Word wrapping Drawing.text

[wodim]

I'm not sure this is the appropriate place to ask for this. I'd call it a feature request but I'm going to ask it as a question, because I'm not sure if it actually can be done using Wand as it is now (i.e. I'm missing something). I think ImageMagick can do it itself.

I want to word wrap text to a certain width in pixels with wand.drawing.Drawing.text wand.image.BaseImage.caption is (I think) unsuitable for my needs, as I need the text to have a stroke. By now I'm using textwrap.fill from the standard library as a workaround but, as you can imagine, it's not a perfect solution.

draw = Drawing()
draw.font_size = 100
draw.fill_color = Color('#fff')
draw.stroke_color = Color('#000')
draw.stroke_width = 2
draw.gravity = 'south'
draw.text(0, 0, textwrap.fill(text, 20))
draw(img)

Thanks for Wand by the way, great work.

Any idea of how to do this using draw.text method instead of using caption method ?
@wodim : did you find any other solution ?

I've run into this issue today. ImageMagick can definitely do it itself.

I might have a look into adding this if I get the time.

I've just submitted a pull request (#375) to allow a stroke on wand.image.BaseImage.caption.

Following up on this. Currently the drawing class will remain very low-level API. However word-wrapping is often requested. I'm hesitant at attempting & shipping a word-wrap solution as users will often have conflicting behavior requirements (e.g. locale grammar, text/alignment tracking, hyphenation rules/exceptions).

Perhaps, one day, we'll introduce a wand.contrib module that'll hold community driven solutions to common problems; but until then, I've updated the docs to include an example of how one may achieve word-wrapping.
