Add two images pixel-wise.

arithmeticBindings.add(image1, image2, output);

Subtract one image from another.

arithmeticBindings.subtract(image1, image2, output);

Multiply two images pixel-wise.

arithmeticBindings.multiply(image1, image2, output);

Divide one image by another.

arithmeticBindings.divide(image1, image2, output);

Clamp pixel values to range 0-1.

// Pipeline API (clamps to 0-1 range)
pipeline.clamp()

Calculate image statistics (min, max, mean, etc.).

final statsImage = arithmeticBindings.stats(input);
// Returns a 1-band image with statistics

Apply mathematical function to image.

arithmeticBindings.math(input, output, VipsOperationMath.sin);

Operations: sin, cos, tan, asin, acos, atan, log, log10, exp, exp10
