Next message: Dan Muey: "using png format"
my original message which received a 'pending' response follows at bottom.
i used Benchmark to time two subroutines- one using
Image::Size::imgsize(\$data), the other $img=Imager->new;
$img->open(data=>$data, type=>$type); $img->getwidth; $img->getheight.

original msg:
i really want to use Imager, but i need to do:
$img->open(data=>$data)
without the explicit type definition since i only am given the image data
in a buffer with no other knowledge. i currently use Image::Size to
determine height, width, and type. but Imager is 150% faster and has a
smaller memory footprint so i'd rather use it. it also has a feature i
now really need to use- image scaling.
so my question is: what is preventing automatic type detection from being
added? i see the comment in Imager.pm:
# FIXME: Find the format here if not specified
# yes the code isn't here yet - next week maybe?
# Next week? Are you high or something? That comment
# has been there for half a year dude.
# Look, i just work here, ok?
but should it not be a simple matter of snipping a bit of code from
Image::Size like the following bit?
my %type_map = ( '^GIF8[7,9]a' => \&gifsize,
"^\xFF\xD8" => \&jpegsize,
"^\x89PNG\x0d\x0a\x1a\x0a" => \&pngsize,
"^P[1-7]" => \&ppmsize, # also XVpics
'\#define\s+\S+\s+\d+' => \&xbmsize,
'\/\* XPM \*\/' => \&xpmsize,
'^MM\x00\x2a' => \&tiffsize,
'^II\x2a\x00' => \&tiffsize,
'^BM' => \&bmpsize,
'^8BPS' => \&psdsize,
'^PCD_OPA' => \&pcdsize,
'^FWS' => \&swfsize,
"^\x8aMNG\x0d\x0a\x1a\x0a" => \&mngsize);
thanks
