// Create and save the result as a file named fileName (of which the type is gif).

// Parameters:
// fileName:
// Just as it looks like,it is the name of file you want to save as.
//
// args:
// A structure used to specify your own style image.Also,you can use a default
// one without passing it.
// Properties of Args:
// size:The length between two character.
// fontSize: The size of font,specified in pixel.
// spaceLen:The length from the end point of line to center of corresponding
// character.(spaceLen a little bit smaller than fontSize is recommended,e.g.
// fontSize=10,spaceLen=8.)
// basicLineColor:The color of line connected the consecutive characters.
// pairLineColor:The color of line between '1' and '1'.
// fontColor:The color of font.
