ggfx

GGFX is a generic software graphics library that can operate on arrays of pixels, regardless of what type the pixels are. As such, it does not deal with alpha values or blending.

Types

type Image

type Image[T any] struct {
	// Pix is the actual pixel array of the image.
	Pix []T

	// Stride represents the distance in slice elements between two pixels
	// that are vertically adjacent.
	Stride int

	// Width specifies how many slice elements make up a single pixel.
	Width int

	// Rect specifies a rectangle that all drawing operations will be
	// clipped to. It must not reside outside of Data. It is measured in
	// pixels and not slice elements.
	Rect image.Rectangle
