Extension talk:PDFThumbnails

How to preview a different page (page 2) from a pdf?

Extension fails

 * Erreur lors de la création de la miniature : Error: /VMerror in --]--
 * VM status: 2 12510916 12525816
 * Current allocation mode is local

Same here (MW 1.19, PDFThumbnails 1.5)
When uploading a PDF-file (for instance here 'Ei2013-J4.3.1_Kompilieren_(CPP).pdf') I get the following instead of a preview). Translation (+/-):

Error while creating preview: convert: no decode delegate for this image format `//local-backend/local-public/b/be/Ei2013-J4.3.1_Kompilieren_(CPP).pdf' @ error/constitute.c/ReadImage/532. convert: missing an image filename `JPG:/tmp/transform_3c798e2-1.jpg' @ error/convert.c/ConvertImageCommand/3011.

Help would be greatly appreciated!

Syntax unclear
How is it supposed to work? What syntax to use? Thanks, Hikey

Yes, I need to know the syntax too, Thanks. Holger
