Functions

extractSvsImage(SvsFile svs, String type) → Future<Uint8List?>

Extracts the raw image bytes for an associated image (e.g. 'thumbnail', 'label', or 'macro') from an SVS file.

extractSvsImageAsImage(SvsFile svs, String type, {bool applyColorScheme = true, bool applyDisplayColor = true, int? displayColor}) → Future<Image?>

Extracts an associated image (e.g. 'thumbnail', 'label', or 'macro') from an SVS file and returns it as a decoded img.Image.

extractSvsImageAsJpeg(SvsFile svs, String type, {int quality = 90, bool applyColorScheme = true, bool applyDisplayColor = true, int? displayColor}) → Future<Uint8List?>

Extracts an associated image (e.g. 'thumbnail', 'label', or 'macro') from an SVS file and returns it as encoded JPEG bytes.

extractSvsTile(SvsFile svs, int layerIndex, int tileX, int tileY, {CancellationToken? cancelToken}) → Future<Uint8List?>

Extracts the raw bytes of a specific tile from a resolution layer in the SVS file.

extractSvsTileAsImage(SvsFile svs, int layerIndex, int tileX, int tileY, {bool applyColorScheme = true, bool applyDisplayColor = true, int? displayColor, CancellationToken? cancelToken}) → Future<Image?>

Extracts a specific tile from a resolution layer in the SVS file and returns it as a decoded img.Image.

openSvsFile(String path, {int maxConcurrency = 4}) → Future<SvsFile?>

Opens an SVS file at the specified path and reads its TIFF/BigTIFF header.

parseDisplayColor(dynamic value) → int?

Parses an integer display color from a dynamic value, string (decimal, hex with # or 0x), or int.

readFullSvsMetadata(SvsFile svs) → Future<SvsFullMetadata?>

Reads all metadata from the SVS file, including all pyramid levels and associated images.

readSvsMetadata(SvsFile svs) → Future<SvsMetadata?>

Reads basic metadata of the primary image from the SVS file.
