Overview

The line tag is used to draw lines within a defined coordinate area. It supports various line styles, orientations, and visual properties.

Syntax

Line parameters can be specified as attributes (except nested elements) or as nested elements within the tag:

Element Syntax

Parameters

Coordinate parameters (required) that define the print area of ​​the line
<x1>: Starting X coordinate
<y1>: Starting Y coordinate
<x2>: Ending X coordinate
<y2>: Ending Y coordinate

The above parameters can alternatively be indicated in this way (one of the two methods is mandatory):
<x> Initial X coordinate (top/left corner)
<y> Initial Y coordinate (top/left corner)
<width> Width of the drawing area, calculated from the initial X coordinate
<height> Height of the drawing area, calculated from the initial Y coordinate

Parameters that define the appearance of the line (optional).

<orientation> Defines how the line is drawn relative to the specified coordinates. Possible values:
DiagonallyBackward (or DB alias) Diagonal line from top-left corner to bottom-right (default)
DiagonallyForward (or DF alias) Diagonal line from bottom-left corner to top-right
HorizontallyTop (or HT alias) Horizontal line at the top
HorizontallyBottom (or HB alias) Horizontal line at the bottom
VerticallyLeft (or VL alias) Vertical line on the left side
VerticallyRight (or VR alias) Vertical line on the right side

<linewidth> Specifies the thickness of the line (numeric value)

<linecolor> Defines the line color using hexadecimal color codes (e.g., "000000" for black, "00FF00" for green)

<linedash> Creates a dashed line pattern using two comma-separated values:
First value: Length of the dash segment
Second value: Length of the gap between dashes
Format: "dash_length,gap_length" (e.g., "2,4" creates 2-unit dashes with 4-unit gaps)

Creates a black diagonal line from coordinates (15,15) to (45,45) with 0.25 width and a dash pattern of 2-unit dashes with 4-unit gaps.

Example 1: Diagonal Dashed Line (Attribute Style)

Creates a horizontal black dashed line at the top of the defined area with equal 2-unit dashes and gaps.

Example 2: Horizontal Dashed Line

Creates a solid green vertical line on the left side with 0.35 width.

Example 3: Vertical Solid Line (Green)

Creates a solid black vertical line on the right side with 0.25 width.

Example 4: Vertical Solid Line (Black)
