Description

This class provides two extended versions of the Cell method, one which prints horizontal text:

Cell(float w [, float h [, string txt [, mixed border [, int ln [, string align [, boolean fill [, mixed link]]]]]]])

and one for vertical:

VCell(float w [, float h [, string txt [, mixed border [, int ln [, string align [, boolean fill]]]]]])

These methods allow multiline text with the delimiter "\n".
If the cell contains a single line and its length exceeds the size of the cell, the text will be compressed to fit.

Changes in parameters:

border: indicates if borders must be drawn around the cell. The value can be either a number:
  • 0: no border
  • >0: frame of the corresponding width
or a string containing some or all of the following characters (in any order):
  • L: left
  • T: top
  • R: right
  • B: bottom
or for bold border:
  • L: left
  • t: top
  • R: right
  • B: bottom
Default value: 0.

For VCell():

align: allows to center or align the text. Possible values are:
  • U: top
  • C: center (default value)
  • D: bottom
