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

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

Hi Vitaly,

Thank you for writing.

About
"$lines=explode("\r\n",htmlspecialchars_decode($myrow2['narrative']));":
This line returns an array of strings, each of which is a substring of
$myrow2['narrative'] formed by splitting it on boundaries formed by the
characters Carriage_Return ("\r") and Line_Feed ("\n"). It only works for
msWindows (Unix-like and Mac OS-10 use Line_Feed;  Mac OS up to version 9
uses Carriage_Return).

The problem in PrintCustTransPortrait.php (and other reports) is caused by
two bugs in AddTextWarp():

1. Line 108: "$s = trim($s).' ';" (extra blank character -> the extra white
line).
2. Lines from 106 to 164: (the logic of the code -> splitting in the last
white_space of a segment smaller that the cell width).

My purpose in asking if someone "has problem with this function (last line
line-feeded before the end) ?" is know who else experiences that problem.

I have a new AddTextWrap that fixes both bugs. It is faster and produces
PDF files with a slightly smaller size, but --obviously-- it not produce
the extra blank line in segments smaller than cell width. Many users like
this (no extra blank line) but there are some users who ask me to re-do
this extra blank line.

I would like other people tests this new AddTextWrap. Although this extra
blank line is a bug, I am not comfortable with the idea of a potential
change in actual reports.

Best regards, Rafael.
