FirebaseVisionImage.fromBytes constructor
FirebaseVisionImage.fromBytes(
- Uint8List bytes,
- FirebaseVisionImageMetadata metadata
Construct a FirebaseVisionImage from a list of bytes.
On Android, expects android.graphics.ImageFormat.NV21
format. Note:
Concatenating the planes of android.graphics.ImageFormat.YUV_420_888
into a single plane, converts it to android.graphics.ImageFormat.NV21
.
On iOS, expects kCVPixelFormatType_32BGRA
format. However, this should
work with most formats from kCVPixelFormatType_*
.
Implementation
factory FirebaseVisionImage.fromBytes(
Uint8List bytes,
FirebaseVisionImageMetadata metadata,
) {
return FirebaseVisionImage._(
type: _ImageType.bytes,
bytes: bytes,
metadata: metadata,
);
}
