MMM-PDFSlideshow

I had some time today so I sat down and created something. Maybe useful. I’ll upload some Asterix-pdf to my mirror.

I’m happy with this status. If anyone needs modifications create a pull request. I’m not happy with the fullscreen behavior since the scaling does not work as expected (fullscreen always uses the full width, so a full page display is not nice in landscape orientation). But I do not really need this.

@chrisfr1976 cool. why fullscreen or if set to fullscreen position?

can be sized w css

@sdetweil Hi, this is the rest of my tries to show the page in 100% in fullscreen mode. So if position is set to a fullscreen region then also the fullscreen flag must be activated.

@chrisfr1976 cool, should be possible to control in fullscreen w css.

in car, does this support url to pdf, or just local file?
(just local file)

Hi,
now also hosted PDF-files are supported. PDF with url have now the lead. The local pdfs/ folder is the fall-back if no URL is set or in case of any errors.

But:
Most remote PDF is being blocked due to Cross-Origin Resource Sharing restrictions. The server hosting the PDF (https://www.w3.org/… etc.) is not allowing MagicMirror to access its resource. So the server-side PDF is downloaded locally and saved in a folder. Once the file exists locally, the download isn’t performed again. So if the server pdf is updated then the local download must be deleted.

• If a URL-PDF (or one single PDF) should be displayed change displayTime: 10000, to a higher value (avoid flickering)
• If a downloaded and local pdf should be displayed then copy or move the pdf from the pdfURL to pdfs folder and leave the URL in the config blank.

I think there are some optimizations in file handling possible and maybe a new PDF-URL can be sent with MMM-Remote module. But I won’t work on that any further. I will use the local folder in general (if I use the module at all - don’t know).

@chrisfr1976 have you looked at the cors server api we provide?

[chrisfr1976]

@sdetweil

Ö, no :)

Where?

[sdetweil]

@chrisfr1976 not well documented and not 100%

http://mm_server:mm_port/cors?url=…,
sendheaders=…,
receiveheaders=…

send/receive headers are headername:value,…

code in js/server_functions.js

for my readme support in mmm-config i had to fallback to curl/wget
