08-08-2008, 16:29 grhind Joined on 07-03-2008 Posts 46 zones out of order i'm using v15 and basing my code on example VBOcrDemo... when i add a zone to my raster image and then re-recognize and then save results as rtf ie resOptions.Format = RasterDocumentFormatType.Rtf resOptions.FormatLevel = RasterDocumentFormatLevel.Full rdeRasterDocumentEng.SaveResultOptions = resOptions the zones i add manually (after the i've allowed it to find zones on its own) the text in those zones get added to the end of the document instead of the position they are on the page/image itself... what should i be looking for to fix this?    Report

If you want to ensure that they are in a specific order, you will have to create a temporary copy of all your zones, remove the zones from the engine, and then add them back into the engine in the order you prefer.
