Subject: Re: TkPhotoImage.copy always gives "too many colors" Error

Yes, I am certainly willing to try :format, however I only have PERL 
examples and adding

   , :format => 'jpeg'

to the end of both TkPhotoImage.new() calls ends up with the same error. 
I tried :jpeg and :jpg also, though for :jpg it says that format is not 
supported.  I also tried all the permutations of adding :format between 
the 2 .new() calls and get the same error each time.

I added a puts in tk/image.rb's write(), but that just shows that it is 
going to the correct filename with no options specified.  I could try 
higher up in the stack (4 more methods) but they are all there just to 
call the Tk underbelly, right?

Locally I see that /ruby/1.8/tkextlib/tkimg/jpeg.rb exists.  I realize 
that this is the first time I've tried saving an image from Ruby/Tk, 
however given the focus of your comment should I assume that my code at 
least looks correct?  So is the conclusion that the ActiveTcl 
implementation (the only one available for Windows, I've heard, a 
commercially dependant binary) has errors?


Thanks,
