How to get the pixel tolerance value?

Hello, 

 

I compare 2 files. My goal is to set a warning message if the pixel tolerance is below a certain value. An error message if it is up to this value.

How can I get the exact pixelTolerance value?

 

Here is my code. I want to update it and put an If condition before the Log.Warning line


     

if (!pic_1.Compare(pic_2, false, 5, false, 5, 0))     
 	{       
 	// Images are differents        
	// Post image differences to the log        
	imgError = pic_1.Difference(pic_2, false, 5, false, 5, 0);        
	Log.Picture(imgMaskError);   
             
	//png file with errors        
	imgError.SaveToFile(sDirectoryPath + sReportName + "_error_p" 
		+ aqConvert.IntToStr(i+1) + ".png");
               
	 // Post a warning message        
	Log.Warning("Pages " + aqConvert.IntToStr(i+1) + " are differents.");            
	aqFile.WriteToTextFile(sDirectoryPath + "log.log", "Page " 	
		+ aqConvert.IntToStr(i+1) + " KO : " + sReportName + "_error_p" 
		+ aqConvert.IntToStr(i+1) + ".png created.\r\n",              
		aqFile.ctANSI, false);     
 	} 

	else      
		{        
		// Pages are equals        
		Log.Message("Pages " + aqConvert.IntToStr(i+1) + " are equals.")        
		aqFile.WriteToTextFile(sDirectoryPath + "log.log",              
			"Page " + aqConvert.IntToStr(i+1) + " OK.\r\n",              
			aqFile.ctANSI, false);      
		}

    I'm not sure of way to get the difference value returned from not matching values, but you specify the tolerance in your compare. 

     

    https://support.smartbear.com/testcomplete/docs/reference/program-objects/picture/compare.html

     

    But for what you're doing I don't think you really even need it. You could just nest compares with varying tolerances.

     

      let maxDifference = 20;
  // check if they're identical
  if(!pic_1.Compare(pic_2)) {
    // if they're more than maxDifference log error
    if(!pic_1.Compare(pic_2, false, maxDifference, false, 5, 0)) {
      Log.Error()
    } else {
      // they're different but acceptable log a warning
      Log.Warning();
    }
  }
