setAutomaticFontSizeAdjustment

@NonNull
public GeckoRuntimeSettings setAutomaticFontSizeAdjustment(boolean enabled)

Set whether or not font sizes in web content should be automatically scaled according to the device's current system font scale setting. Enabling this will prevent modification of the font size factor. Disabling this setting will restore the previously used value for the font size factor.

Parameters:

Returns:

This GeckoRuntimeSettings instance.

getAutomaticFontSizeAdjustment

public boolean getAutomaticFontSizeAdjustment()

Returns:

True if font sizes are automatically adjusted.

setFontSizeFactor

@NonNull
public GeckoRuntimeSettings setFontSizeFactor(float fontSizeFactor)

Set a font size factor that will operate as a global text zoom. All font sizes will be multiplied by this factor.

The default factor is 1.0.

Currently, any changes only take effect after a reload of the session.

This setting cannot be modified while automatic font size adjustment is enabled.

Parameters:

fontSizeFactor - The factor to be used for scaling all text. Setting a value of 0 disables both this feature and font inflation.

Returns:

This GeckoRuntimeSettings instance.

getFontSizeFactor

setFontInflationEnabled

@NonNull
public GeckoRuntimeSettings setFontInflationEnabled(boolean enabled)

Set whether or not font inflation for non mobile-friendly pages should be enabled. The default value of this setting is false.

When enabled, font sizes will be increased on all pages that are lacking a <meta> viewport tag and have been loaded in a session using GeckoSessionSettings.VIEWPORT_MODE_MOBILE. To improve readability, the font inflation logic will attempt to increase font sizes for the main text content of the page only.

The magnitude of font inflation applied depends on the font size factor currently in use.

Currently, any changes only take effect after a reload of the session.

Parameters:

enabled - A flag determining whether or not font inflation should be enabled.

Returns:

This GeckoRuntimeSettings instance.

getFontInflationEnabled

public boolean getFontInflationEnabled()

Get whether or not font inflation for non mobile-friendly pages is currently enabled.
