embedded pdf viewer

I'm considering using jAlbum. I want to include some pdf files in amongst images and videos. Is there a way to view the contents of a pdf "in place" in an album? I did a quick test locally and the pdf opened separately in the browser. Perhaps there is a pdf-viewer plugin? I tried to find one, but could not find a complete list of available plugins. Lastly, is this the kind of thing that could be done in a plugin? I am an experienced java developer, perhaps I could give it a shot. Thanks.

I believe that all of the bundled skins show PDF's in the album, not in a new browser window.
Had to double-check that. There are several bundled skins that don't handle this gracefully, to wit, Minimal, Plain, and Zigzag. |

I was originally thinking of something that would work in the "grid" view, but now that I think about it more, I see that is not very practical. The examples you point to are very helpful, thanks.

The "grid" view refers to the layout of the thumbnails. Those are just JPG thumbnails, regardless of what they take the visitor to. An image has a thumbnail, a video has a thumbnail, a PDF has a thumbnail, and so on. But the visitor doesn't see "the real thing" until he clicks on the thumbnail. |

That’s naturally room for improvement. I might put it on the todo to generate thumbnail images of the first page of pdf documents.

That's what the THM mechanism is supposed to address. What should be on the todo list is to clean up all of that, so that you can just choose a representing image for any album object, rather than going through the routine of creating a file with the same base name and a fake extension. And with objects that are linked, rather than copied, getting the THM to work is a challenge. |

Yes, it should be simplified. |

I'm a bit surprised this doesn't exist. Is there maybe a plugin for it? Or even something outside of jAlbum? Does anyone know of such a thing? |

There are plenty of online conversion tools that can convert a PDF into a series of JPG's, one image per page, like this site:
https://convertio.co/
But there probably isn't a Java utility for doing it, which is what jAlbum must have. |

Actually, there is: https://pdfbox.apache.org/. It includes a command line utility that seems to (basically) work, so I can use it to generate jpg/thm files.
But I'm wondering how difficult this would be to integrate into jAlbum. I am a Java developer -- is this the kind of thing that could be done in a skin? Or in a plugin? |

The easiest way would be to make an external tool to run on a project before making the album. Next would be to make a plugin. Doing it within a skin would not be easy, need the developer to adopt it and would only work, if it did at all, for that skin (or family of skins).

I think we'd need to integrate this functionality within jAlbum itself. I can have a peek at pdfbox. Would it be fine to simply have jAlbum generate a thumbnail image from the 1:st page of a pdf file?

Pdfbox doesn’t seem to be able to generate an image of a page with no images, I might have missed an api call for that but didn’t see anything obvious. |
