I've been asking a few questions regarding Tk lately, and once again, this has to do with Tk.

I have a lot of GIF images, and they all are displayed as buttons. To view them in a matrix of 4x4, they are all resized to a certain $MAX_HEIGHT and $MAX_WIDTH like this:
        $images[$y] = $mainframe->Photo(-file => "$file.gif");
        my ($height, $width) = ($images[$y]->height, $images[$y]->widt
+h);
        my $yfactor = $height/$MAX_HEIGHT;
        my $xfactor = $width/$MAX_WIDTH;
        my $scalefactor = $xfactor > $yfactor ? int($xfactor) : int($y
+factor);
        $scalefactor +=1;
        my $scaledimage = $mainframe->Photo("button$y");
        $scaledimage->copy($images[$y], -subsample => $scalefactor);
        $images[$y]->destroy();

this snippet of code is executed within a loop (that's why the @images exists)...

The problem I have is that I actually want all images to have the exact same width. With this code (using $scaledimage->copy($images[$y], -subsample => $scalefactor) it's only possible to use integers as $scalefactor.
I know I can use PerlMagick to resize images, save them and reload them again, but that takes two more disk-actions, and the whole thing isn't that fast already.

Is is possible to scale an image in Tk with 'floats' ? Rescaling with integers makes images either large or small...
