Hi,

i´m trying to use the CopyToGD function to "convert" a DIBitmap to a GD

Win32-GUI-DIBitmap

Here is what i've got.
use Win32::API;
use Win32::GUI::DIBitmap;
use GD;

$GetDC                 = new Win32::API('user32','GetDC',['N'],'N');

my $dc      = $GetDC->Call(0);
my $dib     = newFromDC Win32::GUI::DIBitmap ($dc);
my $width   = $dib->GetWidth() ;
my $height  = $dib->GetHeight() ;
my $GDimage = new GD::Image($w,$h);
$dib->CopyToGD($GDimage,$dib) ;

#do something with the gd object 
#....

open (DISPLAY, ">test.png");
binmode DISPLAY;
print DISPLAY $GDimage->png;
close (DISPLAY);

[download]

I keep getting the error:
gd-png:  fatal libpng error: Image width or height is zero in IHDR
gd-png error: setjmp returns error condition

Any ideas what i´m missing?
Thanks
