Discussion

The HTML_TO_PDF() function converts an HTML file (or an HTML string), with any links to contents in the same folder, into a PDF file.

dim htmlFile as c = "c:/test/myHtml.html"
dim htmlText as c = file.to_string("c:/test/myHtml2.html")
dim pdfFilename as c = "c:/test/myHtml.pdf"
dim obj as p

' Generated PDF from file
? HTML_TO_PDF(htmlFile,pdfFilename)
= .T.

' Generating a PDF from text without specifying a filename
? HTML_TO_PDF(htmlText,'',obj)
= .T.

? obj.pdfFilename
= "C:\Users\Janet\AppData\Local\Temp\AlphaAnywhere\p_29384\a5_temp_a5a14599_7b14_4fd4_a3fb_74e49378b006.pdf"

Specifying the Paper Size

You can specify page size (height and width) and margins (top, bottom, left, right) for the PDF directly in the HTML. The page size is defined as a JSON string in an HTML comment. For example:

<!--PAPER:
    {
    "width": "11in",
    "height": "8.5in",
    "margin": {
        "left": "0.5in",
        "right": "0.5in",
        "top": "1in",
        "bottom": "1in"
    }
}
-->

The PDF generated using the paper size definition above will have a page width of 11 inches and height of 8.5 inches (landscape) with left and right margins of 0.5 inches and top and bottom margins of 1 inch.
