com.nsdev.lettergenerator.model.block.CanvasBlock
Record Components:
widthMm - positive finite canvas width, no larger than available width
heightMm - positive finite canvas height
elements - ordered owned element list with unique identifiers
style - nullable inherited typography and outer spacing/pagination overrides
All Implemented Interfaces:
Block
public record CanvasBlock(double widthMm, double heightMm, List<PositionedContent> elements, Style style) extends Record implements Block
A fixed-size flow unit containing arbitrary bounded elements in stable paint order. It consumes its declared height and moves to a following page as one unit when necessary. Native content overflow fails generation instead of clipping or shrinking the canvas.
