hsl not working as expected

[daviddoria]

I am trying to make a block a certain hsl color. This works with rgb (creates a red image 200x100):

Code: Select all

convert -size 200x100 xc:rgb\(255,0,0\) rgb.png

I thought this would do exactly the same thing:

Code: Select all

convert -size 200x100 xc:hsl\(0,100%,50%\) hsl.png

but it produces a black image. Why is that?

Thanks,

We get a red image as expected. We're using ImageMagick 6.5.1-7, the current release.

put any colors specified as rgb or hsl in quotes, e.g. xc:"hsl(0,100%,50%)"

see http://www.imagemagick.org/script/color.php

What IM version are you using? Perhaps it is too old.

Same black result with the quotes:

Code: Select all

convert -size 200x100 xc:"hsl(100,100%, 50%)" square.png

I'm using
ImageMagick.i386 6.4.0.10-2.fc10

I'll try upgrading, but it seems odd that it would not give an error and just not work?

I get using IM 6.5.1-7 Q16 Mac OSX Tiger:

convert -size 200x100 xc:"hsl(100,100%, 50%)" green_box.png

Here's my result of the same green_box command:

could have been a bug in your old version of IM. try upgrading.
