[magick-users] Gradient howto

[Vu The Cuong]

Hi,

I have a couple of questions for you:

Below command generates gradient for text (not for background) for me.

        convert -size 850x80   gradient:white-blue \

        -font HoboBT-Regular -pointsize 70 -tile gradient:blue-red \

        -annotate +10+65 'Add Fonts to ImageMagick!' gradients.jpg

 

1) About "gradient:" prefix operator, (ex: gradient:white-blue), 

which command allow me how can I retrieve information about how many
operator begins with gradient: prefix

and what are they?

 

2) Above command example have gradient:blue-red which combines 2 colors
(blue and red),

Is there any operator allowing me to combine 3 colors or more on
generating gradient for text?

If no such operator, what is simplest way to generate gradient consists
of 3 colors for text?

 

3) Could you show me some commands to generate gradient consists of 3
colors for text?

I'll start learning from that.

Please help me. I need your help.

Many thanks and best regards,
