draw()

void PreviewLayoutLinesTool::LineDetails::draw

(

bool

highlight

)

Draw a line in the preview for this pair of images.

If the line is a dud, no line is drawn.

• It is coloured grey and 1 pixel thick if there are no control points.
• The width of the line is max {1 px + NumberOfControlPoints / 5, 5}.
• The colour of a line with control points is dependant on the maximum error and selection:
  • Red if the error is greater than or equal to 20.
  • Red - Orange - Yellow if the error is between 5 and 20
  • Yellow - Green if the error is less than 5.
  • All lines are drawn white instead if it is the selected line.

    Parameters

    highlight

    Prelight for nearest line. Draws the line white when true, otherwise use a colour based on error.
