Re: +clone and parens
It makes more logical sense to group your first commands and then clone, so the clone sees the result of the command not the input plasma image convert \( -size 100x100 plasma: -swirl 200 \) +clone +append x: So this should work fine. Since operators have left-associativity in convert, no grouping ...

Re: +clone and parens
This is a use-case for +clone in which I do not need to do further processing on the clone, hence there is no logical call for the grouping construct.

+clone and parens
Hello, I found that the +clone operator does not behave as I would expect when not enclosed in parens. I would expect the result of the first command given below to be similar to that of the second, where the right-hand clone is also swirled. I was surprised because this behavior seems to break with...

I can only guess that you are running an old PerlMagick.

Re: suggestion for blur and other effects
One solution in the mean time is to use a blur value that is say 0.00001 then 1.00001 etc in your sequence! The blur 0 is really a no-op but generally causes a error as it is also mathematically non-sensical. The shadow code for example had to have a 'short-circuit' to not do a blur when the shadow...

Re: Can't draw text using Annotate
NOTE: without a gravity, or some other appropriate offset the text is drawn. but with the 'baseline start point' at 0,0. Which mean only the bottom of the comma will probably be visible!!!!!! Try adding a +20+20 offset if you what to turn off gravity! Ah yes, that was it. Thanks. As per ghostscript...

Re: Can't draw text using Annotate
Gravity is only a specification of what the offset means. That is all. See Text Positioning with Gravity http://imagemagick.org/Usage/annotating/#text_gravity Perhaps I am observing a bug then. In the following program, if I remove the gravity from the Annotate, no text is drawn. #! /usr/bin/perl u...

problem with `Spread'
Hi. I'm unable to get Spread to vary with different values for the `amount' parameter. No matter what number I pass as the amount, the spread always appears to be about 4 pixels. Any ideas? Sample code follows. Thank you. #!/usr/bin/perl use strict; use warnings; use Image::Magick; my $image = Image...

Thank you. Both of those ways worked. I'm using PerlMagick so I went with the second way.magick wrote:Try one of the following:

Re: suggestion for blur and other effects
Thank you!
I found that giving Wave a 0 wavelength also results in a black canvas. The special case would probably be appropriate there, too.

Re: Can't draw text using Annotate
I found that I have to give Annotate a gravity setting like gravity=>'north'. try that.csharppmf wrote:The instruction:

suggestion for blur and other effects
Hi, I'm generating an animation in which I want to vary the amount of certain effects across frames, where some frames will be unaffected. I found that passing a sigma of 0 to GaussianBlur results in a black canvas, so I have to stop blurring at some small nonzero value. This means I can't quite get...
