Expand description
Glycin allows to decode images into gdk::Textures and to extract image
metadata. The decoding happens in sandboxed modular image loaders that have
to be provided as binaries. The glycin-utils for more
details.
§Example
You need to enable the gdk4 feature for this example to work.
let file = gio::File::for_path("image.jpg");
let image = Loader::new(file).load().await?;
let height = image.info().height();
let texture = image.next_frame().await?.texture();You can pass the texture of a Frame to
gtk4::Image::from_paintable() to display the image.
§External Dependencies
Glycin requires the libraries libglib2.0, liblcms2, libfontconfig, and
libseccomp packages to be installed. For the gdk4 feature, libgtk-4 is
required as well. To actually work with images, loaders for the respective
formats have to be installed. Glycin provides loaders for many formats
that are packaged with many distributions. When working in the default
sandbox mode, the bwrap binary of bubblewrap is required as well. The
required dependencies can usually be installed through commands like
$ apt install libgtk-4-dev liblcms2-dev libfontconfig-dev libseccomp-dev glycin-loaders bubblewrapon Debian/Ubuntu or
$ dnf install gtk4-devel lcms2-devel fontconfig-devel libseccomp-devel glycin-loaders bubblewrapon Fedora.
§Features
gdk4— Enables interoperability withgdk4by enabling to get agdk::Texturedirectly.tokio— Makes glycin compatible withzbususingtokio.
