Zusammenfassung
The SVGFormat object represents a collection of Scalable Vector Graphics (SVG) file properties that can be configured and used with the export method on the Layout, MapFrame, and MapView objects to create an output SVG or SVGZ file.
Diskussion
SVG is an XML-based file format that has been specifically designed for viewing on the web. SVG can contain both vector and raster information. Some web browsers may require a plug-in to view SVG files; older browsers may not be able to view SVG files at all. SVG supports font embedding. You can also choose to produce compressed SVG files by setting the compressToSVGZ property to True. The file extension changes to *.svgz.
The createExportFormat method can be used to create a SVGFormat object if the format parameter is set to SVG. The returned SVGFormat object contains all the properties associated with a generating a SVG file. These properties can be modified accordingly to produce different output results.
Eigenschaften
| Eigenschaft | Erläuterung | Datentyp |
| clipToElements (Lesen und schreiben) | If set to True, include the areas of the page that have map or layout element content only, rather than exporting the entire page. This property only applies when exporting a Layout object. The default value is False. | Boolean |
| compressToSVGZ (Lesen und schreiben) | If set to True, the file is compressed and the extension should be set to *.svgz. The default value is False. | Boolean |
| convertMarkers (Lesen und schreiben) | Controls whether marker symbols based on font characters are exported as font characters or as polygons. Set this option to True to view the output on a machine that does not have the appropriate fonts installed when you cannot embed the fonts due to licensing or file format restrictions. This does not apply to text, only marker symbols based on fonts. The default value is False. | Boolean |
| embedFonts (Lesen und schreiben) | Include embeddable fonts in the exported file to maintain font consistency across different platforms. Fonts that do not support embedding are not included, regardless of this setting. The default value is True. Hinweis:To correctly edit text as graphics, Illustrator requires fonts to be installed and accessible. Check the sharing permissions before embedding and sharing fonts. | Boolean |
| filePath (Lesen und schreiben) | A string that represents the system path and file name, including the extension, for the exported file. | String |
| height (Lesen und schreiben) | The height, in pixels, of the map area to be exported. This property only applies when exporting a MapView object. The default value is 960. | Double |
| imageQuality (Lesen und schreiben) | The amount of image resampling. The property determines the effective resolution of raster content on output. For instance, if imageQuality is set to BETTER, a resample ratio of 1:2, and the output resolution is set to 300 dpi, the raster content is output at approximately 150 dpi. In many cases, the raster data can be included at a lower dpi than the vector data without visibly affecting quality, reducing the output file size. The default value is BEST.
| String |
| includeNonVisibleMapLayers (Lesen und schreiben) | If set to True, this property ensures that all layers in the map are included in the exported file, including layers with visibility unchecked. The visibility status of all layers is retained in the exported file. Use this option to create deliverables with several views of the same data. When this property is set to False, only visible layers in the map are included in the exported file. Non-visible layers are dropped. The default value is False. | Boolean |
| outputAsImage (Lesen und schreiben) | Export vector content as an image. For maps or layouts containing vector layers with a high density of vertices, this can drastically reduce the output file size. The default value is False. Hinweis:Options specific to vector data, such as embedFonts, are unavailable when outputAsImage is set to True. | Boolean |
| resolution (Lesen und schreiben) | The effective dpi of the output vector data. The default value is 96. Hinweis:When exporting a MapView, the dpi is calculated automatically using system dpi scaling and therefore this value will be ignored. | Integer |
| showSelectionSymbology (Lesen und schreiben) | Show selected features in the map or map frame as selected in the output file. Setting this value to False does not affect selection within the view, only in the output file. The default value is False. | Boolean |
| width (Lesen und schreiben) | The width, in pixels, of the map area to be exported. This property only applies when exporting a MapView object. The default value is 960. | Double |

| String |
The value determines the effective resolution of raster content on output. For instance, if the output image quality ratio is set to 1:2, an image_quality value of BETTER, and the output resolution is set to 300 dpi, the raster content is output at approximately 150 dpi. In many cases, the raster data can be included at a lower dpi than the vector data without visibly affecting quality, reducing the output file size.
Codebeispiel
The following script exports a layout to SVG format using default property values.
p = arcpy.mp.ArcGISProject('current')
lyt = p.listLayouts()[0]
svg = arcpy.mp.CreateExportFormat('SVG', r'C:\Temp\Output.svg')
lyt.export(svg)The following script exports a layout to compressed SVG format by setting the compressToSVGZ property to True.
p = arcpy.mp.ArcGISProject('current')
lyt = p.listLayouts()[0]
svg = arcpy.mp.CreateExportFormat('SVG', r'C:\Temp\Output.svgz')
svg.compressToSVGZ = True #Change from default value of False
lyt.export(svg)
