I've been doing experiments at displaying static text images in the mode-line using Imagemagick to generate the image (see below). I would like now to generate such an image in a dynamic way, providing information from within Emacs. For example, I could display the current major mode or the cursor line/column (might be slow).

My question is how to dynamically generate the image according to the provided information (e.g. how to call and pass arguments to Imagemagick). Displaying line/column using image Imagemagick might very slow but still, I would like to try.

Multilines mode-line with static text image (through imagemagick)

Imagemagick command used for the screenshot:

convert -antialias -background none -fill white -family Roboto -weight regular -gravity southeast -size 64x42 -pointsize 20 label:"Emacs\nv26.3" label.png

And in the modeline (header line in my case):

(propertize " " 'display (create-image "~/label.png" 'png nil :ascent 90 ))

  • You can look into nyan-cat for inspiration. Bsically, add an eval form into mode-line-format. – Yuan Fu Jun 3 '20 at 1:45
