HTML to PDF

Discover how to create PDF formatted files from HTML using the HTML to PDF component for the Digibee iPaaS. Learn configuration parameters of this component here.

HTML to PDF allows the creation of files in PDF format from a HTML. The component uses Apache FreeMaker templates to generate the HTML through the pipeline JSON message.
Take a look at the configuration parameters of the component:
File Name: name of the PDF file to be generated in the output of the component execution.
Template (HTML): HTML template to be interpreted to generate the PDF file. This field supports the FreeMarker template.
Fail On Error: if the option is enabled, the execution of the pipeline with error will be interrupted; otherwise, the pipeline execution proceeds, but the result will show a false value for the “success” property.
Secured PDF: if the option is enabled, the insertion of a password in the PDF file is allowed to generate a protected document.
Password: password to protect the PDF file.
Custom permissions: if the option is enabled, custom permission options for the PDF file become available; otherwise, none of the following parameters will be available and the PDF file will be generated with all the permissions.
Read only: access permission that defines the PDF file as "read only". If the option is enabled, all the other access permissions will be disabled.
Assemble document: allows pages to be added, rotated or deleted from the file.
Modify: allows the file to be modified.
Modify annotations: allows text notes to be added or modified in the file.
Extract content: allows texts and images to be extracted from the file.
Extract for accessibility: allows texts and images to be extracted from the file for accessibility matters.

Messages flow
Input
The component accepts any input message, being able to use it through Double Braces.
Output
Successful
{  
    "success": true,  
    "fileName": "pdf_gerado.pdf" 
}
Unsuccessful
{  
    "success": false,"message": "Could not generate the pdf file", 
    "error": "java.net.IOException"
}
Example of request response with error:
{  
    "success": false,  "message": "Could not generate the pdf file",  
    "error": "java.net.IOException:"
}
success: “false” when the operation fails
message: message about the error
exception: information about the occurred error
Example:
Body
<p>We have these animals:<table border=1>  
<#list animals as animal>    
<tr><td>${animal.name}<td>${animal.price} Euros  
</#list></table>
Therefore, in the input message an object array is received and it has the properties “name” and “price”:
[
    { "name": "Dog", "price": 100},
    { "name": "Cat", "price": 100},
    { "name": "Bird", "price": 30}
]
The template will make the iteration in this received array and fill the HTML:
<p>We have these animals:<table border=1>
<tr><td>Dog<td>$100 Euros<tr><td>Cat<td>$100 Euros
<tr><td>Bird<td>$30 Euros 
</table>

    <rect x="50" y="20" rx="20" ry="20" width="150" height="150" style="fill:red;stroke:black;stroke-width:5;opacity:0.5" />
