Installation

Click to download the ZIP file which contains the following files. Unzip this file, then put the files in the locations specified below. You will need write access to these locations.

File	Type	Location	Comments
imgexp	EXE	$ARCHOME/bin	The SID conversion executable
avmrsid.dll	DLL	$ARCHOME/lib	Library for the SID format functions
SIDEXTENT.AML	AML	$ATHOME/arcplot	Sets the map extent for a MrSID file
SIDIMAGE.AML	AML	$ATHOME/arcplot	Displays a MrSID image in an Arcplot window. Options to display include full image, selected portions or a specific extent.

$ARCHOME: ArcInfo Install directory
$ATHOME: ATOOLS Install directory

If you want to also use these tools in ArcEdit or GRID, you should additionally copy the AMLS into the respective ATOOL directory, i.e. $ATHOME/arcedit and $ATHOME/grid.

Usages

To be used in Arcplot, or whichever ATOOL directory you have copied the AMLS to.

SIDEXTENT <SIDfile>
Sets the current map extent to the extent of the SID file.
SIDIMAGE <SIDfile> {DEFAULT | FULL | * | <xmin> <ymin> <xmax> <ymax>}
Displays a SID file in the specified extent.

DEFAULT: Uses the currently set or default mapextent for extracting and displaying the MrSID image. This is the standard behavior you would get from using the IMAGE command.
FULL: Displays the full MrSID image, setting the mapextent to the full image
*: Allows interactive setting of the mapextent and the window to be displayed
<xmin> <ymin> <xmax> <ymax>: Expects the extents to be specified in mapunits for the area to be displayed

Notes

The .sid extension for the image name is required in each of the commands.
Display of the SID file will create a temporary file in your current workspace that will be removed after the image has been displayed. Every time the image is redrawn as a result of a pan, zoom, or other display canvas update, the temporary file will be recreated and again deleted.
These tools should be used for display only. Images drawn in this manner should not be put into a graphics file or attempted to be printed.
These tools do not interact in any way with any other commands. For example, LISTIMAGES will not list SID files, and none of the IMAGE related commands can be used with SID files.
