FileImaging Terminal is console version of FileImaging that allows you to use base program features from Windows command-line (console). Terminal version can convert any pattern back to file and can create password-protected patterns. At the moment alpha-version does not support FileImaging Extensions.

Convert any file to pattern by using the following:
FileImaging Terminal.exe <file name> <pattern type> [-p <password>]
where <pattern type> is:
0 for grayscale pattern
1 for alpha-grayscale pattern
2 for RGB pattern
3 for ARGB pattern (recommended)
you can use the tag -p to give any pass string for a pattern (optional)
Tags --password and --pass works the same

Convert any pattern back to file by using the following:
FileImaging Terminal.exe <pattern png name>
