I assume you mean can a programmer write an app in Livecode to extract 
test scores from a PDF and do something with them.


If the PDF has the test scores as text in the PDF (vs just a scanned 
image), then, yes, you can make a Livecode app that uses the PDF widget 
to open the PDF and retrieve the text from it and then parse that text 
for the test scores. If there is a routine pattern to the how the test 
scores appear, it will be easier to parse the text.

Printing to pdf

[jbv via use-livecode]

Hi list,

I have a stack with several cards 750 x 1000px.
I am trying to print these cards as pdf, but
according to this lesson
https://lessons.livecode.com/m/4071/l/29177-how-to-create-pdfs-using-livecode
the stack size should be 575 x 800 to fit a A4
document ratio.
Is it possible to "force" the printing to different
sizes, without clipping the content of the cards ?

I tried :
print card x into 0,0,750,1000
but the cards are still clipped.

The pdf I need to build is not for printing, only
for reading on screen.

Thank you in advance.
jbv

Re: PDF widget print quality

[Paul Dupuis via use-livecode]

I'm not sure it is possible. Livecode's printing tends to be card based 
and at card resolution, typically 72 dpi.


I recall seeing some efforts on the lists and forums to make an object 4 
times bigger (75 dpi x 4 = 300 dpi) so that when it is printed to a 
300dpi printer is is a higher resolution but normal size but I don't 
recall how successful any of those efforts were.


There is probably an ancient enhancement  request in the Livecode 
Quality Center to support higher-resolution printing.

Re: PDF Widget and JavaScript

[Bob Sneidar via use-livecode]

Thanks Ralph I figured as much. It’s actually not difficult to recreate from 
scratch if the structure, header and footer is known. The trouble is the 
fields. If I had a list of form controls for a given form, I could create one 
from scratch easily enough. 

The fillable forms have to be saved with an open file action to autofill, and 
if someone can do that, I suppose they already have the ability to export the 
fdf file using the javascript console in Acrobat Pro.

Hi all. 

This is a long shot, but is there any kind of PDF gadget in Livecode that can 
run javascript? I am specifically wanting to generate an FDF file from fillable 
forms. The javascript is fairly straightforward: 

This.ExportAsFDF(true, false, null)

This will work in a javascript enabled PDF application and will use the 
currently open PDF fillable document, generating an FDF file named after the 
PDF name (without the dot3 extension) appended by “_data.fdf” 

It would be quite the luxury to be able to do this in Livecode, otherwise I 
have to pay for a licensed Pro version (I think they are all subscription based 
now) and the ONLY thing I need from the Pro version is this function.

PDF Widget and Javascript

Hi all. 

This is a long shot, but is there any kind of PDF gadget in Livecode that can 
run javascript? I am specifically wanting to generate an FDF file from fillable 
forms. The javascript is fairly straightforward: 

This.ExportAsFDF(true, false, null)

This will work in a javascript enabled PDF application and will use the 
currently open PDF fillable document, generating an FDF file named after the 
PDF name (without the dot3 extension) appended by “_data.fdf” 

It would be quite the luxury to be able to do this in Livecode, otherwise I

Re: PDF Widget No Filled Forms

[Bob Sneidar via use-livecode]

No big rush. I can open the form in a web browser if necessary. My idea was to 
have a Native Document Viewer like the document management app we currently 
use, but I am not using my app for that yet. I just generate filled forms for 
service at the moment. I will create a bug report with a sample stack and form. 
I should note that this form is the kind where it can be filled using Adobe 
Reader. For some reason, Adobe has 2 kinds of forms.

Re: PDF Widget No Filled Forms

[matthias rebbe via use-livecode]

Bob,

as a workaround you could create a temporary pdf file that is then displayed in 
the pdf widget.
You'll need the free tool PDFTK server with its fill-form option for this.  
PDFTK server runs on macOS, Windows and some Linux versions. 
PDFTK server is free  https://www.pdflabs.com

If you need it for iOS or Android you could use a web server to which you post 
the .fdf or xfdf data and the web server then runs pdftk server, creates the 
pdf and returns it back to the device.

Not as easy then just opening the .(x)fdf file, but at least a solution. ;)

Regards,
Matthias

Hi Bob

Hmm… OK, it could be a bit of a project to get your forms rendering then. If 
it’s something you need soon and you have a budget then contact 
supp...@livecode.com <mailto:supp...@livecode.com>. Otherwise you can create a 
bug report and attach the PDF.

FYI there is no support for form interactivity at the moment so the select text 
is on the PDF text rather than the form fields.

be aware that you will lose one the most valuable things about a PDF
document: the embedded text layer.


Oh, no, there’s something more valuable, which you also lose:  anything
over 72 dpi!

I played with a pdf library for python for a bit, as well as raw pdf,
without much luck.

Just noticed that my steps are missing something.
So here's version 2 of it.

1. download
https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.pdflabs.com%2Ftools%2Fpdftk-the-pdf-toolkit%2Fpdftk_server-2.02-mac_osx-10.11-setup.pkg&data=05%7C01%7Croger.e.eller%40sealedair.com%7Ce1d5200433404eec54d008dba59780d1%7C2691a2514c384643af0b0c0982f197bd%7C0%7C0%7C638285842350859203%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=tEXnKnbF7xT3GjOMoYKIiM%2Fv3JwkS7pzKRM3op80KMI%3D&reserved=0<https://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/pdftk_server-2.02-mac_osx-10.11-setup.pkg>

2. to extract the pkg run the following in Terminal
pkgutil --expand   

If the source path to the pkg contains spaces then put quotes around the path.

3. Now open the destination path to which you've extracted the .pkg. There 
should be another pkg pdftk.pkg

4. right click the file pdftk.pkg  and select "show package content"

5. Now you should see a file payload. Right click that file and select "open 
with" and select the archive utility to decompress the file payload.

6. After extraction you'll find a new folder "Payload 2"

7. open that folder. In that folder you will find the Lib and Bin folder. Copy 
those folder to another location.

Now in LC you can use shell shell function to call the pdftk

Example
set the folder to "path to the bin folder"

put shell("./pdftk  file1.pdf file2.pdf file3.pdf cat output mynewfile.pdf")


would create combine the three file..pdf file into a new one called 
mynewfile.pdf

To use pdftk server in your standalone  you just have to include both folders 
in your standalone.


On Windows you first have to run the setup of pdftk server. During the 
installation you can select the folder where pdftk server shall be installed. 
You then can copy the bin folder from that installation folder
and use it with your standalone on any other computer without the need to run 
the setup on that computer.

Re: Merging PDF pages

[matthias rebbe via use-livecode]

On which OS are you planning to do this?

On Windows and macOS you could make use of PDFTK server from PDFLabs.com 
<http://pdflabs.com/>

On macOS  PDFTK Server normally  has to be installed to use it. But you could 
follow these steps here to get it working w/o installation.

1. Do not use the d/l link for pdftk Server from the pdfLabs website. That 
version will not work on macOS11 and up. Instead download this version of PDFTK 
Server. Sid Steward created a new version but did not update the d/l link
https://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/pdftk_server-2.02-mac_osx-10.11-setup.pkg

2. to extract the pkg run the following in Terminal
pkgutil --expand   

If the source path to the pkg contains spaces then put quotes around the path.

After extraction you'll find the 2 folders lib and bin and some others .The 2 
mentioned ones are needed. 

Now in LC you can use shell shell function to call the pdftk

Example
set the folder to "path to the bin folder"

put shell("./pdftk  file1.pdf file2.pdf file3.pdf cat output mynewfile.pdf")


would create combine the three file..pdf file into a new one called 
mynewfile.pdf


I wrote this in a hurry, so i might have some error in my explanation. Just 
ask, if you have problems.

Matthias

Re: Merging PDF pages

[panagiotis m via use-livecode]

Hello all,

There is a built-in utility on MacOS for merging PDFs. You can call it from
"shell", as Paul suggested.

This seems to work - tested on MacOS Mojave. It merges "test1.pdf" and
"test2.pdf" into "merged.pdf" on Desktop.
Just check that the path of tApp actually exists in modern MacOS as well.

on mouseUp pButtonNumber
   local tShell, tApp
   put quote & "/System/Library/Automator/Combine PDF
Pages.action/Contents/Resources/join.py" & quote \
 into tApp
   put tApp && "-o ~/Desktop/merged.pdf ~/Desktop/test1.pdf
~/Desktop/test2.pdf" \
 into tShell
   get shell(tShell)
end mouseUp

Cheers,
Panos

Re: Merging PDF pages

[Paul Dupuis via use-livecode]

The short answer is NO. There is nothing built into Livecode to take a 
set fo existing PDF files and append them to create a readable PDF that 
is them all stitched together. Neither the XPDF external nor the PDF 
widget will do this.


You best option is to use some 3rd party command line utility that will 
merge PDF files that works on the platform or platforms your want to do 
this on and use the Livecode shell() function to call that command line 
utility.


If this is going to be a distributed standalone, you can actually read 
the utility as a binary file and compress it as a staved property in 
your application, that can uncompress and install it on any target computer.


We do this with the popular free open-source video tool ffmpeg for macOS 
and WIndows. Our app install it if needed on the target computer from a 
compressed copy bundled into our app and we use SHELL() to call it to do 
several video operations that can't be done in Livecode.

Merging PDF pages

[Eller, Roger via use-livecode]

It's been a while since I've posted a question here.  Is it possible to use 
livecode script to merge multiple 1-page PDFs into a multipage PDF without 
using Acrobat or other 3rd party software?

Thanks.

Re: PDF widget and XPDFviewer

[Paul Dupuis via use-livecode]

I think the answer is complex. They are not the same thing, but 
eventually, the widget will replace the external. The current issue is 
that the widget is lacking some features the external has, so, if, (like 
us) you PDF work is based on the external, migrating to the widget is 
not possible (depending on features used) until the widget has the same 
features (or equivalent). If the widget will do all the PDF things you 
need to do, use it. If it does not, you will probably find those 
features with the external and need to use that. If what you want to do 
can be done in either, then use the widget.

PDF widget and "pinch zoom"

[Klaus major-k via use-livecode]

Hi all,

I just found out that the PDF widget supports "pinch zoom"
(correct term?) on Android. KIND OF!
It is VERY VERY jerky, but somehow works, yet unpredictable,
takes some seconds to finish.

Is this an undocumented feature?
If yes, any chance that this can/will be optimized so it really 
works as exspected, read "fluently"?

Thanks for any hint!


Best

Klaus

Re: Browser widget doesn't display PDF

Hello Panos,

thanks for reminding me of bug 22534.

filed. ;)

Thanks, i was not aware of that report. Btw. you are commenting in that report, 
that you could replicate the problem with a 316 page PDF, but not with a 5 page 
pdf.
In my case the PDF has only 1 page.

I knew that one already, because its a bug report based on a support request i 
filed. ;) 
To be honest, i almost forget about it. 
Rereading my comments i remembered that one hast remove the plugins and logoff 
and login again to get it working with the widget.

Btw. this might be a workaround for me if i need also the Acrobat plugins, but 
according to the dictionary the PDF widget is only available with a Pro license.
So this is not a workaround for everyone.


Anyway, thanks again.

Matthias

Browser widget doesn't display PDF

[matthias rebbe via use-livecode]

Hello,

i am currently having problems that a browser widget doesn't display a pdf, 
regardless if remote or local.

I just see a white blank page. Sometime an error message comes up telling me 
that "PDFViewer could not find a compatible version of Adobe Acrobat or Adobe 
Reader for displaying this PDF file."
Something like that. I get a German error message.

The interesting part is, that Safari does not have a problem with displaying 
the PDF and the folders ~/library/internet-plugins and 
/library/Internet-plugins both contain the Acrobat plugins.

Tried here with LC 9.6.9RC2 and 10DP4 on Ventura 13.0.1.

Does anyone has an idea what might be wrong?

Regards,
Matthias

Re: Printing (Preview in LC/screen vs Printer/PDF)

[Paul Dupuis via use-livecode]

A correction. The images are reduced to 1/4 size ONLY when printing to 
PDF on Windows (printing to paper results in the image at expected size)


This could be specific to Windows and the PDF "printer" (Foxit) being 
used. More testing is required. Premature posting ;-)

Re: PDF Printing

[Dan Friedman via use-livecode]

Mark,

Genius!  I can't thank you enough...  That worked!  Make sure that the field 
that holds the text has a valid font name and isn't inheriting a system-level 
font.  That REALLY ought to be documented in the PDF routines in LC.

As long as I have your ear...   Whenever I call this, I get a blank page in the 
beginning of my PDF.  I have checked that I'm not printing a blank page and 
have debugged this to death!   Any thoughts on a blank page being included in a 
PDF?

Someone had a similar problem in the past (Paul or Klaus maybe?) - it 
turned out that it was because no explicit font was set on the stack (or 
controls) - meaning that it was using the macOS 'theme' font.

This isn't actually a 'discoverable' font in the various font related 
APIs - and appears to be (somewhat!) hard-coded in the various low-level 
Apple graphics rendering APIs.

The PDF printer does use the correct fonts and metrics - and CoreText 
(on macOS) to do font layout - but the actual PDF generation is done 
using a cross-platform library (so the output is the same on all 
platforms) which relies on getting the 'real' font data for the given 
font (which it does not in this case) and not macOS (CoreGraphics-based) 
printing. The latter appears to be able to deal with the 'magic' fonts 
(unsurprising as its all Apple stuff), but our pdf printer cannot.

If you set the stack to an explicit font then the problem should go 
away.

Alternatively, if this is a mac-only product, you can use macOS's PDF 
printing capability by setting the printerOutput property to 
"file:" - on macOS the latter will generate a PDF (i.e. its 
the same as choosing 'Save As PDF' from the printer dialog).

Hope this helps!

Mark.

printing with dialog" it all looks perfect (even if I choose to save it to
PDF in the print dialog).   But, if I use the "open printing to pdf" method,
it get wrong fonts and inconsistent tab spacings.   Here is the EXACT code I
am using:

on mouseUp currSName
  put (the hilite of btn "printAsPDF" of stack "ReportOptions") into
printAsPDF

  if printAsPDF then
ask file "Save As PDF:" with (currSName & ".pdf")
put it into pdfPath
open printing to pdf pdfPath
  else
open printing with dialog
  end if

  if the result is "Cancel" then
exit mouseUp
  end if

  print card 1 of stack "GB_PReport"
  close printing

Re: PDF Printing

[Marty Knapp via use-livecode]

It could be a corrupted font cache - I’ve found that can cause weird behavior 
as you’re describing. If you’re on a Mac, do a “safe reboot” (start up with the 
shift key pressed) and after it boots up, do a normal reboot. That will delete 
the current font caches and then rebuild them from scratch. It’s little harder 
to fix on Windows - if that is the case you might Google that.

Worth a try anyway.

That is interesting. I tried here with content-length on on-rev and it works 
here with Version 15.6 (17613.3.9.1.5) of Safari.

At least you've found a solution...

Re: [semi-OT] PDF on the fly

I am using Safari 15.6 (15613.3.9.1.7, 15613)

But I finally found the origin of the problem :
  put header "Content-Length: " & number of chars of myPDF

After removing that line from the header, files download and
display fine in Safari, as in other browsers.
So far I have no rational explanation though.

Re: [semi-OT] PDF on the fly

I just checked here with a script i am using for years to provide the download 
of a csv file and it still works with Version 15.6 (17613.3.9.1.5).
Is that the newest version?

This is my script:

put header "Content-Type: application/text"
put header "Content-Length:" & the number of chars of tFileContent
put new header "Content-Disposition: attachment; FileName=" & tFileName
put URL("file:" & tFileContent)

The only difference i see is, that i haveput new header instead of put 
header

RE: [semi-OT] PDF on the fly

[Ralph DiMola via use-livecode]

How fortuitous...

I just ran into this while doing JavaScript xhttp network requests to LC
Server on Safari only. I just updated from LC Server 9.5.1. to 9.6.6. I saw
it in Safari in iOS. Chrome in iOS worked OK. I went back to 9.5.1 and
everything started working again in Safari. Do we possibly have the same
problem?

This might not be OT at all.

Hi list,

I have a web site on which end users can select several options, and then
click a button "show PDF", and a pdf containing various contents from a
remote DB with a sophisticated layout is built server side in a second and
automatically downloaded.

The link of the button is something like :
   https://domain.com/showPDF.lc?a=parameters
and the script sets the header of the pdf file as follows :
   put header "Content-Type: application/pdf"
   put header "Content-Length: " & number of chars of myPDF
   put header "Content-Disposition: attachment; filename=" "e&
myFileName "e

This has been working fine for years, and still works on Chrome and FF, but
apparently the latest versions of Safari don't accept it:
the file is built and the download starts but quickly stalls and that's it.
And no error message van be found in the console.

As an alternative solution, I've been thinking of building the pdf server
side and writing it in a temporary folder, and then on the web page
displaying a prompt with a button containing the actual url of the file. But
that's not very elegant IMHO.

What other options do I have ?
Thank you in advance.

OK, my fault, obviously I don't know exactly what the external is and can do.

I can't see how Livecode can replace the XPDF external with the PDF 
Widget UNTIL the PDF Widget provided all the functions the External does 
(and it does not). Well, of course they could drop the external even if 
it does a bunch of thinsg people depend on that the Widget does not, but

[Matthias Rebbe via use-livecode]

Ah thanks, Paul.
I copied already the xpdf from an older LC version to LC 10DP3.

But good to know that it will be back. XPDF allows me to get the imagedata of 
the currently rendered page and 'export' that as image.

I thought this has been replaced with the PDF widget, which is only available

It got removed from LC 9.6.6 and 9.6.7 and 10.0.0 dp 1 to 3. They 
(Livecode Support) said it would be back in LC 10.0.0 dp 4 and 
presumable and further releases in the 9.6.x series.


You can copy it from the 9.6.5 of earlier to the ccorresponding folder 
for LC 9.6.7. For example, on Windows it is C:\Program 
Files\RunRev\LiveCode 9.6.5\Ext\XPDF-1.0.45


Copy the XPDF-1.0.45 folder to the \Ext\ directory for LC 9.6.7

Re: Print to pdf fails on Windows with multiple pages

[matthias rebbe via use-livecode]

I can replicate this here also with 10DP2. 
And have attached a sample stack so others could also test.

But i could not attach the pdf. I am always getting this error here:

"It looks like you didn't come from the right page (you have no valid token for 
the create_attachment action while processing the 'attachment.cgi' script). The 
reason could be one of:
You clicked the "Back" button of your web browser after having successfully 
submitted changes, which is generally not a good idea (but harmless).
You entered the URL in the address bar of your web browser directly, which 
should be safe.
You clicked on a URL which redirected you here without your consent, in which 
case this action is much more critical.
Are you sure you want to commit these changes anyway? This may result in 
unexpected and undesired results"


So i uploaded it on my server and added a url to it.

Matthias

Re: Print to pdf fails on Windows with multiple pages

[Andreas Bergendal via use-livecode]

Hi Panos,

Interesting, I had not seen that bug report. Yes, it’s the same issue, and 
unfortunately it seems not fully solved in 9.6.x.

I tried using 9.6.7 rc 2 Win 32bit and built both a 32bit and 64bit standalone, 
but neither did any better really. They can sometimes succeed on first run to 
create the full pdf, but after that it seems Windows calls it a day and refuses 
to repeat the effort.

Since the stack/data is indeed confidential, I’ll make it available to you 
through other channels.

Best,
Andreas

Hello Andreas,

This sounds like this bug https://quality.livecode.com/show_bug.cgi?id=23088,
which should be fixed in LC 9.6.6 RC-1 and newer.

If this is not the case for you, could you attach a sample stack and the
pdf to this report and reopen it? Or send it to me directly if they are
confidential. Also, it might be worth checking with the 32bit version of LC
for Windows

Kind regards,

Print to pdf fails on Windows with multiple pages

[Andreas Bergendal via use-livecode]

Hi all,

TL;DR:
App/IDE crashes/fails when printing 30+ pages to single pdf, using Windows 10. 
Works fine on Mac. Windows memory issues?


Long version:
I have a stack/app where a crucial feature is printing to pdf.

Om Mac (LC 9.6.6 or 9.6.7 rc1) this works flawlessly with 156 posts, resulting 
in a 312 page pdf file (around 4Mb):

---
set the printScale to 0.714286 ## This matches the A4 proportion of the printed 
area
set the printMargins to 0,0,0,0

open printing to pdf tFilename ## tFilename has been defined earlier in the 
process

repeat for each line tLine in pKeyList ## pKeyList is a list of numerical keys
   fillFieldsWithData tLine ## This updates several fields on the card with new 
data from an array
   print card 1 from the topLeft of grc "page1" to the bottomRight of grc 
”page1” ## An A4-shaped rect
   print break
   print card 1 from the topLeft of grc "page2" to the bottomRight of grc 
”page2” ## An A4-shaped rect
   print break
end repeat

close printing ## (I also un/lock screen at appropriate places around this 
script, for speed)
---

On Windows 10, which is what my client is using, this happens:
- If run in the IDE, it sometimes manages to created the pdf, but usually fails 
(”printing failed” error), sometimes crashes LC silently
- If run as standalone, it can create a pdf with max 15-20 posts (2x pages), 
but if I try more then it stalls and fails, or crashes.

Another feature in the app is creating the 156 pdfs individually, and this 
works flawlessly also on Windows. 
So it’s creating the combined pdf that seems too taxing for poor old Windows, 
most of the time. The client needs both features to work.

Is this ”memory exhaustion” (saw that term mentioned by LCMark in the Forum on 
a different pdf problem)?

What can be done about it? Can I force Windows to dedicate more memory to my 
app?

I’ve tried having the pdf created on C:, on a USB stick and in SharePoint (the 
client’s preferred destination), but all fail equally.

Please advise! :)

Best,
Andreas

OK, so I guess it will work on Win 10, if that is what you are running, right?

Someone else knows if this works on Win >= 7?

thank you for your answers, which leaves some question however.

Is "Chrome" the web engine that LC is unsing in the "browser widget" on Windows?
Or do you create that browser with "revbrowseropen..."?

Re: Requirements for display PDF in a browser on Windows?

[Tom Glod via use-livecode]

I have definitely opened PDF in the browser in the past  and it opened
the default "chrome html 5" pdf reader.
everything seems to have worked.
And I don't see why it would no longer work now.
you can google "browser test" from within the browser and it will tell you
some info about the chromium based browser.
Some of it may shock you.

Cheers

Hi all,

the subject says it all, of course in regard of LC.

Is the web-plugin of Acrobat reader still neccessary?
Or do current Windows Browser display PDF files out of the box?

Re: PDF Viewer widget: expected experience from set the currentDestination?

[Keith Clarke via use-livecode]

I’m still struggling to find the Rosetta Stone for the PDF widget that connects 
the page & rect of any currentDestination with its link text on that page of 
the PDF, to enable recreation with scripting of the links that one sees 
out-of-the-box in PDF viewers such as Preview or Adobe.

I must have missed something as it would appear that the metadata peters out 
after one has established that a page ’n’ in the PDF document contains:
- via currentDestinations: none to maybe a few dozen links, each with part of 
an ‘href’ and it’s rect top-left corner defined, but no label text or page text 
start & end offsets;
- via hilitedRangeText: a chunk of plain text with no html or other ‘markup’ 
hints at what might constitute link text;
- ...and never the twain shall meet. 

If this is really the state of the art with the widget and its wrapping of 
PDFium, I can’t see how it can be scripted to work - so I think I’ll need to 
start looking elsewhere, outside of LC for a mechanism to access PDF text & 
links.

Please tell me I’m wrong and am missing something obvious?
Best,
Keith

Re: PDF Viewer widget: expected experience from set the currentDestination?

[Keith Clarke via use-livecode]

Thanks Monte - that code sorts the *calling* end of the recipe and the widget 
changes page to the one containing the currentDestination.

However, what about the *receiving* end of the recipe? Nothing seems to be 
happening upon arrival at the page to get any closer to this particular 
destination amongst the many on the same page. 

Where should one look to understand the options and handlers for the specific 
destination upon arrival *after* the change of page, re scroll into view, zoom, 
focus, setting the associated hilited text, etc?

Re: PDF Viewer widget: expected experience from set the currentDestination?

[Monte Goulding via use-livecode]

Hi Keith

Yes it does look like the currentDestination docs leaves a lot to be desired. I 
think there’s a couple of missing related items which is making the document 
display incorrectly. I’ve created an issue for that here 
https://quality.livecode.com/show_bug.cgi?id=23493

Here’s a simple example of using the currentDestination though:

local tDest
put "goto" into tDest["type”]
put "Fit" into tDest["mode”]
put 3 into tDest["page”]
set the currentDestination of widget “pdf" to tDest

Cheers

PDF Viewer widget: expected experience from set the currentDestination?

[Keith Clarke via use-livecode]

Hi folks,
Please can anyone share the response/experience to be expected in the PDF 
Viewer widget after a successful call to set the currentDestination?

I have the widget successfully changing currentPage when set but I was hoping 
to see some visual feedback with on a change of currentDestination - to perhaps 
highlight something or zoom or scroll the named destination into focus? 

Unfortunately, the dictionary entry for currentDestination doesn’t help as it 
has no examples and the description of as it seems to be missing chunks of 
critical text regarding the ‘receive’ end of the message... 

"This is the format that is sent as a parameter in the message and is used by 
the  and  and properties for goto type destinations:...”

Perhaps I’ve missed some settings on the widget to allow it to respond to this 
message?
TIA
Best,
Keith

Re: How to extract whole text from a PDF file with the PDF

Ah, OK thanks for the clarification. I hadn’t realize PDFium has been
around as long as it has been.
I wouldn’t sweat the naming conflict, there’s at least three “PDFKit”
libraries so you’re not alone.

Nope. My company (Researchware) and I paid for the development of the 
XPDF External shipped with LiveCode. Monte did the code for us when he 
was an independent LiveCode developer, paid directly by Researchware. It 
is based on the C++ "external" API template, calling the Google PDFium 
library. Researchware then transferred the license to LiveCode when 
Monte went to work for them. I called it XPDF because it was an eXternal 
for PDFs. I was unaware (at the time) for anything else using the XPDF

correcting me when I had a really stupid syntax specified)




The newer (> 9.6.3) PDF Widget is based on PDFium which is an offshoot
project that spawned from Google’s Chromium project. I’m not sure about the
licensing involved with that.

If you’re running macOS I released a (semi-complete) library that uses
Apple PDFKit (not to be confused with several other PDFKits that are out
there, such as this JS PDFKit: https://pdfkit.org ). That can extract text
from PDF, per-document or per-page.

At some point I may update that library, adding the ability to extract RTF
styled text and also make iso it can use UIView, which would make available
on iOS devices too, but I’m really busy right now so that’s not likely to
get attention from me anytime soon.

Note my "if".

In the next message in this thread Paul clarified that the component is
not derived from a GPL-governed work, so the rights and responsibilities

Re: How to extract whole text from a PDF file with the PDF

[Paul McClernan via use-livecode]

I was fairly certain that XPDF external was/is based on this XPDF:
https://en.m.wikipedia.org/wiki/Xpdf
Which has both GPL and Proprietary Licensing options available.

The newer (> 9.6.3) PDF Widget is based on PDFium which is an offshoot
project that spawned from Google’s Chromium project. I’m not sure about the
licensing involved with that.

If you’re running macOS I released a (semi-complete) library that uses
Apple PDFKit (not to be confused with several other PDFKits that are out
there, such as this JS PDFKit: https://pdfkit.org ). That can extract text
from PDF, per-document or per-page.

At some point I may update that library, adding the ability to extract RTF
styled text and also make iso it can use UIView, which would make available
on iOS devices too, but I’m really busy right now so that’s not likely to
get attention from me anytime soon.

RE: How to extract whole text from a PDF file with the PDF widget?

[Ralph DiMola via use-livecode]

Sorry I could not get back to you on this until now. (-1)s don't work here.

put 1 into tHilitedArray["from"]["page"]

  put 1 into tHilitedArray["from"]["index"]

  put 99 into tHilitedArray["to"]["page"]

  put 99 into tHilitedArray["to"]["index"]

  set the hilitedRange of control "PDF1" to tHilitedArray

  put the hilitedRangeText of control "PDF1" into tText

This will work if you don't need to know the page number. If you do then cycle 
thru each page. (1 to the NumberOfPages of control "PDF1")

We've just started to make a map from XPDF APIs to the PDF Widget APIs, so I'll 
make sure that gets done soon and add any missing capabilities as requests to 
the LC Quality Center.

With regard to the hilitedRange and hilitedRangeText properties, can you just 
advise on the correct use to get a PDF's text? i.e can you use a range of 1 to 
-1 to get the whole document text or would that just be the current page text?

Thanks in advance,

Note my "if".

In the next message in this thread Paul clarified that the component is 
not derived from a GPL-governed work, so the rights and responsibilities 
of the GPL do not apply here:

Re: How to extract whole text from a PDF file with the PDF widget?

[Monte Goulding via use-livecode]

Both the page and character index are clamped to the number of pages and 
characters on a page so you could set both to very high numbers. Adding 
character counts to the documentPages property might be useful here too.

That's why I jumped in on this thread - we HAVE to have the ability to extract

I suspect many other commercial developers who used the External still have

To migrate, all the command and functions of the External need to be mapped to

External in our code all of which need to be mapped, updated, and tested - so 
no trivial task.

Monte? LC 10.0.0 Dictionary does not list a property for the page text.

Re: How to extract whole text from a PDF file with the PDF widget?

[Monte Goulding via use-livecode]

Hi Folks

Currently you can extract text in the widget by setting the hilitedRange and 
getting the hilitedRangeText. It wouldn’t be that hard to add extracted text to 
the documentPages property. The PDF widget was built to meet the requirements 
for a client rather than to match the features of XPDF so it’s worthwhile 
anyone still using XPDF to take the time to audit their use and see if there’s 
any extra features required. If so please create feature requests for them. 
While XPDF will continue to function we intend to stop including it in LiveCode.

It is not xpdfreader. The XPDF Erternal AND the PDF Wdiget with Licecode 
are based on the Google PDFium Library. The first is C++ code using the 
External template to call the PDFium library APIs and the second is 
using LCB to do the same.

If it is that would be problematic, as the open source edition of 
xpdfReader is licensed under GPL, and LC no longer has an edition

I did post on how to extract text from PDF using the free xpdfReader and

I presume that with Pro this is simpler still.
hope that helps

Re: How to extract whole text from a PDF file with the PDF widget?

[Paul Dupuis via use-livecode]

Yes, I am familiar with the XPDF external (based on Google's PDFium 
library), having designed it and paid Monte to code it and then turned 
it over to LiveCode.


I was referring to the PDF Widget (also based on Google's PDFium), which 
should have a comparable property for fetching the text of a page. The 
LC dictionary does not list any property for returning the page text, so 
I assume that is a Dictionary/Documentation error and that Monte can 
tell us the correct property of the PDF widget that will return the text 
of a page.

Paul,

here on mac OS the dictionary of LC 10 DP1 definitely lists the function

Btw. checking this showed me that this function seems to be deprecated and

should be used.

Re: How to extract whole text from a PDF file with the PDF widget?

[Paul Dupuis via use-livecode]

There must be an undocumented property for the text of a page - there 
was a function to return the full text of a page in the External (XPDF) 
and to get the full text of the PDF file, you just stepped through the 
pages (1..N) getting and concatenating the page text.


Monte? LC 10.0.0 Dictionary does not list a property for the page text.

Re: How to extract whole text from a PDF file with the PDF widget?

[matthias rebbe via use-livecode]

Hi Torsten,

i think the PDF widget does not support extracting text by code. At least the 
documentation does not show any information about this.

You wrote, that you have a business license. That would mean, that you can use 
the Pro features of Livecode.
There is an external included in the Pro Feature Pack called XPDF. That 
external supports extracting text. Have a look at the function XPDFVIEWER_text.


Regards,

Matthias

How to extract whole text from a PDF file with the PDF widget?

[Torsten Holmer via use-livecode]

Hi,

I have a PDF file with text and pictures, but I just want the text.

I can do it manually with Ctrl-A and Ctrl-Copy by viewing the file with Preview 
on MacOS. 

I have a business licence and want to use the PDF widget but I cannot find a 
way to do it.

Can someone help me out?

Cheers,
Torsten

Re: PDF Viewer widget - how to enable interaction?

[Keith Clarke via use-livecode]

Thanks Monte. 

I should have been more explicit in that I’d tried that technique to handle the 
linkClicked message - none of the links in my test PDFs (that work in Preview 
and Adobe) fire it.

Assuming I’ve not missed any widget properties, it looks like there’s a problem 
with the underlying PDFium library not finding ‘clickables’ in the PDF 
documents - or the LC wrapping has a bug...

If navigation is under script control the documentation suggests that every 
‘clickable’ that works in any PDF viewer would need to be extracted into either 
the documentBookmarks or documentNamedDestinations arrays to be accessible for 
scripting - and both are empty for my ‘link-rich’ test PDFs.

Maybe the premium subscription for this widget means that it’s not been 
accessible for beta-testing by the user community, as I see nothing in the QA 
centre. 
Best,
Keith
