在R中将Base64转换为PNG/JPEG文件

我想做的和你做的完全相反.我将图像的base64存储在变量"capimg"中，现在我想将其转换为png或jpeg文件.您能帮我对流程进行逆向工程吗?这可行吗?我已经看到使用php来完成此操作，如下所示，但我需要一个R脚本来完成该操作<?php$data = urldecode($_POST['imageData']);list($type, $data) = explode(';', $data);list(, $data) = explode(',', $data);$data = base64_decode($data);file_put_contents('image.png', $data);?>实际上，我还可以使用base64enc包将base64解码为向量，如下所示y<-base64decode(capimg)但是我不知道该怎么做解决方案这对我有用:library(base64enc)enc <- base64encode("images.jpg")conn <- file("w.bin","wb")writeBin(enc, conn)close(conn)inconn <- file("w.bin","rb")outconn <- file("img2.jpg","wb")base64decode(what=inconn, output=outconn)close(inconn)close(outconn) images.jpg由Wikipedia提供，该维基百科可从I have seen the process to convert a png file to base64 work in the post belowConvert R image to Base 64I would like to do the exact opposite of what you did. I have a base64 of a image stored in a variable "capimg" and now I want to convert it into a png or jpeg file. Can you help me reverse engineer the process.Is this doable?I have seen this done using php like below but I need a R script to do the same<?php$data = urldecode($_POST['imageData']);list($type, $data) = explode(';', $data);list(, $data) = explode(',', $data);$data = base64_decode($data);file_put_contents('image.png', $data);?>In fact I am also able to decode the base64 into a vector using the base64enc package like belowy <- base64decode(capimg)But I do not know how to proceed any further 解决方案 this works for me:library(base64enc)enc <- base64encode("images.jpg")conn <- file("w.bin","wb")writeBin(enc, conn)close(conn)inconn <- file("w.bin","rb")outconn <- file("img2.jpg","wb")base64decode(what=inconn, output=outconn)close(inconn)close(outconn)images.jpg courtesy of Wikipedia accessed from here 这篇关于在R中将Base64转换为PNG/JPEG文件的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
