Draws a line composed of several segments in an Image control.
The first coordinate indicates the starting point of the first segment, then each coordinate indicates the end of the previous segment and the beginning of the next segment.
Example
IMG_Drawing.Pen(LightBlue, 2, 4)
arrCoordinatesXY2 is array of 0 int = [2, 2, 140, 2, 150, 70, 0, 100, 200,100]
IMG_Drawing.DrawPolyline(arrCoordinatesXY2)
Syntax

Building a line point by point Hide the details

<Image control>.DrawPolyline(<NbPoint> , <X1> , <Y1> , <X2> , <Y2> [, <Xn> [, <Yn> [, <Line color>]]])
<Image control>: Control name
Name of the Image control to use.
<NbPoint>: Integer
Number of line segments. This parameter defines the number of <X>, <Y> pairs to specify in the function.
<X1>: Integer
X coordinate of the first segment of the line. These coordinates are expressed in pixels.
<Y1>: Integer
Y coordinate of the first segment of the line. These coordinates are expressed in pixels.
<X2>: Integer
X coordinate of the second segment of the line. These coordinates are expressed in pixels.
<Y2>: Integer
Y coordinate of the second segment of the line. These coordinates are expressed in pixels.
<Xn>: Optional integer
X coordinate of the N segment of the line. These coordinates are expressed in pixels.
<Yn>: Optional integer
Y coordinate of the N segment of the line. These coordinates are expressed in pixels.
<Line color>: Integer or constant (optional)
Line color. This color can correspond to:If this parameter is not specified, the line color:
  • corresponds to the Color specified in the last call to the <Image>.Pen function,
  • is identical to the Color used for the Background if the <Image>.Pen function has not been used.

Building a line via an array of X and Y coordinates Hide the details

<Image control>.DrawPolyline(<Array of coordinates> [, <Line color>])
<Image control>: Control name
Name of the Image control to use.
<Array of coordinates>: Array of integers or array of points
WLanguage array of integers containing the coordinates of segments that make up the line. The even subscript represent the X coordinates while the odd subscripts represent the Y coordinates of points. These coordinates are expressed in pixels.
<Line color>: Integer or constant (optional)
Line color. This color can correspond to:If this parameter is not specified, the line color:
  • corresponds to the color specified in the last call to <Image>.Pen,
  • is identical to the Color used for the Background if the <Image>.Pen function has not been used.
Versions 26 and later

Construction of an row via an Variable type Polygon Hide the details

<Image control>.DrawPolyline(<Polygon> [, <Line color>])
<Image control>: Control name
Name of the Image control to use.
<Polygon>: Variable type Polygon
Name of the variable of type Polygon describing the different points of the Polygon.
<Line color>: Integer or constant (optional)
Line color. This color can correspond to:If this parameter is not specified, the line color:
  • corresponds to the color specified in the last call to <Image>.Pen,
  • is identical to the Color used for the Background if the <Image>.Pen function has not been used.

Remarks

Coordinates

Coordinates are given with respect to the top left corner of the image (coordinates: (0.0)).
