Gravity (for pango) in Magick++

Post by olear »

Hi, been using Pango Markup for a while, works great, but I need some form of text align, I see in the code for pango.c (https://github.com/ImageMagick/ImageMag ... ngo.c#L304) that you take align info from DrawInfo, but I can't find any option in Magick++ to set this.

What are my options for align and gravity using Pango?

Using convert I can just do: convert -gravity Center pango:"whatever", how can I reproduce gravity before read in Magick++?

At this moment you cannot do that in Magick++. We will have to figure out how we want to make this available in Magick++. I will get back to this topic when we have decided how to do this.

Thanks for the info.

EDIT: a pango align define would be good enough for me.
