MapFrame

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 panToExtentzoomToAllLayerszoomToBookmark 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。

提示:

与尝试在应用程序外部导出 MapView 相比,在布局上导出 MapFrame 时生成的结果更一致。 MapView 的导出限制为地图视图仅使用在应用程序外部运行的 Python 脚本。 这是因为仅当打开应用程序及其视图窗格时才能获悉窗口和感兴趣区大小。MapFrame 导出将所有大小调整信息保留在元素中,因此在应用程序内部运行或在应用程序外部作为独立脚本运行的脚本将生成相同的导出结果。

属性

String
time
(只读)

如果启用时间的图层存在于地图框中,则返回 MapTime 对象。 如果地图框不包含启用时间的图层,则返回值 None

  • DEFLATEA lossless data compression.
  • JPEGJPEG compression.
  • LZWLempel-Ziv-Welch, a lossless data compression.
  • NONECompression is not applied.
  • PACK_BITSPack bits compression.

(默认值为 LZW)

String
geoTIFF_tags

If set to True, georeferencing tags are included in the structure of the TIFF export file. The tags contain pixel scale information and real-world coordinate information. These tags can be read by applications that support GeoTIFF format.

(默认值为 False)

Boolean
jpeg_compression_quality

This value (0–100) controls the amount of compression applied to the output image. With a 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

TIFF 文件最适合导入图像编辑应用程序,同时它也属于一种常用的 GIS 栅格数据格式。 但是却无法通过 Web 浏览器在本地查看这些文件。 TIFF 文件还支持在 GeoTIFF 标签中或在单独坐标文件中存储地理配准信息,以便用作栅格数据。

getDefinition (cim_version)
参数说明数据类型
cim_version

A string that represents the major version of the CIM that will be used.

  • V2The 2.x version of the CIM will be used.
  • V3The 3.x version of the CIM will be used.
String
返回值
数据类型说明
Object

返回 MapFrame 值的 CIM 定义。

有关使用 CIM 和示例的详细信息,请参阅 Python CIM 访问

getLayerExtent (layer, {selection_only}, {symbolized_extent})
参数说明数据类型
layer

引用 Layer 对象。

Layer
selection_only

如果为 True,将返回选定要素的范围;如果为 False,将返回所有要素的范围。

(默认值为 True)

Boolean
symbolized_extent

如果值为 True,将返回图层的符号化范围;否则将返回几何范围。符号化范围会将符号覆盖的区域考虑在内,因此该区域不会被数据框边界切掉。

(默认值为 True)

Boolean
返回值
数据类型说明
Extent

地理处理 Extent 对象。

getLayerExtent 方法将支持图层定义查询,因此如果查询了要素子集,则将只返回这些要素的范围。如果未选择要素,则将返回图层的范围。

panToExtent (extent)
参数说明数据类型
extent

地理处理 Extent 对象。

Extent

此方法尤为适合 MapFrame 比例未变而位置发生了变化的情况。无需设置范围以及每次都重置比例,panToExtent 保持比例不变,然后使当前地图框在新范围中居中。

setAnchor (anchor)
参数说明数据类型
anchor

A string that specifies the location of the anchor position.

  • BOTTOM_LEFT_CORNERThe anchor will be set at the bottom left corner position.
  • BOTTOM_MID_POINTThe anchor will be set at the bottom center position.
  • BOTTOM_RIGHT_CORNERThe anchor will be set at the bottom right corner position.
  • CENTER_POINTThe anchor will be set at the center position.
  • LEFT_MID_POINTThe anchor will be set at the left center position.
  • RIGHT_MID_POINTThe anchor will be set at the right center position.
  • TOP_LEFT_CORNERThe anchor will be set at the top left corner position.
  • TOP_MID_POINTThe anchor will be set at the top center position.
  • TOP_RIGHT_CORNERThe anchor will be set at the top right corner position.
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

zoomToAllLayers ({selection_only}, {symbolized_extent})
参数说明数据类型
selection_only

如果为 True,将根据选定要素设置范围;如果为 False,将为地图中的所有要素设置范围。

(默认值为 True)

Boolean
symbolized_extent

如果值为 True,将返回图层的符号化范围;否则将返回几何范围。符号化范围会将符号覆盖的区域考虑在内,因此该区域不会被地图框边界切掉。

(默认值为 True)

Boolean

如果对含有全局或本地场景的 MapFrame 使用了 zoomToAllLayers,则将生成平面视图。

zoomToBookmark (bookmark)
参数说明数据类型
bookmark

引用 Bookmark 对象。

Bookmark

如果对引用了 2D 地图MapFrame 使用了 3D 书签(反之亦然),则将生成平面试图。

代码示例

MapFrame 示例 1

以下脚本通过各种方式设置地图框范围并将每个结果导出为 PDF。 它首先使用要素选择设置范围。 接下来,它会缩放到单一图层范围并应用轻微缓冲区。 最后,它会执行相同的操作,但是会缩放到每个要素的范围。

import arcpy, os
aprx = arcpy.mp.ArcGISProject(r'C:\Projects\GreatLakes\GreatLakes.aprx')

m = aprx.listMaps('Map')[0]
lyr = m.listLayers('GreatLakes')[0]
lyt = aprx.listLayouts('Layout')[0]
mf = lyt.listElements('mapframe_element', 'Map Frame')[0]

#Zoom to ALL selected features and export to PDF
arcpy.SelectLayerByAttribute_management(lyr, 'NEW_SELECTION', "NAME = 'Lake Superior'")
mf.zoomToAllLayers(True)
mf.exportToPDF(r'C:\Projects\GreatLakes\Selection.pdf')
arcpy.SelectLayerByAttribute_management(lyr, 'CLEAR_SELECTION')

#Set the map frame extent to the extent of a layer and export to PDF
mf.camera.setExtent(mf.getLayerExtent(lyr, False, True))
mf.camera.scale = mf.camera.scale * 1.1 #add a slight buffer
mf.exportToPDF(r'C:\Projects\GreatLakes\GreatLakesExtent.pdf')

#Set the map frame extent based on eash feature in a layer and export to PDF
for row in arcpy.da.SearchCursor(lyr, ['SHAPE@', 'NAME']):
    mf.camera.setExtent(row[0].extent)
    mf.camera.scale = mf.camera.scale * 1.1 #add a slight buffer
    mf.exportToPDF(os.path.join(r'C:\Projects\GreatLakes', f'{row[1]}.pdf'))
MapFrame 示例 2

以下脚本会将 MXD 和 3DD 文档导入到空白工程中。 在引用适当的元素后,它会将每个 2D 插图地图更改为 3D 场景并将适当的书签应用于每个地图框。 最后,整个布局将导出为 PDF。

import arcpy
p = arcpy.mp.ArcGISProject(r'C:\Projects\Blank.aprx')

#Import documents into project
p.importDocument(r'C:\Projects\YosemiteNP\Documents\Yosemite.mxd')
p.importDocument(r'C:\Projects\YosemiteNP\Documents\Yosemite_3DViews.3dd')

#Reference maps
scene = p.listMaps('Globe layers')[0]

#Reference Layout and map frames
lyt = p.listLayouts()[0]
mainMF = lyt.listElements('MapFrame_Element', 'Yosemite National Park*')[0]
inset1MF = lyt.listElements('MapFrame_Element', 'Inset1*')[0]
inset2MF = lyt.listElements('MapFrame_Element', 'Inset2*')[0]

#Convert imported 2D insets into 3D views and zoom to bookmarks
mainMF.zoomToBookmark(mainMF.map.listBookmarks('Yosemite Valley')[0])

inset1MF.map = scene
inset1MF.zoomToBookmark(inset1MF.map.listBookmarks('Yosemite Yalley (looking East)')[0])

inset2MF.map = scene
inset2MF.zoomToBookmark(inset2MF.map.listBookmarks('Yosemite Valley (looking West)')[0])

#Export the resulting imported layout and changes to PDF
lyt.exportToPDF(r'C:\Projects\YosemiteNP\Example2_Export.pdf')
MapFrame 示例 3

以下脚本演示了如何使用几何和几何创建地图框。

p = arcpy.mp.ArcGISProject("CURRENT")

#Create a new map, layout
m = p.createMap('New Map', 'MAP')
lyt = p.createLayout(8.5, 11, 'INCH', 'New Layout')
lyt.openView()

#Create a new map frame using a polygon geometry
envCoordList = [[0.5, 5.75], [0.5, 10.5], [8, 10.5], [8, 5.75], [0.5, 5.75]]
envArray = arcpy.Array([arcpy.Point(*coords) for coords in envCoordList])
mf1 = lyt.createMapFrame(arcpy.Polygon(envArray), m, 'New MF - Poly')

#Create a new bookmark set to the map frame's default extent
bkmk = mf1.createBookmark('Default Extent', "The map's default extent")
bkmk.updateThumbnail()

#Create a new map frame using a point geometry
mf2 = lyt.createMapFrame(arcpy.Point(0.5,0.5), m, 'New MF - Point')
mf2.elementWidth = 7.5
mf2.elementHeight = 4.75
MapFrame 示例 4

以下脚本演示了如何使用 Python CIM 访问来修改布局中每个地图框的边界符号系统。

p = arcpy.mp.ArcGISProject('CURRENT')
lyt = p.listLayouts('Layout')[0]
lyt_cim = lyt.getDefinition('V3')
for elm in lyt_cim.elements:
    if type(elm).__name__ == 'CIMMapFrame':
        if elm.graphicFrame.borderSymbol.symbol.symbolLayers:
            sym = elm.graphicFrame.borderSymbol.symbol.symbolLayers[0]
            sym.width = 5
            sym.color.values = [255, 0, 0, 100]
        else:
            print(elm.name + ' has NO symbol layers')            
lyt.setDefinition(lyt_cim)
