# PsdProcessor.StringCallback Property 
 
Gets or sets the callback function that processes text layers. The function should accept an alias for the calling object and a [PsdTextFrame](https://www.graphicsmill.com/docs/gm/T_Aurigma_GraphicsMill_Codecs_Psd_PsdTextFrame.htm.md) and return a String. It is convenient to use lambda expressions as demonstrated below.
