well, it doesn't work for me either. It seems that Wx::Image is not the current version of wx-perl. I've downloaded the lastest CPAN version (0.22) of Wx and I tried to install Wx::Image, but both failed in during the tests. So I installed the debian package of wx-perl. But no Wx::Image..
maybe not everything has been ported from the wxwidgets 2.5 API? I have no idea...
Actually a separate 'use Wx::Image' is now no longer needed (even gives an error). There were some other things that stopped working. I made some fixes and you may download a working version from the wxPerl Wiki.
Don't let this stop you from using wxPerl, it's actually pretty good.
I got this to work on wxPerl with wxWidgets release gtk2-unicode-release-2.6 and WxPerl 0.27 with the following changes (line numbers are approximate depending on how you copy the source).
Line 35: remove "use Wx::Image" -- it's integrated now
Line 47: change to an image I have.
Line 54: change $bmp = $image->ConvertToBitmap(); to $bmp = Wx::Bitmap->new($image);
Line 144: remove use Win32; and use HTML::SimpleLinkExtor;
Line 168: remove $dir=Win32::GetShortPathName($dir);
Line 204: Same change as line 54 above.
Line 214: Remove $parent->Clear()
It runs without crashing, but the ScaleImage doesn't work yet.
