将屏幕截图另存为R Selenium中的变量

我试图将Selenium的屏幕截图存储到一个变量中，以便计算出它的高度：

library(RSelenium)
library(magick)
server <- remoteDriver(remoteServerAddr = "localhost",
                      port = 4444,
                      browserName = "firefox")
server$open()
server$navigate("https://google.com")
screenshot <- server$screenshot(display = FALSE)
image_info(screenshot)

库（RSelenium）
图书馆（magick）
服务器终于找到了它：

library('base64enc')

# this returns a list of base64 characters
screenshot <- server$screenshot(display = FALSE)

# converts the base64 characters into a vector
screenshot <- base64decode(toString(screenshot), output = NULL)

# reads the vector as stores it as a PNG
screenshot <- image_read(screenshot)

library（'base64enc'）
#这将返回base64字符的列表
截图
library('base64enc')

# this returns a list of base64 characters
screenshot <- server$screenshot(display = FALSE)

# converts the base64 characters into a vector
screenshot <- base64decode(toString(screenshot), output = NULL)

# reads the vector as stores it as a PNG
screenshot <- image_read(screenshot)
