# Examples

Example 1. Basic PECL/haru example

`<?php
$doc = new HaruDoc;
$doc->setPageMode(HaruDoc::PAGE_MODE_USE_THUMBS); /* show thumbnails */
$page = $doc->addPage(); /* add page to the document */
$page->setSize(HaruPage::SIZE_A4, HaruPage::LANDSCAPE); /* set the page to use A4 landscape format */
$courier = $doc->getFont("Courier-Bold"); /* we'll use the bundled font a few lines below */
$page->setRGBStroke(0, 0, 0); /* set colors */
$page->setRGBFill(0.7, 0.8, 0.9);
$page->rectangle(150, 150, 550, 250); /* draw a rectangle */
$page->fillStroke(); /* fill and stroke it */
$page->setDash(array(3, 3), 0); /* set dash style for lines at this page */
$page->setFontAndSize($courier, 60); /* set font and size */
$page->setRGBStroke(0.5, 0.5, 0.1); /* set line color */
$page->setRGBFill(1, 1, 1); /* set filling color */
$page->setTextRenderingMode(HaruPage::FILL_THEN_STROKE); /* fill and stroke text */
/* print the text */
$page->beginText();
$page->textOut(210, 270, "Hello World!");
$page->endText();
$doc->save("/tmp/test.pdf"); /* save the document into a file */
?>`

Open the result document in your favourite PDF viewer and you should see a light-blue rectangle and white "Hello World!" on it.

# Builtin Fonts And Encodings

## Builtin Fonts

These Base14 fonts are built-in into PDF and all viewers can display them. Using these fonts may decrease the size of the result file and make the processing faster, avoiding loading external fonts. However the fonts support only latin1 character set and you have to load external fonts if you need to use an other character set.

The Base14 fonts:

- Courier

- Courier-Bold

- Courier-Oblique

- Courier-BoldOblique

- Helvetica

- Helvetica-Bold

- Helvetica-Oblique

- Helvetica-BoldOblique

- Times-Roman

- Times-Bold

- Times-Italic

- Times-BoldItalic

- Symbol

- ZapfDingbats
