Recently, when we presented Media Representation of URL Tutorial we outlined the current state of play for us when asked to represent a URL in a media form, when we said …

• Google Page Speed Insights could supply an image data URI of a screenshot of that URL as a web browser webpage … but now out of reach to us … and/or …
• Google used to supply a data URI QR Code image representation … but now out of reach to us … so our research got us to the excellent …
• goqr.me free API means to a data URI QR Code image representation … thanks

There, we shored up our https://www.rjmprogramming.com.au/recording_ideas.php Media Middle Manager in this regard.

And today, in a similar vein to above, applied to the thinking behind up to today (for a wee while) non functional HtTp and hTtP prefixing logic parts to the Animated GIF Creator web application of the recent Osascript AppleScript Copy and Paste Ideas Tutorial we start redirecting URLs to allow QR Code URL representations to be represented as animated GIF slide QR Code data URIs via two new Javascript functions …

Previous relevant Osascript AppleScript Copy and Paste Ideas Tutorial is shown below.

Yesterday’s Animated GIF Slide Clipboard Automation Tutorial clipboard themes has spurred today’s interests in …

• macOS
• osascript
• AppleScript
• command key ideas regarding …
  1. Select All … command-A
  2. Copy … command-C
  3. Paste … command-V

  … thinking

… and whether, back at a webpage it can be useful. So far, we have just made a start with …

• osascript_it.php … included by …
• using_osascript_it.php

So far the jury is out?!

Previous relevant Animated GIF Slide Clipboard Automation Tutorial is shown below.

Onto yesterday’s Animated GIF Slide Clipboard Tutorial one might say …

We can do better.

… and, well …

Nala	Luna
Do fish swim?	What is the optimal pH range for the denaturation of polymerase in a standard PCR protocol?

… and though Luna’s observations have merit … mind you …

The question seems to be based on a misunderstanding of the standard PCR process. The polymerase used in a standard PCR, such as Taq polymerase, is a thermostable enzyme and is not denatured at the high temperatures and standard pH conditions used in the protocol; its stability at high heat is what makes PCR possible.

… we’re agreeing with Nala (and who knows^? … maybe Luna) in saying …

• regarding Windows (eg. MAMP) incarnations … phase one improvements could happen
• regarding macOS (eg. MAMP) incarnations … phase one improvements and some quite interesting phase two automation improvements, that, given some permissions yielded over to MAMP, could have the pasting off the Clipboard automated to email or SMS messaging conduits be happening

Yes, in phase one we’ve improved …

• any slide textbox ending up with a URL prefixed by http://localhost can have right click logic working for it (in addition to the “last one only off a browsed for set of image files” scenario of yesterday)
• the user can toggle (via the header “… or …” (now, when relevant, span element) new onclick event logic) between “a” link “mailto:” email and “sms:” message conduit modes

… and phase two …

• uses macOS osascript AppleScript smarts to (perhaps, it depends on Sytem Settings permissions regarding your Apache local web server application’s Accessibility permissions) paste Clipboard contents into email or SMS bodies programmatically ahead of any user control … but …
• that meant we had to fill out email To: and Cc: and Bcc: and SMS To: fields with data the user is bound to want to override (because we wanted the cursor to be appropriately positioned ahead of the automated pasting from Clipboard automations)

And so, you might think of all this as “nuance” and that could be a fair interpretation, but there is for some, we have no doubt, the chance to get your “automation ideas” flowing too, perhaps?!

Yesterday’s “recall of thyself” now looks like …

The recent excitement in the underlying operating macOS system last talked about at Local Operating System Menu Pbcopy macOS Clipboard Tutorial recently regarding the command line commands …


pbcopy and pbpaste


… we now realize could benefit from a little temporing, along with Window’s “clip” equivalent command because …

• they only ever work for clipboard data that is “text” … and today’s idea, in our minds, involved graphical (image) data … and so research led us to …

• macOS	Windows
  osascript -e ‘set the clipboard to (read (POSIX file “/path/to/your/image.jpg”) as JPEG picture)’ Thanks to great advice of pbpaste equivalent for graphics in clipboard	powershell.exe -Command “Add-Type -AssemblyName System.Windows.Forms; [System.Windows.Forms.Clipboard]::SetImage($([System.Drawing.Image]::Fromfile(‘C:\Path\To\your_image.png’)))” Thanks to great advice of windows graphics into clipboard via command line

  … instead, for ideas regarding the clipboard with “graphical” data

We wanted to apply this thinking to any “last defined” slide of an animated GIF creation (via PHP web application discussed with Animated GIF Slide Extraction User Experience Tutorial) session where the user browses for their input image files off the local operating file system in either …

• right click event logic is added so that an “a” “mailto:” link inspired mail client email can be created awaiting the user pasting that Clipboard image contents into the body of the email as an attachment

Previous relevant Animated GIF Slide Extraction User Experience Tutorial is shown below.

We often equate the term “user experience” with “niceties”, in that we often find we deal with “user experience” issues well into a project, but you can put more effort into forward design planning so that you deal with it better throughout the project. We found with the Animated GIF Slide Extraction project of yesterday’s Animated GIF Creation Canvas Integration via Slide Extraction Tutorial that issues that had annoyed us for several days past, but which did not stop the web application working, turned into a day where we felt that we were improving the “user experience” by “fixing annoyances” and “adding niceties”, today. As you might imagine, this can be subjective, because just because we think an idea is an improvement does not mean every user out there will think so, and this is where time set aside for real users to try a product (ie. user acceptance testing) ahead of “going live” can be a great idea.

Anyway, there was …

• an annoyance, on non-mobile, we first introduced when we integrated Animated GIF Creation in with Animated GIF Slide Extraction a couple of days ago … too much cursor:progress; usage … and in fixing we were astonished that cursor:wait; displays the same graphics … anyway, we think it helps when a cursor can help a user get used to identifying wherein the workflow they are situated at any given time …
  <?php echo ”
  
function cursorcheck(defisidea) {
if (window.parent) { if (parent.document.getElementById('cursorchoice')) { if (parent.document.getElementById('cursorchoice').value != '') { return parent.document.getElementById('cursorchoice').value; } } }
return defisidea;
}

  “; ?>
  … looking to parent …
  
<input data-choice='' type=hidden value='help' id='cursorchoice'></input>

• we felt better adding <hr> horizontal rule elements above and below the middle HTML iframe we set aside for client browsing functionality … and also …
• made that iframe less wide enabling us to place to the right of it a hashtag navigational “a” link back up to the top …
  
<hr>

Previous relevant Animated GIF Creation Canvas Integration via Slide Extraction Tutorial is shown below.

Thinking about yesterday’s Animated GIF Creation Data Limits via Slide Extraction Tutorial‘s progress …

What about if the user is happy to use those filled in animated GIF slide textboxes (with delay and title) to create a user created (and downloadable) animated GIF there and then?

Well, we know that user could click their own presented button, but we wanted to flag it up at the parent ahead of time too, in terms of clarity in the changed seventh draft extract_ag_slide_huh_of.html Animated GIF Slide Extraction web application (or Animated GIF Slide Extraction via User Interaction web application version), which you can try below.

So, what’s all this got to do with an HTML canvas element (in case we have readers who take notice of the nuances of blog posting titles, that is)? Well, once you reach the stage with our inhouse Animated GIF Creator web application, where it has created your own animated GIF image, there is an “onclick” subsection of functionality that, in our new scenario, suffered from an error 404 (Bad Request) because the codeline ran as …

<?php echo ”

canvwo.push(window.open('/HTMLCSS/user_of_signature_signature.htm?slide=' + tid.replace(/^slideshow1$/g,'slideshow') + useyourwords, '_blank', 'top=' + eval(screen.height - hw) + ',left=' + eval(screen.width - hw) + ',width=' + hw + ',height=' + hw));

“; ?>

… but got that error because variable useyourwords contains an animated GIF “first slide” data-URI (useful in that a [canvasContext].drawImage() call of it would do what “drawImage” does with animated GIFs anyway (going back to the original point regarding this whole thread of blog postings)) which caused an overshoot of data size limits on conventional ($_GET style) address bar URLs (perhaps involving ? and & arguments (whether they be five minute or ten minute ones)). But regular readers will know, for a happy couple of months now, we recognize we do not always have to call into play serverside PHP and its $_POST mechanisms here, because we can also call on our life changing hashtagging (ie. #) (clientside approach for HTML/Javascript/CSS webpage) ideas now! Yay!!!!! And so, it came to pass, that … yes … there was light on yonder hill … and vale … whatever that is … as “we broke bread” … shall we say … let’s … with some new hashtagging code in the changed PHP tutorial_to_animated_gif.php inhouse animated GIF creator web application …

<?php echo ”

if (eval('' + ('' + '/HTMLCSS/user_of_signature_signature.htm?slide=' + tid.replace(/^slideshow1$/g,'slideshow') + useyourwords).length) <= 800) {
canvwo.push(window.open('/HTMLCSS/user_of_signature_signature.htm?slide=' + tid.replace(/^slideshow1$/g,'slideshow') + useyourwords, '_blank', 'top=' + eval(screen.height - hw) + ',left=' + eval(screen.width - hw) + ',width=' + hw + ',height=' + hw));
} else {
canvwo.push(window.open('/HTMLCSS/user_of_signature_signature.htm?slide=' + tid.replace(/^slideshow1$/g,'slideshow') + useyourwords.replace('&','#'), '_blank', 'top=' + eval(screen.height - hw) + ',left=' + eval(screen.width - hw) + ',width=' + hw + ',height=' + hw));
}

“; ?>

… as above and with the changed user_of_signature_signature.htm User of Signature Signature inhouse canvas graphic data web application “canvas hoster” …


var thewords=(location.search + location.hash).split('thewords=')[1] ? decodeURIComponent((location.search + location.hash).split('thewords=')[1].split('&')[0]) : "";
if (thewords.indexOf('data') == 0) { thewords=thewords.replace(/\ /g,'+'); }


… to bring “canvas integration” into the mix.

Previous relevant Animated GIF Creation Data Limits via Slide Extraction Tutorial is shown below.

Even PHP’s $_POST[] approach to HTML form navigation data sharing has it’s limits, and that can be challenged when considering a whole set of data-URI defined animated GIF slide images.

But, behind the scenes, when $_POST[] does not get filled out with regard to the data limits of the Apache/PHP/MySql (in our case) web server involved, there is still php://input …

PHP provides a number of miscellaneous I/O streams that allow access to PHP’s own input and output streams, the standard input, output and error file descriptors, in-memory and disk-backed temporary file streams, and filters that can manipulate other file resources as they are read from and written to.

php://stdin, php://stdout and php://stderr ¶
php://stdin, php://stdout and php://stderr allow direct access to the corresponding input or output stream of the PHP process. The stream references a duplicate file descriptor, so if you open php://stdin and later close it, you close only your copy of the descriptor-the actual stream referenced by STDIN is unaffected. It is recommended that you simply use the constants STDIN, STDOUT and STDERR instead of manually opening streams using these wrappers.

php://stdin is read-only, whereas php://stdout and php://stderr are write-only.

… we can turn to (thanks, PHP), that can save the day in a lot of these scenarios.

The thing is, which our parent HTML and Javascript can help with, we want to be flagging the scenario where we should be checking that php://input usage might be coming into play. Well, even for an HTML form method=POST action=[ourRelevantPHP] scenario, the PHP global $_SERVER[‘QUERY_STRING’] is honoured, shall we say (separate to any $_GET[] ideas, is what we are getting at here). So we can, at the client HTML and Javascript parent (and client) end, set a unique $_SERVER[‘QUERY_STRING’] condition to test for in a changed sixth draft extract_ag_slide_huh_of.html Animated GIF Slide Extraction web application (or Animated GIF Slide Extraction via User Interaction web application version), which you can try below, nuancing yesterday’s Animated GIF Creation Interfacing via Slide Extraction Tutorial …


<form id=agf style=display:none; method=POST data-target=ifconto action='/PHP/animegif/tutorial_to_animated_gif.php?theword=numfillin'>

Previous relevant Animated GIF Creation Interfacing via Slide Extraction Tutorial is shown below.

The work of today combines …

• the day before yesterday’s Animated GIF Slide Extraction Reveal Tutorial progress with our Animated GIF Slide Extractor web application … and …
• yesterday’s Animated GIF Multiple Onload Slides Tutorial progress with our Animated GIF Creator web application as a more useful tool

… to add the chance for a user to use what ImageMagick produces as an Animated GIF slide and fill this out into the textboxes of the Animated GIF Creator “child” iframe hosted incarnation “quietly” filled out probably “below the fold”, but scroll_able to_able.

There are data limits to what the Animated GIF Creator can handle, but perhaps it can help a user create their own Animated GIFs, for their own purposes, via other sources.

Sources for courses

… we’d say. But we would say that, wouldn’t we?!

To make this happen, amongst the …

1. PHP … and …
2. Korn Shell

… helper components (to get to ImageMagick) we swap the “tidying up of interim files” role Korn Shell used to do, quite successfully (and still does for any interim “whole Animated GIF” files created), passing the responsibilities to the PHP to do (via passing over to the Korn Shell a new extra argument, to tell it this is the new arrangement). And at the changed third draft agtoslides.php PHP (working with the changed third draft agtoslides.ksh), before the “outputting command line” is executed, a whole lot of “child asks stuff of the parent” “programming talk and action” happens (and works, because our Client Pre-emptive Iframe Onload Event logic looks for that iframe document’s document.body.innerHTML as the representation of the extracted slide (of the animated GIF) of interest) …

Previous relevant Animated GIF Slide Extraction Reveal Tutorial is shown below.

Around here, we’re not ashamed to simplify 90% of web design issues into two categories …

1. an “overlay” issue … or …
2. a “reveal” issue

… and today’s improvements, pitted against the progress up until yesterday’s Animated GIF Slide Extraction Absolute URL Tutorial, pitted these two “colossuses” (at least in our mind) against each other as concept ideas towards today’s work’s solution. Which wins? We opted for a “reveal” solution, where the initial position is “reveal”.

We could have “overlayed” but we went for the KISS (“keep it simple simpleton”) principle, where, what you see at the top of a webpage takes prominence for the user. The thing is, though, in this alternate input section, we are not fussed that it stays around, hence the details/summary “reveal” way a user can make it disappear at any given point in time.

Here’s the thing, though, a details/summary “reveal” pairing has that “summary” innerHTML content part that can remain, no matter what, as a status informer mechanism we’re hoping helps out the “formerly obtuse” web application ways of our Animated GIF Extraction web application, in a changed fourth draft extract_ag_slide_huh_of.html Animated GIF Slide Extraction web application (or Animated GIF Slide Extraction via User Interaction web application version), which you can try below.

Previous relevant Animated GIF Slide Extraction Absolute URL Tutorial is shown below.

The other user entry the user might do using the Animated GIF Slide Extraction web application of yesterday’s Animated GIF Slide Extraction Browsing Tutorial onto …

• relative animated GIF URL (within the address bar domain of use or an absolute URL serving similar purposes) … and yesterday’s …
• browsed for local animated GIF file of interest … is today’s …
• absolute URL pointing to a domain not the same as the address bar domain of use

As you might guess this last option for the user may not work for a domain with very high security, but being as hotlinking images makes the Internet woooorrrrllllddd go around perhaps the user can try this underlying curl based logic out, to see with a changed third draft extract_ag_slide_huh_of.html Animated GIF Slide Extraction web application (or Animated GIF Slide Extraction via User Interaction web application version), try below.

You may have noticed in our first draft we were not concerned with two incarnations of the web application being executed at once. Back then, one might interfere with the next if interrupted during the serverside ImageMagick phase of creating the png slides off the input animated GIF. Recently, we have started using …

… based logic (but in non-SQL realms) for that ImageMagick work. By and large the internal use only interim file naming in this ImageMagick phase is 99.9999999% sure to be unique to your session, and so not interfering, or accidentally picking up, other sessional data. You might want to look out for a textbox named “random”, in the code, regarding how we make that happen …

Would you believe …
