<GET_IMAGE	Attribute Description Table
When using ArcMap Server: autoresize ="true \| false" [false] dataframe ="string" When using Image Server: autoresize ="true \| false" [false] show ="layers" > <PROPERTIES... /> <ENVIRONMENT... /> (m) <LAYER... /> <WORKSPACES... /> [Image Server only] </GET_IMAGE >
Bold: Attribute or child element is required. (m): Child element can be used multiple times.

Description:

Sends a request to the Image Server to generate a map image.

Restrictions:

Valid workspace types include SHAPEWORKSPACE, IMAGEWORKSPACE, and SDEWORKSPACE and are valid with the Image Server only.

Notes:

See IMAGE for response.
For more details on using GET_IMAGE and IMAGE, including additional examples, see Using GET_IMAGE and IMAGE with Image Services or Using GET_IMAGE and IMAGE with ArcMap Image Services.

Attribute Descriptions for GET_IMAGE:

Attribute	Usage	Back to Top
dataframe	1 Valid with ArcMap Server only. Dataframe image to use when requesting map. By default, the selected image is the default data frame in the ArcMap document. However, alternate data frames can be accessed using this attribute.
autoresize	2 The maximum generated image size is based on the image memory limit set when an Image service is started. For example, an image memory limit of 1 MB allows a map no larger than 262,144 pixels (512 x 512) to be generated. If autoresize is set to "true", a requested map greater than the maximum pixel count will be reduced in size to within the maximum pixel count. If autoresize is set to "false", no image is generated and an error message is returned by the ArcIMS Spatial Server.
show	3 Use this attribute to return layer information in the response including layer ID, name, and number of features in the map.
