Subject: [cl-gd-devel] CL-GD and LispWorks 5.1: Loading images with extended
 characters in their pathnames?
Message-ID: <4C93D4B9.6040104@medialab.com>

Hello,

If I have a pathnamewith extended characters in its namestring (like
curly quotes, etc), how do I get that image to load with CL-GD?

Maybe I have to go diving into UFFI or the sources for GD itself, but I
thought I'd ask here first, since it seems like this has probably come
up already.

Thanks for any assistance,

Chris



Example:  f => #P"/Users/cperkins/Pictures/image file names
testing/Earth ?fatter? copy.gif"

(cl-gd:create-image-from-file f)


Error: External format (:LATIN-1 :EOL-STYLE :LF) got error writing
#<Pointer to type (:UNSIGNED :CHAR) = #x0102B008> at position 55: No
encoding exists for character ?.
  1 (abort) Return to level 0.
  2 Return to top loop level 0.

Hi  Chris,

I don't see which of the characters in the file name would not have an
encoding in Latin1.  Is this really the file name you used?

The problem is, though, that UFFI doesn't allow you to specify an
encoding when converting Lisp strings to C strings.  This could
certainly be done in the LispWorks FLI directly and probably (I
haven't looked) in CFFI as well.  A real solution would be to
re-architect CL-GD to use an alternative to UFFI, but I don't have the
time to do it and I haven't used CL-GD for years anyway.

Cheers,
Edi.
