``` The following classes allow you to inject printing values: * `date`: formatted print date * `title`: document title * `pageNumber`: current page number * `totalPage`: total pages in the document There are some limitations: * JavaScript is not executed * external resources are not loaded * the CSS properties are independant of the ones used in the `index.html` file * `footer.html` CSS properties override the ones from `header.html` * only fonts installed in the Docker image are loaded (see the [fonts section](#fonts)) * images only work using a `base64` encoded source (`
* `background-color` and `color` CSS properties require an additional `-webkit-print-color-adjust: exact` CSS property in order to work
### cURL
```bash
$ curl --request POST \
--url http://localhost:3000/convert/html \
--header 'Content-Type: multipart/form-data' \
--form files=@index.html \
--form files=@header.html \
--form files=@footer.html \
-o result.pdf
```
### Go
```golang
import)
setHeader($header);
$request->setFooter($footer);
$dest = 'result.pdf';
$client->store($request, $dest);
```
## Assets
You may also send additional files. For instance: images, fonts, stylesheets and so on.
The only requirement is to make sure that their paths
are on the same level as the `index.html` file.
In other words, this will work:
```html
```
But this won't:
```html
```
You may also use *remote* paths for Google fonts, images and so on.
> If you want to install fonts directly in the Gotenberg Docker image,
> see to the [fonts section](#fonts).

--header 'Content-Type: multipart/form-data' \
--form files=@index.html \
--form files=@style.css \
--form files=@img.png \
--form files=@font.woff \
-o result.pdf
```
### Go
```golang
import "github.com/thecodingmachine/gotenberg-go-client/v7"
c := &gotenberg.Client{Hostname: "http://localhost:3000"}
index, _ := gotenberg.NewDocumentFromPath("index.html", "/path/to/file")
style, _ := gotenberg.NewDocumentFromPath("style.css", "/path/to/file")
img, _ := gotenberg.NewDocumentFromPath("img.png", "/path/to/file")

req := gotenberg.NewHTMLRequest(index)
req.Assets(style, img, font)
dest := "result.pdf"
c.Store(req, dest)
```
### PHP
```php
use TheCodingMachine\Gotenberg\Client;
use TheCodingMachine\Gotenberg\DocumentFactory;
use TheCodingMachine\Gotenberg\HTMLRequest;
$client = new Client('http://localhost:3000', new \Http\Adapter\Guzzle6\Client());
$index = DocumentFactory::makeFromPath('index.html', '/path/to/file');
$assets = [
DocumentFactory::makeFromPath('style.css', '/path/to/file'),
DocumentFactory::makeFromPath('img.png', '/path/to/file'),
DocumentFactory::makeFromPath('font.woff', '/path/to/file'),
];
$request = new HTMLRequest($index);
$request->setAssets($assets);
$dest = 'result.pdf';
$client->store($request, $dest);
```
## Paper size, margins, orientation, scaling
You may also customize the resulting PDF format.
By default, it will be rendered with `A4` size, `1 inch` margins and `portrait` orientation and 100% (`1.0`) page scale.
> Paper size and margins have to be provided in `inches`. Same for margins.
### cURL
```bash
$ curl --request POST \
--url http://localhost:3000/convert/html \
--header 'Content-Type: multipart/form-data' \
--form files=@index.html \
--form paperWidth=8.27 \
--form paperHeight=11.69 \
--form marginTop=0 \
--form marginBottom=0 \
--form marginLeft=0 \
--form marginRight=0 \
--form landscape=true \
--form scale=0.75 \
-o result.pdf
```
### Go
```golang
import "github.com/thecodingmachine/gotenberg-go-client/v7"
c := &gotenberg.Client{Hostname: "http://localhost:3000"}
index, _ := gotenberg.NewDocumentFromPath("index.html", "/path/to/file")
req := gotenberg.NewHTMLRequest(index)
req.PaperSize(gotenberg.A4)
req.Margins(gotenberg.NoMargins)
req.Landscape(true)
req.Scale(0.75)
dest := "result.pdf"
c.Store(req, dest)
```
### PHP
```php
use TheCodingMachine\Gotenberg\Client;
use TheCodingMachine\Gotenberg\DocumentFactory;
use TheCodingMachine\Gotenberg\HTMLRequest;
use TheCodingMachine\Gotenberg\Request;
$client = new Client('http://localhost:3000', new \Http\Adapter\Guzzle6\Client());
$index = DocumentFactory::makeFromPath('index.html', '/path/to/file');
$request = new HTMLRequest($index);
$request->setPaperSize(Request::A4);
$request->setMargins(Request::NO_MARGINS);
$request->setLandscape(true);
$request->setScale(0.75);
$dest = 'result.pdf';
$client->store($request, $dest);
```
## Page ranges
You may specify the page ranges to convert.
The format is the same as the one from the print options
of Google Chrome, e.g. `1-5,8,11-13`.
### cURL
```bash
$ curl --request POST \
--url http://localhost:3000/convert/html \
--header 'Content-Type: multipart/form-data' \
--form files=@index.html \
--form pageRanges='1-3,5' \
-o result.pdf
```
### Go
```golang
import "github.com/thecodingmachine/gotenberg-go-client/v7"
c := &gotenberg.Client{Hostname: "http://localhost:3000"}
index, _ := gotenberg.NewDocumentFromPath("index.html", "/path/to/file")
req := gotenberg.NewHTMLRequest(index)
req.PageRanges("1-3,5")
dest := "result.pdf"
c.Store(req, dest)
```
### PHP
```php
use TheCodingMachine\Gotenberg\Client;
use TheCodingMachine\Gotenberg\DocumentFactory;
use TheCodingMachine\Gotenberg\HTMLRequest;
use TheCodingMachine\Gotenberg\Request;
$client = new Client('http://localhost:3000', new \Http\Adapter\Guzzle6\Client());
$index = DocumentFactory::makeFromPath('index.html', '/path/to/file');
$request = new HTMLRequest($index);
$request->setPageRanges('1-3,5');
$dest = 'result.pdf';
$client->store($request, $dest);
```
## Wait delay
In some cases, you may want to wait a certain amount of time to make sure the
page you're trying to generate is fully rendered. For instance, if your page relies
a lot on JavaScript for rendering.
> The wait delay is a duration in **seconds** (e.g `2.5` for 2.5 seconds).
### cURL
```bash
$ curl --request POST \
--url http://localhost:3000/convert/html \
--header 'Content-Type: multipart/form-data' \
--form files=@index.html \
--form waitDelay=5.5 \
-o result.pdf
```
### Go
```golang
import "github.com/thecodingmachine/gotenberg-go-client/v7"
c := &gotenberg.Client{Hostname: "http://localhost:3000"}
index, _ := gotenberg.NewDocumentFromPath("index.html", "/path/to/file")
req := gotenberg.NewHTMLRequest(index)
req.WaitDelay(5.5)
dest := "result.pdf"
c.Store(req, dest)
```
### PHP
```php
use TheCodingMachine\Gotenberg\Client;
use TheCodingMachine\Gotenberg\DocumentFactory;
use TheCodingMachine\Gotenberg\HTMLRequest;
use TheCodingMachine\Gotenberg\Request;
$client = new Client('http://localhost:3000', new \Http\Adapter\Guzzle6\Client());
$index = DocumentFactory::makeFromPath('index.html', '/path/to/file');
$request = new HTMLRequest($index);
$request->setWaitDelay(5.5);
$dest = 'result.pdf';
$client->store($request, $dest);
```
## Rpcc buffer size
The API might return a `400` HTTP code with the message `increase the Google Chrome rpcc buffer size`.
If so, you may increase this buffer size with a form field named `googleChromeRpccBufferSize`.
It takes an int as value (e.g. `1048576` for 1 MB).
The hard limit is 100 MB and is defined by Google Chrome itself.
> You may also define this value globally: see the [environment variables](#environment_variables.default_google_chrome_rpcc_buffer_size) section.
### cURL
```bash
$ curl --request POST \
--url http://localhost:3000/convert/html \
--header 'Content-Type: multipart/form-data' \
--form files=@index.html \
--form googleChromeRpccBufferSize=1048576 \
-o result.pdf
```

c := &gotenberg.Client{Hostname: "http://localhost:3000"}
index, _ := gotenberg.NewDocumentFromPath("index.html", "/path/to/file")
req := gotenberg.NewHTMLRequest(index)
req.GoogleChromeRpccBufferSize(1048576)
dest := "result.pdf"
c.Store(req, dest)
```
### PHP
```php
use TheCodingMachine\Gotenberg\Client;
use TheCodingMachine\Gotenberg\DocumentFactory;
use TheCodingMachine\Gotenberg\HTMLRequest;
use TheCodingMachine\Gotenberg\Request;
$client = new Client('http://localhost:3000', new \Http\Adapter\Guzzle6\Client());
$index = DocumentFactory::makeFromPath('index.html', '/path/to/file');
$request = new HTMLRequest($index);
$request->setGoogleChromeRpccBufferSize(1048576);
$dest = 'result.pdf';
$client->store($request, $dest);
