 - **layout**: The layout for the image.
   - `CONSTRAINED`: (default) Resizes to fit its container, up to a maximum width, at which point it will remain fixed in size.
   - `FIXED`: A static image size, that does not resize according to the screen width
-  - `FLUID`: The image resizes to fit its container. Pass a "sizes" option if it isn't going to be the full width of the screen.

 - **outputPixelDensities**: A list of image pixel densities to generate, for high-resolution (retina) screens. It will never generate images larger than the source, and will always include a 1x image.

+  Default is `[ 0.25, 0.5, 1, 2 ]`, for fullWidth/constrained images, and `[ 1, 2 ]` for fixed.
 - **sizes**: The "[sizes](https://developer.mozilla.org/en-US/docs/Learn/HTML/Multimedia_and_embedding/Responsive_images)" attribute, passed to the `<img>` tag. This describes the display size of the image. This does not affect the generated images, but is used by the browser to decide which images to download. You can leave this blank for fixed images, or if the responsive image container will be the full width of the screen. In these cases we will generate an appropriate value. If, however, you are generating responsive images that are not the full width of the screen, you should provide a sizes property for best performance. You can alternatively pass this value to the component.
 - **formats**: an array of file formats to generate. The default is `[AUTO, WEBP]`, which means it will generate images in the same format as the source image, as well as in the next-generation [WebP](https://developers.google.com/speed/webp) format. We strongly recommend you do not change this option, as doing so will affect performance scores.
 - **quality**: The default quality. This is overridden by any format-specific options
