Feature request: line height and kern

[haydenzone]

Howdy!

First off, I've been using this library for a couple hours and it's great. I appreciate all the work that has been put into it!

I was hoping to request API exposure for line height and kern features that ImageMagick provides for captions(see docs).

Thanks so much!

API features should be available on the wand.drawing.Drawing class. Drawing.interline_spacing & Drawing.text_kerning property exists. The caption function is just a light-weight wrapper for the caption: protocol. Customizing & extended the text behavior would require you to roll your own drawing context. See Word Wrapping doc as an example.

Hey!

Added an annotation method. This method differs from caption as it requires a wand.drawing.Drawing context to dictate type-face styles. So for kerning, and line height, you would do something like...

message = '   Quick\nbrown\n   fox'
with Image(width=250, height=150, pseudo='xc:lightgreen') as img:
    with Drawing() as ctx:
        ctx.fill_color = 'orange'
        ctx.font_family = 'Times New Roman'
        ctx.font_size = 40
        ctx.text_kerning = -4
        ctx.text_interline_spacing = -20
        img.annotate(message, ctx, left=30, baseline=40)
    img.trim()
    img.save(filename='output.png')
