Module layer_transform 

Transform math of a graphics layer, re-exported from cranpose_ui_graphics.

Functions

apply_layer_affine_to_point

Point counterpart of apply_layer_affine_to_rect: scale about the layer pivot, then translate. Rotation/perspective are deliberately excluded — the affine space is the one SDF shapes are evaluated in, with rotation carried by the deformed quad instead.

apply_layer_affine_to_rect

Scales and translates a rectangle around the layer’s transform origin.

apply_layer_to_quad

Transforms a rectangle’s four corners through scale, rotation and perspective.

apply_layer_to_rect

Returns the axis-aligned bounds after the complete layer transform.

layer_scene

The scene a layer’s graphics layer shows, or None for a layer that shows none.

layer_surface

The mesh a layer’s graphics layer draws its content on, or None for a layer drawn flat.

layer_transform3d

The move a layer’s graphics layer gives the 3D frames beneath it, or None for none.

layer_transform_to_parent

Combines a graphics layer with the node’s placement in its parent.

layer_transform_to_window

Extends an ancestor mapping from untransformed layout coordinates to window coordinates with this node’s graphics layer. origin and bounds describe the node before any ancestor transforms; bounds is relative to origin.

layer_uniform_scale

Returns the smaller of the layer’s horizontal and vertical scales.
