说明：如图中的终点扎标是通过卡片生成的静态纹理。

时序图

卡片纹理管理器获取

卡片纹理销毁

关键参数

com.autonavi.gbl.card.model.StaticTextureParam

成员

含义

markerKey

决定纹理的关键参数，包含图片名和svg相关参数，该参数不同会重新生成纹理数据

anchorType

锚点类型

xRatio

x方向比率

yRatio

y方向比率

isGenMipmaps

是否生成mipmap

isRepeat

是否重复平铺方式

isPreMulAlpha

纹理是否预乘透明通道,1：预乘；0：未预乘


核心接口

boolean com.autonavi.gbl.map.layer.BaseLayer.addItem(LayerItem item)

int com.autonavi.gbl.map.layer.observer.IPrepareLayerStyle.getMarkerId(BaseLayer pLayer,

LayerItem pItem, String strMarkerId, String strMarkerInfo)

int com.autonavi.gbl.card.ITextureManager.addStaticTexture(StaticTextureParam texturePara)
