CitrixParseTextFuzzy Function

Action

This function performs optical character recognition (OCR) on a selected screen region and stores the result in a sResult parameter. Screen regions can be specified absolutely or relative to a window (by specifying a window handle).

注: OCR operations are only possible in Normal Mode (see CitrixInit). This function fails when used in Fast Mode. When the optional font parameters are present, the pattern file is checked for the used font’s availability. When the parameters are omitted font checking is not performed.

CitrixParseTextFuzzy performs OCR more exactly than CitrixParseText but requires more resources.

Example

  transaction TMain
  var
    sParam1 : string;
  begin
    CitrixInit(640, 480); // do not change the resolution
    CitrixConnect("lab1", "user", "password", "domain", COLOR_16bit);
    CitrixWaitForLogon();
    CitrixParseTextFuzzy(sParam1, DESKTOP, 73, 109, 74, 23, "eng"); 
    Print("sParam1: " + sParam1);
    CitrixDisconnect();
  end TMain;
