printform-pdf.php incompatable with tcpdf version 6.0.018

printform-pdf.php references function convertHTMLColorToDec.

The current version of tcpdf has moved convertHTMLColorToDec into the static class TCPDF_COLORS.

I was able to get the example functioning by changing the references of this->_pdf->convertHTMLColorToDec
to
TCPDF_COLORS::convertHTMLColorToDec

example:
$color = TCPDF_COLORS::convertHTMLColorToDec((string)$param);

Hello Chris, thanks for notification.
I've fixed source code, so PrintformPDF can be used with old and latest TCPDF versions.

The new function also requires a second parm for Spot Colors.

Also, they don't make the TCPDF object's spot colors public.

To fix this I added another class variable.

private $_spot_colors = array();

And passed it into the function:

if(class_exists('TCPDF_COLORS')) return TCPDF_COLORS::convertHTMLColorToDec($clr, $this->_spot_colors );

Idealy TCPDF would make the second parm in convertHTMLColorToDec optional.

Fixed. (I don't use PHP 5.3, so couldn't test pervious update with TCPDF 6.0.18)

I am using another PDF printing driver:
yiigo.com/guides/csharp/how-to-prin ...
And I haven't met such a problem.

You can add the following function to tcpdf.pdf classe and do no changes
