In the conventional painting processing method, the accuracy near the vertices of the contour depends on the line width of the line to be painted. Decrease. Conversely, when painting is performed with a painting line with a small line width, the accuracy is improved, but the number of painting lines to be generated increases. As a result, the data amount of the painting process becomes enormous, and the processing time of the output device becomes longer.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and the processing of the output device is performed while sufficiently maintaining the accuracy of the outline by applying a plurality of painting lines having different line widths. It is an object of the present invention to provide a computer-readable recording medium in which an application processing method, an application processing method, and an application processing program that can be sped up are recorded.

In the line width list 3 stored in the storage device 4, the line widths of a plurality of painted lines are registered.

The data processing device 2 includes a line width selection unit 6 for selecting a desired line width from the line width list 3 stored in the storage unit 4 and a line width selection unit along the contour of the painted area. The contour tracing means 7 to be painted with the painting line having the line width selected by the line 6, and the painted area other than the area painted by the contour tracing means 7 are replaced by the line width selected by the line width selecting means 6. Contour scanning means 8 for scanning in a predetermined direction with a painting line to paint.

The line width selecting means 6 acquires the line width from the line width list 3 and transmits it to the contour tracing means 7, the contour scanning means 8 and the output device 5.

The contour tracing means 7 obtains the line width of the painting line from the line width selecting means 6 and, along the line segment constituting the contour of the painting area obtained from the input device 1, cuts the half of the line width. A center line of the paint line is generated at the position of the distance. The center line is generated inside the contour indicating the outer periphery of the painted area, and outside the contour representing the non-painted area when there is a non-painted area in the painted area.

FIG. 2 is an explanatory diagram showing the shape of the painting line. As shown in FIG. 2, the painting line L is a line segment having a width whose both ends are circles having a line width as a diameter, and the center line M connects the centers of the circles at both ends. Draw a line. A closed continuous line consisting of the center line M obtained by the contour tracing means 7 is called a trace line. The contour tracing means 7 transmits the obtained trace line to the output device 5. further,
The trace line obtained for the thickest line segment registered in the line width list 3 by the line width selecting means 6 is the contour scanning means 8
Tell also.

The contour scanning means 8 scans the area surrounded by the trace lines obtained from the contour tracing means 7 in the minus direction with the width of the thickest line registered in the line width list 3 and the center of the painted line. A line is obtained and transmitted to the output device 5.

FIG. 3 is a flowchart showing the operation of the application processing method of the present invention. First, the contour representing the painted area provided from the input device 1 is supplied to the contour tracing means 7. The contour tracing means 7 is a line width selecting means 6
, The thinnest line width of the line width registered in the line width list 3 is obtained. At the same time, the line width selecting means 6 transmits the line width to the contour scanning means 8 and the output device 5 (step S1).

Next, the contour tracing means 7 generates a trace line with respect to the line width obtained in step S1, and transmits it to the output device 5 (step S2).

Next, if the line width registered in the line width list 3 has a line width larger than the line width used by the outline tracing unit 7 in step S2 (step S4), the outline tracing unit 7 sets the line width A thicker line width is acquired by the selection unit 6. The line width selecting means 6 selects the thickest line width within (1 + 2 ^-1/2 ) times the line width used by the contour tracing means 7 in step S2, and outputs the contour tracing means 7, the contour scanning means 8 and the output device. 5 (step S3).

In the present invention, the line width is increased at a magnification of (1 + 2 ^-1/2 ) times. However, the line width is increased at a magnification larger than (1 + 2 ^-1/2 ) times. Cannot be guaranteed,
This is because unpainted portions are left. Steps S2 and S3 are repeated until the thickest line width registered in the line width list 3 is reached.

Next, when the thickest line width is reached, contour scanning is performed (step S5). The contour scanning means 8
In step S2, a painted line having substantially the same line width as the trace line finally obtained by the contour tracing means 7 is used. The contour scanning means 8 scans the painted area in any direction parallel to the XY coordinates on the two-dimensional plane, and in the-direction with a width of a line segment thicker than the other direction. At this time, an intersection point between the scanning line and the trace line is determined to be within a region where a line serving as a start point and an end point is sequentially painted in ascending order of coordinates in the scanning direction, and a painted line segment is generated and transmitted to the output device 5. By setting the line width of the painting line to be the same as the width of the last trace line used by the outline tracing means 7, there is no possibility that the line runs out of the outline or remains unpainted.

Since the line width list 3 still has a large line width, the line width selection means 6 sets (1 + 2 ^-1/2 ) times 171 μm.
Select a maximum line width of 170 μm within
The maximum 2 within 290 μm, which is (1 + 2 ^−1/2 ) times 0 μm
Select 90 μm, then 290 μm (1+
A maximum line width of 480 μm is selected within 495 μm, which is 2 ^−1/2 ) times (step S3).
