-Does not preserve aspect ratio during image resizing.
+Allows for arbitrary image resizing when specifying both
+\f[C]--width\f[R] and \f[C]--height\f[R].
+By default, if both \f[C]--width\f[R] and \f[C]--height\f[R] are
+provided, the image\[cq]s aspect ratio is preserved (it does not get
+stretched in any direction), and the \f[C]--width\f[R] and
+\f[C]--height\f[R] specify the maximum amount of characters that the
+image be resized to.
+If you provide \f[C]--no-preserve-aspect-ratio\f[R], then
+\f[C]--width\f[R] and \f[C]--height\f[R] are exact dimensions, and the
+image might be squished accordingly.
