at first view: works very fine!

question to other imagemagick/pdf-users here:

Please take an upload a pdf with more than one page - which page is displayed in the thumb? the first or the last?

Hi!

imagemagick always uses the first page.

Hi!

Hm, you are right. Strange, I could have sworn it was always the first page.

Try this patch:

Code: Select all

             $newSize = $r['width'] . 'x' . $r['height'];
             if ($fdim['mime'] == 'application/pdf') {
-                $cmd     = escapeshellcmd($serendipity['convert']) . ' -antialias -flatten -scale '. serendipity_escapeshellarg($newSize) .' '. serendipity_escapeshellarg($infile) .' '. serendipity_escapeshellarg($outfile . '.png');
+                $cmd     = escapeshellcmd($serendipity['convert']) . ' -antialias -flatten -scale '. serendipity_escapeshellarg($newSize) .' "'. serendipity_escapeshellarg($infile) .'[0]" '. serendipity_escapeshellarg($outfile . '.png');
             } else {
                 if (!$force_resize && serendipity_ini_bool(ini_get('safe_mode')) === false) {
                     $newSize .= '>'; // Tell imagemagick to not enlarge small images, only works if safe_mode is off (safe_mode turns > in to \>)

HTH,
Garvin

hm ...

Code: Select all

Konnte folgendes Programm nicht ausführen: "/usr/local/bin/convert -antialias -flatten -scale '130x130' "'/srv/xxx/uploads/intern/Einladung_Radtour_Juli_2009.pdf'[0]" '/srv/xxx/uploads/intern/Einladung_Radtour_Juli_2009.serendipityThumb.pdf.png'", Fehlermeldung: , Rückgabewert: 1

Hi!"

Hm, seems the qupotes would need to be adjusted:

/usr/local/bin/convert -antialias -flatten -scale '130x130' '/srv/xxx/uploads/intern/Einladung_Radtour_Juli_2009.pdf'[0] '/srv/xxx/uploads/intern/Einladung_Radtour_Juli_2009.serendipityThumb.pdf.png'

Now I tried this code with success:

Code: Select all

$cmd     = escapeshellcmd($serendipity['convert']) . ' -antialias -flatten -scale '. serendipity_escapeshellarg($newSize) .' '. serendipity_escapeshellarg($infile) .'[0] '. serendipity_escapeshellarg($outfile . '.png');

so I think it will get this command:

Code: Select all

/usr/local/bin/convert -antialias -flatten -scale '130x130' '/srv/xxx/uploads/intern/Einladung_Radtour_Juli_2009.pdf'[0] '/srv/xxx/uploads/intern/Einladung_Radtour_Juli_2009.serendipityThumb.pdf.png'

But honestly I do not know why it works with '/srv/xxx/uploads/intern/Einladung_Radtour_Juli_2009.pdf'[0]

http://www.imagemagick.org/Usage/files/ ... postscript says it has to be

Code: Select all

convert document.pdf'[0]'     first_page_of_pdf.gif

but I have:

but http://www.imagemagick.org/script/comma ... .php#input says:

Selecting Frames

Some images formats contain more than one image frame. Perhaps you only want the first image, or the last, or some number of images in-between. You can specify which image frames to read by appending the image filename with the frame range enclosed in brackets. Here our image (an animated GIF) contains more than one frame but we only want the first:

$magick> convert 'images.gif[0]' image.png

[Unix shells generally interpret brackets so we enclosed the filename in quotes above. In a Windows command shell the brackets are not interpreted but using quotes doesn't hurt. However, in most cases the roles of single-quotes and dowuble-quotes are reversed with respect to Unix and Windows, so Windows users should usually try double-quotes where we display single-quotes, and vice versa.]

ha, I think this would be the right code!

Code: Select all

                $cmd     = escapeshellcmd($serendipity['convert']) . ' -antialias -flatten -scale '. serendipity_escapeshellarg($newSize) .' '. serendipity_escapeshellarg($infile.'[0]') .' '. serendipity_escapeshellarg($outfile . '.png');

so we get

Code: Select all

/usr/local/bin/convert -antialias -flatten -scale '130x130' '/srv/xxx/uploads/intern/BriefOstern2009single1.pdf[0]' '/srv/xxx/uploads/intern/BriefOstern2009single1.serendipityThumb.pdf.png'

and all is within the quotes!

and now it would be fine to get the fix for the first problem (no thumbnail) for the gallery-plugin:

so that there is a thumbnail here, too:

http://www.sankt-joseph-siemensstadt.de ... 009-03-21/

(in the media library there is shown the thumbnail now.)

and another thing, related to the new functionality of pdf-thumbs:

selecting a pdf in the library I get the some options like for images, especially "thumb or the larger image?". Taking the thumb all works fine, now

But using larger image:

Code: Select all

<a class='serendipity_image_link' href='/uploads/Artikel/Gruppen/Ministranten/neue-minis-2009-joseph.pdf'><!-- s9ymdb:640 --><img width='1000' height='1000' style="border: 0px; padding-left: 5px; padding-right: 5px;" src="/uploads/Artikel/Gruppen/Ministranten/neue-minis-2009-joseph.pdf" alt="" /></a>

looks not realy good: a pdf as an image src

What is about this idea: no "thumb or larger image" but "thumbnail or text-link (as before the fix)"?

Very cool, Garvin, thanks!

After updating to the actual release of s9y I got the error again - unfortunately my last patch for this did not found his way to the repositry

@garvin: please change the convert command in include/functions_images.inc.php

Code: Select all

$cmd     = escapeshellcmd($serendipity['convert']) . ' -antialias -flatten -scale '. serendipity_escapeshellarg($newSize) .' '. serendipity_escapeshellarg($infile.'[0]') .' '. serendipity_escapeshellarg($outfile . '.png');

Please!
