Gifski r8/7/2023 ![]() ![]() The gifski() function combines a set of PNG images into a single animated GIF file: # Convert png files to gif The ?gifski manual page contains example of both. The R interface is very simple: either generate a GIF from a set of images, or directly from the R graphics device. If you are on MacOS, try installing from source to see how it works: install.packages("gifski", type = "source") Cargo automatically compiles and links all Rust code when building the R package. ![]() On Linux you need to install cargo to compile the rust code, but the package does not require any external libraries. One of the major benefits of Rust is that it has no runtime, so the R package has no dependencies. The R package wraps the Rust crate and can be installed in the usual way from CRAN. The Gifski Website has more technical details and beautiful examples. It can create animated GIF images with thousands of colors per frame and do so much faster than other software. Gifski is a multi-threaded high-quality GIF encoder written in Rust. ![]() Gifski is a simple but powerful package which can hopefully take away an important performance bottleneck for generating animated graphics in R. cargo gcc - shared - L / home / hb / shared / software / CBI / R - 4.0.4 / lib / R / lib - L / usr / local / lib - o gifski.so wrapper.o - Lmyrustlib / target / release - lmyrustlib - lresolv - pthread - L / home / hb / shared / software / CBI / R - 4.0.4 / lib / R / lib - lR installing to / home / hb / R / x86_64 - pc - linux - gnu - library / 4.The gifski package which was demonstrated in May at eRum 2018 in Budapest is now on CRAN. 50s rm - Rf / tmp / hb / Rtmprkf9QB / R.INSTALL6d751a9adcf6 / gifski / src /.
