vitem¶
- class janim.items.vitem.VItem(*points: Vect, fill_alpha=0, **kwargs)¶
基类：
Points贝塞尔曲线拼接物件，具体说明请参考
Cmpt_VPoints的文档- points¶
- radius¶
- stroke¶
- fill¶
- glow¶
- color¶
- renderer_cls¶
VItemRenderer的别名
- init_connect() None¶
- apply_style(stroke_radius: float | Iterable[float] | None = None, stroke_color: JAnimColor | ColorArray | None = None, stroke_alpha: Alpha | AlphaArray | None = None, stroke_background: bool | None = None, fill_color: JAnimColor | ColorArray | None = None, fill_alpha: Alpha | AlphaArray | None = None, color: JAnimColor | ColorArray | None = None, alpha: Alpha | AlphaArray | None = None, glow_color: JAnimColor | None = None, glow_alpha: Alpha | None = None, glow_size: float | None = None, **kwargs) Self¶
设置物件自身的样式，不影响子物件
另见：
set()
- set_stroke_background(flag: bool = True, *, root_only: bool = False) Self¶
调整描边与填充的绘制顺序
flag=True会使得描边被填充遮盖，flag=False则会使得填充被描边遮盖
- add_tip(alpha: float = 1.0, reverse: bool = False, angle: float | None = None, colorize: bool = True, fill_color: JAnimColor | None = None, stroke_color: JAnimColor | None = None, color: JAnimColor | None = None, d_alpha: float = 1e-06, **tip_kwargs)¶
在
alpha处创建一个箭头默认情况下，箭头与路径方向同向；若传入
reverse=True则反向若传入
colorize=True（默认），则会使箭头的颜色与路径的颜色相同其余参数请参考
ArrowTip
- classmethod align_for_interpolate(item1: VItem, item2: VItem) AlignedData[Self]¶
进行数据对齐，以便插值
- class janim.items.vitem.DashedVItem(vitem: VItem, num_dashes: int = 15, *, dashed_ratio: float = 0.5, dash_offset: float = 0, stroke_color: JAnimColor | ColorArray | None = None, stroke_alpha: Alpha | AlphaArray | None = None, stroke_radius: float | Iterable[float] | None = None, equal_lengths: Literal['equal', 'approx', 'none'] = 'approx', **kwargs)¶
-
创建传入的
vitem的虚线化版本num_dashes: 虚线段的数量dashed_ratio: 虚线段的占比，剩下的占比即为空白段dash_offset: 将虚线段的起始点沿着路径偏移的比率，例如1表示偏移一个虚线段的长度equal_lengths: 虚线段的长度是否相等，取值为'equal'、'approx'或'none''equal': 虚线段长度几乎相等'approx': 虚线段长度近似相等'none': 虚线段将按照曲线的参数 t 均匀分布，一般来说长度不相等
