Gravity center, caption and wrapped text

[sorpigal]

Using ImageMagick on the command line I can say

Code: Select all

convert -background '#0000' -fill white -stroke black -strokewidth 3 -gravity center -pointsize 78 -size 568x1000 caption:'Lorem ipsum etc etc' -trim out.png

To produce precisely the output I'm looking for. What I'd like to do is the same thing but within PerlMagick so that I don't have to keep reading and writing files as I perform various other steps. Here's what I have so far:

Code: Select all

use strict;
use warnings;
use Image::Magick;

my $im = new Image::Magick;
my $e = $im->Set(
        background => '#0000',
        fill => 'white',
        stroke => 'black',
        strokewidth => 3,
        gravity => 'center',
        pointsize => 78,
        size => '586x1000',
);
die $e if $e;

$e = $im->Read("caption:Lorem ipsum etc etc");
die $e if $e;

$e = $im->Trim();
die $e if $e;

$e = $im->Write('out.png');
die $e if $e;

And this produces the same output, except that the resulting text is not centered.

The only documentation on doing caption from PerlMagick that I could find used a syntax which is certainly wrong and didn't work when I tried it. (It was essentially the same as the above, only calling Write instead of Read.) I based this "read caption" syntax on some MagicWand examples, where it is claimed that this will result in centered text. Clearly something is different for PerlMagick.

So, the question: How can I make PerlMagick respect gravity in this case? How do I get multi-line, centered and word-wrapped text via PerlMagick?

Any insight you could share would be extremely helpful.

Well you are quite correct in that gravity does not appear to work.

The documentation lists gravity with capitals, but it should be case-insensitive, and using capitals does not make any difference.

From my understanding it should work.

Moving this topic to 'Bugs'.

We can reproduce the problem you posted and have a patch in ImageMagick 6.6.5-6 Beta available by sometime tomorrow. Thanks.
