POV 3.5 b 11 icl on WinNT Sp 6 PII 233 with 128 MB
Below example use macro kerning() from
http://news.povray.org/sa6q6u8ic6tt2ntql1kt4mm2fiebtf1pih%404ax.com.
The problem is:
1. start below script - it outputs <0,0,0> vector in message window
2. change Position at and of vletter macro to (Position) <- added parentheses
it outputs <3.5,0,0>
3. undo parantheses and remove first or second line of kerning macro
again <3.5,0,0> in output
3. undo removed line in above change and change warning to:
#warning Str(vletter("crystal.ttf","POV",0,3).x)
again <3.5,0,0> in output
4. remove included "strings" and change warning to:
#warning str(vletter("crystal.ttf","POV",0,3).x,0,-1)
again <3.5,0,0> in output
Could it be somehow releted to direct returning locals?
I though it was fixed in some beta. Any confirmation ?
//START
#macro kerning(Font,String,Thickness,Offset,Position)
#local HelpText=text{ttf Font String Thickness 0};
#local Text=HelpText;
#local Text=<version,0,0>;
Text
#end
#macro vletter(Font,String,Offset,Position)
#if(Position=1)
#local Position=(0*x);
#else
#local Position=kerning(Font,String,0,Offset,Position);
#end
Position
#end
#include "strings.inc"
#warning VStr(vletter("crystal.ttf","POV",0,3))
//END
ABX
