class simvx.core.nodes_2d.ninepatch.NinePatchRect(**kwargs: Any)

Bases: simvx.core.nodes_2d.node2d.Node2D

9-slice scalable bordered texture for UI panels, speech bubbles, and HUD elements.

Divides a source texture into 9 regions using margin values. Corners stay fixed-size, edges stretch along one axis, and the centre fills the remainder.

get_rect() → simvx.core.nodes_2d.ninepatch.PatchRect

Bounding rectangle at global position with current display size.

get_nine_patch_rects() → list[tuple[simvx.core.nodes_2d.ninepatch.PatchRect, simvx.core.nodes_2d.ninepatch.PatchRect]]

Compute (source_uv_rect, dest_position_rect) pairs for the 9 patches.

Returns up to 9 pairs (8 if draw_center is False). Patches with zero width or height are omitted.

draw(renderer) → None

Draw the 9-patch texture via renderer.draw_texture_region().
