## Member Data Documentation

## ◆ e_LineCapButt

FSDK.GraphState.e_LineCapButt
| static

Enumeration for line cap style.

Values of this enumeration should be used alone. The line cap style specifies the shape to be used at the ends of open sub paths (and dashes, if any) when they are stroked.Butt cap. The stroke is squared off at the endpoint of a path. There is no projection beyond the end of a path.

## ◆ e_LineJoinBevel

FSDK.GraphState.e_LineJoinBevel
| static

Bevel line join type.

The two segments are finished with butt caps and the resulting notch beyond the end of the segments is filled with a triangle.

## ◆ e_LineJoinMiter

FSDK.GraphState.e_LineJoinMiter
| static

Enumeration for line join style.

Values of this enumeration should be used alone. The line join style specifies the shape to be used at the corners of paths that are stroked.Miter line join type.

The outer edges of the strokes for the two segments are extended until they meet at an angle.

## ◆ e_LineJoinRound

FSDK.GraphState.e_LineJoinRound
| static

Round line join type.

An arc of a circle with a diameter equal to the line width is drawn around the point where the two segments meet, connecting the outer edges of the strokes for the two segments.

## ◆ line_cap

FSDK.GraphState.line_cap

Line cap style.

The line cap style specifies the shape to be used at the ends of open sub-paths (and dashes, if any) when they are stroked. Please refer to values starting from FSDK.GraphState.e_LineCapButt and this should be one of these values.

## ◆ line_join

FSDK.GraphState.line_join

Line join style.

The line join style specifies the shape to be used at the corners of paths that are stroked. Please refer to values starting from FSDK.GraphState.e_LineJoinMiter and this should be one of these values.

## ◆ line_width

FSDK.GraphState.line_width

Line width.

It should be a non-negative number in PDF coordinate system. If 0 is set to this, it will be treated as 1 by default.

## ◆ miter_limit

FSDK.GraphState.miter_limit

The miter limit for line join.

When two line segments meet at a sharp angle and mitered joins have been specified as the line join style, it is possible for the miter to extend far beyond the thickness of the line stroking the path. The miter limit imposes a maximum on the ratio of the miter length to the line width. When the limit is exceeded, the join is converted from a miter to a bevel.
Please refer to <PDF Reference 1.7> P217 "Miter Limit" for more details.
