Inherits: Reference < Object

Custom generator of previews.

Description

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

Method Descriptions

  • bool can_generate_small_preview ( ) virtual

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

By default, it returns false.


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).


Generate a preview directly from a path with the specified size. 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 generate_small_preview_automatically ( ) virtual

If this function returns true, the generator will automatically generate the small previews from the normal preview texture generated by the methods generate or generate_from_path.

By default, it returns false.


Returns true if your generator supports the resource of type type.
