Set various options related to Projects.
Project width
Save Project settings
Project width determines how wide the project window will be. If set here, project windows will be this size whenever they are opened for the remainder of the current session. If the value (y/n)vis saved with the Save Parameters button, then this width will be used in subsequent sessions as well.
If Save project settings is set to yes, then the value of each of the check boxes, plus any variables that have been assigned, will be saved in the project file when it is closed in the current session. If this value (y/n) is saved with the Save Parameters button, then the value will be the same for subsequent sessions as well.
Create/Edit/Save a map or image color table
[None]
This function calls up the Color Table Editor in a separate window. If a color table has already been selected by another function, that color table will be shown in the spreadsheet in this window. The menu options available for creating, editing and saving color tables are described below. Individual cells within the spreadsheet can be edited by first clicking on the desired cell, and then modifying the value therein. Clicking on a color cell will bring up a color selection tool that can be used to select one of the 16 basic EGA colors. Other colors are available by modifying any of the red, green or blue values.
See color tables for a more detailed description of color tables. The limitations on possible colors is important. See the IDA Users Manual for a description of IDA LUTs and palettes.
Note that a color table is a simple ASCII text file that can be edited in any text editor, including WinDisp3.5.

If you are always displaying images or maps of the same area, you can use this command to tailor the size of the window to fit your area of interest. If you save these parameters to the ini file then they will be used each time you use WinDisp.
File-based communications link to other program
Input directory
Output directory
Interval (milliseconds)
This option can be used to establish a file-based communications link to another program. This was developed so that a Web server can call WinDisp3 and request it to display images and maps and return a GIF bitmap of the result.
The communications process is as follows:
- 1. The calling function places a file with a .lck extension in the input directory.
- 2. The calling function places a file with a .req extension in the input directory. This file should be a batch file that WinDisp3 is to execute.
- 3. The calling function removes the .lck file thereby signifying that the .req file should be processed.
- 4. WinDisp3 creates a .lck file in the output directory.
- 5. WinDisp3 opens and executes the .req batch file creating any requested outputs.
- 6. WinDisp3 closes the .req file in the input directory, deletes it, and deletes the .lck file in the output directory signifying that it has completed execution.
The Interval parameter specifies how often WinDisp3 should poll the input directory to check for .lck and .req files.
