Member Function Description

• Texture generate ( Resource from ) virtual

Generate a preview from a given resource. This must be always implemented.

Returning an empty texture is an OK way to fail and let another generator take care.

Care must be taken because this function is always called from a thread (not the main thread).

• Texture generate_from_path ( String path ) virtual

Generate a preview directly from a path, implementing this is optional, as default code will load and call generate()

Returning an empty texture is an OK way to fail and let another generator take care.

Care must be taken because this function is always called from a thread (not the main thread).

• bool handles ( String type ) virtual

Return if your generator supports this resource type.
