When you have a fairly large web application project you are coding, it’s pretty inevitable that you “know where the bodies are buried” (if you’ll pardon our amateur dramatics). We’ve known about one for years with our inhouse Animated GIF Creator project (we last talked about at Animated GIF Slide Extraction Applied CSS Styling Tutorial), chipping away at it, but not cracking it to our satisfaction, concerning …
- when a user creates an animated GIF …
- derived of image slide sources of differing dimensions …
- up to today, we were allowing for this in a user selectable dropdown but not doing a good job of flagging that to the user … it occurred to us …
- today, on non-mobile, we’ll make the size attribute of that dropdown be the number of subelement option elements it has so that a non-mobile user can see all this happening … sorry, mobile users … and …
- add more four options, namely …
- Always Pick Maximal Dimensions
- Always Pick Minimal Dimensions
- Always Pick Maximal Width+Height
- Always Pick Minimal Width+Height
… as a “set and forget” way a user can strategize their animated GIF output dimensioning no matter what else goes into the “slide mix”
At least for non-mobile we feel that this changed PHP tutorial_to_animated_gif.php inhouse animated GIF creator web application is worth retrying regarding these Javascript modifications …

We dedicate today’s blog posting to the English phrase (that maybe works in other languages) …
… as it is about the pros and cons of HTML iframe integration, especially as it applies to CSS styling. Off the top of our heads we see a Pros and Cons table looking like …
Pros and Cons of HTML Iframe Based Web Application Software Integration | |
---|---|
Pros | Cons |
Become tools | Difficulty with styling integration especially regarding time of coding differences |
Become modularised | Focus within iframe can cause problems |
Ability to begin again at (0,0) regarding positioning | Hashtag navigation within iframe can cause problems |
Sharing the coding and execution load | |
Software organizational advantages | |
Can glean information off parent and vice versa | |
New chance for synchronizations | |
Multitasking | |
Coding language mixing | |
Parent child interactions |
… and, as you can see, we are mainly fans of what it can bring to the table (mild chuckle, followed by a chortle).
But that first Con can grate, that “Difficulty with styling integration especially regarding time of coding differences”, and today, we thought we’d “apply” to relevant (there was one we found we should not “apply” the thinking to) HTML iframe “child” styling using yesterday’s Animated GIF Slide Extraction CSS Styling Tutorial‘s CSS styling idea in the “parent” (“applied” to these children).
We used a “suck it and see” approach whereby we just, where applicable, appended the CSS <style></style> styling logic of yesterday (plus a bit) to the document.body “body” innerHTML attribute of the iframe called, to see whether it felt more integrated. And we thought it did, perhaps because that styling was one of the more generic feeling ones we can remember (by that we’re meaning that the selectors were often just HTML tag names rather than too much “class” or “id” aspects to those selectors). Also, sometimes it won’t work because adding to the document.body innerHTML can sometimes “muck up” logic (but not today).
And what allows for “deploying” such an idea? Inhouse, we call what we do here “Client Pre-emptive Iframe” ideas, where the relevant iframe element’s “onload” (or on rare occasions, “onerror”) events are used to add logic at a slightly later time to any HTML iframe document.body element’s “onload” logic would be applied. This is a powerful mechanism open to you if you are dealing with same domain parent/child URLs, that is the case for us with this work today.
It’s as easy to do as (showing you one iframe “onload” function example below, and with inline CSS usage, rather than an external CSS file usage (where it would be even easier)) …
var paconto=null;
function pcheckit(iois) {
paconto = (iois.contentWindow || iois.contentDocument);
if (paconto != null) {
if (paconto.document) { paconto = paconto.document; }
if (paconto.body != null) {
setTimeout(function(){
if (document.getElementById('pmyifthree')) {
document.getElementById('pmyifthree').scrolling='no';
}
document.getElementById('myifthree').scrolling='no';
paconto.body.innerHTML+='<st' + 'yle> ' + document.head.innerHTML.split('<st' + 'yle>')[1].split('</st' + 'yle>')[0] + ' </st' + 'yle>';
paconto.getElementsByTagName('select')[0].style.display='none';
paconto.getElementById('image').style.display='none';
paconto.getElementById('isub').style.display='none';
paconto.getElementsByTagName('div')[0].style.opacity='0.0';
paconto.getElementsByTagName('select')[1].style.display='none';
paconto.getElementsByTagName('h1')[0].style.opacity='0.0';
if (1 == 1) { paconto.getElementsByTagName('h4')[0].style.opacity='0.0'; }
if (1 == 1) { paconto.getElementsByTagName('h3')[0].style.opacity='0.0'; }
}, 12000);
}
}

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 …

}
“; ?>
… 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>
<iframe onload=pcheckit(this); style='display:inline-block;width:80%;height:160px;' id=myifthree src='/PHP/read_exif_off_image_rotate.php#itwo'></iframe> <a id=atotop style='display:inline-block;vertical-align:top;width:15%;text-shadow: -1px 1px 1px #952dff;' onclick="window.scrollTo(0,0);" href='#mydet'>⬆ Top</a>

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 …

- 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 scrollable toable.
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.

To make this happen, amongst the …

- 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 …
… 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 …
