simple_native_image_compress 1.0.1

A simple native image compression library for Flutter that supports Windows and Linux as well

simple_native_image_compress

A simple native image compression library for Flutter written in rust using flutter_rust_bridge and image

Why?

1. For some reason, image compression in Dart is slow. Even with isolate.
2. There is no native libraries that supports WINDOWS & LINUX when it comes to image compression.

What does it do?

• If path for an image file is given, it will resize and return Jpeg/WebP image as Uint8List.

Prerequisite

1. Rust
2. Android NDK for Android

Example

Call Library as a Singleton

final _compress = SimpleNativeImageCompress();

"contain" will make the image fit into the given max width/height.

try{
  final bytes = await _compress.contain(
    filePath: yourFilePath,
    compressFormat: CompressFormat.Jpeg,
    quality: 90,
    maxWidth: 512,
    maxHeight: 512,
  );
} catch (e) {
  print(e);
}

"fitWidth" will make the image fit into the given max width.

try{
  final bytes = await _compress.fitWidth(
    filePath: yourFilePath,
    compressFormat: CompressFormat.WebP,
    maxWidth: 512,
  );
} catch (e) {
  print(e);
}

"fitHeight" will make the image fit into the given max height.

try{
  final bytes = await _compress.fitHeight(
    filePath: yourFilePath,
    compressFormat: CompressFormat.WebP,
    maxHeight: 512,
  );
} catch (e) {
  print(e);
}

Default values

• Default value for width and/or height is 1024 px
• Default value for Jpeg quality is 80 (For webP Quality does nothing)

Supported Formats

• Jpeg
• WebP

Miscellaneous

• May run slow on debug mode, but it is fine with release mode

TODO

Since I work on this on my spare time, I don't know when the TODO list will be completed.
