Expand description

Layout manager for intelligent positioning of elements on a page

This manager handles automatic positioning of tables, images, and other elements using different coordinate systems while preventing overlaps and managing page flow.

Fields§

§coordinate_system: CoordinateSystem

Coordinate system being used

§current_y: f64

Current Y position for next element

§page_width: f64

Page dimensions

§page_height: f64§margins: Margins

Page margins

§element_spacing: f64

Spacing between elements

Implementations§

Source §

impl LayoutManager

Source

pub fn new(page: &Page, coordinate_system: CoordinateSystem) -> Self

Create a new layout manager for the given page

Source

pub fn with_element_spacing(self, spacing: f64) -> Self

Set custom spacing between elements

Source

pub fn will_fit(&self, element_height: f64) -> bool

Check if an element of given height will fit on the current page

Source

pub fn remaining_space(&self) -> f64

Get the current available space remaining on the page

Source

pub fn add_element(&mut self, element_height: f64) -> Option<f64>

Reserve space for an element and return its Y position

Returns None if the element doesn’t fit on the current page. If it fits, returns the Y coordinate where the element should be placed and updates the internal current_y for the next element.

Source

pub fn new_page(&mut self)

Reset the layout manager for a new page

Source

pub fn center_x(&self, element_width: f64) -> f64

Get the X position for centering an element of given width

Source

pub fn left_x(&self) -> f64

Get the left margin X position

Source

pub fn right_x(&self, element_width: f64) -> f64

Get the right margin X position minus element width
