. Depending on the endpoint you call, the response is either binary image data or a `data` field containing a URI.

Image Filter is a good fit for product photo cleanup, simple creative effects, thumbnail preparation, and automated image pipelines where you need deterministic transforms without building them yourself.
