Crate yog_graphics 

yog-graphics — the graphics primitives every Yog crate shares, so a color, a rectangle or a picture is one type everywhere: Color, Vec2/Vec3/Mat4, Rect, vector Seg paths, RGBA Images, drawings (Op: paths filled and stroked, images) and a Canvas that paints them to pixels.

Modules

color

Colors: 0xAARRGGBB, straight alpha — what every Yog format and API passes.

draw

Drawings: what to paint, in order — paths filled or stroked, images — in a drawing’s own units (y up). Glyphs, icons and shapes are drawings; a Canvas paints them.

image

RGBA images.

mask

One-color pictures, a bit a pixel: a pixel font’s glyph is one — a thirty-second of the same picture as RGBA.

math

Vectors and 4×4 matrices (column-major, as JOML and the hosts’ PoseStack keep them).

path

Vector paths: contours of lines and curves, as fonts, SVG and drawn shapes describe them.

raster

A canvas to draw on in pixels (y down): shapes filled with signed-area coverage (anti-aliased, non-zero winding), strokes as the union of their segments with round joins and caps, images sampled into place.

rect

Axis-aligned rectangles.

Structs

Canvas

Pixels being drawn, premultiplied, in floats.

Color

A color, 0xAARRGGBB.

Fill

Image

Pixels, RGBA8 row by row from the top, straight alpha.

ImageOp

image in box rect (rect.x, rect.y its bottom-left corner).

Mask

width × height pixels, a bit each: rows top to bottom, a row’s pixels from its first byte’s highest bit on, each row whole bytes.

MaskOp

mask in box rect (rect.x, rect.y its bottom-left corner), its set pixels color (none: the current color — a text’s).

Mat4

A 4×4 matrix, column-major: m[col * 4 + row].

PlacedImage

An image and where it goes: its top-left corner x, y pixels (y down) from the origin it was drawn for — a glyph’s from its pen position on the baseline, say.

Rect

A rectangle: its corner x, y (the one with the smallest coordinates) and its size.

Stroke

Vec2

A point or a direction in a plane.

Vec3

Enums

Op

One step of a drawing.

Seg

A path segment.

Constants

BYTES_PER_PIXEL

Bytes per pixel: red, green, blue, alpha.

Functions

rad

Degrees to radians, for the formats (which are in degrees).

Type Aliases

Rgba8

One RGBA8 pixel.
