Brief Description

Custom generator of previews.

Methods

Texture	generate ( Resource from, Vector2 size ) virtual
Texture	generate_from_path ( String path, Vector2 size ) virtual
bool	handles ( String type ) virtual

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

• Texture generate ( Resource from, Vector2 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).

---

• Texture generate_from_path ( String path, Vector2 size ) virtual

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 handles ( String type ) virtual

Returns if your generator supports this resource type.
