fixed potential crash bug (accessing invalid memory)

This change fixes a bug that occured when invoking the changed
function with a "graphic" parameter indicating undefined graphic,
which is defined as "-1" and caused an "array out of bounds" access.

To fix this bug, the function parameter is checked before used.
