## About

## What it does
Image Filter applies a selected transformation to an image and returns the result either as a downloaded binary file or a signed URL. Send an image URL or upload image bytes, choose a filter, and get the processed image back.

Use this when you need to rotate, flip, blur, brighten, darken, or apply a gamma adjustment without building image-processing logic yourself. Supported filters include `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`, and `gamma_0.5`.

The URL-based endpoints accept a `url` in the request body, while the multipart endpoints accept an `image` file upload. In both cases, you can also pass `output` and `preserve_format` as query parameters. That makes it easy to keep the original format when you need to, or produce a named output for downstream storage and delivery.

Image Filter is a good fit for automated media pipelines, quick content adjustments, and server-side image normalization before upload, moderation, or sharing.
