In our previous paper (1990), we discussed methods of expressing the composition knowledge of Chinese flower and bird paintings and proposed the dividing and composing method which could support computer painting based on the composition rules. In this paper, we attempt to apply this dividing and composing method to the various frames of paper (paintings using paper of different shapes) of Chinese flower and bird paintings. First, we analyzed the composition rules and described the expression method of composition knowledge in different frames of paper. Then, we defined the characteristic volume of painting elements, the frame centroid, the number of divisions and the division displacement to extract a dividing model. This procedure made possible the composition formation of various frames of paper.
