MCU.Config.glyphsCachePolicy
Configure copying of pre-rasterized glyph data to RAM for faster access.
Description
Sets the resource cache policy for glyphs.
The following is a list of possible values:
| Value | Result |
|---|---|
"OnStartup" | The data is copied to RAM on startup. Although this enables faster access to data, it might use up limited RAM. |
"NoCaching" | The data is not copied to RAM. Drawing a glyph to the screen from storage may result in reduced performance. |
The MCU.Config.glyphsRuntimeAllocationType property can be used to further configure which memory area is used for copying.
See Text Rendering and Fonts for font engine-specific details.
Note: The property affects both the Spark Monotype and Static font engines.
Usage
This property is accepted in the main application .qmlproject file, or BoardDefaults.qmlprojectconfig for the target platform. It takes a string, and the default value is "OnStartup".
The available options are:
"OnStartup""NoCaching""OnDemand"
Code example:
MCU.Config {
glyphsCachePolicy: "NoCaching"
}Since
This property was introduced in QmlProject API 1.3 .
