From App Bundle
PhotoEditor SDK supports adding custom fonts from the app bundle. In this example, we add the font Raleway.
Creating Font
objects#
Font
objects#We create a URL pointing to the font's location in the app bundle and pass it to the Font
constructor.
A Font
object is a simple collection of the metadata of a font, the fontName
, the displayName
and the url
for non system fonts.
We can also create another system font using only the fontName
.
Add fonts to asset catalog#
In order to add the new fonts to our asset catalog, we first add the default items and then append our fonts to the fonts
array.
