Shifting existing drawing to center #227

Closed kilacoda closed 2 years ago

kilacoda commented 2 years ago

Hi,

I have a figure like this, which is created by simply using poly in a loop: 1

I'd like to center the image produced at some coordinate of the polygons in that blob and scale the image a bit larger for more clarity (my ultimate goal is to export this SVG to a PNG and make a GIF out of multiple such images). Is there any way I can do this? I tried origin(<point>) but that seems to set the origin with which all new figures are drawn to be set to (0,0).

Hi. I suppose the way Luxor/Cairo does the drawing can be awkward for some workflows like this - it's more of a "paint on the canvas and move on" approach, rather than "build objects in memory and then render them" approach.

I've had some success with stored paths - you build a path on the drawing then store it in a variable rather than actually draw it immediately. Also, if you have a list of points you can transform them using polymove!, polyscale! et al. These sometimes can overcome the basic Cairo drawing model.
