FeatureCollection.style(color, pointSize, pointShape, width, fillColor, styleProperty, neighborhood, lineType) | Imagem |
Argumento | Tipo | Detalhes |
---|
isso: collection | FeatureCollection | A coleção a ser desenhada. |
color | String, padrão: "black" | Uma cor padrão (valor de cor CSS 3.0, por exemplo, "FF0000" ou "red") para usar no desenho dos recursos. Compatível com opacidade (por exemplo, "FF000088" para vermelho 50% transparente). |
pointSize | Número inteiro, padrão: 3 | O tamanho padrão em pixels dos marcadores de ponto. |
pointShape | String, padrão: "circle" | A forma padrão do marcador a ser desenhada em cada local. Uma destas opções: "circle", "square", "diamond", "cross", "plus", "pentagram", "hexagram", "triangle", "triangle_up", "triangle_down", "triangle_left", "triangle_right", "pentagon", "hexagon", "star5", "star6". Esse argumento também aceita estas abreviações de marcadores do Matlab: "o", "s", "d", "x", "+", "p", "h", "^", "v", "<", ">". |
width | Ponto flutuante, padrão: 2 | A largura de linha padrão para linhas e contornos de polígonos e formas de pontos. |
fillColor | String, padrão: null | A cor para preencher polígonos e formas de pontos. O padrão é "color" com opacidade de 0,66. |
styleProperty | String, padrão: null | Uma propriedade por recurso que deve conter um dicionário. Os valores no dicionário substituem os valores padrão desse recurso. |
neighborhood | Número inteiro, padrão: 5 | Se "styleProperty" for usado e algum recurso tiver um "pointSize" ou uma largura maior que os padrões, poderão ocorrer artefatos de segmentação. Especifica a vizinhança máxima (pointSize + largura) necessária para qualquer recurso. |
lineType | String, padrão: "solid" | O estilo de linha padrão para linhas e contornos de polígonos e formas de pontos. O padrão é "solid". Uma destas opções: sólido, pontilhado, tracejado. |
