LunaSVG is an SVG rendering library in C++, designed to be lightweight and portable, offering efficient rendering and manipulation of Scalable Vector Graphics (SVG) files.
#include <lunasvg.h>
using namespace lunasvg;
int main()
{
auto document = Document::loadFromFile("tiger.svg");
if(document == nullptr)
return -1;
auto bitmap = document->renderToBitmap();
if(bitmap.isNull())
return -1;
bitmap.writeToPng("tiger.png");
return 0;
}
LunaSVG supports nearly all graphical features outlined in the SVG 1.1 and SVG 1.2 Tiny specifications. The primary exceptions are animation, filters, and scripts. As LunaSVG is designed for static rendering, animation is unlikely to be supported in the future. However, support for filters may be added. It currently handles a wide variety of elements, including:
<a> <circle> <clipPath> <defs> <ellipse> <g> <image> <line> <linearGradient> <marker> <mask> <path> <pattern> <polygon> <polyline> <radialGradient> <rect> <stop> <style> <svg> <symbol> <text> <tspan> <use>
