AniEnc
Cross-platform tool for converting and resizing animations, powered by Magick.NET and CliFx.
Implemented features
- Conversion (to any format supported by ImageMagick)
- Resizing (px / % / auto, various interpolation algorithms)
- GIF optimization (all options available in Magick.NET)
- Coalesce (by default when resizing)
- Image enhancement
System requirements
- Any platform supported by both .NET and Magick.NET
- On x86/x64, Windows/Linux/macOS should all work
- ARM is not fully supported
- .NET 6.0 Runtime
- (optional) FFmpeg installed to
$PATH- This is required for some formats such as WebM, APNG
- On Windows, I use media-autobuild_suite to build FFmpeg
How to use
Usage:
dotnet anienc.dll <input> [<options>]
To convert a GIF to WebM:
dotnet anienc.dll test.gif -f webm
To resize a GIF:
dotnet anienc.dll test.gif -r 640 480 -f gif
To optimize a GIF:
dotnet anienc.dll test.gif -p 2 -f gif
(for single-file builds, you may replace dotnet anienc.dll with anienc in the above examples)
Unique features
AniEnc has support for converting Ugoira. These are animations from Pixiv, downloaded with a tool such as PixivUtil2. Two files are required, .zip and .zip.js - specify one of them as the input and the tool will find the other one automatically.
Future plans
- Better resizing options (fit)
- Noise reduction algorithms
- Extra support for JPEG XL animations (one of the initial goals of this project, as soon as ImageMagick has support)
- Simple timing adjustments
- Cutting
- Cropping
- Converting to/from individual frames
