Resource API

Font

dmn.font.load()

Opens the system file picker, imports a font, and returns its app-managed path.

const result = await dmn.font.load();
// {
//   success: boolean,
//   error?: string,
//   errorCode?: 'invalid-font-content',
//   fontName?: string,
//   fontPath?: string,
//   weightRanges?: Array<{ min: number, max: number }>
// }

fontName is the family name read from the font file’s own metadata (the file name is used only when the font has no readable family record), so several files of one family import as one family. If the file cannot be parsed as a font, success is false, errorCode is 'invalid-font-content', and nothing is copied. When success is false and errorCode is absent, the user cancelled the picker.

Image

dmn.image.load()

Opens the system file picker, imports an image, and returns its app-managed path.

const result = await dmn.image.load();
// {
//   success: boolean,
//   error?: string,
//   errorCode?: 'invalid-image-content',
//   imagePath?: string
// }

The file is validated by its content, not its extension. A file that cannot be decoded as an image returns success: false with errorCode: 'invalid-image-content'; a cancelled picker returns success: false with no errorCode.

Sound

See the dedicated Sound API reference for sound library visibility, editing, and compatibility APIs.

Paths returned by resource APIs must be treated as opaque app-managed identifiers.
