@fumadocs/satteri@0.3.2

Introduce @fumari/image-size, replacing image-size in remarkImage

A fork of probe-image-size with no dependencies of its own.

import { probe, imageSize } from '@fumari/image-size';

await probe('./public/banner.png'); // { width: 1200, height: 630, type: 'png', mime: 'image/png' }
await probe('https://example.com/banner.png', { timeout: 5000 });

imageSize(bytes); // the same result, or `null`

remarkImage now uses it in both fumadocs-core and @fumadocs/satteri. Remote images are no longer downloaded in full just to be measured, and redirects are followed. Sizes are always in pixels, so an SVG sized in em or pt is converted instead of being skipped. Remote requests also time out after 30 seconds by default.

One behaviour difference worth knowing: the supported formats are avif/heic/heif, bmp, gif, ico, jpeg, png, psd, svg, tiff and webp. Sizes for jxl, tga, pnm, dds, icns, cur, ktx and jp2 can no longer be resolved and go through onError instead.

Sequential scanning stops after 512 KB, but that never loses an image: the one format that stores its dimensions past that point — TIFF with a trailing IFD — is resolved by following the header's pointer with a targeted read, using an HTTP Range request for remote files (and skipping through the body when the server ignores ranges).
