TIFFFormat

サマリー

The TIFFFormat object represents a collection of Tagged Image File Format (TIFF) file properties that can be configured and used with the export method on the Layout, MapFrame, MapView, MapSeries and BookmarkMapSeries objects to create an output TIF file.

ディスカッション

TIFF files are the best choice for importing into image editing applications and are also a common GIS raster data format. However, they cannot be natively viewed by a web browser. TIFFs also support georeferencing information in GeoTIFF tags or in a separate world file for use as raster data.

The createExportFormat method can be used to create a TIFFFormat object if the format parameter is set to TIFF. The returned TIFFFormat object contains all the properties associated with a generating a TIFF file. These properties can be modified accordingly to produce different output results.

プロパティ

名前	説明	データタイプ
clipToElements (読み取り/書き込み)	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
colorMode (読み取り/書き込み)	A string constant that represents the number of bits to describe color in a pixel. The default value is `24-BIT_TRUE_COLOR`. 1-BIT_MONOCHROME_THRESHOLD—2 possible colors, black and white. The areas which are white and black are determined by the `threshold` value. 8-BIT_ADAPTIVE_PALETTE—Uses 256 of the most commonly-used pixel colors in the image’s palette, thereby minimizing the number of pixels whose color may change during output. 8-BIT_GRAYSCALE—256 shades of gray. All colors are converted to grayscale. 24-BIT_TRUE_COLOR—16,777,216 possible colors. This option is good for maximum color fidelity. 32-BIT_WITH_ALPHA—16,777,216 possible colors and an alpha (transparency) channel of 255 values. This option is useful for maps or layouts with transparency. 32-BIT_CMYK_TRUE_COLOR—8 bits per pixel for each channel: cyan, magenta, yellow, black. 40-BIT_CMYK_WITH_ALPHA—8 bits per pixel for each channel: cyan, magenta, yellow, black, plus an additional 8-bit channel for alpha. Use this option if maps or layouts have transparency. 注意: The available `colorMode` values are dependent on the specified color model set in color management properties. The `32-BIT_CMYK_TRUE_COLOR` and `40-BIT_CMYK_WITH_ALPHA` options are only available if the layout or map has a CMYK color model. Similarly, the `24-BIT_TRUE_COLOR` and the `32-BIT_WITH_ALPHA` options are only available if the layout or map has a RGB color model.	String
embedColorProfile (読み取り/書き込み)	Include the color profile set for the map or layout in the exported file. This helps create consistency in colors when the file is viewed on different devices. If the profile is not embedded, or a non-color-managed viewer is used, the colors may be significantly different than what is seen on-screen. The default value is `True`. 注意: This option is only available when color management is enabled. If color management is not enabled and the colorspace is set to CMYK, the CMYK colorspace is still included in the export. This may cause some colors to appear differently when viewing the exported file.	Boolean
filePath (読み取り/書き込み)	A string that represents the system path and file name, including the extension, for the exported file.	String
geoReferenceMapFrame (読み取り/書き込み)	The MapFrame used to control the coordinate system when the `worldFile` property is set to True. The default value is `None`.	MapFrame
geoTIFFTags (読み取り/書き込み)	If set to `True` and a valid `georef_mapframe` is set, geoTIFF tags will be embedded in the resulting image based on the map frame's coordinate system. This allows the exported image to be used as raster data in ArcGIS Pro or other GIS applications. The default value is `False`. 注意: When exporting a layout, the GeoTIFF information needs to be based on a 2D map associated with the `geoReferenceMapFrame` property. The `geoTIFFTags` property is independent from the `worldFile` property. With GIS-capable software, you can honor the GeoTIFF information or the world file for these exports.	Boolean
height (読み取り/書き込み)	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
imageCompression (読み取り/書き込み)	A string constant that represents the compression scheme used to compress image or raster data in the output file. The default value is `LZW`. DEFLATE—Lossless compression method that works well for most cases. JPEG—Lossy compression method that works well for photographic-type images. LZW—Lossless compression method using a code table. NONE—Compression is not applied. PACK_BITS—Lossless compression method that works well if there are large areas of the same color.	String
imageCompressionQuality (読み取り/書き込み)	The amount of image compression applied to the export. Low quality has a smaller file size but less clear data; max quality has a larger file size but crisper data. This only applies when certain compression types are used. The default value is `100`.	Integer
resolution (読み取り/書き込み)	The effective dpi of the output vector data. The default value is 96. 注意: When exporting a `MapView`, the dpi is calculated automatically using system dpi scaling and therefore this value will be ignored.	Integer
showSelectionSymbology (読み取り/書き込み)	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
threshold (読み取り/書き込み)	Image intensities set above this value will appear white in the output file and all other values will appear black. This property is applied only when the `colorMode` property is set to `1-BIT_MONOCHROME_THRESHOLD`. The default value is `128`.	Boolean
transparentBackground (読み取り/書き込み)	If set to `True`, the white page background is set to transparent. The default value is `False`.	Boolean
width (読み取り/書き込み)	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
worldFile (読み取り/書き込み)	If set to `True` and a valid `georef_mapframe` is set, a world file will be generated based on the map frame's coordinate system. The default value is `False`.	Boolean

`setColorMode(color_mode)`

A string constant that represents the number of bits used to describe color.

The 32-BIT_CMYK_TRUE_COLOR and 40-BIT_CMYK_WITH_ALPHA options are only available if the layout or map has a CMYK color model. Similarly, the 24-BIT_TRUE_COLOR and the 32-BIT_WITH_ALPHA options are only available if the layout or map has a RGB color model.
