# findkey_ts

[🇷🇺 Версия на русском](README_ru.md)

Program to compute Affine/Helmert 2D transformation parameters.

Ported from C to TS by li0ard

**ATTENTION: This program is only compatible with [Bun](https://bun.sh)**

## CLI

### Usage

```

findkey_ts --f1  --f2 

```

### Input files

For the program to work, 2 files are needed: a file with coordinates in the original coordinate system and a file with coordinates in the desired coordinate system (6-7 pairs of coordinates are needed for the best result)

Coordinate pairs are written in the `Y X` format

## API

```ts

/** Represents the formatted transformation parameters */

export interface formattedH {

    A0: number,

    A1: number,

    A2: number,

    B0: number,

    B1: number,

    B2: number,

}

/** Represents the transformation parameters with scale (mu), angle (theta), and residuals */

export interface Keys {

    h: formattedH,

    mu: number,

    theta: number,

    residuals: number[][]

}

/**

 * Find parameters

 * @param fp0 Array with coordinates in original CS in the format "Y X"

 * @param fp1 Array with coordinates in desired CS in the format "Y X"

 * @returns 

 */

export const findKey = (fp0: string[], fp1: string[]): Keys => {}

/**

 * Reverse parameters

 * @param h Property `h` of `findKey` function result 

 * @returns 

 */

export const reverseH = (h: formattedH): formattedH => {}

```
