Description
This extension lets you display several paragraphs inside a frame. The use of tags allows to change the font, the style (bold, italic, underline), the size, and the color of characters. You can also use indentation and bullets.To do this, 2 methods are available:
- The first one to define your tags:
SetStyle(string tag, string family, string style, int size, string color [, int indent [, string bullet]])tag: name of the tagfamily: family of the fontstyle: N (normal) or combination of B, I, Usize: sizecolor: color (comma-separated RGB components)indent: to be specified for the paragraph tag; indents the first line by the indicated valuebullet : character to use for bullets (typically chr(149)) ; must be used in conjunction with indentIt is possible to use empty strings or null values, except for the paragraph tag. The values are obtained by inheritance; for instance, with <p><u>, the non-specified values of <u> are replaced by those from <p>.
- The second one to output text:
WriteTag(float w, float h, string txt [, int border [, string align [, int fill [, mixed padding]]]])w: width of the line (0 to go from one margin to the other)h: height of a linetxt: text to display - must have at least one tag at beginning and end to delimit
a paragraphborder: 0 for none, 1 to have a border (default value: 0)align: justification of text: L, R, C or J (default value: J)fill: 0 for none, 1 for background filling (default value: 0)padding: either a numerical value or a string of the form "left, top, bottom, right"
with 2, 3 or 4 specified values (default value: 0)
Example
This example is the beginning of "Little Red Riding Hood" by Charles Perrault. Specific styles are applied to names of persons, of places, and to verbs.<?php
