#15 'Default' not working

[Håkan König]

The following script will generate an error:

function NTSC2PALresize(clip clip,int size)
{
s=default(size,576)
return bicubicResize(clip.width,s,0,0.5)
}

a=avisource(ntscvideo.avi)
NTSC2PALresize(a)

In v1.05 it would resize the video from 480 lines to 576
without requiring 2 arguments to the call.

This is not a bug. It shouldn't work. To make an argument
optional, you have to surround it with double quotes:

function NTSC2PALresize(clip clip,int "size")
{
s=default(size,576)
return clip.bicubicResize(clip.width,s,0,0.5)
}
a=avisource("ntscvideo.avi")
NTSC2PALresize(a)

When quoted, it also becomes a named argument; you can
also call it like that:
NTSC2PALresize(a,size=288)

I didn't know that before reading your report and testing a bit.
I'll update the doc, as I don't think it's mentionned anywhere.
