"Images dimensions mismatch" error in full page screenshot comparison

[jpratt2]

I would like to be able to use the equalsWithDiff function when using a full-page screenshot.
Currently I git this error:
"Images dimensions mismatch: image1 - 1548x3284; image2 - 1548x3291"

The difference is 7 pixels in height. I am using Chrome.

My code:

 BufferedImage expectedImage = null;
        try {
            expectedImage = ImageIO.read(new File("C:\\2020_06_12_13_25_31_832.png"));
        } catch (IOException e) {
            e.printStackTrace();
        }
Shutterbug.shootPage(driver,ScrollStrategy.WHOLE_PAGE).equalsWithDiff(expectedImage,"screenshots2");

Hi @jpratt2 ,

Were screenshots taken on different systems/PCs? That may happen if you taking baseline screenshot on windows and run your comparison on e.g. headless linux

I can no longer duplicate this issue. Please disregard this.

[jpratt2]

Actually, I think I fixed it by adding a 3-second delay for the page to finish loading

Glib, I would like to re-open this.
Which is better, to still create a diff image with the difference in height highlighted in red, or to throw an error?

I am still getting this error from time to time, and I am investigating the cause. Meanwhile, wouldn't it be best to still make a diffimage?

And for the record, I found the culprit: some pages had an a/b test. And some pages had slight variances due to IP localization; it mattered if I connected via VPN.

Hi
I'm also facing the same issue @jpratt2 how you resolve this? Im using the same machine to generate the baseline and actual screenshot.

[jpratt2]

@Chankami -- actually I didn't solve it.

Glib, I am getting this error on pages that are not affected by the reasons I stated earlier. Could it be a RAM limitation? I am using my machine simultaneously, and I don't know what else it could be.
I can't duplicate it predictably, but in this example, we see that image 1 (the image diff) is slightly longer than the original, 2215px vs 2192px.

Hi @jpratt2 , at the moment its pixel by pixel comparison only. I'll have a look at possible reasons why the size differs.

Hi
Has anyone found a solution for the size mismatch? I'm getting the same error message when capturing full-sized screenshots (both screenshots were taken on the same machine).

Can some one please help me to blur certain portion of text on UI.
Per example First Name I would need to blur only "Name"

Any help please.
