getSettingEnumOptions(keypath: T): string[]

getSettingEnumOptions(keypath: `ubq://${T}`): string[]

findAllSettings()#

Returns a list of all the settings available.

Returns#

string[]

A list of settings keypaths.

Signature#

findAllSettings(): string[]

getSettingType()#

Returns the type of a setting.

Parameters#

Parameter	Type	Description
`keypath`	`string`	The settings keypath, e.g. `doubleClickSelectionMode`.

Returns#

SettingType

The setting type.

Signature#

getSettingType(keypath: string): SettingType

setURIResolver()#

Sets a custom URI resolver.

This function can be called more than once. Subsequent calls will overwrite previous calls. To remove a previously set resolver, pass the value null. The given function must return an absolute path with a scheme and cannot be asynchronous. The input is allowed to be invalid URI, e.g., due to placeholders.

// Replace all .jpg files with the IMG.LY logo
engine.editor.setURIResolver((uri) => {
  if (uri.endsWith('.jpg')) {
    return 'https://img.ly/static/ubq_samples/imgly_logo.jpg';
  }
  // Make use of the default URI resolution behavior.
  return engine.editor.defaultURIResolver(uri);
});

Parameters#

Parameter	Type	Description
`resolver`	(`URI`, `defaultURIResolver`) => `string`	Custom resolution function. The resolution function should not reference variables outside of its scope. It receives the default URI resolver as its second argument

Returns#

void

Signature#

setURIResolver(resolver: (URI: string, defaultURIResolver: (URI: string) => string) => string): void

defaultURIResolver()#

This is the default implementation for the URI resolver.

It resolves the given path relative to the basePath setting.

engine.editor.defaultURIResolver(uri);

Parameters#

Parameter	Type	Description
`relativePath`	`string`	The relative path that should be resolved.

Returns#

string

The resolved absolute URI.

Signature#

defaultURIResolver(relativePath: string): string

getAbsoluteURI()#

Resolves the given path.

If a custom resolver has been set with setURIResolver, it invokes it with the given path. Else, it resolves it as relative to the basePath setting. This performs NO validation of whether a file exists at the specified location.

Parameters#

Parameter	Type	Description
`relativePath`	`string`	A relative path string

Returns#

string

The resolved absolute uri or an error if an invalid path was given.

Signature#

getAbsoluteURI(relativePath: string): string

System Information#

Access memory usage, export limits, and system capabilities.

getAvailableMemory()#

Get the currently available memory.

Returns#

number

The available memory in bytes.

Signature#

getAvailableMemory(): number

getUsedMemory()#

Get the engine’s current memory usage.

Returns#

number

getMaxExportSize()#

Get the maximum export size limit for the current device.

Exports are only possible when both width and height are below this limit. Note that exports may still fail due to other constraints like memory.

Returns#

number

The upper export size limit in pixels, or maximum 32-bit integer if unlimited.

Signature#

getMaxExportSize(): number
