Open PDF from within CPG - work in progress - 1.4.10

[Hein Traag]

Guys and Gals from CPG.

I searched but seem to be unable to come up with the right search keywords for finding the mod
once made to open and browse pdf files within CPG.

Can someone point me in the right direction ?

Thanks
Hein

[Joachim Müller]

Browse pdf files directly in your gallery. (Warning: mod has originally been created for cpg1.3.x!)

[Hein Traag]

Thanks for the link GauGau. Will try to get it going on 1.4.10 , i'll see how far i get 

Hein

[Joachim Müller]

If you should manage to port it to cpg1.4.x, it would be great if you could post it for the benefit of others. If you decide to do so, please start a new thread (with reference to the old mod) and post your instructions on how to apply the mod in your new thread.

[Hein Traag]

I tried and tried but got nowhere. The code differs to much from 1.3 , for which it was originally written, for me to make it work.

It is a very handy mod though. Maybe somebody else, Nibbler maybe, can look at getting this to work for 1.4.x ?

Thanks
Hein

Hein can you try this cause I don't have access to my test bed :

1) open up the scripts.js and add the following at the end of that:

Code Select Expand


pos = 1;

function next(top)
{
pos +=1;
if (pos > top) pos = 1
repoint();
}

function prev(top)
{
pos -=1;
if (pos < 1) pos = top
repoint();
}

function repoint()
{
var picurl = document.getElementById("pdfview").src;
picurl = picurl.replace(/(\d+)\.jpg$/, pos + '.jpg');
document.getElementById("pdfview").src = picurl;
}


2) Open up themes/yourtheme/theme.php and add this function before ?> (php end tag)

Thanks Sami but unfortunately  :'(..it did not work.

Thanks for looking at the puzzle though. If you are willing to tackle this puzzle then i am willing to test it.

check the path to ghostscript under include/picmgmt.inc.php

Code Select Expand

$cmd = "/usr/bin/ghostscript -sDEVICE=jpeg -dNOPAUSE  -dBATCH -sOutputFile='{$CONFIG['fullpath']}edit/pdftmp.$filename.%d.jpg' '$image'";

also remove var_dump from themes/yourtheme/theme.php

[Hein Traag]

  Little woops on my side. The server i wanted to implement this mod on does not (yet) have ghostscript installed. Sysadmins are having a pow-wow now to determine if they want to install it.

When they do i will install this again to see if it works or not. Have not yet gotten time to install it on my test site.

Hein

- Ghost script installed now. But my dear Sysadmin forgot to pass me the path

I tried this on your gallery and had no problem having my default PDF reader opening your documents.

This was using Firefox 1.5.x and Foxit PDF Reader as default.

Bruce, read the thread more carefully. This deals with browsing a pdf file from within CPG without the use of pdf readers such as FoxIt PDF Reader.

[Hein Traag]

Sami,

got some testing done on my test bed. When i edit the files according to your post it looks good.. until i want to batch add some pdf files.
I then get nothing at first, it does not add the file to a album. When i then click reload it gives a message that it is has a unexpected $ at line 319.

Done the editing of the files three times now. Same result. Can you see what is going wrong ?

Sure I'll
Can you attache your picmgmt.inc.php to this thread , please

[Joachim Müller]

This mod appears to be a work in progress (as suggested in the subject) and far from being production-ready. It shouldn't have been moved to the mods section, as only actual working mods are suppossed to reside within this sub-board. Mod-discussion is not suppossed to reside in the mods board. I suggest moving this thread back to the support board where it was started initially and start a new thread with the mod instructions once you have fully figured out how the mod works and when it's ready-for-use. The new thread should then be moved to the mods board and contain a link to the previous discussion (this thread) that lead to the creation of the new mod.

Thanks

Joachim

My mistake. Please move as i can't.
