Examples

A simple example using templating syntax to generate a physical file:

<bx:set testImage = "https://ortus-public.s3.amazonaws.com/logos/ortus-medium.jpg"/>
<bx:document format="pdf" filename="/path/to/mydocument.pdf">
    <!--- Header for all sections --->
    <bx:documentitem type="header">
        <h1>This is my Header</h1>
    </bx:documentitem>
    <!--- Footer for all sections --->
    <bx:documentitem type="footer">
        <h1>This is My Footer</h1>
        <bx:output><p>Page #bxdocument.currentpagenumber# of #bxdocument.totalpages#</p></bx:output>
    </bx:documentitem>
    <!--- Document section, which will be bookmarked as "Section 1" --->
    <bx:documentsection name="Section 1">
        <h1>Section 1</h1>
    </bx:documentsection>
    <!--- Document section, which will be bookmarked as "Section 2" --->
    <bx:documentsection name="Section 2">
        <h1>Section 2</h1>
    </bx:documentsection>
    <!--- Document section, which contains an image --->
    <bx:documentsection src="#testImage#">
</bx:document>

Example, using script syntax to create a variable containing the binary contents of the PDF, which is then written to a file

bx:document format="pdf" variable="myPDF"{
    bx:documentsection name="Section 1"{
        writeOutput("<h1>Section 1</h1>");
        include "/path/to/section1.bxm";
    }
    bx:documentsection name="Section 2"{
        writeOutput("<h1>Section 2</h1>");
        include "/path/to/section2.bxm";
    }
}

fileWrite( "/path/to/mydocument.pdf", myPDF );
