scritcher/doc

scritcher command reference

scritcher scripts are shell-like commands separated by a semicolon.

parameters of the arg type

some commands allow a :N syntax where N is an integer to use a given argument when scritcher is called. so, for example, calling a script:

load :0;
showpath;

and then doing scritcher path/to/script.scri arg will print arg on the screen and then exit.

split and index arguments

plugin commands have a split and an index argument so that you can select where in the file you want the plugin to be ran.

so, if you did plugin 3 1..., it would split the file in 3, then get the part that is of index 1 (starting at 0).

Keep in mind parts can start from either top or bottom of the image, it depends of the file format

load path_or_arg

Load a file into memory. The file MUST end with the bmp extension (and so MUST be a bmp. feel free to put other files, no warranties are given.)

tapedelay split index speed da_db t1d t1a_db...

TODO: gives 0 output

Correctly models the tape motion and some of the smear effect, there is no simulation fo the head saturation yet, as I don't have a good model of it. When I get one I will add it.
