ArcGIS REST API - ArcGIS Services

Description

License:

As of 10.5, you must license your ArcGIS Server as an ArcGIS Image Server to use this resource.

The Raster Image resource returns a composite image for a single raster catalog item. You can use this resource for generating dynamic images based on a single catalog item.

This resource provides information about the exported image, such as its URL, width and height, and extent.

Apart from the usual response formats of html and json, you can also request a format named image for the image. When you specify image as the format, the server responds by directly streaming the image bytes to the client. With this approach, you don't get any information associated with the image other than the actual image.

Request parameters


Parameter	Details
f	The response format. The default response format is html. If the format is image, the image bytes are directly streamed to the client. Values: html \| json \| image
bbox	The extent (bounding box) of the exported image. Unless the bboxSR parameter has been specified, the bbox is assumed to be in the spatial reference of the image service. Syntax: <xmin>, <ymin>, <xmax>, <ymax> Example: bbox=-104,35.6,-94.32,41 The bbox coordinates should always use a period as the decimal separator, even in countries where a comma is traditionally used.
size	The size (width * height) of the exported image in pixels. If the size is not specified, an image with a default size of 400 * 400 will be exported. Syntax: <width>, <height> Example: size=600,550
imageSR	The spatial reference of the exported image. The spatial reference can be specified as either a well-known ID or as a spatial reference JSON object. If the imageSR is not specified, the image will be exported in the spatial reference of the image service.
bboxSR	The spatial reference of the bbox. The spatial reference can be specified as either a well-known ID or as a spatial reference JSON object. If the bboxSR is not specified, the bbox is assumed to be in the spatial reference of the image service.
format	The format of the exported image. The default format is png. Values: png \| png8 \| png24 \| jpg \| bmp \| gif
pixelType	The pixel type, also known as data type, that pertains to the type of values stored in the raster, such as signed integer, unsigned integer, or floating point. Integers are whole numbers; floating points have decimals. Values: C128 \| C64 \| F32 \| F64 \| S16 \| S32 \| S8 \| U1 \| U16 \| U2 \| U32 \| U4 \| U8 \| UNKNOWN
noData	The pixel value representing no information. Example: noData=0
interpolation	The resampling process of extrapolating the pixel values while transforming the raster dataset when it undergoes warping or when it changes coordinate space. Values: RSP_BilinearInterpolation \| RSP_CubicConvolution \| RSP_Majority \| RSP_NearestNeighbor
compressionQuality	Controls how much loss the image will be subjected to by the compression algorithm. Valid value ranges of compression quality are from 0 to 100. Example: compressionQuality=75

Example usage

Example 1: Return Raster Image (f=html) for raster ID 8:
