Struct Transparency 

pub struct Transparency(/* private fields */);

Represents transparency in AutoCAD

Transparency is represented as an alpha value where:

• 0 = fully opaque (0% transparent)
• 255 = fully transparent (100% transparent)

Implementations

impl Transparency

pub const OPAQUE: Transparency

Fully opaque (0% transparent)

pub const TRANSPARENT: Transparency

Fully transparent (100% transparent)

pub const BY_LAYER: Transparency

Transparency ByLayer - uses the layer’s transparency

pub const T_10: Transparency

Common transparency values

pub const T_20: Transparency

pub const T_30: Transparency

pub const T_40: Transparency

pub const T_50: Transparency

pub const T_60: Transparency

pub const T_70: Transparency

pub const T_80: Transparency

pub const T_90: Transparency

pub const fn new(alpha: u8) -> Self

Create a new transparency from an alpha value (0-255)

pub fn from_percent(percent: f64) -> Self

Create transparency from a percentage (0.0 = opaque, 1.0 = transparent)

pub fn from_alpha_value(value: u32) -> Self

Create transparency from DWG alpha value (32-bit format)

The first byte represents the transparency type:

• 0 = BYLAYER
• 1 = BYBLOCK
• 3 = the transparency value in the last byte

pub const fn alpha(&self) -> u8

Get the raw alpha value (0-255)

pub fn as_percent(&self) -> f64

Get transparency as a percentage (0.0 = opaque, 1.0 = transparent)

pub const fn is_opaque(&self) -> bool

Check if fully opaque

pub const fn is_transparent(&self) -> bool

Check if fully transparent

pub fn to_alpha_value(&self) -> i32

Convert to DWG alpha value (32-bit format)

The first byte represents the transparency type:

• 0 = BYLAYER
• 1 = BYBLOCK
• 3 = the transparency value in the last byte

Trait Implementations

impl Clone for Transparency

fn clone(&self) -> Transparency

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Transparency

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

Formats the value using the given formatter.

impl Default for Transparency

fn default() -> Self

Returns the “default value” for a type.

impl Display for Transparency

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

Formats the value using the given formatter.

impl From<Transparency> for u8

fn from(transparency: Transparency) -> Self

Converts to this type from the input type.

impl From<u8> for Transparency

fn from(alpha: u8) -> Self

Converts to this type from the input type.

impl Ord for Transparency

fn cmp(&self, other: &Transparency) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Transparency

fn eq(&self, other: &Transparency) -> 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.

impl PartialOrd for Transparency

fn partial_cmp(&self, other: &Transparency) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
