Change the resolution of output JPEG images from Spatial Server

Last Published: April 25, 2020


JPEG images produced by the Spatial Server have a default resolution of 85%. You can change this value as shown here.


Open the aimsms.cfg file in a text editor, such as WordPad. This file is located in the etc directory wherever your Spatial Server is installed.

type = "ImageServer"
description = "This is an ImageServer"
exe = "MapServer\aimsms.dll"
access = "PUBLIC"
<parameter name="jpegquality" value="85" />
<parameter name="giflicense" value="GIF keycode" />

In the aimsms.cfg file, change the value for "jpegquality" to a desired output resolution between 1% and 100%. In the above example, the value is set to 85%.

Save the file and restart all the ArcIMS services.
