I have a font in ttf file and want to generate SVG with text turned into paths. I don't need image (so using imagettftext or Image Magick font rendering capabilities is not enough), I need shape, that can be scaled up and down and I want to lose information about font used and don't want to reference it in SVG file (so font-face declarations can't be used here). Is it possible?
To create text SVG's in Inkscape you need to turn your text into a path. To do this just select your text and then go to “path” in the top menu bar and then choose “object to path”. This will turn your text into a path. From here you can click into each individual letter of your text and edit however you'd like.
When you convert text to a path, the text becomes a graphic object that cannot be altered. Still, Inkscape lets you change the converted text's look by reshaping it. This type of conversion assists in making wordmarks or logos.
I have created my own class to process SVG font file and to turn text into glyphs. Example of using:
include "SVGFont.php"; $svgFont = new SVGFont(); $svgFont->load("/path/to/font.svg"); $result = $svgFont->textToPaths("Simple text", 20);
Example result:

A workaround is using inkscape (execute it via exec
or so after saving the SVG document to file.svg
). In inkscape 0.49+, you can simply pass --export-to-svg
and --export-text-to-path
, like this:
$ inkscape file_text.svg --export-text-to-path --export-plain-svg file_shapes.svg
In inkscape < 0.49, you can manually script inkscape (note that this requires an X server):
$ inkscape --with-gui --verb EditSelectAll --verb ObjectToPath --verb FileSave \ --verb FileQuit file.svg
