Method Detail

draw

public void draw(PdfCanvas canvas,
                 float x1,
                 float y1,
                 float x2,
                 float y2,
                 Border.Side defaultSide,
                 float borderWidthBefore,
                 float borderWidthAfter)

All borders are supposed to be drawn in such way, that inner content of the element is on the right from the drawing direction. Borders are drawn in this order: top, right, bottom, left.

Given points specify the line which lies on the border of the content area, therefore the border itself should be drawn to the left from the drawing direction.

borderWidthBefore and borderWidthAfter parameters are used to define the widths of the borders that are before and after the current border, e.g. for the bottom border, borderWidthBefore specifies width of the right border and borderWidthAfter - width of the left border. Those width are used to handle areas of border joins.

Specified by:

draw in class Border

Parameters:

canvas - PdfCanvas to be written to

x1 - x coordinate of the beginning point of the element side, that should be bordered

y1 - y coordinate of the beginning point of the element side, that should be bordered

x2 - x coordinate of the ending point of the element side, that should be bordered

y2 - y coordinate of the ending point of the element side, that should be bordered

defaultSide - the Border.Side, that we will fallback to, if it cannot be determined by border coordinates

borderWidthBefore - defines width of the border that is before the current one

borderWidthAfter - defines width of the border that is after the current one

drawCellBorder

public void drawCellBorder(PdfCanvas canvas,
                           float x1,
                           float y1,
                           float x2,
                           float y2,
                           Border.Side defaultSide)

Draws the border of a cell.

Specified by:

drawCellBorder in class Border

Parameters:

canvas - PdfCanvas to be written to

x1 - x coordinate of the beginning point of the element side, that should be bordered

y1 - y coordinate of the beginning point of the element side, that should be bordered

x2 - x coordinate of the ending point of the element side, that should be bordered

y2 - y coordinate of the ending point of the element side, that should be bordered

defaultSide - the Border.Side, that we will fallback to, if it cannot be determined by border coordinates

protected abstract void setInnerHalfColor(PdfCanvas canvas,
                                          Border.Side side)

Sets the fill color for the inner half of 3D Border

Parameters:

side - the side the color will be applied on

setOuterHalfColor

protected abstract void setOuterHalfColor(PdfCanvas canvas,
