Hi,

hortabmethod=typewriter is unappropriate for indentation.

Hello,

maybe someone can help me with following problem with tables.

I have an invoice document. All items of this invoice I add to an table with
add_table_cell. After that, I print the complete table to the document. If there
an page-break (_boxful), I print on the bottom of the page (not in the table)
the subtotal. That's running fine. Now I must print the same value on the next
page as balance brought forward (but within the table). Can I add "dynamically"
a row (with add_table_cell) to the table, or can I say that the content of the
table need space after the header, but not on the first table instance (on
every page I print an header)?

One solution will be don't print the header in the table. But is there an
solution, that I can print the header "automatically" with fit_table?

Here an graphical example:

(HEADER): Pos Item name price
1 AAA 50
2 BBB 50

Subtotal: 100

(HEADER): Pos Item name price
Balance brought forward: 100
3 CCC 50

Have someone an idea?

just a quick idea, create a two row header but the second
line contains only a matchbox.
After fitting the table, you can retrieve the matchbox position
and place the " Balance brought forward: 100" similar as we
demonstrate the "subtotal" in the following example:
http://www.pdflib.com/pdflib-cookbook/tables/table-invoice/

Not perfect, because you will also have an "empty" row on the
first instance.

There is no way to insert rows afterwards.

This is not directly related to pdflib but someone might have an answer to it:

i need to change and write blocks .. not only in acrobat :-) so i went with your
proposed pdfmarks and join a pdfmark file with a pdf using ghostscript like
this:

   gs -q -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sOutputFile=fileout.pdf pdf_marks
pdf_with_blocks.pdf


the new file contains the blocks defined in the pdfmarks but has lost its
original pdflib blocks.

btw: i would really like to see block writing capabilities in pdflib because
right now i will need to go this way .. correct me if i am wrong:

- got pdf with blocks
- read them with pcos/pdflib
- user edit blocks
- convert to pdfmarks markup
- save back to a new pdf with gs .. and potentially loose stuff

after reading a bit in your bible. i probably found out why blocks are lost. You
are inserting them also as pdfmarks and those dont get joined.
Are there other pdflib options besides block potantially in pdfmarks?
Title/Author,.. so if i am editing such a template i would also need to take
care of those before writing again.

I can't enter a percent value for "horizscaling" after updating the block plugin
to 4.3. Is there a fix or workaround?

The german error message is: "Bitte geben Sie einen korrekten Wert für die
Eigenschaft 'horizscaling' ein".

Same problem with "charspacing" and "wordspacing".


Christian

Hi All,
I want to wrap the text coming dynamically inside a table cell, so first I am
creating a textflow then adding it to the cell. But it reduces the font size of
that cell as compare to other cell without textflow. I am using following code.
$fontNormal = $p->load_font($normalFont, "winansi", "");
$dimMargin=4;$dimStatCapheight=4;$dimStatMargin=3;$dimStatRrowHeight=10;
$dimCapheight=4; $dimLeading='120%'; $dimRrowHeight=32;
$trust['TrustIndexSurveyQuestion']['statement'] = "Some dynamic text";

$dimTfStatOpts = "font=" . $fontNormal . " alignment=left" .  "
fontsize={capheight=" . $dimStatCapheight . " } leading=" .$dimLeading;
$dimTf =$p->add_textflow(0,  $trust['TrustIndexSurveyQuestion']['statement'],
$dimTfStatOpts);
if($dimTf == 0){
	 die("Error: 3" . $p->get_errmsg());
}
$dimTbCellOpts = "textflow=" . $dimTf .  " fittextflow={firstlinedist=capheight
}" .  " colwidth=" .$dimStatColWidth. " rowheight=" . $dimStatRrowHeight .  "
margin=" . $dimStatMargin ;
$dimTb = $p->add_table_cell($dimTb, $col,$row, "", $dimTbCellOpts);


This is how I am adding textflow to the cell. Data is coming properly, but
fontsize is reduced as compared to other cell without textflow. please help me.
Thanks

Hi,

I wrote a C++ program which allow to create pdf dynamically with Unicode Text
(especially arabic text but not only)
My question concerns fit_textline method and more particularly the "wordspacing"
option.
It can happens that my text contains U+00A0 characters.(no-break space)
But in that case,  "wordspacing" option doesn't have the same behavior depending
on the font that I apply on the text.
Pdflib seems to convert U+00A0 character to U+0020 character with some fonts so
that fit_textline with "wordspacing" option shifts text after U+00A0 character
too ...
It is possible to avoid this function's behavior?

Many thanks in advance

Hi Rainer,

after updating to 4.4 the "percent value" problem is fixed. But a new problem
occurred.

I can't paste text from the clipboard to "defaullttext" (Acrobat 9 / MAC). In
fact pasting data from the clipboard doesn't work on any field.


Greetings
Christian

I've tried unsuccessfully many times to compile the PDFlib-Lite-7.0.5.zip files
with Visual C++ 2008 Express Edition on Win XP Pro with all updates installed.

VS C++ configuration was Active(Release) Active(Win32) Configuration Manager was
Release DLL Win32

Build Solution pdflib_dll reports missing files below
TCL missing tcl.h
Python missing python.h
missing EXTERN.h
Java missing jni.h
Perl missing pdflib_pl.sbr

Verified 5 missing files DO NOT exist in PDFlib-Lite-7.0.5.zip download.

Please provide some clues how to proceed.

Hello,

I have a question about a file that has sprung up on me only twice in
the last 4 years of using PDFLib.  First off, forgive my limited
knowledge of PDFs, I make heavy use of PDFLib but when I encounter a
problem like the following, I feel like a 10 year old in a calculus class.

I have an existing PDF file that has multiple separations (CMYK and
Pantone colors). When the PDF is opened in illustrator, a few particular
colors DO NOT render until the "Simulate Overprinting" option is turned
on in the "Output Preview" window. Once that is turned on, the colors
render and the PDF looks correct. I currently use PDFLib to process PDF
files and add annotations to them. When I process this file, I need to
be able to get PDFLib to render these spot colors, like I was checking
off that option in Acrobat (currently colors aren't rendering)

The code I use for processing the PDF looks like:

$page = $pdflib->open_pdi_page($outputPDF, $pageNum, '');
if (!$pdfPage) {
...
}

$width = $pdflib->get_pdi_value('width', $sourcePDF, $pdfPage, 0);
$height = $pdflib->get_pdi_value('height', $sourcePDF, $pdfPage, 0);
$pdflib->begin_page_ext($width, $height, '');
$pdflib->fit_pdi_page($pdfPage, 0, 0, 'adjustpage');

I've tried adding the following before the call to fit_pdi_page but it
hasn't made a difference:

$gState = $pdflib->create_gstate("overprintfill overprintmode=1");
$pdflib->set_gstate($gState);

Any thoughts would be much appreciated!

Thanks,
David

I am testing pdflib via the PDFlib TET Plugin on Acrobat Pro version 10.1.2 for
OS X.

The first file I am testing it on contains text that Acrobat and Preview both
permit me to select and copy, but the character mapping is nonstandard, so
pasted text is garbage without being remapped. For example, the string "dress
worn by Yolmo women" appears, after being copied by either Acrobat or Preview
and then pasted, as ":1*33#='15#(4#>'98'#='8*5".

My understanding is that such remapping is one of the problems that pdflib is
designed to solve.

However, when I select any text with Acrobat, the TET Copy menu item is disabled
gray. When I instead select the Copy Contents of current Page or Copy Contents
of all Pages menu item, I received an error dialog saying "No text found in
document".

Acrobat and Preview can find text in this document. Acrobat cat export the
document as HTML or PostScript (with the characters remapped into garbage, as
above). So I am surprised that PDFlib TET Plugin cannot find any text in the
document.

In fact, I can't get the plugin to find any text in any PDF document.

I have also installed TET and tried it, too. It does succeed in finding text in
this PDF and other PDF files, and converting PDF files to txt files. However,
the remapped file's conversion contains the same garbage characters as one gets
by copying with Acrobat or Preview and pasting.

Hello,

can someone tell me in which unit the value 'text-height' is returned?

- pixel?
- millimeters?
- point?

Thanks!

Jonathan,

might it be possible, that you open a support case for this topic
at support@... and provide us such a problematic PDF file.
(http://www.pdflib.com/en/support-policy/opening-a-support-case/)

Then we might analyses this in detail, what's happens in your case.

from the PDFlib API reference, chapter 5.4 table 5.16:
"Height of the bounding box of the whole text (taking firstlinedist and
lastlinedist into account) in current user coordinates"
In the PDFlib 8 Tutorial, the coordinates system is explained in detail:
(chapter 3.2.1 "Coordinate Systems"):
"PDFlib client programs may change the default user space by rotating,
scaling, translating, or skewing, resulting in new user coordinates."

=> textflow returns the "textheight" in your used coordinates. If no
scaling is involved, then the value is in points.

How would I create a section header on a page that is basically bold text that
is left justified in a shaded rectangle. That rectangle stretches the width of
page (minus margins) and has a slightly darker color for the border then it's
fill.

I've tried doing this with fit_textline() using various options unsuccessfully
so I'm wondering if I need to accomplish this by drawing the rectangle and then
using fit_textline() to draw the text on top of it like below:

p.save();
p.setlinewidth(.1);
p.setcolor("fill", "rgb", .9, .9, .9, 0);
p.setcolor("stroke", "rgb", .8, .8, .8, .8);
p.rect(lm, vPos-6, 612-lm*2, 13);
p.fill_stroke();
p.restore();

p.fit_textline("ACCOUNT TYPE", lm, vPos-6, "font=" + font + " position={left
center} fontsize=13  strokewidth=.1 boxsize={400 13} "+
					 " margin=4 ");

I should also note that basically the entire pdf we are trying to create is
basically a bunch of cells containing a label and then a blank area that will
either be filled out by person after printing or we will fill it in
electronically. Each cell has border and they can be adjacent to other cells on
all sides.  This is not a table since each row can contain a different number of
cells and they do not necessarily line up with those above and below, but they
all have borders.

Many Thanks

Hi,

I don't understand your problem completely, but I think that you want
to decorate a text dynamically. You can achieved this by means of
option "matchbox" (see PDFlib Tutorial, section 8.4.1).

The option "strokewidth=.1" in p.fit_textline() has only an effect
for underline, strikeout, overline and outline text.

Please contact our support
(http://www.pdflib.com/support-policy/opening-a-support-case/) and show
us your page layout about you
mean that it cannot be realized by PDFlib's table engine.

   PDFlib 8: Complex script shaping and bidirectional formatting
for Arabic, Hebrew, Thai, Hindi, and many other writing systems
_______PDFlib - a library for generating PDF on the fly________

Ahoi all

I am using the Ruby bindings to PDFlib.

I have a PDF file stored in a location that is not the usual file-system
(Inside a database) and want to pass this PDF data into PDFLib for
processing from ruby.

For example

require "./Pdflib"

# databse stuff

data =  @database_record.pdf_file.data
# data is a string, same as if it were done via ruby's File.read

p = Pdflib.new

p.open_pdi_???

Now at this point I would go to open_pdi_document but this will only
take the name of a file on the file-system. Is there a way to bring the
data into PDFLib without having to write a temporary file just so that
open_pdi_document can read it?

We want to avoid hitting the physical disk since it is a bottleneck in
what we want to be a fast system (Plus some other security related stuff
about having to delete temporary files).

I have looked through the documentation but cannot see anything obvious.

Regards,

Jeff

please check out the PDFlib Virtual Filesystem (PVF) to solve your
request. We demontrate this for images in starter_pvf.rb, but this
technique works exactly in the same way also for PDI.
