+## Top-level options
+
+These global settings define how Hugo handles the fundamental aspects of image manipulation, such as cropping logic, background colors, and general output quality.
 
 anchor
-: (`string`) The focal point used when cropping or filling an image. Valid options include `TopLeft`, `Top`, `TopRight`, `Left`, `Center`, `Right`, `BottomLeft`, `Bottom`, `BottomRight`, or `Smart`. The `Smart` option utilizes the [`smartcrop.js`][] library to identify the most interesting area of the image. Default is `Smart`.

 bgColor
 : (string) The background color used when converting transparent images to formats that do not support transparency, such as PNG to JPEG. This color also fills the empty space created when rotating an image by a non-orthogonal angle if the space is not transparent and a background color is not specified in the  processing specification. The value must be an RGB [hexadecimal color][]. Default is `#ffffff`.

-method
-: (`int`) The effort level of the compression algorithm. Expressed as a whole number from `0` to `6`, inclusive, equivalent to the `-m` flag for the [`cwebp`][] CLI. Lower numbers prioritize processing speed, while higher numbers prioritize compression efficiency. Default is `4`.

+
+Use the `reflect.IsImageResourceProcessable` function to determine if a resource can be manipulated by Hugo's imaging pipeline such as resizing, cropping, or filtering.

+| image.webp | image/webp | true |
+
+Although AVIF, HEIC, and HEIF images are not processable, you can can determine their dimensions using the [`Width`] and [`Height`] methods.

+{{ with resources.Get "image.avif" }}
+  <img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}">
+{{ end }}

+
+## Example
+
+You can use this function to safely filter a collection of images before applying transformations, ensuring that the imaging pipeline only attempts to process supported formats.
+
+```go-html-template

+  {{ if reflect.IsImageResourceProcessable . }}
+    {{ with .Process "resize 600x webp" }}
