A processor of an information processing apparatus determines, if a drawing object making up page data of a print job is a transparent object having an alpha channel as color information, whether the transparent object overlaps another drawing object. If the transparent object does not overlap the other drawing object, the processor converts drawing data of the transparent object into drawing data of a drawing object not having an alpha channel as color information. If the transparent object overlaps the other drawing object, the processor does not convert the drawing data of the transparent object into the drawing data of the drawing object not having the alpha channel as color information. Based on the converted drawing data and on the non-converted drawing data, the processor creates PDL data to be output to an image forming apparatus.

An object of the present invention is to provide an information processing apparatus that reduces the amount of used memory necessary for alpha blending processing in a printer and enables high-speed printing processing. The present invention is an information processing apparatus including: an overlap determination unit configured to determine, in a case where a drawing object making up page data of a print job to be output to an image forming apparatus is a transparent object having an alpha channel as color information, whether the transparent object overlaps another drawing object; and a conversion unit configured to convert, in a case where the overlap determination unit determines that the transparent object does not overlap the other drawing object, drawing data of the transparent object into drawing data of a drawing object not having an alpha channel as color information.
