hidden commands

[WarpEnterprises]

There are some commands in avisynth which I found when browsing through the sources which I can't figure out how exactly to use,...
There is nothing written in the docu either.
Maybe someone has an idea.
There are:

TRY and CATCH (which seem to belong together)

GLOBAL

\ for connecting to the next line (although in the doc it says the opposite)

RGBAdjust (maybe useful for the alpha mask as well?)

HSIAdjust

Histogram

<edit>: Forgot CACHE()

RGBAdjust:

Similar as Donald Grafts RGB filter with a fourth argument which indicated the alpha channel.

HSIAdjust:

Hue/Saturation intensity. See also http://forum.doom9.org/showthread.php?s=&threadid=28677

TRY and CATCH, GLOBAL, Histogram:
No idea how to use theae.

Aren't try and catch compiler features and not features of avisynth itself? I use try and catch in many jscripts that do file i/o in windows, as it allows you to trap errors and recover gracefully instead of having a script that just aborts and gives the user a cryptic error message. ie:

try {
var data = somefile.Read ( somebytes );
}
catch( e ) {
if ( e ) {flag_domyerror = true}
}

Perhaps there are "higher level" versions of these added into avisynth? I've never noticed them before, but that's probably because I never looked.

clip.histogram() just adds a histogram (line by line) to the right edge of the image. Give it a shot and see how it works.
