Answers: inkscape - Converting large SVG to PNG file

user209128

So I have a 16mb SVG file with about 30,000 nodes and I've been trying to convert it to a 10,000x10,000 png image. I tried a lot of stuff and the closest I got was with inkscape, but it got some weird error halfway through the command and only rendered half the image. Does anyone know the best way to do this?

Imagemagick is a dedicated command line tool for converting and manipulating images, so may product better results:

convert -density 1200 -resize 10000x10000 your.svg your.png

You may need to change the density command to get optimal results

import - Inkscape: what are "line" objects?

import svg inkscape

Peter Mortensen

What is a "line" object in Inkscape? Drawing lines in Inkscape is by using the tool "Draw Bezier curves and straight lines (Shift+F6)". This creates objects of another type, "path".

Using Inkscape: is there a way to convert an object of type "line" into an object of the more general type "path"?

I have imported a drawing (mostly lines, rectangles and text) that has been through Adobe Illustrator: originally made in Inkscape, imported into Illustrator, edited, saved from Illustrator as SVG, imported into Inkscape.

Sample from the imported SVG file:

<path
   id="path5855"
   stroke="#000000"
   d="  M320.198,275.935" />

<line
   fill="none"
   stroke="#000000"
   x1="348.553"
   y1="45.097"
   x2="348.553"
   y2="185.346"
   id="line3368" />

Update 1: I have inspected the original XML (SVG) file from 2006 and it does not contain any "line" XML tags. Thus it must be a crime of Adobe Illustrator.

When a line is selected in this imported SVG file the bottom panel displays: "Line in root. Click selection to toggle scale/rotation handles.".

When a line is selected that was drawn in Inkscape the bottom panel displays: "Path (2 nodes) in Layer 1. Click selection to toggle scale/rotation handles."

What is the difference between "line" and "path"?

Is "line" some kind of read-only/non-editable object?

A generic term like "line" is not easy to use in search, but I have now found the definitions for "line" and "path":

SVG line: http://www.w3schools.com/svg/svg_line.asp

SVG path: http://www.w3schools.com/svg/svg_path.asp

Platform: Inkscape v0.46 (2008-03-10), Windows XP 64 bit, 8 GB RAM.

A line is just what it says, a straight line. A path is more versatile and can represent almost any curve.

You can always convert a line into a path, but not vice versa in the general case. In Inkscape use the menu item Path/Object to Path or the keyboard shortcut Shift+Ctrl+C.

You can't edit nodes on line objects because a line object has just start and endpoint, but no nodes.

As a path can also be a straight line Inkscape doesn't bother to create line elements. It always creates path elements. If your SVG file contains line elements Inkscape can read them and you can manipulate them.

Inkscape is built around SVG:

http://www.w3.org/TR/SVG11/

(although Inkscape supports more effects and probably more features than most browsers, IIRC, YMMV)

Wikipedia's SVG entry says that although a Path is very general (and I remember from experience can represent line(s) as well as splines), there are Line objects as a basic shapes.

Perhaps you can load the .svg file in a text editor (if you are so inclined) and inspect the SVG xml code to determine how it is representing the data.
