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 tag
family: family of the font
style: N (normal) or combination of B, I, U
size: size
color: color (comma-separated RGB components)
indent: to be specified for the paragraph tag; indents the first line by the indicated value
bullet : character to use for bullets (typically chr(149)) ; must be used in conjunction with indent

It 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 line
txt: text to display - must have at least one tag at beginning and end to delimit a paragraph
border: 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.
