fixedImageSharp

fixedImageSharp is a component within the Gatsby Image ecosystem, specifically designed for rendering images with a fixed, predetermined size. Gatsby Image is a powerful plugin for Gatsby that optimizes image loading and display by using GraphQL to query image data and then processing it into various formats and sizes. The fixedImageSharp component is one of the ways Gatsby Image can be utilized to integrate these optimized images into a website.

When using fixedImageSharp, developers specify the exact width and height that the image should occupy on the page. This is in contrast to fluidImageSharp, which creates images that scale responsively with their container. The output of fixedImageSharp includes a high-quality image file, a placeholder for faster initial loading, and potentially other optimized versions of the image, all managed by Gatsby's image processing pipeline. This ensures that even though the image is fixed in size, it is still delivered efficiently to the user, improving performance and user experience.

To implement fixedImageSharp, developers typically query for image data using GraphQL within their Gatsby pages or components. They then pass the required `width` and `height` arguments to the `fixed` argument in their GraphQL query. The component then receives the processed image data and renders it, maintaining the specified dimensions. This makes fixedImageSharp suitable for scenarios where precise image dimensions are critical, such as in grid layouts or specific design elements that require exact sizing.
