Struct ChipTransform 

pub struct ChipTransform {
    pub a: i32,
    pub b: i32,
    pub c: i32,
    pub d: i32,
    pub tx: i32,
    pub ty: i32,
}

Affine transformation for chip coordinate mapping.

Formula: global_x = a * local_x + b * local_y + tx global_y = c * local_x + d * local_y + ty

Fields

a: i32

Local X coefficient for affine transform.

b: i32

Local Y coefficient for affine transform in X output.

c: i32

Local X coefficient for affine transform in Y output.

d: i32

Local Y coefficient for affine transform.

tx: i32

Translation in X direction.

ty: i32

Translation in Y direction.

Implementations

impl ChipTransform

pub fn identity() -> Self

Create an identity transform.

pub fn apply(&self, x: u16, y: u16) -> (u16, u16)

Apply transform to local coordinates.

Note

This method assumes the transform has been validated via validate_bounds(). Using an unvalidated transform may cause incorrect results due to integer overflow.

pub fn validate_bounds( &self, chip_size_x: u16, chip_size_y: u16, ) -> Result<(), String>

Validate that this transform produces valid u16 coordinates for all inputs in the range [0, chip_size_x) x [0, chip_size_y).

This checks all 4 corners of the input space, which is sufficient because affine transforms are linear (extremes occur at corners).

Errors

Returns an error if the transform maps any corner outside the valid output range.

Trait Implementations

impl Clone for ChipTransform

fn clone(&self) -> ChipTransform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChipTransform

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ChipTransform

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for ChipTransform

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
