Abstract
Abstract A character pattern generator includes a ROM for storing font data and attribute information of each point of each stroke forming the font data, and a CPU for recognizing a portion to be transformed of a contour shape of the stored font data based on the attribute information of each point. The CPU further adds to the recognized portion to be transformed, a control point for performing transformation into a character pattern having a specified typeface code. The CPU then calculates the coordinates of the control point based on a factor at each point of each stroke of the font data. The CPU then transforms the contour shape by using the added control point and the font data. Finally, the CPU generates the character pattern having the specified typeface code based on the contour shape of the transformed font data.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
163 words
A character pattern generator in which a character pattern is transformed into an outline font data having a selectable typeface code, comprising: means for storing outline font data and attribute information of a plurality of points of each stroke forming the outline font data; means for selecting a character pattern and a typeface code; means for recognizing an end of each stroke forming the outline font data of the selected character pattern based on the attribute information of each point; means for calculating coordinates of a control point for performing transformation into the character pattern having the selected typeface code, based on the recognized end of each stroke; means for adding the calculated control point to the recognized end of each stroke; means for transforming a contour shape of the end of each stroke to include the added control point; and means for generating the outline font data of the character pattern having the selected typeface code based on the transformed contour shape.
Claim 2
Dependent Claim
163 words
A character pattern generator in which a character pattern is transformed into an outline font data having a selectable typeface code, comprising: means for storing outline font data and attribute information of a plurality of points of each stroke forming the outline font data; means for selecting a character pattern and a typeface code; means for recognizing an end of each stroke forming the outline font data of the selected character pattern based on the attribute information of each point; means for calculating coordinates of a control point for performing transformation into the character pattern having the selected typeface code, based on the recognized end of each stroke; means for adding the calculated control point to the recognized end of each stroke; means for transforming a contour shape of the end of each stroke to include the added control point; and means for generating the outline font data of the character pattern having the selected typeface code based on the transformed contour shape.
Claim 3
Dependent Claim
49 words
The character pattern generator as defined in claim 1, wherein the coordinate calculating means further comprises means for calculating the length of a stroke, and calculates an amount of movement from the contour line based on the length of the stroke to obtain the coordinates of the control point.
Claim 4
Dependent Claim
49 words
The character pattern generator as defined in claim 1, wherein the coordinate calculating means further comprises means for calculating the width of a stroke, and calculates an amount of movement from the contour line based on the width of the stroke to obtain the coordinates of the control point.
Claim 5
Dependent Claim
105 words
The character pattern generator as defined in claim 1, wherein the coordinate calculating means further comprises means for calculating the length of a stroke, means for calculating the width of the stroke, and means for calculating the ratio of the length of the stroke to the width of the stroke, and corrects the coordinates of the control point based on the ratio of the length of the stroke to the width of the stroke when calculating an amount of movement from the contour line based on the length of the stroke and the width of the stroke to obtain the coordinates of the control point.
Claim 6
Dependent Claim
32 words
