 - `-ls` or `-linespacing`: Space between text lines in pixels. Default is **8**.
 - `-hp` or `-hpad`: Horizontal padding amount in pixels. Default is **10**.
 - `-vp` or `-vpad`: Vertical padding amount in pixels. Default is **10**.
+- `-w` or `-width`: The width of the image when drawn, in pixels. By default this is **-1**. 
+  - A value of -1 disables fixed width scaling and instead uses automatic image scaling to resize (respecting aspect ratio) the image to the size of the longest line of text.
+- `-a` or `-align`: How the text should be aligned. Default is **Left**. Accepted values are **Left**, **Center** or **Right**. Not case-sensitive.
 - `-line`: The text to be drawn. This switch can be repeated multiple times to draw multiple lines of text. It can contain special tokens: `@os`, `@userName`, and `@machineName`. These tokens get substituted at runtime with system values for the operating system, current user, and machine name. 
   - If no lines are provided, it will render with the following by default:
   - "USERNAME: @userName"
