![]() Īssuming I wanted to save the webpage as an image rather than as an. Of course, I could also avoid that problem by working from the original webpage, with each video paused at a frame that would convey a sense of its contents. To correct that, a perfectionist might have to edit the final image, to insert a recognizable image from the relevant video. This method might unfortunately save a playing video as a vague blur. Note that, when saved in the “Web Page, complete” format, there would be a similarly named folder, containing material relevant to the saved. In Firefox, saving the webpage as a file would mean using the menu: File > Save Page As > enter filename > Save as Type: Web Page, complete. I could just reopen the saved webpage file. That way, it would not be necessary to start over with preparations, from the beginning, if for some reason the webpage changed, or if the tab or the browser was inadvertently closed during the process. It probably made sense to make a file copy of the webpage, just in case, even if I did plan to work from the original. Once the page was prepared, I could save it as a file. Working from a copy of the webpage, rather than the original, would have the advantage of preserving these potentially time-consuming preparations. Or if I was capturing something like a Facebook wall, where the user may have to click a link in order to see “more comments” following an entry, I would prepare by clicking all those links, so that everything I wanted to include was visible. Next), I would prepare by using a browser add-on (e.g., AutoPagerize) to display all those pages in one: it would keep unrolling the webpage as long as I kept scrolling down. For instance, if I was capturing a webpage that was broken up into separate pages (with e.g., a set of links at the bottom, allowing the user to choose from pages 1, 2, 3. To do that, I would first prepare the webpage as desired. This preparation could involve pre-scrolling or other steps. ( Another post tackles a similar problem, involving a horizontal rather than vertical concatenation.)Įventually, in the case of an attempt to capture a long Facebook page, either Facebook changed or I got smarter, but for whatever reason it became possible to pause each playing video, and it would then not insist on continuing to play, so the captures worked better in that regard.īefore that development, I found that I could prevent active videos from disrupting the page-merge process by working from a copy of the webpage, rather than the original. Unfortunately, the panorama software had problems with this task: it might be able to combine only a few images at a time it might balk at overlapping screenshots that captured a playing video, because those screenshots would capture different parts of the video and thus would not overlap precisely it might not be able to produce an image beyond a certain length. Then I tried using panorama-maker software (e.g., Photoshop Microsoft’s Image Composite Editor) to combine those screenshots into a single image. ![]() In a previous effort, I had started with a batch file that would capture screenshots every half-second, as I scrolled down the page. ![]() Over time, I actually started to prefer the last of those alternate approaches. Notes at the end discuss some alternate approaches. This post describes the steps I took to achieve that, using ImageMagick. ![]() I had a long webpage that I wanted to save as a single image (e.g., JPG or PNG). ![]()
