Description

Feature Request

You can currently not set the image size for images or set both the width and height. You should be able to set either the width or height and have the other derived from the aspect ratio of the image

Implement Suggestion

Allow with_width or with_height and derive the other dimension

// Resize the image at compile time to make the assets smaller
pub const RESIZED_PNG_ASSET: Asset =
    asset!("/assets/image.png", AssetOptions::image().with_width(52));

or

// Resize the image at compile time to make the assets smaller
pub const RESIZED_PNG_ASSET: Asset =
    asset!("/assets/image.png", AssetOptions::image().with_height(52));

Contributor guide

Research direction
Examine the current `AssetOptions::image()` API and its dimensions handling. Implement logic to derive the missing dimension (width or height) from the image's aspect ratio when only one is provided.
