PROBLEM TO BE SOLVED: To provide an image forming device, its controlling method and a storage medium capable of evading a printing error and preventing the quality of an output image from being reduced by improving the using efficiency of a memory for storing a plotting object and suppressing the probability of memory error generation. SOLUTION: A 1st object specified by plural clip paths (e.g. three click paths ClipPat1, ClipPath2, ClipPath3) and having data volume depending on the number of vertex coordinates of each clip path is replaced with a 2nd plotting object specified by a single clip path indicating an area (e.g. an area constituting a quadrangle having four vertexes point1 to point4) on which respective clip areas are overlapped. Since data volume to be stored for the plotting object is reduced, free memory volume can be secured and the probability of memory error generation can be reduced. |
