Text

open class Text : UIResourceElement

A text ui element to display text on the glasses screen

Each font is defined by a font slot Text length (in bytes!) is limited to the communication channel mtu-10 bytes

2 types of fonts can be used:

Stock fonts that comes pre-installed with the glasses
Custom font slots that can be created, added to the application resources and uploaded to the glasses

Custom fonts creation is in beta and documented separately Max size 32KB All custom slots are persistent, meaning uploaded fonts for those slots are kept saved on the glasses between reboots

NOTE: The behaviour of adding 2 (or more) different custom fonts with the same slot to the same screen is undefined

Supported transformations: Translate
