Rendering
=========
Aspect Ratio
------------
Inscriptions should be rendered with a square aspect ratio. Non-square aspect
ratio inscriptions should not be cropped, and should instead be centered and
resized to fit within their container.
Maximum Size
------------
The `ord` explorer, used by [ordinals.com](https://ordinals.com/), displays
inscription previews with a maximum size of 576 by 576 pixels, making it a
reasonable choice when choosing a maximum display size.
Image Rendering
---------------
The CSS `image-rendering` property controls how images are resampled when
upscaled and downscaled.
When downscaling image inscriptions, `image-rendering: auto`, should be used.
This is desirable even when downscaling pixel art.
When upscaling image inscriptions other than AVIF, `image-rendering: pixelated`
should be used. This is desirable when upscaling pixel art, since it preserves
the sharp edges of pixels. It is undesirable when upscaling non-pixel art, but
should still be used for visual compatibility with the `ord` explorer.
When upscaling AVIF and JPEG XL inscriptions, `image-rendering: auto` should be
used. This allows inscribers to opt-in to non-pixelated upscaling for non-pixel
art inscriptions. Until such time as JPEG XL is widely supported by browsers,
it is not a recommended image format.
