Crate colorimetry_plot 

Colorimetry Plot Library

This colormimetry library provides functionality for generating SVG-based color plots, with both low-level and higher level API, based on top of the Rust-SVG library. It includes generating basic 2D (x,y) charts composed of several layers, and more complex chromaticity diagrams with the spectral locus, and gamut fills. Here is an example of a XY Chromaticity Diagram for the DisplayP3 color space, using the CIE 2015 observer: Plots are built up in Layers using coordinate transformations between plot space and world coordinates.

Modules

• chart: Chart composition and rendering.
• layer: Layered rendering support for compositing multiple plot elements.
• rendable: Traits and types for objects that can be rendered to SVG.
• spectrum: Spectrum data visualization and color representation.
• style_attr: SVG styling attributes and utilities.
• svgdoc: SVG document creation and manipulation.
• view: Viewport and plot area management.

Core Features

• Layered Architecture: Build complex plots by compositing multiple layers
• Coordinate Transforms: Seamless conversion between plot and world coordinate systems
• SVG Generation: High-quality vector graphics output
• Configurable Styling: Flexible styling system for plot elements
• Precision Control: Configurable floating-point precision for clean output

Modules

chart

A two-dimensional chart implementation for plotting data in a Cartesian coordinate system.

layer

Layer module for SVG rendering

rendable

Rendable Trait Module

style_attr

Style attributes for SVG elements in the plotting library

svgdoc

SVG document representation and rendering.

view

View parameters for SVG rendering.

Macros

css

A StyleAttr struct with either the class, style, id or any combination of fields set. This macro allows for flexible creation of style attributes for SVG elements. It supports various combinations of class, style, and id attributes, making it easy to define the styling of SVG elements in a concise manner.

delegate_xy_chart_methods

Macro to delegate all XYChart methods to a field of a struct, to avoid using Deref and DerefMut Add methods here when adding new methods to XYChart Usage: delegate_xy_chart_methods!(MyStruct, chart_field);

Functions

last_id

Returns the last generated ID as a string. This can be useful for referencing the last created SVG element without generating a new ID.

new_id

Generates a new unique ID for SVG elements. The ID is prefixed with “id” and is incremented each time this function is called. This is useful for ensuring that each SVG element has a unique identifier.

round_to_default_precision

Rounds a floating-point value to the default precision. For example, round_to_default_precision(1.23456) returns 1.2. /// # Arguments

round_to_precision

Rounds a floating-point value to the specified precision. For example, round_to_precision(1.23456, 100.0) returns 1.23.
