[ctb] | Title: | Render SVG Images into PDF, PNG, (Encapsulated) PostScript, or Bitmap Arrays |
|---|---|
| Description: | Renders vector-based svg images into high-quality custom-size bitmap arrays using 'librsvg2'. The resulting bitmap can be written to e.g. png, jpeg or webp format. In addition, the package can convert images directly to various formats such as pdf or postscript. |

Render svg image into a high quality bitmap. When both width and height
are NULL, the output resolution matches that of the input. When either width
or height is specified, the image is scaled proportionally. When both width
and height are specified, the image is stretched into the requested size.
