Hello World fails

[stuta]

Hello. Great library!

All other examples work (osx x64), but vips.Image.text fails.

-- make a new image with some text rendered on it
image = vips.Image.text("Hello World!", {dpi = 300})

error: 'no such operation
VipsOperation: class "text" not found
'

Hello, vips uses pangoft2 to render text, so you need to enable that.

The brew vips should work, I think.

Thanks, I realized that too.

Tool to change loader paths (huge job by hand): https://github.com/auriamg/macdylibbundler

• I changed Settings.cpp #63 to std::string inside_path_str = "@loader_path/";

You shouldn't need to change loader paths. I tried here and it all works fine:

brew install lua
brew install luajit
brew install vips
luarocks --local install lua-vips
eval `luarocks path`

Then:

$ luajit

>  vips = require "vips"
> x = vips.Image.text("hello world")
> x:write_to_file("x.png")
> ^D
$ open x.png

And I can see a "hello world" image.

I don't use luarocks for client installation. I have all libs in my own folder (mac32/64 + linux64/arm + win 32/64). Would be nice to have 32 bit win libraries, compiling them in paiful and non-productive work.

[jcupitt]

There are some old win32 builds here:

http://www.vips.ecs.soton.ac.uk/supported/8.1/win32/

But they might be too old.

Did you get it working with luajit on win64? I've not tried that myself.
