EditorResourcePreviewGenerator

    Custom generator of previews.

    Custom code to generate previews. Please check in to find out the right size to do previews at.

    • bool can_generate_small_preview ( ) virtual

    If this function returns true, the generator will call or generate_from_path for small previews as well.

    • generate ( Resource from, size ) virtual

    Generate a preview from a given resource with the specified size. This must always be 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).
