Package scrap is a Go wrapper around the Rust https://github.com/quadrupleslap/scrap library. It supports reasonably fast capturing of raw screen pixels. The library dependency is only at compile time and statically compiled into the binary. Since go-scrap statically links the Scrap library, the scrap-sys subdirectory Rust project must be built in release mode before compiling this project. See the README at https://github.com/cretz/go-scrap for more info.
Readme
go-scrap is a Go wrapper around the Rust scrap library. It supports reasonably fast capturing of raw screen pixels. The library dependency is only at compile time and statically compiled into the binary. It works on Windows, Linux, and macOS.
Obtain the library, e.g. use go get with -d to not install yet:
go get -d github.com/cretz/go-scrap
Now, the Rust subproject scrap-sys must be compiled which is glue between the Go library and the Rust library. With
Rust installed, this can is done by running the following in the scrap-sys/ subdirectory:
cargo build --release
Note: On Windows this must use the same gcc that Cgo would. Go does not support MSVC-compiled libraries
yet. The easiest way to ensure this is with rustup by running
rustup default stable-x86_64-pc-windows-gnu before building.
Note: On Linux this needs the X11 XCB libraries with the Shm and RandR extensions. On Ubuntu (18.04+ since RandR must
be >= 1.12) they are packages named libx11-xcb-dev, libxcb-shm0-dev, and libxcb-randr0-dev respectively.
Now that the dependency is built, the library can be built. For example, take a screenshot:
go run ./example/screenshot
See the Godoc for more documentation and examples.
