tiny_skia::Transform Class Reference

2D affine transformation: [sx kx tx; ky sy ty; 0 0 1]. More...

#include <tiny_skia/Transform.h>

Public Member Functions
std::optional< Transform >	invert () const
	Returns the inverse, or nullopt if singular.
Transform	preConcat (const Transform &other) const
	Returns this * other (other applied first).
Transform	postConcat (const Transform &other) const
	Returns other * this (this applied first).
void	mapPoints (std::span< Point > points) const
	Transforms an array of points in-place.

Static Public Member Functions
static constexpr Transform	fromRow (float sx, float ky, float kx, float sy, float tx, float ty)
	Creates from all 6 matrix entries (row-major: sx, ky, kx, sy, tx, ty).

Public Attributes
float	sx = 1.0f
	Horizontal scale.
float	kx = 0.0f
	Horizontal skew.
float	ky = 0.0f
	Vertical skew.
float	sy = 1.0f
	Vertical scale.
float	tx = 0.0f
	Horizontal translation.
float	ty = 0.0f
	Vertical translation.

Detailed Description

Supports translate, scale, skew. Use fromTranslate/fromScale for common cases, fromRow for arbitrary matrices. Compose with preConcat/postConcat.
