Functions

computeAdaptiveThreshold(Uint8List pixels, int width, int height) → int

Computes an adaptive threshold for converting a grayscale image to black and white.

computeKernelSize(int width, int height, double scaleFactor) → int

Computes the appropriate kernel size for dilation based on image dimensions.

createImageFromPixels(Uint8List pixels, int width, int height) → Future<Image>

Creates a new Image from a Uint8List of pixel data.

imageToBlackOnWhite(Image inputImage, {double contrast = 0}) → Future<Image>

Converts a color image to a binary (black and white) image.

imageToUint8List(Image image) → Future<Uint8List>

Converts a Image to a Uint8List representation.
