I have the wonderful "kolors.inc" but would like to see each of the 677
colors it contains. Each useful line begins with "#declare". Two examples:
  #declare OrangeRed            =  rgb <1.0000, 0.2800,0.0000>;
  #declare OrangeRed1           =  rgb <1.0000, 0.2695,0.0000>;


My idea is, to read each line of that file, and transform each line from
a definition to a cylinder showing the color specified in this line's
declaration.

But I don't know which scene commands I have to use, to achieve that.
Please help me. Thanks.

Sven

Hi to the Carribbean,

POV cannot parse files, since the read-directive didn't allow this. You can only
read in quoted strings.

The only idea I have to this is to edit the lines properly within an editor.

1. First declare two arrays and a counter:

#declare Names[677]
#declare Colors{677]
#declare Count=0;

2. Replace all '=' by a new symbol may be '$'
3. Replace all ';' by another new symbol may be '*'
4. Replace all '#declare ' by '#declare Names[Count]="'
   That is why one has to exchange the '=' first!
5. Replace all '$' by '"; #declare Colors[Count]='
6. Finaly replace the '*' by '; #declare Count=Count + 1;'

(Note that I used the apostrophes only to show begin and end of a string, dont
type them in within the find & replace dialog).

This should result in this:

  #declare Names[Count]" OrangeRed            "; #declare Colors[Count]=  rgb
<1.0000, 0.2800,0.0000>; #declare Count = Count + 1;
  #declare Names[Count]" OrangeRed1           "; #declare Colors[Count]=  rgb
<1.0000, 0.2695,0.0000>; #declare Count = Count + 1;

You may want to get rid of some blanks (replace two by one as long as possible
may be), but now you can iterate about the arrays Names and Colors or using the
frame_number during an animation.

Best regards,
Michael
