Re: [WebERP-developers] PDF generator in webERP.

[Rafael C. <raf...@gm...>]

Hi Andrew,

I enclose my new AddTextWrap. Inside ~/includes/class.pdf.php, replace
AddTextWrap lines (80-169) with lines 3-66 of the included file.

Comments:
* I'm testing with last version of Nicola Asuni's TCPDF.
* It is possible to replace line 56 ("$textwidth +=
$this->GetStringWidth($c);") with two lines. Those two lines makes the
function a little faster in some cases ($text width near the cell width),
but slower in other cases ($text width far from the cell width).

Best regards, Rafael.
