How about this one?

Is there a simple way to "use Image::Magic;" (aka PerlMagick, the Perl API to ImageMagick) to create a new "dummy" PNG image out of the ether; that is, no reading in an existing PNG file?

I've been trying for over a week and no matter what I've tried, the "magick" of files I create (which I take to be the file format: like 'PNG') come back as 'MIFF'.

I don't want to pollute the thread with my scattershot stuff that hasn't worked; if you've got a short example, please share.

I will say that my goal is to manipulate the file and Write it after it's created. I don't want to worry about how to "save as a PNG" after doing all the work, and instead, am hoping to create the write type of file before any work is started.

I hit "create" to stumbit and then this works, creating a 10x10 pixel PNG file, which is recognized as a PNG when written and read back in (I'm kinda like a novice monk who sits at the outermost gate talking to hisself): 

#!/usr/bin/perl

use Image::Magick;
my $image=Image::Magick->new(format=>'PNG',size='10x10'); # critical t
+o solution was this "format" key

my $err=$image->Read("canvas:orange");
warn "$err" if $err; # these are good ideas because PerlMagick sometim
+es fails silently

$err=$image->Write("CANVAS_ORANGE.png");
warn "$err" if $err;

my $other=Image::Magick->new;
my $err=$other->Read("CANVAS_ORANGE.png");
warn "$err" if $err;

my $format=$other->Get('format');
my $magick=$other->Get('magick');

print "Format:$format  Magick:$magick\n";
