- cowpatch.svg_utils.gg_to_svg(gg, width, height, dpi, limitsize=True, eps=0.01, maxIter=20, min_size_px=10)[source]
Convert plotnine ggplot figure to svg and return it (with close to perfect sizing).
- Parameters
gg (plotnine.ggplot.ggplot) – object to save as a png image
width (float) – width in inches to be passed to the plotnine’s ggplot.save function
height (float) – height in inches to be passed to the plotnine’s ggplot.save function
dpi (int) – dots per inch, to be passed to the plotnine’s ggplot.save function
limitsize (boolean) – logic if plotnine’s ggplot.save function should check if the requested width and height in inches are greater than 50 (assumes the user accidentally entered in these values w.r.t. pixels)
eps (float) – maximum allowed difference between height and width output versus the desired output
maxIter (int) – maximum number of steps that can be used to the difference between desired and output height and width within minimum distance
min_size_px (int) – early stopping rule if converging height or width has a pixel size smaller than or equal to this value (assumes process will not converge)
- Returns
(aka an svg representation)
- Return type
svgutils.tranform representation of the ggplot object
Notes
Code idea motified by the stackoverflow question here, https://stackoverflow.com/questions/8598673/how-to-save-a-pylab-figure-into-in-memory-file-which-can-be-read-into-pil-image/8598881 and truly influenced by svgutils.transform.from_mpl function.
