@brief Enumeration indicating the method used in the masking of two objects - the target and the source.

@ingroup ThorVGCapi_Paint

Variants

TVG_MASK_METHOD_NONE = 0

< No Masking is applied.

TVG_MASK_METHOD_ALPHA = 1

< Alpha Masking using the masking target’s pixels as an alpha value.

TVG_MASK_METHOD_INVERSE_ALPHA = 2

< Alpha Masking using the complement to the masking target’s pixels as an alpha value.

TVG_MASK_METHOD_LUMA = 3

< Alpha Masking using the grayscale (0.2126R + 0.7152G + 0.0722*B) of the masking target’s pixels. @since 0.9

TVG_MASK_METHOD_INVERSE_LUMA = 4

< Alpha Masking using the grayscale (0.2126R + 0.7152G + 0.0722*B) of the complement to the masking target’s pixels. @since 0.11

TVG_MASK_METHOD_ADD = 5

< Combines the target and source objects pixels using target alpha. (T * TA) + (S * (255 - TA)) @since 1.0

TVG_MASK_METHOD_SUBTRACT = 6

< Subtracts the source color from the target color while considering their respective target alpha. (T * TA) - (S * (255 - TA)) @since 1.0

TVG_MASK_METHOD_INTERSECT = 7

< Computes the result by taking the minimum value between the target alpha and the source alpha and multiplies it with the target color. (T * min(TA, SA)) @since 1.0

TVG_MASK_METHOD_DIFFERENCE = 8

< Calculates the absolute difference between the target color and the source color multiplied by the complement of the target alpha. abs(T - S * (255 - TA)) @since 1.0

TVG_MASK_METHOD_LIGHTEN = 9

< Where multiple masks intersect, the highest transparency value is used. @since 1.0

TVG_MASK_METHOD_DARKEN = 10

< Where multiple masks intersect, the lowest transparency value is used. @since 1.0

Trait Implementations

impl Clone for Tvg_Mask_Method

fn clone(&self) -> Tvg_Mask_Method

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Tvg_Mask_Method

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Tvg_Mask_Method

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Tvg_Mask_Method

fn eq(&self, other: &Tvg_Mask_Method) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
