WebSnapperPro Tutorial

TESTIMONIALS

I had excellent technical service experience with the crew at Tasty Apps. In this modern age, it can very hard to get quality service, especially on a technical level. These guys really knew their stuff and were so detailed in their advice, that it actually restored my troubled Mac Pro back to peak performance. Very, very impressed. Tasty Apps sets a standard of service that the whole country can and should follow as an example. — Sean Davey, http://seandavey.com


(...) diligent, tenacious and relentless product support (...) — Danny McCall, http://www.talentsphere.com


A ground-breaking & revolutionary array of software for Mac, Tasty-Apps' products and further tech support is so reliable - I would thoroughly recommend them to anyone. — Ryan


I've been using TastyApps' products (Videobox, Musicbox, Web Snapper, and FlagIt!) since 2009. I'm a huge fan of their products, and have also become a huge fan of their Technical Support. As a Macintosh Consultant and Software Instructor, this is not a phrase I often have the opportunity to say, and in the case of TastyApps, I'm more than pleased to be able to say it. (...) I can't say enough good things about TastyApps' Support Services. I heartily recommend their software, their company, and their Tech Support. — Stephanie Gans, http://www.aym4training.com


I didn’t use my copy of VideoBox much UNTIL I discovered that it can convert Elgato EyeTV MPEG2 files (QuickTime Pro cannot). If ever Easy VHS to DVD crashes while converting a recording (It records in MPEG2 format) – the ONLY App I have that CAN convert the leftover MPEG2 files to QuickTime MOV is VideoBox. So, Instead of paying Apple $20 for a Quick time MPEG2 Converting Plugin: I recommend you Buy VideoBox for $15 to do the Exact same Job! — Carl McCall, http://softwaresanta.com/


(...) the renew license was very easy to use and in minutes my VideoBox was working. In a time where support for most companies really sucks—I appreciate your quick and thorough turnaround to my issue—thanks for the support. — Scott Medina, http://www.isminc.com

OVERVIEW

WebSnapperPro allows you to capture full web pages from your web browser with a single mouse click without the need to “stitch” or cut and paste individual screenshots.

You can save the page capture as an image file – most popular types supported – or as a vector based PDF file. You can also print the captured page, send it as an email attachment, send it to Evernote (if installed), or export it to your DropBox account, right from the WebSnapperPro interface.

INTERFACE



WebSnapperPro launches with an animated camera icon and single "Add"    button in the Download queue. Use the button to add the active page in your browser to the WebSnapperPro Downloads queue. The button can be set in Preferences to automatically call Safari or Chrome for 1-click functionality, or it can allow you to choose sources "on the fly,including URLs from your Pasteboard.

You are not limited to Safari or Chrome...with the available WebSnapperPro Bookmarklet, any browser can be used, as explained in the Operation section below.

As you add pages for processing they will be added to the queue, along with options for processing the pages.

OPERATION

WebSnapperPro provides 4 different capture methods: The Safari Extension (for OS X 10.12 and above only), the "Add" button   , the Bookmarklet, and the MiniBrowser. For most pages the the results will be the same, but there can be differences. See "Advanced Capture Techniques" below.

WebSnapperPro also allows "batch" captures using a text list of URLs. See "Batch Captures" below.

Safari Extension

For OS X 10.12 and above you can install the included Safari Extension. The Extension captures the source of the website, including any dynamic modifications you have made.

With Safari closed, launch WebSnapperPro, then launch Safari and open Safari Preferences from the Safari menu.



From the Safari Preferences screen select the "Extensions" Tab.



Make sure the checkbox for WebSnapperPro in the left column is checked. Quit and relaunch Safari and the WebSnapperPro Extension    will be added to your toolbar.



While viewing a page in Safari, just click on the WebSnapperPro Extension to launch WebSnapperPro and add the target page to the downloads queue. If WebSnapperPro is already open, the Extension will just add the target to the queue. You can continue adding target pages with the Extension.

The   "Add"  button

You can use the "Add"    button – when you want to capture a page you are viewing in Safari or Chrome. Just click the button and the target page will be added to the WebSnapperPro downloads queue. The button will capture the page source with any dynamic modifications you made on the page - even if the page is protected by a login/password, as the page source is copied directly from your browser. (Note: In Safari, an extra configuration step is needed) This is usually the most reliable method...but there can be exceptions. See "Advanced Capture Techniques"below.

Bookmarklet

If you are not using Safari or Chrome you can use the available Bookmarklet to capture webpages. The Bookmarklet works in all browsers. (See "Advanced Capture Techniques" below.)

Just drag this button

WebSnapperPro

and drop it onto the bookmarks bar in your browser, The Bookmarklet will appear on your browser bookmarks bar.

When viewing a web site in your browser just click the WebSnapperPro Bookmarklet on your browser bookmarks bar and WebSnapperPro will grab the current page for processing. If WebSnapperPro is not already opened when you click the Bookmarklet, the Bookmarklet will open WebSnapperPro and add the target page to the Downloads Queue for processing. With WebSnapperPro open, the Bookmarklet can provide the same 1-click functionality of the "Add" button.

MiniBrowser

WebSnapperPro has an internal MiniBrowser that can be called for difficult pages that rely heavily on external content. See "Advanced Capture Techniques" below.


In the example below three pages have been added to the downloads queue. You can process all the pages in the download queue with a single click using one of options of the multipurpose button    at the bottom of the interface.



The multipurpose button allows you to: Process All, the items in the queue; Clear All, the items; or just Clear Completed, items.

When you select Process All, WebSnapperPro will process all the items in the Downloads queue using your default Output Preferences settings.

The multipurpose button also allows you to Save or Email, all the pages in the downloads queue to a single multipage PDF.

Don’t confuse the “Multipage Saving...” options with the "Pagination" option in the Preferences settings. Pagination is automatically enabled when using any of the "Multipage Saving..." options, and page breaks (8.5 X 11) will be inserted into long PDF documents for printing and easy on-screen viewing. Without automatic pagination, long webpages would be reduced to fit on a single sheet and the result could be a narrow image - the longer the page, the narrower the image.

You can also process or delete pages individually using the "Save"    and "Delete"    buttons just beneath the URL of each item in the queue.

When processing pages individually, you will get a screen that allows you select output settings for individual pages.



NOTE: The "Save" button will make the capture. Changes here are page specific and will not effect your default Preference settings.


Snapping Local Pages: WebSnapperPro is not only for capturing pages from the Web. You can also capture local HTML pages by dragging an HTML file to the camera icon in GUI. The file will be added to the Download queue as a regular item.

Creating Multi-Page PDFs: You can also drag several PDF files to the camera and WebSnapperPro will create a single, multipage PDF file for you.

DropBox Integration: WebSnapperPro has the ability to export snapshots in any format to your DropBox account. To use this feature, just select DropBox as your destination in the Snapshot preferences. You will need to link WebSnapperPro to your DropBox account in WebSnapperPro Preferences.



Click on the "Link to DropBox" button. Your default browser will appear and you will see a webpage asking you to allow WebSnapperPro to access its own folder inside your DropBox.



Click "Allow".

Depending on your browser, you might be asked "Do you want to allow this page to open WebSnapperPro"?



It is important that you click "Allow" on this screen.

You can confirm the integration was successful by checking the DropBox tab in WebSnapperPro Preferences. The button should now read "Unlink from DropBox".

Now, if you select "DropBox" as your Destination in WebSnapperPro Preferences, your snapshots will appear under the folder Apps/WebSnapperPro.

After a snap is completed with a Destination: DropBox, the URL of the WebSnapperPro folder in your DropBox will automatically be copied to your Pasteboard.


ADVANCED CAPTURE TECHNIQUES

As stated above, WebSnapperPro provides 4 different capture methods (The Extension, the "Add"    button, the Bookmarklet, and the Mini Browser). For most pages the results of these 4 methods will be the same, but there can be differences.

The Extension, the    button, and the Bookmarklet communicate with your browser and will capture any dynamic changes you have made including login credentials.

But there may be some situations when the Extension, the    button, and the Bookmarklet will not work as expected. When the individual images or other resources on the page you are capturing are also protected by a login/password you might see some blank spaces instead of the content shown in your browser. The solution is to use the Mini Browser. (See below)


And NOTE when using the Safari option on the     button; to properly resolve dynamic modifications to a page (opening menus, closing cookie notes, etc.), Safari needs to allow JavaScript from Apple Events.

Open Safari Preferences and on the Advanced tab, click the "Show Develop menu in menu bar" box at the bottom of the window.



This will put a "Develop" menu option on the Safari toolbar. Open the "Develop" menu and select "Allow JavaScript from Apple Events". Confirm and enter a password if required.



Please Note: On some systems the "Allow JavaScript from Apple Events" may not work. This is a known Apple bug and we are trying to find a work-around. At this time the only solution for this is to use the Bookmarklet, the Mini Browser, or Chrome with the Chrome Insta-Link button

WebSnapperPro will inform you if your system has the bug. A "warning" icon     will appear on the left, just above the Downloads queue when you select Safari as the capture source.

Mini-Browser: The Mini Browser can be invoked for a specific item in the queue by clicking on the URL just above the page URL of the item in queue. (See Operation screenshot above) The minibrowser will open and reload the target page. You can then modify the page dynamically (by clicking on buttons, expanding tabs, etc). When you are done, click the snap button in the top left   (see screenshot below) and the WebSnapperPro Mini-Browser will capture the page.




With the mini-browser, you can also resize the mini-browser window to trigger web responsive changes in the web page. For example, if you reduce the window size, the aspect of the page might vary (by hiding menus or triggering a mobile view, for example). If you then hit the snap button at the top left of the mini-browser, WebSnapperPro will capture the page with these modifications. Finally, the Mini Browser is the safest approach to bypass password protected pages. Just log in as you would usually do in your regular browser, and get to the page you want to capture.

Sierra and High Sierra: Vector mode is less reliable in Sierra and High Sierra. Beginning with Sierra OS X 10.12, Apple's implementations of PDFKit (e.g. Preview) and WebKit (the Apple engine WebSnapperPro uses), have caused some problems.

If you are capturing a page with PDF output format, Vector conversion mode, you might get a PDF so "big" that Preview or Acrobat Reader might not be able to handle. Namely, preview might show a blank or distorted PDF in Sierra and High Sierra, and Acrobat Reader might display the page trimmed in OS X 10.9 and above, or in Windows.

The solution to this problem is to enable the "Use Pagination option" in WebSnapperPro Preference settings, or alternatively use an image format instead of PDF (e.g. PNG). Or, you can use Google Chrome to open the PDF, as it is the only engine for OS X that is able to properly handle these PDFs.

Missing images or content in the webpage: Techniques used on some web pages to conserve bandwidth and improve page rendering speed can keep content hidden until the browser calls for it. Scroll to the bottom of the page to force javascript to load the missing content before calling WebSnapperPro to make the capture.


BATCH CAPTURES

You can use a manual Drag N Drop method to capture a list of URLs.

First, in WebSnapperPro Preferences, General tab, check the Enable batch mode option. Next highlight a text list of URLs and then drag and drop it onto the animated camera icon at the top of the WebSnapperPro Interface. WebSnapperPro will process each URL in the list one by one, discarding the previous before moving on to the next, keeping memory usage to reasonable level.

Remember to disable batch mode in Preferences when done.

Please note: Manual Drag N Drop may not be as reliable on pages with dynamic content and some content may not be captured.
