Thank you, Anthony!

Your response is very detailed, as always
Though I still can't speed up the process of the gif generation.
But your response give me ideas to experiment.

Hi, My task is to generate gif animation from 3 images. Here they are: http://www.picamatic.com/show/2011/08/04/11/08/7751531_500x336.jpg http://www.picamatic.com/show/2011/08/04/11/15/7751540_500x336.jpg http://www.picamatic.com/show/2011/08/04/11/15/7751541_500x336.jpg I use PerlMagick: my $gif = ...

Thank you!

But, according to PerlMagick tutorial there is no parameter luminosity in Modulate.
There are only brightness, saturation, hue, lightness, whiteness and blackness.
I also can't find parameter luminosity in other functions.

Hello,

Please, help me to resolve problem with lightness.

It seems $img->Modulate( saturation=>'0', lightness=>'150') doesn't work in Perl.
It works the same like $img->Modulate( saturation=>'0').

Is it a bug or is their any other way how to implement lightness?

Hello, guys. Please, explain the issue. After update from 6.4.6 to 6.5.6-10 there is a strange behavior of the "Scale" function for PNG image with transparency. After making "Scale" and "Composite" white border appears. Original image http://www.picamatic.com/show/2009/...

Sorry guys, but still nothing. 6.5.6-9 is the latest available release.

Thanks for the prompt response!
I've just upgrated to 6.5.6-9. The problem remained

Hello, guys. Please, help me to understand where the problem is. The problem arised after I've upgraded IM from 6.4.5 to 6.5.6-7. After that white rectangle appeared on the gif below. http://i.piccy.info/i4/21/75/9b07df0c2a622c3b7285fda10079.gif Original image http://i.piccy.info/i4/ee/c4/e3f3fb3472...

I just made
#svn co https://www.imagemagick.org/subversion/ ... gick/trunk ImageMagick

The last record in ChangeLog was made on 2009-08-31 for version 6.5.5-6
Is ChangeLog not up-to-date?
Also, how do you think, is it safe to roll out 6.5.5-8 on production server?

Many thanks! I wonder, that nobody needs it before
But I have framework on Perl and use perl-magick. Is it possible to add "-interline-spacing" as a parameter to Annotate function?

Hello! please, help me to find out how annotation works. I need to write text vertically. I just write text in a usual way using "\n", like "A\nB\nC\n". The problem is how to control vertical distance between the characters. Something similar to line-height in HTML. Could you ple...

It tried this
$img->Threshold( channel => 'GB', threshold => '101%');
and it also works!

Anthony, may be you have any thoughts about brightness?
It is very annoying problem. Did you every see anything similar?

Thank you for such detailed response! I use this perl code my $res = $img->Threshold( channel => 'Red', threshold => '101%'); my $res = $img->Threshold( channel => 'Blue', threshold => '101%'); and it works fine. Does anybody have suggestions about brightness? This is very odd problem, but it really...

Hello. I try to write perl script that is analogue to: convert rose: -channel RB -fx 0 channel_red.gif When I try to use $img->Fx() there is no effect, and when I use img->Mogrify( 'fx', ... ) I get Exception 410: unrecognized PerlMagick method `fx' @ Magick.xs/XS_Image__Magick_Mogrify/6497 Please, ...

Could you please advise how to get color of the specific pixel using Perl API
I tried the following
@a = $img1->Get('pixel[10x10]');
but
$img2->Colorize( fill => \@a );
always colorize with black color
I, actually, need to colorize image with the specific pixel color.

Thank you!
