A Dart library providing the ability to load, save and manipulate images in a variety of different file formats.
The library has no reliance on dart:io, so it can be used for both server and
web applications.
Supported Image Formats:
Read/Write:
- PNG / Animated APNG
- JPEG
- Targa
- GIF / Animated GIF
- PVR(PVRTC)
Read Only:
- WebP / Animated WebP
- TIFF
- Photoshop PSD
- OpenEXR
Load an image, resize it, and save it as a png:
import 'dart:io';
import 'package:image/image.dart';
void main() {
// Read an image from file (webp in this case).
// decodeImage will identify the format of the image and use the appropriate
// decoder.
Image image = decodeImage(File('test.webp').readAsBytesSync());
// Resize the image to a 120x? thumbnail (maintaining the aspect ratio).
Image thumbnail = copyResize(image, width: 120);
// Save the thumbnail as a PNG.
File('thumbnail.png')..writeAsBytesSync(encodePng(thumbnail));
}
