RE: Prima beginner issues

Hi,

I feel I have some image library issues even now.
I have installed
1. Prima 1.22
2. Prima-prigraph-win32-1.01 from CPAN.
 Hope this is enough for having atleast gif library on windows.

3. I have Windows xp
4. I have Visual studio 6.0

The code below throws me the error ;"Error Saving: No appropriate codec
found"

  use Prima qw(Application);

   # create a new image from scratch
   my $i = Prima::Image-> new(
      width => 32,
      height => 32,
      type => im::BW, # same as im::bpp1 | im::GrayScale
   );

   # draw something
   $i-> begin_paint;
   $i-> color( cl::White);
   $i-> ellipse( 5, 5, 10, 10);
   $i-> end_paint;

   # mangle
   $i-> size( 64, 64);

   # file operations
   $i-> save('paint.gif') or die "Error saving:$@\n";
   $i-> load('paint.gif') or die "Error loading:$@\n";

I know the easiest way is to switch to Linux. But I have to use Windows
now.

Please show me some way out.

Cheers,
Jis

First (this will not fix the problem, but is an issue anyhow): if you
are running on windows delete the shebang line or fix it to point to
your perl interpreter.

Then, on my environment (linux) the snippet runs smoothly exiting doing
nothing, I get the error only if the image is not in the current path:
are you really sure about this ? Try with the absolute image path.
