Gif not saving properly
superjaja05 opened this issue · comments
Hello, i'm having an issue with gif saving
i load a gif using local base = vips.Image.new_from_file("base.gif", {n=-1}) , then i save it again using base:write_to_file("base2.gif") (just for testing)
And it seems that the base2 gif (the 2nd save) tries to "stack" the frames to save in file size, since nothing moves, but instead of actually stacking.. It just glitches out and become a transparent mess, any idea how i could fix that?
Hello @superjaja05, is this an old version of libvips? I tried with current stable (8.15.2):
$ vips copy base.gif[n=-1] base2.gif
$ vips --version
vips-8.15.2
To make:
I'm not sure how to check my version, but yes it might be an old version,
though i don't know how to update it (i use a fork of lua-vips, https://github.com/Bilal2453/lit-vips , but it hasn't been updated in a while and i don't know how to manually update it, if i even can)
What platform is this? If it's linux, just updating your OS should fix it.
Oh, if you're on windows, the regular lua-vips works pretty well now, there's no need to use a fork. It also supports plain lua as well as luajit.
I'm not sure if i can use lua-vips with luvit though?
@superjaja05 Luvit can handle Luarocks dependencies just fine as long as you have Luarocks set up - they just won't show up as dependencies if you ever package your project for lit. I've been using lua-vips with Luvit without issue for a while now.
If you really need lit support, it shouldn't be too hard to open a PR (or at least an issue) on the lit-vips repo.
Well the issue is i don't know how to use Luarocks, i always get errors and i can't figure out how to fix them
