When it is determined that the coordinates of the starting point and the coordinates of the ending point of the composite line T1 do not match, any one of the remaining constituent lines is selected and read as a line segment T2. (S103). Next, the coordinates of the start point or the end point of the composite line T1 and the coordinates of the start point or the end point of the read line segment T2 are compared to determine whether or not they match.

When it is determined that the coordinates of the starting point or the ending point of the composite line T1 do not match the coordinates of the starting point or the ending point of the line segment T2, one of the remaining constituent lines is further configured.

(10d−H) / 9 (equation (3)) is calculated, and the magnification A =
(H−t) / 10 (equation (1)) is calculated. Next, the coordinates are enlarged by the magnification A for each end point of the constituent line. For example, after the end point P1 (X, Y) is enlarged (reduced), the coordinates of the end point P1 are (X × (H−t) / 10, Y ×).
(H-t) / 10)).

As a result, the width of the character "A" is expanded to Wt and the height thereof is expanded to Ht. Next, a specific means for setting the line width of a character will be described. FIG. 6 and FIG. 7 show that the constituent lines are moved by t / 2 to the right with respect to the drawing direction of the loop of characters drawn by the graphic drawing apparatus for variable line width character information according to the embodiment, and the intersection of the constituent lines is changed.

Loops L1B and L2B after setting line widths corresponding to the constituent lines
The direction of the constituent line is compared with the direction of the constituent line of FIG. In the case of FIG. 8, since the drawing direction of the constituent line 111A of the loops L2 and L2B is opposite to the drawing direction of the constituent line 111B, the closed curve portion Q including the constituent line 111B of the loop L2B is removed.

Next, the specific means for this correction will be described. FIG. 9 is an explanatory diagram of a character correction method. The loop L2 before setting the line width includes the constituent lines 109A, 110A, 111A and 112A, and the end points P9, P10, P11 and P12 of the constituent lines. The loop L2B after the line width is set has the above-described constituent lines 109A, 110A, 111A and 112A.

P12 ′) projection amount in the X direction (D ′ = X coordinate of P12′−X coordinate of P11 ′) and the line segment of the component line before movement (P11)
P12) projection amount in the X direction (D = X coordinate of P12−P1
And the X coordinate of 1).

If D × D '> 0, the two line segments are not in opposite directions. If D × D ′ <0, then both line segments are in opposite directions.

If D × D '= 0, the projection amount in the Y direction is calculated, the projection amounts in the Y direction of both line segments are evaluated, and it is determined whether or not they are in the opposite directions.

Next, the coordinates of the intersection P0 'of the new constituent line are calculated, and P10'P0'P9' and P0'P11'P12 'are calculated.
And divide it into two loops. Next, the loop P0'P11'P12 'having the reverse line segment is deleted. As a result, the new constituent line becomes P10'P0'P9 '.
