Request support for http://www.e-rara.ch ? about dezoomify HOT 16 CLOSED

Well, then let's open it again

from dezoomify.

Hi,
I looked at the site, they use openlayers, which is not supported by dezoomify. I may add support for this later, but I currently don't have the time.

For the commandline, tool, I added a video to the documentation. If it's still not clear, don't hesitate to ask questions.

from dezoomify.

Oke, I understand.

Now I still got problems with dezoomify via cmd on Win10. I keep gettings error when installing dependies.

Installing node-canvas on windows isn't straightforward, but they provide a HOWTO: https://github.com/Automattic/node-canvas/wiki/Installation---Windows

Or you could just install a linux virtual machine...

from dezoomify.

Tried Ubuntu in Vmware with no luck. Getting similar errors with canvas this.. cairo that..
I give up.

Thanks anways!

from dezoomify.

Please, just try this on your VM before giving up:

curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
sudo apt-get install nodejs libcairo2-dev libjpeg8-dev libpango1.0-dev libgif-dev build-essential g++
git clone https://github.com/lovasoa/dezoomify.git
cd dezoomify/node-app
npm install
node dezoomify-node.js "http://www.hyper-photo.com/hyperpano/babel17/" "babel17.jpg"

Just enter your password when asked to do so.

from dezoomify.

That works! Thanks! However, it takes me several re-tries to load all tiles completely. Big files seem to hang around 90% when loading those tiles. Raising VM ram and increasing CPU cores don't help.

Do u have any tips?

from dezoomify.

You should open another issue about that. I'll investigate this when I'll have time. I suspect it's because we load the first tiles too fast, making the server's latency increase.

Sorry for getting offtopic. But now u have mentioned server latency, I tried to decrease VMware's bandwidth from Unlimited to 10 Mbps and voila, no issues anymore. This also fixed the ''Request failed, retrying'' messages I was getting quit often when loading the tiles.

Thanks!

from dezoomify.

That's a clever idea! I still have to patch dezoomify itself in order for the issue not to be here in the first place, though.

e-rara (Schweizer Bibliotheken)
    Beispielseite: http://www.e-rara.ch/zut/content/pageview/102788 (Bildnummer: 102788)

Ok, thank you. I'm closing this issue, then.

from dezoomify.

Yep it seems to work: http://www.e-rara.ch/download/webcache/0/2748118

from dezoomify.

The webcache file is NOT the highest quality available from them. You will see why as soon as you press the zoom icon. This will generate far superior quality.

But sadly 'Generic dezoomer' does not work well with e-rara.ch. It just keeps loading the tiles.

from dezoomify.

e-rara.ch as well as e-manuscripta.ch are supported by the VLS dezoomer now

from dezoomify.

It now works thanks to the work of @1-Byte . So I'm closing this issue.
