Subject: Export wxMemory{In,Out}putStream
wxMemoryInputStream seems to be the missing piece to be able to build a Wx::Image from JPEG data contained in a memory buffer. Use case: I need this to build an photo managing application. I'm extracting the thumbnail data from the JPEG files using Image::ExifTool. The thumbnail data itself is encoded as a JPEG. This could also be used to display images loaded from file using other Perl libraries instead of the wxWidgets libraries. -- Olivier Mengué - http://search.cpan.org/~dolmen/ http://github.com/dolmen/

Hi, Untested, but you may like to give the following a try my $jpegdata = <rawjepgdata> open my $file, '<', \$jpegdata; my $handler = Wx::JPEGHandler->new(); my $image = Wx::Image->new(); $handler->LoadFile( $image, $file ); Mark On 18/02/2011 19:36, Olivier 'dolmen' Mengué via RT wrote:

The code above should work; using open my $fh, '<', \$data; my $img = Wx::Image->new( $fh, wxBITMAP_TYPE_JPEG ); should work as well (it's part of wxPerl test suite). Regards, Mattia

Thanks Mattia. It works! It's great to have such a good integration of Wx with Perl. I'm closing the bug. -- Olivier Mengué - http://search.cpan.org/~dolmen/ http://github.com/dolmen/
