问题 Support for gzip in JavaScript is surprisingly weak. All browsers implement it for supporting the Content-encoding: gzip header, but there is no standard access to the gzip / gunzip function of the browser. So one must use a javascript only approach. There are some old gzip-js libraries around, but they don't seem stream-enabled and 6 years out of maintenance. Then there is pako, more actively maintained, but that also doesn't seen stream enabled if using their own distribution, so you need

Have attempted to do a modification of the sample [recommend viewing source on that] that JSZip provides: <!DOCTYPE HTML> <html> <head> <link href="https://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.1/css/bootstrap-combined.min.css" rel="stylesheet"> <link href="https://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.1/css/bootstrap-combined.min.css"

After some searching here on StackExchange, I came up with this code: var zip = new JSZip(); // Create the object representing the zip file // ...Add the data and images console.log('Generating compressed archive...'); zip

问题 I am using JSZip to make a program that generates the image data from a canvas element and puts the image into a zip file. Right now, it is turning the canvas image into an DataURL. Then, I get rid of the part of the resulting string that says data:image/png;base64, . Now, there is nothing left but the base64 data. I then use atob to change it to ascii. It seems like putting the remaining string into an image file should work, but the generated ascii text is not correct. Many parts of it are
