Batch Url Parameters

Parameters that exist on URL based PDF services that can be used for batch processing PDFs.

batch

Array of URLs to convert to PDF and then combine into a single PDF file.

Required - Replaces URL parameter if defined.

array Default: []

Example - Extract Header Template

Html
<!DOCTYPE html>
<html>
<head></head>
<body>
<div class="page-header-bob" style="text-align: center">
<div id="header">
<span style="font-size: 20px; color: red">Header</span>
</div>
</div>
<h1>Page 1</h1>
<div style="height: 842px"></div>
<h1>Page 2</h1>
</body>
</html>
Parameters
{
"html": "PCFET0NUWVBFIGh0bWw+CjxodG1sPgogIDxoZWFkPiA8L2hlYWQ+CiAgPGJvZHk+CiAgICA8ZGl2IGNsYXNzPSJwYWdlLWhlYWRlci1ib2IiIHN0eWxlPSJ0ZXh0LWFsaWduOiBjZW50ZXIiPgogICAgICA8ZGl2IGlkPSJoZWFkZXIiPgogICAgICAgIDxzcGFuIHN0eWxlPSJmb250LXNpemU6IDIwcHg7IGNvbG9yOiByZWQiPkhlYWRlcjwvc3Bhbj4KCiAgICAgIDwvZGl2PgogICAgPC9kaXY+CiAgICA8aDE+UGFnZSAxPC9oMT4KICAgIDxkaXYgc3R5bGU9ImhlaWdodDogODQycHgiPjwvZGl2PgogICAgPGgxPlBhZ2UgMjwvaDE+CiAgPC9ib2R5Pgo8L2h0bWw+Cg=="
"margin": {
"top": "120px"
},
"headerTemplate": {
"method": "extract",
"selector": ".page-header-bob",
"style": {
"width": "100%",
"border": "1px solid red"
}
}
}

In the above code snippet called Parameters, the HTML is a base64 encoded string of the Html example above it. In this example, you can see how the div has a class named page-header-bob. This div is the header element extracted out of the body and moved into the header.

A caveat of using headers with PDFs is that the header exists inside the margins on PDF files. So, in this example, a margin-top of 120px is applied to make room for the header element to live. Otherwise, it will be covered up and not visible. By default, when the Chrome rendering engine renders HTML that exists in a header, it uses a font size that is extremely small and not legible, so a font size of 20px gets set on the span inside the header to allow the text to be readable.

footerTemplate

Template for the PDF header. See headerTemplate for reference. Can be used identically to the headerTemplate, only difference is the property name.

{
"footerTemplate": "<...same as headerTemplate>"
}

Units

For properties that accept string unit types, the following units are valid.

Note: If the property accepts a number it defaults to pixels.

  • px - pixel
  • in - inch
  • cm - centimeter
  • mm - millimeter
px - pixel (number)
{ "width": 100 }
px - pixel
{ "width": "100px" }
in - inch
{ "width": "100in" }
cm - centimeter
{ "width": "100cm" }
mm - millimeter
{ "width": "100mm" }
