A rendering apparatus comprising:

• an obtaining unit configured to obtain objects contained in a page;
• a separating unit configured to separate the objects into a first group and a second group, wherein a level of each object in the first group is closer to the background than a level of any object in the second group;
• and
• a rendering unit configured to generate a first bitmap by rendering the objects in the first group, and generate a second bitmap by rendering the object in the second group on the foreground of the first bitmap.

A rendering method comprising:

• obtaining objects contained in a page;
• separating the objects into a first group and a second group, wherein a level of each object in the first group is closer to the background than a level of any object in the second group;
• and
• generating a first bitmap by rendering the objects in the first group, and generating a second bitmap by rendering the object in the second group on the foreground of the first bitmap.

A non-transitory computer readable medium storing therein a program for causing a computer to perform a rendering method, said method comprising:

• obtaining objects contained in a page;
• separating the objects into a first group and a second group, wherein a level of each object in the first group is closer to the background than a level of any object in the second group;
• and
• generating a first bitmap by rendering the objects in the first group, and generating a second bitmap by rendering the object in the second group on the foreground of the first bitmap.
