PDF Thumbnail images not displaying?

    From the FAQ, I’m referencing the below statement:

    “Here’s an example that displays a gallery of PDF documents, using the Google File Viewer to show the first page of each document as a thumbnail:”

    However, my media library is showing the default Adobe icon as the thumbnail and inserting the shortcode in my page there are no thumbnails when viewing the page itself as a user. It is just printing the filename as a link to the PDF.

    [mla_gallery post_mime_type=application/pdf post_parent=all link=file mla_viewer=true columns=3 orderby=date order=desc]

    (The only change I’ve made from the example is assigning 3 cols instead of your 1.)

    Does this require an additional plugin like Google File Viewer or anything? I know several other plugins I’ve been looking over require Imagick so I was assuming this plugin didn’t list that requirement because it was using some Google magic instead. Was I assuming incorrectly and still need Imagick?

    I see now I need size=icon in the shortcode and it displays the thumbnail instead of the link text. Is this correct? When I put it in my shortcode it displays the thumbnail on the page. I also see the mla_viewer=true appears to have no effect on my page with or without this part so I am thinking my issue has something to do with this and I don’t have the settings correct?

    Ok I see under settings The mla_viewer is not supported because:

    Imagick support is not installed.
    Ghostscript support is not installed.

    So my original suspicion was correct that this plugin still needs Imagick to work. I was hoping beyond hope that it was using some kind of Google support to handle that but I see now that isn’t the case.

    Marking as resolved. The culprit is imagick.

    Thanks for your question, the details of your application and for the time you took to test out and resolve the topic on your own.

    As you have verified, the Google File Viewer support was removed some time ago and Imagick/Ghostscript support replaced it. You can find some of the history in these topics:

    Thumbnails not displaying

    mla_gallery thumbnails are too small

    WordPress is emphasizing Imagick more with each new version, which was part of my motivation for using it.

    I have updated the obsolete statement you referenced in the Readme file. Thanks for alerting me; I regret the confusion it caused you.

    Thanks as well for your interest in the plugin.

    So one last quick question. I’ve been having some trouble getting GS and Imagick working correctly but I was wondering about a possible workaround.

    If I attach my own image as a custom field on the PDF, is there an option in your plugin to display that custom image? I know there is a mla_output option but I’m not thinking this where I would want to try this out.

    To be clear, I’m asking to go to Media -> Add New -> Add PDF -> Edit -> Add Custom field for image

    Then the plugin will display this image via an option instead of the icon or mla_viewer generated one.

    SIDENOTE: I do understand this is a highly inefficient solution and will require me to save a media file to serve as the image to another media file but at this point in time it’s a workable solution if possible. In the long term I understand I will need to figure out my imagick woes.

    Thanks for pressing ahead with the GS/Imagick installation. It took me a couple of tries to get it working on my hosted site, as outlined in this earlier topic:

    Featured Image for mla_viewer

    You wrote “If I attach my own image …” I have better news for you. Here is the excerpt from the “Thumbnail Substitution Support, mla_viewer” section of the Settings/Media Library Assistant Documentation tab:

    You can also assign a “Featured Image” to any Media Library item. For non-image items such as Microsoft Office documents the featured image will replace the MIME-type icon or document title in an [mla_gallery] display. Simply go to the Media/Edit Media screen, scroll down to the “Featured Image” meta box and select an image as you would for a post or page.

    If you have any trouble assigning a Featured Image for your documents, post an update and I will investigate.

    Ahh, yeah that is better news. I should have thought about the featured image first but the custom field section caught my eye first on the form and got me off track. That is certainly a viable solution at this moment. Thanks.
