                      A single archive file that contains the common source code and compiled Java files shared by all book editions: imagingbook.jar

                      A dedicated ZIP archive BurgerBurge..-plugins.zip for each book edition that contains a set of ImageJ plugins, structured by individual book chapters.

                      Common archive (required for all): [imagingbook.jar](https://dl.dropbox.com/s/03by3ctfwf9k6fw/imagingbook.jar)

                      Select the dedicated plugin set for your book edition: Professional Edition: [download](https://dl.dropbox.com/s/ub5rh30wwxjs58p/BurgerBurgeEn1-plugins.zip) Undergraduate Series (Vol. 1-3): [download](https://dl.dropbox.com/s/z6utfwsm8vv4trs/BurgerBurgeUtics123-plugins.zip) German Edition: [download](https://dl.dropbox.com/s/xdu3p50sbr3vqf1/BurgerBurgeDe1-plugins.zip) Chinese edition: same as Professional Edition

                      Place imagingbook.jar in the <IJ>/plugins/jars folder (create this folder if it does not already exist).

                      Expand the zip file with the dedicated plugin set inside the  <IJ>/plugins folder. Each book chapter is represented by a sub-folder in plugins.

                      Place the additonal JAR files in <IJ>/plugins/jars.

                      Start ImageJ, chapters and contained plugins should now be visible in the 'Plugins' menu. Use 'Compile and run..' to execute plugins after any modification. Note that this source code is being continuously updated, enhanced and adapted to newer releases of Java and ImageJ. Thus some of the original code examples in the printed texts may have been replaced by newer and improved versions without notice, although we attempt to preserve the original functionality as much as possible. This may affect class structures, method parameters and coding practices in general. The API thus cannot be guaranteed to be stable and may be incompatible with older code.

                      QUESTION

                      Take screenshot of full page with Selenium Python with chromedriver

                      Asked 2020-Jan-14 at 20:20

                      After trying out various approaches... I have stumbled upon this page to take full-page screenshot with chromedriver, selenium and python.

                      The original code is here. (and I copy the code in this posting below)

                      It uses PIL and it works great! However, there is one issue... which is it captures fixed headers and repeats for the whole page and also misses some parts of the page during page change. sample url to take a screenshot:

                      http://www.w3schools.com/js/default.asp

                      How to avoid the repeated headers with this code... Or is there any better option which uses python only... ( i don't know java and do not want to use java).

                      Please see the screenshot of the current result and sample code below.

                      full page screenshot with repeated headers

                      You can achieve this by changing the CSS of the header before the screenshot:

                      topnav = driver.find_element_by_id("topnav")
                      driver.execute_script("arguments[0].setAttribute('style', 'position: absolute; top: 0px;')", topnav) 
                      

                      EDIT: Put this line after your window scroll:

                      driver.execute_script("document.getElementById('topnav').setAttribute('style', 'position: absolute; top: 0px;');")
                      

                      So in your util.py it will be:

                      driver.execute_script("window.scrollTo({0}, {1})".format(rectangle[0], rectangle[1]))
                      driver.execute_script("document.getElementById('topnav').setAttribute('style', 'position: absolute; top: 0px;');")
                      

                      If the site is using the header tag, you can do it with find_element_by_tag_name("header")
