# magick ![](http://www.textfiles.com/underconstruction/HeHeartlandPark2601underconstructionbar9.gif) ##### *Advanced Image-Processing in R* [![Build Status](https://travis-ci.org/ropensci/magick.svg?branch=master)](https://travis-ci.org/ropensci/magick) [![AppVeyor Build Status](https://ci.appveyor.com/api/projects/status/github/ropensci/magick?branch=master&svg=true)](https://ci.appveyor.com/project/jeroen/magick) [![Coverage Status](https://codecov.io/github/ropensci/magick/coverage.svg?branch=master)](https://codecov.io/github/ropensci/magick?branch=master) [![CRAN_Status_Badge](http://www.r-pkg.org/badges/version/magick)](https://cran.r-project.org/package=magick) [![CRAN RStudio mirror downloads](http://cranlogs.r-pkg.org/badges/magick)](https://cran.r-project.org/package=magick) [![Github Stars](https://img.shields.io/github/stars/ropensci/magick.svg?style=social&label=Github)](https://github.com/ropensci/magick) > Bindings to ImageMagick: the most comprehensive open-source image processing library available. Supports many common formats (png, jpeg, tiff, pdf, etc) and manipulations (rotate, scale, crop, trim, flip, blur, etc). All operations are vectorized via the Magick++ STL meaning they operate either on a single frame or a series of frames for working with layers, collages, or animation. In RStudio images are automatically previewed when printed to the console, resulting in an interactive editing environment. ## Documentation About the R package: - [vignette: The magick package: Advanced Image-Processing in R](https://cran.r-project.org/web/packages/magick/vignettes/intro.html) - [rOpenSci Community Call (recording)](https://vimeo.com/channels/rocommunitycalls/180799058) About the underlying library: - [Magick++ Tutorial](https://www.imagemagick.org/Magick++/tutorial/Magick++_tutorial.pdf) - [Magick++ STL Documentation](https://www.imagemagick.org/Magick++/STL.html) ## Hello World **Run examples in RStudio** to see a live previews of the images! If you do not use RStudio, use `image_browse` to open images. On Linux you can also use `image_display` to get an X11 preview. ```{r eval = FALSE} library(magick) frink <- image_read("https://jeroen.github.io/images/frink.png") image_trim(frink) image_scale(frink, "200x200") image_flip(frink) image_rotate(frink, 45) ## <-- result of this is shown image_negate(frink) frink %>% image_background("green") %>% image_flatten() %>% image_border("red", "10x10") ``` ```{r eval = FALSE, include = FALSE} image_rotate(frink, 45) %>% image_write("img/frink-rotated.png") ``` ![](img/frink-rotated.png) Effects ```{r eval = FALSE} image_oilpaint(frink) image_implode(frink) image_charcoal(frink) ## <-- result of this is shown image_blur(frink) image_edge(frink) ``` ```{r eval = FALSE, include = FALSE} image_charcoal(frink) %>% image_write("img/frink-charcoal.png") ``` ![](img/frink-charcoal.png) Create GIF animation: ```{r eval = FALSE} # Download images oldlogo <- image_read("https://developer.r-project.org/Logo/Rlogo-2.png") newlogo <- image_read("https://www.r-project.org/logo/Rlogo.png") logos <- c(oldlogo, newlogo) logos <- image_scale(logos, "400x400") # Create GIF (animation1 <- image_animate(logos)) image_write(animation1, "img/anim1.gif") # Morph effect <-- result of this is shown (animation2 <- image_animate(image_morph(logos, frames = 10))) image_write(animation2, "img/anim2.gif") ``` ![](img/anim2.gif) Read GIF anination frames. See the [rotating earth example GIF](https://upload.wikimedia.org/wikipedia/commons/2/2c/Rotating_earth_%28large%29.gif). ```{r eval = FALSE} earth <- image_read("https://upload.wikimedia.org/wikipedia/commons/2/2c/Rotating_earth_%28large%29.gif") length(earth) earth[1] earth[1:3] earth1 <- rev(image_flip(earth)) ## How Austrialans see earth image_write(earth1, "img/earth1.gif") ## <-- result of this is shown ``` ![](img/earth1.gif) R logo with dancing banana ```{r eval = FALSE} logo <- image_read("https://www.r-project.org/logo/Rlogo.png") banana <- image_read("https://jeroen.github.io/images/banana.gif") front <- image_scale(banana, "300") background <- image_scale(logo, "400") frames <- lapply(as.list(front), function(x) image_flatten(c(background, x))) image_write(image_animate(image_join(frames)), "img/Rlogo-banana.gif") ``` ![](img/Rlogo-banana.gif) ## Installation Binary packages for __OS-X__ or __Windows__ can be installed directly from CRAN: ```r install.packages("magick") ``` Installation from source on Linux or OSX requires the imagemagick [`Magick++`](https://www.imagemagick.org/Magick++/Documentation.html) library. On __Debian or Ubuntu__ install [libmagick++-dev](https://packages.debian.org/testing/libmagick++-dev): ``` sudo apt-get install -y libmagick++-dev ``` On __Fedora__, __CentOS or RHEL__ we need [ImageMagick-c++-devel](https://apps.fedoraproject.org/packages/ImageMagick-c++-devel). However on CentOS the system version of ImageMagick is quite old. More recent versions are available from the [ImageMagick downloads](https://www.imagemagick.org/download/linux/CentOS/x86_64/) website. ``` sudo yum install ImageMagick-c++-devel ```` On __OS-X__ use [imagemagick@6](https://github.com/Homebrew/homebrew-core/blob/master/Formula/[email protected]) from Homebrew. Note that we need to build `--with-fontconfig` to support text features such as annotation and svg rendering. ``` brew reinstall imagemagick@6 --with-fontconfig --with-librsvg ``` There is also a fork of imagemagick called graphicsmagick, but it doesn't work as well. I highly recommend you build with imagemagick. [![](http://www.ropensci.org/public_images/github_footer.png)](http://ropensci.org)
