Might be a case of not-obvious error message. Are you sure that selector exists? Notably the first path, dev
vs div
?
:man_facepalming: OMG.... so it works, but still need to scroll to that section...
similar result with
browser.screenshot(path: "xe-test-2.jpg", selector: "div section div div main > div")
browser.screenshot(path: "xe-test-2.jpg", selector: "div section div div main:nth-child(2) > div:nth-child(2) > div:nth-child(2)")
selector appears correct but bottom is all blank
I think we could try to pass area arguments right to the method which now is not supported but can be

That would be cool @route
The Page.captureScreenshot
command has a clip
parameter, it could be passed from options
.
@alexeyr-ci we just need to find either time for me or someone who can implement it ;)
I'd make a PR, but I ended up just calling Page.captureScreenshot
directly as a workaround :) I still might end up doing that. Also I missed that you meant that already in

As a fix for
selector appears correct but bottom is all blank
which I also ran into I think you just need to intersect the bounding rectangle in area_options
with the viewport (when full
is false).
I think this was fixed in https://github.com/rubycdp/ferrum/pull/410
Close?
Yes, looks like it.
I wish to be able to use ferrum to load a webpage and take a screenshot of a specific screen portion.
it should be delimited by x,y,w,h or css selector.
I tried....
none works.
