[Extent 3.0.1] base64 string image won't display on lightbox

[egeaksoz-zz]

Hi @anshooarora,

I was able to create a base64string image on report with the following code:

String base64Screenshot = "data:image/png;base64,"+ ((TakesScreenshot)driver.getScreenshotAs(OutputType.BASE64);
test.log(Status.FAIL, "Test Failed", test.addScreenCapture(base64Screenshot));

Though it shows the screenshot on test report, lightbox won't work and displays blank page.

Base64 images are currently not supported in this version due to issues they have caused on the previous versions and ExtentX. Due to the amount of space they take (these can be extremely long strings) - they blow up the size of the HTML file and also slow down queries in ExtentX.

There have been similar requests earlier but I do not plan to add this feature in version 3 due to the above. Or, maybe I will add it and not support issues that arise out of it. I am leaning more towards the latter, will update this thread soon with my decision.

We might have to look this problem in a different way. The addBase64Screenshot should be changed to take the base64 string and compress using gzip technique. Then in the report, we should use some javascript to unzip the compressed base64 string. This would help in reducing the size of the file and the data sent to the database.

I have experienced same issues earlier ( Size of screenshots and not able to add the images inline in the latest 3.x versions.
Below is the solution:

1. Reducing the size of the screenshots
   I have searched the web and with the help of some Java blogs, came up with an idea of resizing the screenshot. So credit goes to the guys who posted the help in the blogs. I don't exactly remember the links.
2. Adding screenshots inline.

Reducing the size of the screenshots:

• Create a function that will do the resizing and call it. See below:

public void processPicture(String inputFilePath, String outputFilePath, int interpolationMethod, double sigmaFactor) {

	double scaleFactor = 0.1;

	Opener opener = new Opener();

    ImageProcessor ip = opener.openImage(inputFile).getProcessor();
    

 //  for medium sized screenshot use scaleFactor 0.15.
    scaleFactor = 0.2;
    	
ip.blurGaussian(sigmaFactor / scaleFactor);
ip.setInterpolationMethod(interpolationMethod);
ImageProcessor outputProcessor = ip.resize((int)(ip.getWidth() * scaleFactor), (int)(ip.getHeight()*scaleFactor));
IJ.saveAs(new ImagePlus("", outputProcessor), outputFilePath.substring(outputFilePath.lastIndexOf('.')+1), outputFilePath);
    }

}`

Now call the function:
processPicture(imageFile, imageFile_resized, ImageProcessor.NONE, 0.3);

Result: In my case, for a mobile screenshot , the original size may be around 1MB or more. With the processing as given above the size of the screenshot comes down to very very less size of around 10 to 30KB only.

Adding inline screenshot images in Extent 3.0
Add the below string in your log statements. It will add the required image file under the log statement in your extent html logs.

<ul class='screenshots'>
<li>
<img data-featherlight= imageFilePath width='20%' src='' data-src=' imageFilePath'>
</li>
</ul>

Hope that helps.

Thank you guys for your answers. I switched back to v2.4. But @SrinivasTangella I will try it and tell if it works or not.

@savatagean

By the by, I have forgot to mention that while capturing the screenshot do it as below:
OutputType.FILE, but not OutputType.BASE64

File scrFile = ((TakesScreenshot) getDriver()).getScreenshotAs(OutputType.FILE);

It should work. Because I had similar issue and the fix I have mentioned is what I have currently implemented and working.

Hi Anshoo. Any update on Base64 image support for version 3.x? I email the reports out to clients who don't have shared folder access, and this is the only way I know to give them screenshots in the report.

Hi @anshooarora,
Is there have any update on Base64 image in ExtentReport 3.0.5 and higher?
Now, I'm unable to send the email report with to my client because the attach screenshot does not add into it, so fails to view in the client view :(.
Could you provide me a solution for this issue?
Thanks!
