[SOLVED] How to find a list of methods(?)/operations in my version of Image::Magick?

Post by E. Fudd Wabbitwy »

I've been scratching out a Perl program using the Image::Magick module and have been proceeding, essentially, by finding and adapting small examples.

I'm running Perl5 on Ubuntu 18.04, and I believe my I::M module is ($image->Get('version')):
Version: ImageMagick 6.9.7-4 Q16 x86_64 20170114

Most recently, I tried to call a SetPixels() method, only to be informed:
"Can't locate auto/Image/Magick/SetPixels.al in @INC"

My questions:
1. How, inside a Perl/.pl script, to ask Image::Magick to display its list of accessible methods?
2. How, outside of Perl scripts, to find the I::M module (or related--something about "autoloading"?) and search it for a list of public methods?
and, I guess,
3. How can I get SetPixels() in my setup?

Thank you.

I do not use PerlMagick, but have you seen https://imagemagick.org/script/perl-magick.php

Indeed, yes. It was the mention of SetPixels() on that page which inspired my attempt to use it.

And, yes, I acknowledge that that page is, itself, a listing of accessible methods. However, in my case, at least some of them remain theoretical, and my goal is to ask the installed version of Image::Magic (aka PerlMagick) what it has, or to find out for myself by finding the Perl module (.pm file) and reading for myself.

Thanks!

My goal was to try to find out WHAT methods were available. In particular, I discovered that "setpixels" (plural) is not available in my setup, leading me to trying to install the latest version from source.

This works:

Code: Select all

use Class::Inspector;
use Image::Magick;

my $arrayref=Class::Inspector->methods('Image::Magick','full','public');
for (my $i=1;$i<=$#{$arrayref};$i++) {
print $#{$arrayref};
  print "$arrayref->[$i]\n";
}
exit;
