# Tools for making OpenType-SVG fonts

- **addsvg** adds an SVG table to a font, using SVG files provided. The font's format can be either OpenType or TrueType.

- **dumpsvg** saves the contents of a font's SVG table as individual SVG files. The font's format can be either OpenType, TrueType, WOFF, or WOFF2.

- **fonts2svg** generates a set of SVG glyph files from one or more fonts and hex colors for each of them. The fonts' format can be either OpenType, TrueType, WOFF, or WOFF2.


### Dependencies

- Python 3.6 or higher

- [FontTools](https://github.com/fonttools/fonttools) 3.1.0 or higher


### Installation instructions

- Make sure you have Python 3.6 (or higher) installed:

		python --version


- Setup a virtual environment:

		python -m venv ot-svg


- Activate the environment:

		source ot-svg/bin/activate


- Update **pip**:

		pip install -U pip


- Install **opentypesvg**:

		pip install opentypesvg


# How to make OpenType-SVG fonts?

### Step 1
#### Generate a set of SVG files from a series of fonts and color values.

![step1](https://raw.githubusercontent.com/adobe-type-tools/opentype-svg/master/imgs/step1.png "step 1")

	fonts2svg -c 99ccff,ff0066,cc0066 fonts/Zebrawood-Shadow.otf fonts/Zebrawood-Fill.otf fonts/Zebrawood-Dots.otf

### Step 2
#### Add a set of SVG files to an existing OpenType (or TrueType) font.

![step2](https://raw.githubusercontent.com/adobe-type-tools/opentype-svg/master/imgs/step2.png "step 2")

	addsvg fonts/SVGs fonts/Zebrawood.otf

You can use **Step 2** without doing **Step 1**, but there are a few things you need to be aware of when using the **addsvg** tool:

* After the SVG files are saved with the authoring application (e.g. Adobe Illustrator, CorelDRAW!, Inkscape) they should be put thru a process that optimizes and cleans up the SVG code; this will slim down the file size while keeping the resulting artwork the same. For this step you can use one of these tools:
	* [SVG Cleaner](https://github.com/RazrFalcon/svgcleaner-gui/releases) (GUI version)
	* [SVG Cleaner](https://github.com/RazrFalcon/svgcleaner) (command line version)
	* [SVG Optimizer](https://github.com/svg/svgo)
	* [Scour](https://github.com/scour-project/scour)
	* [picosvg](https://github.com/googlefonts/picosvg)

* **addsvg** requires the SVG files to be named according to the glyphs which they are meant to be associated with. For example, if the glyph in the font is named **ampersand**, the SVG file must be named `ampersand.svg`.

* **addsvg** expects the color artwork to have been designed at the same size as the glyphs in the font, usually 1000 or 2048 UPM. This means 1 point (pt) in the authoring app equals 1 unit in font coordinates. If the artwork's canvas size is not the same as the font's UPM value, use the `-k` option to prevent the tool from removing the SVG's `viewBox` parameter. Retaining the `viewBox` parameter will enable the artwork to be scaled to the full extent of the viewport (i.e. the font's UPM).

* If the artwork's `<svg>` element contains `height` and/or `width` parameters, remove them, otherwise the artwork will have a fixed size and won't be allowed to scale to the full extent of the viewport.
