You can get around this problem by creating your glyphs directly in the app using only quadratic control points. The app will convert your cubic splines to quadratic paths but the conversion is not lossless and the converted paths will contain more points than the original path. Most SVG editors uses the cubic form but TrueType outlines can only contain quadratic control points.

There is a mathematical difference between quadratic and cubic Beziér curves. It is recommended that you convert your path to simple outlines, without strokes before you import them to the app. The fastest way to get your drawings from Illustrator or Inkscape into BirdFont is the copy and paste commands but you can also save your work as SVG files and import them into the app. Click on a point and press shift to move the point independent of its handle. Hold down the space key and click to move the canvas. Press w to toggle between smooth node and corner node. Click on a handle and hold down the shift key if you want to keep the angle of a handle while you are changing the length of the handle. Delete points with the delete or backspace keys (break the path with shift + delete). You can add the points to the path by double clicking in the path. The margin guides are red.Īdjust the position of all control points and handles. You can change the line height by adjusting the top and bottom margin guides. The HTML preview file contains examples of how you select which alternate that should be displayed when the font is used on the web. You can get around this problem by creating an empty fallback glyph and importing a monochrome version with less details of your colored letters.Īlternates provide a way to put several glyphs on the same Unicode character and selecting which glyph that should be displayed when the font is used. In addition will glyphs with too many details hardly fit on the TTF grid. Creating monochrome fallback glyphs can take a long time if your glyphs contains many small parts (hundreds or even thousands). Mozilla Firefox and Microsoft Edge has support color fonts in their browsers but Chrome lags behind at this point. OpenType-SVG color fonts is a rather new format and some applications does not support it.
