如何将Github风味的Markdown转换为PDF

```ruby
require 'redcarpet'
markdown = Redcarpet.new("Hello World!")
puts markdown.to_html
```

vim -c hardcopy -c quit /path/to/file.ps

:hardcopy >/path/to/file.ps

ps2pdf /path/to/file.ps

source-highlight -s java -f html -i Hello.java -o Hello1.html
source-highlight -s java -f html --input Hello.java --output Hello2.html --doc
source-highlight -s java -f html -i Hello.java -o Hello3.html --title "Happy Java with java2html :-)" --tab 3

# sudo apt install grip wkhtmltopdf

MD=${1:-README.md}
PDF=${2:-"$MD".pdf}
PORT=8971
DELAY=10

printf "Converting $MD to $PDF on port $PORT\n"
printf "Waiting $DELAY seconds for server to start...\n"

grip "$MD" localhost:$PORT &
sleep $DELAY
wkhtmltopdf http://localhost:$PORT "$PDF"
kill $(ps -eo pid,command | grep grip | grep -v grep | awk '{print }')

 <?php
require 'dompdf/autoload.inc.php';
use Dompdf\Dompdf;

$dompdf = new Dompdf();
$dompdf->getOptions()->setIsFontSubsettingEnabled(true);
$s_in = file_get_contents('index.html');
$dompdf->loadHtml($s_in);

$dompdf->render();
$s_out = $dompdf->output();
file_put_contents('index.pdf', $s_out);
 

 ## 1.1. Align images left, right, or centered, with NO WORD WRAP:

This:

```html
**Align left:**
<p align="left" width="100%">
    <img width="33%" src="https://i.stack.imgur.com/RJj4x.png"> 
</p>

**Align center:**
<p align="center" width="100%">
    <img width="33%" src="https://i.stack.imgur.com/RJj4x.png"> 
</p>

**Align right:**
<p align="right" width="100%">
    <img width="33%" src="https://i.stack.imgur.com/RJj4x.png"> 
</p>
```

Produces this:

**Align left:**
<p align="left" width="100%">
    <img width="33%" src="https://i.stack.imgur.com/RJj4x.png"> 
</p>

**Align center:**
<p align="center" width="100%">
    <img width="33%" src="https://i.stack.imgur.com/RJj4x.png"> 
</p>

**Align right:**
<p align="right" width="100%">
    <img width="33%" src="https://i.stack.imgur.com/RJj4x.png"> 
</p>

If you'd like to set the text itself to left, center, or right, you can include the text inside the `<p>` element as well, as regular HTML, like this:

```html
<p align="right" width="100%">
    This text is also aligned to the right.<br>
    <img width="33%" src="https://i.stack.imgur.com/RJj4x.png"> 
</p>
```
