Function boolean_const 

pub fn boolean_const(
    inp: &VipsImage,
    boolean: OperationBoolean,
    c: &mut [f64],
) -> Result<VipsImage>

VipsBooleanConst (boolean_const), boolean operations against a constant inp: &VipsImage -> Input image boolean: OperationBoolean -> Boolean to perform And -> VIPS_OPERATION_BOOLEAN_AND = 0 [DEFAULT] Or -> VIPS_OPERATION_BOOLEAN_OR = 1 Eor -> VIPS_OPERATION_BOOLEAN_EOR = 2 Lshift -> VIPS_OPERATION_BOOLEAN_LSHIFT = 3 Rshift -> VIPS_OPERATION_BOOLEAN_RSHIFT = 4 Last -> VIPS_OPERATION_BOOLEAN_LAST = 5 c: &mut [f64] -> Array of constants returns VipsImage - Output image
