Way to enforce --tile-width and --tile-height ? about libvips HOT 19 CLOSED

DeepZoom always has tiny edge tiles, you have to have it that way or the viewers won't work.

You're right, the google maps option turns on a thing to round edge tiles up to full-size. It has a different system for numbering tiles though.

I am trying to use Leaflet [ http://leaflet.cloudmade.com/ ] which is originally designed for maps so it might be better choice for me altogether even though I was to use it to display eslides from microscope. I will try to compile from Git clone (even though in Git it seems to still be on 7.30) and have a look at the different file numbering system then. Again thanks for such a speedy response I wish more people were like you :)

I'm supposed to be writing, so any distraction is welcome :-(

I did a test microscope slide using zoomify:

It seems to work, though leaflet looks nicer.

from libvips.

Yep, that is something I am trying to achieve. I wanted to use Zoomify or OpenSeadragon first, but then found Leaflet and almost fell in love with it. All the plugins, it works on mobile, supports multitouch on phones and tablets, can implement drawing on the slides, even 3d objects.

Well anyways,
I have compiled the git version (thanks to your help yesterday), and it seems to work fine even though it is printing ** DEBUG_FATAL every time.
But I can't find the GoogleMap class or package, neither deep zoom, is there some documentation I am not reading?
What are you writing? A book?

from libvips.

Hi, configure with --disable-debug to stop the FATAL messages. Odd-numbered releases (eg. 31) default to all debugging enabled.

Use dzsave with --layout to make google maps format:

$ vips dzsave fred.jpg x --layout google

or --layout zoomify to make that format. I've not tested the google maps writer, I just tried to implement the spec I found somewhere. Let me know if it's broken.

Just writing part of a paper, very boring.

Finaly had time to try it again. I works great. I generates white background where it needs to. Is there a way to change the colour or perhaps set the transparency in case of PNG?

from libvips.

No, it's white only. I'll look at adding an option.

from libvips.

Would picking black or white be enough? Or do you need to be able to set specific colours?

from libvips.

I added a thing to let you specify any colour:

jcupitt@2f65b07

eg.

vips dzsave k2.jpg x --layout google --background "1 2 3"

For PNG, set transparency by giving four numbers, RGBA. Numbers are decimal.

from libvips.

Awesome! Thanks! Pulling and recompiling now, will report soon.

from libvips.

Well.. I don't know what I did but vips doesn't run now.
I rm -Red ~/libs/vips and then configured with prefix, made and installed but now I am getting:

$ vips --version
vips: error while loading shared libraries: libtiff.so.5: cannot open shared object file: No such file or directory

I checked libtiff and libtiff-dev but both are there:

$ sudo apt-get install libtiff4 libtiff4-dev
Reading package lists... Done

libtiff4 is already the newest version.
libtiff4-dev is already the newest version.

I will try, if I dcan figure out why, to check out older commit and compile that and see if that works.

from libvips.

Ok, I checked out dee1aac and compiled and have the same issue, so far have no clue what happened :( Will report any new findings.

from libvips.

I think you may have deleted the old vips incorrectly. Probably it should have been rm -rf ~/vips?

Nuke from orbit and try again:

rm -rf ~/vips
./configure --prefix=/home/fuho/vips
make
make install

and check that PATH and LD_LIBRARY_PATH contain "/home/fuho/vips/bin" and "/home/fuho/vips/lib" respectively.

Since I am having issues with cleaning after my installs I created a virtual pc running Ubuntu 12.04 Server edition and made a snapshot right before firts login after finished installation. After each unsuccessful install I revert to that snapshot and run the script like this again.

curl -L http://goo.gl/vsvh5 | sudo bash

This is where I am testing a script I wrote which should install libvips with support for openslide from github repos. You can see the script in a gist here https://gist.github.com/3870223, but I still don't have luck getting it to work.
I keep getting:

vips: error while loading shared libraries: libvips.so.29: cannot open share object file: No such file or directory

I am installing it as sudoed user without --prefix. I spent over 17 hours on it today to no avail, will continue tomorrow.
Maybe I am making some obvious mistakes, please look at the gist and let me know if you see something.

from libvips.

Oh dear, you must be making some small mistake, this should be very easy.

It sounds like it can't find the libvips library. Check the file is there and readable, then check what areas your system is searching. "ldd" is handy for seeing what libraries are being loaded. Try:

ldd `which vips`

to see what libs vips is looking for. Check that it's finding the ones it should from /usr/local/lib.

I would avoid building directly from git master. People try to keep it working, but it's not always 100%. I would pick a known-good point in the repository and make a tarball. Build from that and you'll be safe from anyone upstream making an error.

I would also build to a place in my home directory, if possible. Is there a strong reason to build to /usr/local?

from libvips.

The reason behind building this as a root without prefix is that eventually I will be installing this on servers and would like all users to be able to use it.
I am installing from git repo because I need deepzoom and google maps export. I also need support for the latest openslide that's why I am compiling openslide just before, also from github.
I can add checkouts of known commit before i attempt to configure and see if it helps. My whole life I have avoided learning C hoping it will just go away one day, but every so often it bites me in the ass :) I guess at least scratching the surface will be unavoidable, or learning how exactly gcc, configure and make works.
I will run the script on a vanilla virtual pc and try ldd as you mentioned.

Looks like

sudo ldconfig

fixed that :)
