Abstract

Abstract An image processing apparatus for drawing the inside of an image area which is expressed by vector data has reversal & painting means for sequentially reversing write dots (data) along the storage direction in correspondence to one outline which is specified by vector data, for writing the reversed write dots into an image memory, and for painting the inside of an image area like a closed figure in the image memory. Thus, the area in a closed figure can be painted at a high speed by a simple construction. The optimum reversal & painting method can be selective­ly switched in accordance with the attribute data of an image area to be painted, so that the optimum painting process can be executed at a high precision and at a high speed.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 49 words
An image processing apparatus having reversal & painting means for sequentially reversing dots (data) along a storage direction in correspondence to one outline which is specified by vector data, for writing said reversed dots into a memory, and for painting the inside of an image area in said memory.
Claim 2
Dependent Claim 49 words
An image processing apparatus having reversal & painting means for sequentially reversing dots (data) along a storage direction in correspondence to one outline which is specified by vector data, for writing said reversed dots into a memory, and for painting the inside of an image area in said memory.
Claim 3
Dependent Claim 80 words
An image processing apparatus comprising: reversal & painting means for sequentially reversing dots (data) on the basis of vector data, for writing said reversed dots into a memory, and for painting the inside of an image area; and storage control means for storing from both direction said reversed write dot data of each line which are output from said reversal & painting means so as to face a storage axis which by presumed by storage line data in said memory.
Claim 4
Dependent Claim 80 words
An image processing apparatus comprising: reversal & painting means for sequentially reversing dots (data) on the basis of vector data, for writing said reversed dots into a memory, and for painting the inside of an image area; and storage control means for storing from both direction said reversed write dot data of each line which are output from said reversal & painting means so as to face a storage axis which by presumed by storage line data in said memory.
Claim 5
Dependent Claim 57 words
An image processing apparatus comprising: a plurality of painting processing means for executing a painting process of the inside of an image area; discrimination means for discriminating an attribute of said image area; and selection means for selecting either one of said painting processing means on the basis of the attribute data discriminated by said discrimination means.
Claim 6
Dependent Claim 57 words
An image processing apparatus comprising: a plurality of painting processing means for executing a painting process of the inside of an image area; discrimination means for discriminating an attribute of said image area; and selection means for selecting either one of said painting processing means on the basis of the attribute data discriminated by said discrimination means.
