# What does the class affinetransform do in Java?

## What does the class affinetransform do in Java?

The AffineTransform class represents a 2D affine transform that performs a linear mapping from 2D coordinates to other 2D coordinates that preserves the “straightness” and “parallelness” of lines. Affine transformations can be constructed using sequences of translations, scales, flips, rotations, and shears.

### How is an affine transformation represented in Java?

Affine transformations can be constructed using sequences of translations, scales, flips, rotations, and shears. Such a coordinate transformation can be represented by a 3 row by 3 column matrix with an implied last row of [ 0 0 1 ].

**What is the double precision argument in affinetransform?**

In some variations of the rotate methods in the AffineTransform class, a double-precision argument specifies the angle of rotation in radians.

**What does the flag bit mean in affinetransform?**

A translation moves the coordinates by a constant amount in x and y without changing the length or angle of vectors. This flag bit indicates that the transform defined by this object performs a uniform scale in addition to the conversions indicated by other flag bits.

## How to define a point in affine matrix?

A Point can be defined in two different ways: Calculate a point transformed with an affine matrix Extract an affine matrix from an object that contains a,b,c,d,e,f keys Any value could be a float or a string that contains a float Warning: This should be considered BETA until it is released a stable version of pegjs.

### How is a point defined in a transformation matrix?

A transformation Matrix is defined as a Plain Object with 6 keys: a, b, c, d, e and f. A Point can be defined in two different ways: Calculate a point transformed with an affine matrix
