Detailed Description

String literal operators for creating Color instances.

This namespace provides the _c suffix operator for creating colors from string literals at compile-time (when possible).

Usage

using namespace novasvg::color_literals;
 
Color c1 = "red"_c;           // From color name
Color c2 = "#FF0000"_c;      // From hex
Color c3 = "gray"_c | 50;    // Blend with transparent
Color c4 = "gray"_c | 50 | "black"_c;  // Chain blends

Note

Always include "using namespace novasvg::color_literals;" or use explicit qualification to use these literals.

novasvg::Color novasvg::color_literals::operator""_c ( const char *  str, std::size_t  len  )

inline

String literal operator for creating Color instances.

This operator allows creating colors using the _c suffix on string literals. It automatically detects whether the string is a hex color code or a color name.

Parameters

str	String literal (must include quotes).
len	Length of the string literal.

Returns

Color instance parsed from the string.

Exceptions

std::invalid_argument

If the format is invalid or the color name is not recognized.

Example

using namespace novasvg::color_literals;
 
Color c1 = "red"_c;         // Color::red()
Color c2 = "#FF0000"_c;     // Color::fromHash("#FF0000")
Color c3 = "skyblue"_c;     // Color::fromName("skyblue")
Color c4 = "gray"_c | 50;   // Blend with 50% transparent

Note

The string must be a valid string literal. For runtime strings, use Color::fromString() instead.
