R help - Feb 2019 - magick package says format is PNG when we load an SVG.

Dear All,

Here is a MWE :

library(magick)
tiger <- image_read_svg('http://jeroen.github.io/images/tiger.svg',
width = 400)
print(tiger)

##   format width height colorspace matte filesize density
## 1    PNG   400    400       sRGB  TRUE        0   72x72

Why does the format say PNG ? Should it not say SVG? We just read an SVG file.

Can someone please explain?

Best Regards,

Ashim

The image format in magick is raster based, not vector based, no? So I'd
expect that image_read_svg() converts the file on the fly.

Dear Peter,

So when I convert from PDF to SVG it will first convert to raster and then
back to vector ? Is'nt there a way of preventing this ?

Many thanks,
Ashim
