Once you have dependencies installed, compile with cargo build -release -features=video or cargo build -release -features=video-static. If you're cross-compiling, try uncommenting section at the end of Cargo.toml, which includes some experimental fixes for ffmpeg.

Especially on macOS and Windows it takes expert knowledge to just get them installed without wasting several hours on endless stupid installation and compilation errors, which I can't help with. Please note that installation of these dependencies may be quite difficult.

#IMAGEOPTIM. INSTALL#

Details depend on the platform and version, but you usually need to install packages such as libavformat-dev, libavfilter-dev, libavdevice-dev, libclang-dev, clang. You must have ffmpeg and libclang installed, both with their C headers installed in default system include paths. The tool optionally supports decoding video directly, but unfortunately it relies on ffmpeg 4.x, which may be very hard to get working, so it's not enabled by default. Let me know if you'd like to use it in a product incompatible with this license. I can offer alternative licensing options, including commercial licenses. The cbuild command can be omitted, since cinstall will trigger a build if it hasn't been done already. To build the library, run:Ĭargo cinstall -prefix=/usr -release -destdir=pkgroot

In the cloned directory, run: cargo build -release.

#IMAGEOPTIM. UPDATE#

if you don't run rustup update regularly. You may get compile errors, warnings about 'unstable edition', etc. This project only supports up-to-date versions of Rust.

Install Rust via rustup or run rustup update.

The command line tool will display estimated total file size during compression, but keep in mind that the estimate is very imprecise. If you need to make a GIF that fits a predefined file size, you have to experiment with different sizes and quality settings.

-motion-quality=60 lower values cause smearing or banding in frames with motion, but reduce file sizes.

-lossy-quality=60 lower values make animations noisier/grainy, but reduce file sizes.

Add -quality=80 (or a lower number) to lower overall quality.

Use -width and -height to make the animation smaller.

GIF just isn't that good at compressing, no matter how much you compromise. Tips for smaller GIF filesĮxpect to lose a lot of quality for little gain. If the input was ever encoded using a lossy video codec it's recommended to at least halve size of the frames to hide compression artefacts and counter chroma subsampling that was done by the video codec. This has.You can also resize frames (with -W option). Sometimes I try out some workflow optimization and it doesn’t stick. Most importantly, I’ve actually stuck with it. It’s a simple thing that has helped me a ton and might help you. This is a pretty simple and obvious thing that I could have done years ago. See this image? The one right above? It was automatically optimized with Hazel and ImageOptim. We watch the Desktop folder and if the kind of file is an Image, open it in ImageOptim. For example, you can watch your Downloads folder, and if the type of file is a Movie, you can automatically move it to the Movies folder. It’s basically a watch task for macOS, with a UI to set up all the stuff you want it to do. I didn’t go down that road, though, because… Enter HazelĪ number of recommendations from folks turned me onto Hazel. Like putting the command into `~/.bash_profile` or something. I bet there is some trickery to avoid that. This wouldn’t be much different.Įxcept… that we’d need to gulp watch (or whatever) from the command line every time we restarted. A lot of us probably already do this with the web projects we work on. Then if an image file appears there, run an image optimization task. One way to approach this would be to set up a Grunt/Gulp/Webpack/Whatever watch task to watch the Desktop. What if we didn’t need to optimize images because any image that was on the Desktop was automatically optimized? That’s what we’re shooting for here. Making any image on the Desktop automatically optimized The Desktop is a convenient place, for me, for all that to happen. Perhaps it’s a screenshot that needs to get resized, then optimized, then uploaded somewhere, then deleted. Images are one of the most common things that end up there. I do whatever I’m doing with them, then move them away. Things I’m actively using go on the Desktop. Monotonous repetitive tasks are fertile ground for computerization, so let’s computerize it. If we’re taught one thing about images and the web, it’s that they should be optimized.įor me, that means dragging every single image onto ImageOptim before using it. I work with images as part of blog posts, images as part of sites I’m working on, images headed to social media… images everywhere. I’m forever trying to make my local image workflow easier.
