Bug #21770 for Imager: $image->string( string => "0", ... ) is a noop.

Thu Sep 28 16:36:28 2006 RBS [...] cpan.org - Ticket created

Subject:

$image->string( string => "0", ... ) is a noop.

We've had to add the following workaround in a string display routine to get a string containing a single zero ("0") to display. Also, passing in a chr( 0 ) seems to cause a premature end of string to be found. $text .= " " if length $text && !$text; ## Imager declines to display "0" $image->string( color => \@color, font => $font, string => $text, x => $self->get_x, y => $self->get_y + $global_ascent, );

Sorry about the delay in getting back to you on this, work has been keeping me busy. I'll take a look at this as soon as I get the chance. Tony

Tony: low urgency for me; the workaround for "0" (digit zero) works for us and I don't know of any fonts that map anything to ASCII NUL (chr( 0 )). - Barrie via RT wrote: Show quoted text

This is fixed in current svn, available from: http://imager.perl.org/svn/trunk/Imager Show quoted text

Were you using the Win32 font support here? ie. creating a font with: my $font = Imager::Font->new(face => $facename); as opposed to one of the font file drivers where you supply a filename: my $font = Imager::Font->new(file => $font_file_name); If this was a problem with one of the file based drivers, please let me know which driver, so I can track it down. If it was the Win32 driver then the problem is fixed in current svn. Thanks for reporting these problems, and sorry about taking so long to fix them. Tony

This is on Win32, using the "face => $facename" API. And no worries about the time lag, our code is working fine without the fixes (the first has a workaround, the second was observed only while testing the first). - Barrie via RT wrote: Show quoted text

Sorry for the delay in fixing this. This problem has been fixed in Imager 0.55. Thanks for your report. Tony
