kandi X-RAY | zopfli Summary

zopfli is a C++ library typically used in Utilities, Compression applications. zopfli has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

Zopfli Compression Algorithm is a compression library programmed in C to perform very good, but slow, deflate or zlib compression. The basic function to compress data is ZopfliCompress in zopfli.h. Use the ZopfliOptions object to set parameters that affect the speed and compression. Use the ZopfliInitOptions function to place the default values in the ZopfliOptions first. ZopfliCompress supports deflate, gzip and zlib output format with a parameter. To support only one individual format, you can instead use ZopfliDeflate in deflate.h, ZopfliZlibCompress in zlib_container.h or ZopfliGzipCompress in gzip_container.h. ZopfliDeflate creates a valid deflate stream in memory, see: ZopfliZlibCompress creates a valid zlib stream in memory, see: ZopfliGzipCompress creates a valid gzip stream in memory, see: This library can only compress, not decompress. Existing zlib or deflate libraries can decompress the data. zopfli_bin.c is separate from the library and contains an example program to create very well compressed gzip files. Currently the makefile builds this program with the library statically linked in.

            How to decompress an object compressed by zlib in JavaScript?
            Asked 2021-Apr-11 at 08:55

            In JavaScript project, I want to decompress an object compressed by zlib(Zopfli.js) and I'm trying it with pako.min.js. However, the example at the official site of pako uses require function which does not exist in JavaScript. Maybe Node.js has this but I'm afraid it would take a lot of time and pains to combine this JavaScript project with Node.js, because I know nothing about Node.js.

            Is it any way to get through with this, or another way to decompress the object?

            Any information would be appreciated.

            What I've already tried

            The problem is you're using a 32-bit version of Python 3.6, for which there aren't wheels (binary versions) for that version of mysqlclient.

            You can see here in the package file list that there is a Windows x32 wheel for 1.3.12 – try that.

            This was actually a problem with the capitalization of the files.

            The kernel source I had received from the manufacturer (Lenovo) had many files in the netfilter directory that had different capilization than what was excepted by the build tools. Changing the capitalization got around these errors.

            First of all, the bc application have to exists in at least two different directories.

            It seems to me like the PATH variable from your shell or system is configured wrong so it first finds the wrong bc application first.

            Answered 2017-Dec-10 at 12:41

            It seems that your node-gyp requires java to be built correctly. The thing with Heroku's architecture is that it only provides you what you specify/need. Right now I don't think Heroku understands that it needs a JVM to run your application. So you should provide a buildpack. A build pack put very simply is a set of rules telling Heroku what to set-up, install and build. There is a buildpack for JVM called heroku/jvm. So, what you have to do is add this to your application through the dashboard or your CLI via heroku buildpacks:add heroku/jvm.

            There is one more thing to do. Since your app requires javac at build time itself, we should pull up the build order for java/jvm . So in that case you should probably do heroku buildpacks:add --index 1 heroku/jvm. This puts the JVM buildpack at position 1 and pushes every other buildpack down the order.

            Now when the app starts building, it first sets up the JVM (thus enabling javac for your instance) and then runs the NodeJS build. This build will now pick up the javac from the current instance and build accordingly.

            Are specific PNG compression types incompatible with macOS Cocoa apps?
            Asked 2017-Jul-25 at 12:26

            We’ve had a recent issue with some asset images, where the Retina @2x version was being used on non-Retina devices. The Retina and non-Retina versions of the assets exist. We’ve tracked the problem down to compression, so we’re able avoid it for now, but if anyone has additional insights, I’d love to hear them.

            The icons on the left show how they’re rendering inside the running app. The Retina assets are being used on a non-Retina screen, so they’re being scaled down to 50%, which is causing some blurry edges.

            The icons on the right are the original assets.

            This is only happening to some assets. Most of the app is okay. We’ve been using ImageOptim to compress the PNGs used in the app. ImageOptim is using a variety of compression combinations for the assets. These are the common best results:

            • PNGOUT
            • PNGOUT+AdvPNG
            • PNGOUT+Zopfli
            • AdvPNG+Zopfli

            The assets that have problems all seem to be using PNGOUT+Zopfli, but not all assets with PNGOUT+Zopfli are bad. I am not 100% confident with this diagnosis though.

            Given that the issue isn’t always easy to spot, and given I don’t know exactly what’s wrong, we’ve unfortunately decided to not compress our new PNGs used in Mac apps. This is a shame, because the space savings are good.

            We’ve tried a few different Xcode project settings, including turning Combine High Resolution Artwork on and off.

            I’d like some answers, but I am also posting here so there’s some information that may help others with this issue, even if I only have a partial solution.

            For this to work, you do also need to have:

            • Python 2.7 or 3.1 installed
            • The latest version of npm (4.5.0 works). Run: npm i npm -g to update.
            • And node-gyp installed globally. Run npm install -g node-gyp

            How to choose a custom node version for Azure WebJobs
            Asked 2017-Mar-07 at 01:54

            I'm working on a website that deploys its custom version of node (x64) that we upload and configure via iisnode.yml. We have a dependency in a binary package (zopfli) that we build locally and deploy as well. So far so good. The problem is with one of the webjobs we have. It seems like it is always using the x86 version of the node version set in WEBSITE_NODE_DEFAULT_VERSION no matter the value of issnode.yml or the platform I select via the portal.

            So my question is:

            How can I tell my webjobs to use the same version I specify in iisnode.yml (bin\node.exe)?
