Overview ¶
Package canvasconv 为 canvas 绘制后端和字体引擎共享 OFD 画笔与渐变适配。 几何类型直接共享，仅在绘制入口补齐空路径、端点和连接器的默认值。

Functions ¶
func FromCanvasCapper ¶
FromCanvasCapper 保留线帽实现，nil沿用平头默认值。
func FromCanvasGradient ¶
FromCanvasGradient 保留原生轴向/径向渐变的几何类型，使文字轮廓裁剪后 仍可序列化为PDF/SVG渐变；其他采样器使用接口包装。
func FromCanvasJoiner ¶
FromCanvasJoiner 保留连接器实现，nil沿用斜接默认值。
func FromCanvasPaint ¶
FromCanvasPaint 把 canvas.Paint 转为 geom.Paint。
func ToCanvasCapper ¶
ToCanvasCapper 保留线帽实现，nil沿用平头默认值。
func ToCanvasGradient ¶
ToCanvasGradient 把 geom.Gradient 包装为 canvas.Gradient。原生的 *geom.LinearGradient/*geom.RadialGradient 会还原为 canvas 原生线性/径向 渐变，以保留 PDF/SVG 的矢量渐变输出；其余自定义采样渐变包装为 canvas.Gradient（canvas 无法矢量序列化时按采样栅格化）。默认 LinearColorSpace（canvas 不做 gamma 往返）下采样结果与 canvas 原生渐变一致。
func ToCanvasJoiner ¶
ToCanvasJoiner 保留连接器实现，nil沿用斜接默认值。
func ToCanvasPaint ¶
ToCanvasPaint 把 geom.Paint 转为 canvas.Paint。
