texture internal format

val set_internal_format : t -> internal_format -> unit

Sets the internal texture format. Implicitly sets the internalFormatMode to USE_USER_DEFINED_FORMAT.

val set_source_format : t -> internal_format -> unit

Sets the external source image format, used as a fallback when no Osg.Image is attached to provide the source image format.
