Just starting with ImageMagick after having used GD Library for decades and so far ImageMagick is far, far easier! However, I can’t seem to create a horizontal gradient in the first block in the code below. I would like it to start with medium gray and move to deep red but I’m not sure even how to begin.
The code is in three parts. The first contains the ImageMagick bits and it’s the first block with $Font1 where I want to do the gradient. The second file contains the variables and here you may have to use fonts on your system and adjust accordingly if trying it out. The third simply loads it into the browser for viewing so if all are placed together into a single folder, they should work for testing purposes. The last bit has a snippet in it which, if unremarked, will let you see your available fonts.
I understand what it needs in general but all attempts to do it give either an error or nothing at all so how do I proceed?
