Gimp.ThumbnailProcedure.new

function new(plug_in: Gimp.PlugIn, name: String, proc_type: Gimp.PDBProcType, run_func: Gimp.RunThumbnailFunc): Gimp.Procedure {
    // Gjs wrapper for gimp_thumbnail_procedure_new()
}
  

Creates a new thumbnail procedure named name which will call run_func when invoked.

See Gimp.Procedure.new for information about proc_type.

Gimp.ThumbnailProcedure is a Gimp.Procedure subclass that makes it easier to write file thumbnail procedures.

It automatically adds the standard

(Gio.File, size)

arguments and the standard

(Gimp.Image, image-width, image-height, Gimp.ImageType, num-layers)

return value of a thumbnail procedure. It is possible to add additional arguments.

When invoked via Gimp.Procedure.prototype.run, it unpacks these standard arguments and calls run_func which is a Gimp.RunThumbnailFunc. The "args" Gimp.ValueArray of Gimp.RunThumbnailFunc only contains additionally added arguments.

Gimp.RunThumbnailFunc must Gimp.ValueArray.prototype.truncate the returned Gimp.ValueArray to the number of return values it actually uses.
