    Thanks for your response.

    With the help of Test Complete support team figured out that I need to use high quality image format. I was using .jpg format. I created new images with ".png" format, now image comarison excludes areas with Transparent color and shows images are equal.

It would be interesting to see your two images and the command you're using for the comparison.

Hi,

My script looks like this, I have many screenshots to compare, so I have For loop to get all Test images from C: drive and Base images are stored in Regions.

 

ObjTestPict = Utils["Picture"];

FolderPath = "C:\\Users\\...";
ObjFolder = aqFileSystem["GetFolderInfo"](FolderPath);
AllTestFiles = ObjFolder["Files"];
TestFileCount = AllTestFiles["Count"];
for(i=0; i<TestFileCount; i++)
{
       TestPict = AllTestFiles["Item"](i);

 

       BasePict = Regions["GetPicture"](BasePictName);  

       ObjTestPict["LoadFromFile"](TestPict["Path"]);

 

       if (! Regions["Compare"](BasePict, ObjTestPict, true)) // compare screenshots
      {
           Log["Message"]("Pictures are not identical");
      }

}

 

Thanks,

Samixa

    If I compare images without editing baseline with Transparent color, it only shows two difference.

     

    Don't know if you've resolved this, but perhaps the transparent pixel (0, 0) is not actually what you think it is...
