when taking screenshots with a mac, the images are incorrect #52
Comments
I have confirmed that this is related to the retina display only. If I use (only) an external display on a Macbook pro, screenshots come out the same as they do on any other platform. |
@psbanka thank you so much for your kind words! Selenium seems to create a way bigger image on retina displays than on normal screens. I had similar problems when working on mobile support (iPhone/iPad). Still haven't figured out what's the best way to tackle that problem. I probably need to resize the image down to the actual document size but then I loose valuable information of the screenshot. Other way would be to scale up the element boundaries. Both ways need to get tested and evaluated. |
Does window.devicePixelRatio help? Figuring out the size and location of an element by scaling up like this: |
Having the same issue. The generated screenshot has the correct size, but all dom elements are twice as big. |

We're having this problem in our team too. Older mac screenshots do not compare successfully to newer (retina) macs |

Also having this issue :) |

Someone should really try experimenting by scaling the crop rectangle by |
I was trying to scale up element size to retina size but screens unfortunately still are cut. |
@TheSavior Yes, scaling by window.devicePixelRatio now works just fine as the screens are no longer cut since #116. Thanks for the advice! |
Has there been any movement on this in the meantime? |
@TheSavior thanks , I find out the solution from your tip. |
Thanks for all your work on this library. I love
webdrivercss
! In fact, I am working on an effort to replace all ourphantomcss
tests with webdrivercss. In addition, I am planning to give a talk to our local JavaScript meetup about this great project!One oddity I am finding is that if I run
webdriverio
withwebdrivercss
on our (Linux-based) continuous-integration system, the screen-capture works flawlessly. However, if I run the same suite of tests on a mac (with a retina display), I find that the images produced bywebdrivercss
are the correct size but are oddly scaled and inappropriate. (FWIW, I have often found that other screen-capture with a retina display can produce similar oddly-scaled images for other applications).Is there a work-around for this problem? I'd be happy to provide a pull-request if you might point me toward where in the code the issue might lay?
Thanks!
