1. You created two images, from "xc:" and "label:". As you didn't specify a height, IM used "500x1" for the "xc:" image. Is that an issue?

2. I've never understood what "-direction right-to-left" does or is supposed to do. Sorry.

Thanks snibgo. Careless mistake. I was thinking -background but wrote xc:. I will update my post.

Direction is utilized for complex text layout @ https://en.wikipedia.org/wiki/Complex_text_layout. The RAQM delegate library is required. Otherwise direction is ignored.

Thanks for the update. Can you add that to the comments for -direction on the options page?
