摘要
MapFrame 对象是一个布局元素,用于显示地图的内容。 它还用于访问布局大小、在布局上的位置、基本导航方法以及导出选项。
说明
MapFrame 是一个布局元素,用于显示添加到地图的地理信息。 Layout 对象上的 listElements 方法用于返回布局元素的 Python 列表。 要仅返回仅地图框列表,将 MAPFRAME_ELEMENT 常量用于 element_type 参数。 还可以使用 wildcard 对基于元素 name 的搜索进行进一步优化。
Layout 类上的 createMapFrame 方法还将返回地图框引用。
在引用 MapFrame 后,可通过属性和方法执行不同的操作。 首先,可使用基本属性控制地图框在布局上的大小、定位和可见性。 其次,可使用 panToExtent、zoomToAllLayers 和 zoomToBookmark 等诸多导航方法修改在地图框中显示的感兴趣区。 再次,可使用 map 属性更改或访问相关地图。 可在此直接管理底图中的图层、表和底图,以及访问地图的照相机信息,以进一步修改感兴趣区。 可切换尺寸相同或不同的地图。 最后,可使用各种导出方法将地图框导出为不同的导出格式。
属性

jpeg_color_mode | This value specifies the number of bits used to describe color.
(默认值为 24-BIT_TRUE_COLOR) | String |
jpeg_quality | This value (0–100) controls the amount of compression applied to the output image. For JPEG, image quality is adversely affected the more compression is applied. A higher quality (highest = 100) setting will produce sharper images and larger file sizes. A lower quality setting will produce more image artifacts and smaller files. (默认值为 80) | Integer |
embed_color_profile | If set to True, color profile information is embedded in the image's metadata. (默认值为 True) | Boolean |
JPEG 文件属于经过压缩的图像文件。 它支持 24 位颜色并且是 Web 上流行的使用格式,因为 JPEG 文件大小通常要比许多其他图像格式小很多。 但是,JPEG 压缩算法会有损质量,多数地图图像中都不推荐使用,因为线绘图以及文本或图标图形会因压缩产生的伪影而变得模糊。 因此,通常 PNG 格式才是地图图像的首选。 在生成 JPEG 文件的同时,还将生成一个坐标文件,可用作地理配准栅格数据。
exportToPDF (out_pdf, {resolution}, {image_quality}, {compress_vector_graphics}, {image_compression}, {embed_fonts}, {layers_attributes}, {georef_info}, {jpeg_compression_quality}, {output_as_image}, {embed_color_profile}, {convert_markers}, {simulate_overprint})

| String |
设置锚点位置非常有用,因为您可以控制元素在调整大小时的展开方式。 例如,地图框元素的默认锚点位置为 BOTTOM_LEFT_CORNER。 如果将锚点位置更改为 TOP_RIGHT_CORNER,则更改 elementHeight 将使元素向下扩展,而非向上扩展;更改 elementWidth 将使元素向左扩展。
setDefinition (definition_object)
参数 | 说明 | 数据类型 |
definition_object | A modified CIM definition object originally retrieved using getDefinition. | Object |
有关使用 CIM 和示例的详细信息,请参阅 Python CIM 访问。
