Adding a call to SetInputName("") in my setup routine seemed to work!But may I ask *why* that worked? I'd assume that everything should be handled in tesseract::Init() - is there other functionality that Init doesn't take care of? Thanks! (Also, I'm using XCode over here - easiest way to get started with OF) On Mar 21, 5:28 am, Renard Wellnitz <[email protected]> wrote: > Hi, > > you can try to call SetInputName() before calling GetHOCRText(). > > Are you using eclipse CDT?
