ExportToAI (arcpy.mapping)

摘要

以 Adobe Illustrator (AI) 格式导出地图文档 (.mxd) 的页面布局或数据框。

讨论

Adobe Illustrator (AI) 文件格式特别适用于 Adobe Illustrator 中的后处理,还适合用作发布时使用的交换格式。ArcMap AI 格式可保留 ArcMap 内容列表中的大多数图层。但是,ArcMap 写入的 Adobe Illustrator 文件格式并不支持字体嵌入,因此尚未安装 Esri 字体的用户可能无法使用正确的符号系统查看 AI 文件。从 ArcMap 中导出的 AI 可以通过 CMYK 值或 RGB 值定义颜色。

要导出单个数据框(而不是整个页面布局),可将 DataFrame 对象传给函数的 data_frame 参数。由于数据框导出不具有可提供高度和宽度信息的关联页面,所以必须通过 df_export_widthdf_export_height 参数来提供此信息。

对于页面布局导出和数据框导出,控制生成图像图形质量的方式有所不同。导出页面布局时,通过更改 resolution 参数来控制图像细节。导出数据框时,保持 resolution 参数的默认值,更改 df_export_widthdf_export_height 参数来更改图像细节。高度和宽度参数直接控制在导出文件中生成的像素数,且仅在导出数据框时使用。像素数较高的图像具有较高的图像细节。对于大多数页面布局导出,默认参数值应在第一次尝试时生成良好的结果和美观的导出图像。对于数据框导出,您可能需要对 df_export_widthdf_export_height 值进行若干次试验,之后才能得到理想的结果。

语法

ExportToAI (map_document, out_ai, {data_frame}, {df_export_width}, {df_export_height}, {resolution}, {image_quality}, {colorspace}, {picture_symbol}, {convert_markers})
参数说明数据类型
map_document

A variable that references a MapDocument object.

MapDocument
out_ai

A string that represents the path and file name for the output export file.

String
data_frame

A variable that references a DataFrame object. Use the string/constant "PAGE_LAYOUT" to export the map document's page layout instead of an individual data frame.

(默认值为 PAGE_LAYOUT)

Object
df_export_width

A number that defines the width of the export image in pixels for a data frame export. df_export_width is only used when exporting a data frame. Exporting a page layout uses the map document page width instead of df_export_width.

(默认值为 640)

Integer
df_export_height

A number that defines the height of the export image in pixels for a data frame export. df_export_height is only used when exporting a data frame. Exporting a page layout uses the map document page height instead of df_export_height.

(默认值为 480)

Integer
resolution

A number that defines the resolution of the export file in dots per inch (DPI).

(默认值为 300)

Integer
image_quality

A string that defines output image quality, the draw resolution of map layers that draw as rasters.

  • BESTAn output image quality resample ratio of 1.
  • BETTERAn output image quality resample ratio of 2.
  • NORMALAn output image quality resample ratio of 3.
  • FASTERAn output image quality resample ratio of 4.
  • FASTESTAn output image quality resample ratio of 5.

(默认值为 BEST)

String
colorspace

A string that defines which color space will be written to the export file.

  • CMYKCyan, Magenta,Yellow, and blacK color model.
  • RGBRed, Green, and Blue color model.

(默认值为 RGB)

String
picture_symbol

A string that defines whether picture markers and picture fills will be converted to vector or rasterized on output.

  • RASTERIZE_BITMAP Rasterize layers with bitmap markers/fills.
  • RASTERIZE_PICTURERasterize layers with any picture marker/fill.
  • VECTORIZE_BITMAPVectorize layers with bitmap markers/fills.

(默认值为 RASTERIZE_BITMAP)

String
convert_markers

A Boolean that controls the coversion of character-based marker symbols to polygons. This allows the symbols to appear correctly if the symbol font is not available or cannot be embedded. However, setting this parameter to True disables font embedding for all character-based marker symbols, which can result in a change in their appearance.

(默认值为 False)

Boolean

代码实例

ExportToAI 示例 1

此脚本使用所有选项的默认值打开地图文档并将页面布局导出为 Adobe Illustrator 文件。

import arcpy
mxd = arcpy.mapping.MapDocument(r"C:\Project\Project.mxd")
arcpy.mapping.ExportToAI(mxd, r"C:\Project\Output\Project.ai")
del mxd
ExportToAI 示例 2

与从 ArcMap 应用程序的数据视图中导出类似,此脚本将导出单个数据框(而不是整个页面布局)。df_export_widthdf_export_height 的默认值分别是 640 和 480。通过传递这些参数的较大值,可以生成细节层次较高的输出图像。

import arcpy
mxd = arcpy.mapping.MapDocument(r"C:\Project\Project.mxd")
df = arcpy.mapping.ListDataFrames(mxd, "Transportation")[0]
arcpy.mapping.ExportToAI(mxd, r"C:\Project\Output\ProjectDataFrame.ai", df,
                         df_export_width=1600,
                         df_export_height=1200)
del mxd
