Hello @piface314,
Your example works for me:
john@kiwi:~$ luajit
LuaJIT 2.1.0-beta3 -- Copyright (C) 2005-2017 Mike Pall. http://luajit.org/
JIT: ON SSE2 SSE3 SSE4.1 BMI2 fold cse dce fwd dse narrow loop abc sink fuse
> vips = require 'vips'
> image = vips.Image.text("Hello <i>World!</i>", {dpi = 300})

My guess would be that libvips failed to find the various libraries it needs to enable text rendering during configure
. Check the output carefully and keep adding dependencies until you see yes
in the summary table at the end. pangoft2-dev
is probably the main one.
What platform are you using?
I'm using Ubuntu 20.04. It's weird that I checked for pango before installing, it seems to be there:
$ apt search pangoft2
Sorting... Done
Full Text Search... Done
libpangoft2-1.0-0/focal,now 1.44.7-2ubuntu4 amd64 [installed,automatic]
Layout and rendering of internationalized text
Is it the wrong package? Now that you said it, I really noticed that running ./configure
again showed that it's missing:
...
text rendering with pangoft2: no
You need the -dev package to get the headers for compilation.
Ubuntu 20.04 comes with an OK libvips, I would just use that unless you have a very strong reason to make your own.
Oh, I wasn't aware of that. How should I properly remove this current misconfigured installation? Is enough to just delete the binaries? At /usr/local/bin/vips
and /usr/local/bin/vips-8.10
.
You can do make uninstall
, as long as you've not touched the libvips area since you did make install
.
Otherwise, I'd do:
find /usr/local/ -name "*vips*"
And remove everything that looks vipsy.
Thanks! That solved it, and now I'm using vips 8.9.1 which is in apt
.
Closing, since the issue has been solved.
Nice job clearing the weeds @rolandlo !
I recently installed vips-8.10.5, and tried rendering text, but I got an error:
(this is the example taken from README, run in luajit interactive mode)
I installed vips with just
./configure && make && sudo make install && sudo ldconfig
. Did I miss something? Is there a proper way to uninstall and try again, maybe trying an older version?
