* @param {boolean} [options.unlimited=false] - Set this to `true` to remove safety features that help prevent memory exhaustion (JPEG, PNG, SVG, HEIF).
* @param {boolean} [options.sequentialRead=true] - Set this to `false` to use random access rather than sequential read. Some operations will do this automatically.
* @param {number} [options.density=72] - number representing the DPI for vector images in the range 1 to 100000.
* @param {number} [options.ignoreIcc=false] - should the embedded ICC profile, if any, be ignored.
* @param {number} [options.pages=1] - number of pages to extract for multi-page input (GIF, WebP, AVIF, TIFF, PDF), use -1 for all pages.
* @param {number} [options.page=0] - page number to start extracting from for multi-page input (GIF, WebP, AVIF, TIFF, PDF), zero based.
* @param {number} [options.subifd=-1] - subIFD (Sub Image File Directory) to extract for OME-TIFF, defaults to main image.
