            其他使用方法
            example: /latex?latexInput=a_{n%2B1}%3Da_n%2B2&outputFormat=PNG&outputScale=240%25&color=ffffff
            
            let latex = "a_{n+1}=a_n+k"
            `/latex?latexInput=${encodeURIComponent(latex)}&outputFormat=PNG&outputScale=200%25&color=white`

            目前大小只能透過 outputScale 來調整 , color 因為latex的關係，只能支援16色
