* @param {boolean} [options.unlimited=false] - Set this to `true` to remove safety features that help prevent memory exhaustion (SVG, PNG).
* @param {boolean} [options.sequentialRead=false] - Set this to `true` to use sequential rather than random access where possible.
* This can reduce memory usage and might improve performance on some systems.
