Contact Us Feedback Animated GIF Tutorial

We can’t imagine how much longer it would have taken us to suss out the solution to our desire of having our Animated GIF email attachments for the “Feedback” web application not have a black background without great advice from Stackoverflow‘s great link. Yesterday’s Contact Us Feedback Smoothly Filtering Tutorial told of the virtues of “empirical” thinking. Today we come back to the advice of the knowledgeable. Both approaches have their worth.

You may have wondered about why this is an issue. Well, the PHP imagegif method has had a bit of a chequered history in the PHP GD image library, perhaps regarding its flakiness retaining opacity, something the PNG image format is best at. The Animated GIF, via data URI, creation code needs all the bold bits specially regarding GIF work below …

$eachonestring=" \$text=''; // Open the first source image and add the text. \$underimage = imagecreatefromjpeg('source01.jpg'); \$old_width = imagesx(\$underimage); \$old_height = imagesy(\$underimage); \$image = imagecreatetruecolor(\$old_width, \$old_height); \$black = imagecolorallocatealpha(\$image, 254, 254, 254, 0); imagefill(\$image, 0, 0, \$black); imagecopyresampled(\$image, \$underimage, 0, 0, 0, 0, \$old_width, \$old_height, \$old_width, \$old_height); imagecolortransparent(\$image, \$black); \$text_color = imagecolorallocate(\$image, 200, 200, 200); imagestring(\$image, 5, 5, 5, \$text, \$text_color); // Generate GIF from the $image // We want to put the binary GIF data into an array to be used later, // so we use the output buffer. ob_start(); imagegif(\$image); \$frames[]=ob_get_contents(); \$framed[]=40; // Delay in the animation. ob_end_clean(); // And again.. ";

Perhaps the crucial code line, here, is imagecolortransparent(\$image, \$black); using your selected “masking” colour (and background colour) as the basis for manipulating the image on “all but that colour”, which we chose as that wee bit different to white, but looks like white as your new Animated GIF background colour.

We don’t mind a black background, but it is a bit awkward for a couple of reasons …

any pure black text (and we often choose black for text) will disappear into a black background
the result of the HTML5 canvas [canvasElement].toDataURI(‘image/png’,0); has a white background, so there is quite a degree of inconsistency if we make no attempts at today’s changes

… as you can see with the finished Animated GIF we created that inspired the tutorial picture above, below …

As you might surmise …

PHP tutorial_to_animated_gif.php code changed the most to cater for these Animated GIF background colours in this way or try it as a live run … supervised by …

Around here we think it’s fairer on you readers to be quite empirical about the study of web applications. That’s not to say we don’t have the utmost respect for all that the great Stackoverflow website offers regarding great analysis of issues and ideas in this area, thanks. Nevertheless … and didn’t you know there wouldn’t be a but, exactly?! … to be empirical means we can at least say that we try web applications we talk about under some platforms and web browsers, ourselves, and so can say at the time of writing such and such display such and such a behaviour. Ideally, we’d mention versions of things much more, but for us, that is too far over the top for the technicality we wish to impart, with this blog.

Yesterday’s Contact Us Feedback Filtering WordPress Tutorial gave us some “filtering” capabilities, but the way it flashed the “whole shebang” temporarily at the start wore away at our “programming conscience”, and we determined that us knowing in our minds “that the web application display doesn’t stay that way” is just not good enough, nor fair, in the sense that there are a lot of users out there, in this day and age of interruption, that might interpret this “flashing” of disappearing functionality as “suss”, so we set out on a web application client approach to refining this behaviour to not have this “flashing” look. Before we go further, it should be noted that if we were prepared to use PHP serverside thoughts here you could research the incredibly useful ob_end_clean(); and ob_start(); and ob_get_contents(); approaches, these being so useful they are intrinsic to speed improvements that effectively zip up the blog contents you are reading right now (and which you can read more about at EasyApache in cPanel Primer Tutorial) to solve this dilemma.

For us to solve it we empirically determined that …

document.body onload=onloading(); event trapping … will not cover …
after <body onload=onloading();> the <script type=’text/javascript’> document.write([HTMLgoesHere]); </script>

… the (empirical) lesson being that, even though it is more awkward and disparate to do this, you must address the “if” statements required with that “after <body onload=onloading();> the <script type=’text/javascript’> document.write([HTMLgoesHere]); </script>” as described above, otherwise you remain with the flashing as we can show you (or refresh for you) below …

… <iframe id=’notsmooth’ src=’//www.rjmprogramming.com.au/HTMLCSS/feedback.htm?justideas=maybe‘ title=’Word Search’></iframe> that is a “smoother” display (or refresh if you want to see in action, for yourself) via the improved … <iframe id=smooth src=’//www.rjmprogramming.com.au/HTMLCSS/feedback.htm?justideas=y‘ title=’Word Search’></iframe> …

A variation that justified our optimistic self delusion “that the web application display doesn’t stay that way” is good enough, is that …

you quickly click that first refresh link above …
quickly click inside the “To:” textbox …
if you are quick enough the “full shebang” shows else if you didn’t click in this field or were too slow, the “reduced shebang” shows Deluded self: “A feature rather than a confusion.” … and what causes this to happen ..
1. we make “justideas=y” the value of a global variable … var basis=”justideas=y”; (and make it so that this basis global variable is used everywhere in the code except in the first two “if”s just after “<body onload=onloading();> the <script type=’text/javascript’> “) …
  var exs=''; if (document.URL.indexOf('justideas=') != -1) exs='display:none;'; // start with nothing if (document.URL.indexOf('justideas=maybe') != -1) exs='';
2. change the workings of the “To” textbox as per
  document.write("To: <input onclick=\"basis=basis.replace('justideas','nowayjose');\" style='width:200px; align:right;' type='email' id='myto' onblur=\" fixto(this.value); \" value=''></input><br>");

The improved feedback.htm HTML and Javascript feedback “reduction” functionality that changed from that last time in order for the content to be smoothly “reduced” (aka ?justideas=y) in this way and which you can test for yourself at this reduced live run link (the independent way, or the WordPress way) or full functionality live run link.

Previous relevant Contact Us Feedback Filtering WordPress Tutorial is shown below.

Yesterday’s Emoji Contact Us Feedback Filtering Tutorial‘s new filtering functionality related to a “section” of the “Feedback” web application it was applied to. And this exemplifies, for us, that the term “modularisation” can take on various “levels” of modularisation such as …

high level modularisation as per MVC types of coding styles that modularise the underlying code, and in all likelihood, the “look” of the resultant web pages … all the way through to …
… OOP code classes line up with web application “item look” … to …
a web application “looks modular”, with elements organized into “container” elements, but to look at the Javascript, and maybe the HTML of the web application, it is hard to see any of this “modularisation” in terms of its code

If it is your job to “reduce” a web application into a “contained” section of the web page display of that web application, even that (most rudimentary) last level of “modularisation” above is fine to …

work out what differentiates normal “busy” display from the pared down “reduced” look … today, for us, it’s ?justideas=y added to our URL to become today’s reduced live run link (as distinct to a full live run link)
work out codewise how to manifest that difference above, and that is, for us …
if (document.URL.indexOf('justideas=') == -1) { // pared down "reduced" look code goes here } else { // normal "busy" display code goes here }
think about when and where to intervene in the code, so that you can come up with a code line like today’s …
if (document.URL.indexOf('justideas=') != -1) { document.body.innerHTML='<div id=ideas>' + ideasprefix + amongthis + ideassuffix + '</div>'; } else if (navigator.userAgent.match(/Android|BlackBerry|iPhone|iPad|iPod|Opera Mini|IEMobile/i)) { document.getElementById('ideas').innerHTML=ideasprefix + amongthis + '<br><iframe id=ideasiframe style="display:none;-webkit-overflow-scrolling:touch;overflow:scroll;" src=""></iframe>' + ideassuffix; } else { document.getElementById('ideas').innerHTML=ideasprefix + amongthis + ideassuffix; }

… where ideas is an element “ID” (of a “container” element) both before (when it is a table cell (td) element) and after (when it is a div element, on its own within the document.body’s content (ie. its innerHTML))
… for us, that being the successful HTML iframe onload event (Client Pre-emptive Iframe logic) code, after which the HTML dropdown containing blog posting unique word “option” tags are complete
use a web inspector to see where else in the whole Javascript logic you’ll need to refine with “if (document.URL.indexOf(‘justideas=’) != -1) { } else { }” interventions, via those web inspector Console tab errors, that are bound to occur instigating the steps above

So this leaves us with “why?”. Well, what is a “section” of the “Feedback” web application could happily sit as a WordPress Blog menu item, because we can imagine you, the reader, could benefit as a researcher, or “driller innerer oferer more detail and more specificity” might like to hone in on a particular blog posting topic of interest using this technique.

What of the WordPress end of this interfacing of functionality? Further down the “well” (tee hee), this is as easy as falling off a log …

Pick a menu item name, ours being “Word Search”
as admin of your WordPress Blog use the Add Page icon to type “Word Search” into the title field … and then in the “body textarea” …
<iframe src='//www.rjmprogramming.com.au/HTMLCSS/feedback.htm?justideas=y' title='Word Search'></iframe>
Add or Update into the WordPress Blog menu

Sew if you like, while you see the feedback.htm HTML and Javascript feedback functionality that changed from that last time to be able to be “reduced” (aka ?justideas=y) in this way and which you can test for yourself at this reduced live run link (the independent way, or the WordPress way) or full functionality live run link.

Do not know if you have been trying the functionality in the third table cell up near the top of the Feedback web application last talked about at yesterday’s Emoji Contact Us Feedback Email Animation Tutorial but if you have (or haven’t (welcome aboard)) that dropdown in that third cell contains all the blog postings on this blog, as a prompter for a topic of an email you could send to us as an email piecing together your feedback.

Today’s improvements concern two areas …

redelving into our favourite HTML “reveal” tool, the details/summary partnership and the idea that the summary part of this could contain an HTML select (dropdown) element … and you might call today’s work the “guinea pig project” here, as we expect to improve, and also …
finding a way, that we think has great potential, for people using this blog for research and development and/or as a learning tool, a “filtering” mechanism to hone in on topics of interest (which now can open a popup or iframe (for mobile)) to any chosen blog posting of interest

How do we determine topics of interest? Scan every word we’ve ever used in a blog posting title, and if that word satisfies a few criteria, and hasn’t been mentioned before, gets added to an array of different such words, sorted at the end and added (ie. appended to the HTML select element’s innerHTML property) to the pre-existing options of that details/summary dropdown, that being …

… or as HTML (with innerHTML being emboldened … I’d just give up and take it to the beach …

… if I were you) …

<select id='bigselect'><option value=''>Ideas:</option><option value='Cut to the Chase'>Cut to the Chase</option><option value='Feedback'>Feedback ... all versus ...</option></select>

… whereby if the user selects one of these “filterers”, they being given lowercase values, we filter that dropdown’s initial “big content” filtering it down into “little content” via that tried and true ~~Siri dropdown, go and filter~~re-establishment of a smaller innerHTML property for that details/summary dropdown, the understanding being we can at any time go back to the “big content” by re-establishing the innerHTML to this (Javascript) global variable value should the user repick one of those non-lowercase options.

What’s “Cut to the Chase”? It’s our trying to help busy blog readers just wanting to jump to executing the “action item” of a blog posting straight away.

So, see the feedback.htm HTML and Javascript feedback functionality that changed from that last time in this way and which you can test for yourself at this live run link.

Adding to yesterday’s Emoji Contact Us Feedback Animation Tutorial‘s Feedback animation beginnings, after today’s work, we can email animated GIF animations via an email attachment.

As you might imagine, using data URIs can avoid some file creation but asks a lot of data transfer techniques, hence the need below (in an example of 4 slides to an animated GIF where you can imagine the huge data URI strings within the src=””s below) with the HTML form navigation used between the supervisor and the animated GIF creator PHP …

… needs that method=”POST” to work these animated GIF creations.

We must say here, that to use an animated GIF is just one slideshow (or animation) approach, and we mention many other ideas regarding slideshow usage. Another we thought about would have involved HTML attachments that use no Javascript, just CSS, to create animations via document.body background images. We may try this technique further down the track.

Emoji Contact Us Feedback Animation Tutorial

As we said early on in the recent blog postings on this thread of postings last talked about with yesterday’s Emoji Contact Us Feedback Copy and Paste Tutorial …

… but we envisage, optimistically, to involve animation and more refined positioning possibilities

Well, the news is, we’re getting closer, by allowing for the “internal use only” creation (and playing) of an animation slideshow from changing canvas image representations, if that is what you want to do, that is. It uses a self-destructing HTML div element presentation we’re not sure whether we’ve ever used before. As you may know, an HTML div element, being the “container” (innerHTML) element that it is, can self-destruct via a myriad of methods, the last of which below being our method for today’s work …

Javascript DOM [divElementObject].style.display=’none’;
Javascript DOM [divElementObject].style.visibility=’hidden’; // this one may leave whitespace depending
Javascript DOM [divElementObject].style.width=’0px’; (or [divElementObject].style.height=’0px’; … you get the gist?)
Javascript DOM [divElementObject].style.top=’-700px’; (or [divElementObject].style.left=’-500px’; … you get the gist?)
Javascript DOM [divElementObject].style.opacity=’0′;
Javascript DOM [divElementObject].style.fontColor=’transparent’; // if data is textual and this one may leave whitespace depending
Javascript DOM [divElementObject].className='[classThatMakesDivElementInvisible]’; (or [divElementObject].className+='[classThatMakesDivElementInvisible]’; … you get the gist?)
Javascript DOM [divElementObject].innerHTML=”;

… which we make happen today, after that HTML div is given the contents of each “slide” of the animation (or slideshow), separated, just for now, via a 4 second delay as per …

var filmslidenumber=1, fromfilmslidenumber=0, tofilmslidenumber=0;


function tanimation() {

  if (fromfilmslidenumber < tofilmslidenumber) {

  document.getElementById('dslideshow').innerHTML='<img style="border:8px dashed lightblue;" src=' + document.getElementById('tablefilmimg' + eval(1 + fromfilmslidenumber)).src + '></img>';

  fromfilmslidenumber++;

  setTimeout(tanimation, 4000);

  } else {

  document.getElementById('dslideshow').innerHTML='';

  }

}
function animation() {

  fromfilmslidenumber = 0;

  tofilmslidenumber = eval(-1 + filmslidenumber);

  document.getElementById('dslideshow').innerHTML='<img style="border:8px dashed lightblue;" src=' + document.getElementById('tablefilmimg1').src + '></img>';

  location.href='#dslideshow';

  fromfilmslidenumber++;

  setTimeout(tanimation, 4000);

}

… helped out by additional HTML as per …

document.write('<table style=width:100%;><tr><td><div id=dslideshow></div><h1 id=myh1 align="center">Feedback</h1></td><td style=width:90%; nowrap><div style=display:inline-block;width:100%;overflow-x:scroll; id=dviai><form style=display:none;width:100%;overflow-x:scroll; action=fairy_story_assistant.php method=GET target=fsa><input name=emoji id=iemoji value=></input><input type=submit id=isubm value=Submit></input></form><iframe style=display:none;width:100%;overflow-x:scroll; id=fsa name=fsa src=></iframe></div></td></tr></table>');

… and some changed Javascript as per …

Now to think about emailing these optional animations.

Today, also, we’ve made the CSS much better suited to the mobile devices you may be using, by introducing the equivalent canvas onclick event logic mapped to the touchstart event, that mobile devices detect.

Emoji Contact Us Feedback Copy and Paste Tutorial

We’ve got quite a variety of functional improvements on top of what was there already with yesterday’s Emoji Contact Us Feedback Cross-Browser Tutorial (optionally email) Feedback web application. These changes, today, in brief, involved …

copy and paste with the canvas element whose image representation forms the body of an email sent via this web application
in order to ensure the consistency of canvas (y or top) positioning we had quite a lot to do, such as …
1. no longer placing the image that results from “Send Feedback and Show Body of Email as Image” up the top right, but now to under the canvas with a pink dashed border (for clarity)
2. no longer making the emojis map (big) into the header h1 element but now in a table cell as per …
  <td style=width:90%; nowrap><div style=display:inline-block;width:100%;overflow-x:scroll; id=dviai><form style=display:none;width:100%;overflow-x:scroll; action=fairy_story_assistant.php method=GET target=fsa><input name=emoji id=iemoji value=></input><input type=submit id=isubm value=Submit></input></form><iframe style=display:none;width:100%;overflow-x:scroll; id=fsa name=fsa src=></iframe></div></td>
  … ensuring it takes up as little height as possible, but stretches out to the right as much as it likes, but you can scroll to those parts way out off the screen to the right
allowing some web browsers make use of their HTML5 input type=color colour wheel methods of defining annotation and canvas drawing foreground colour
inform the user, via a self-closing popup window, that the PHP mail has sent an email, the look of which has a little bit of “Android toast” about it

So let’s talk about the “Copy (via 2) and Paste (via 1) Parts of Canvas Above to Canvas Above”. After a little dead end thinking pixel level thoughts might be the go … no … it was image level thoughts we needed, trapped at the canvas element’s onclick logic …

the Copy (via 2 click/touch) aspects via [canvasElement].toDataURL(‘image/png’,0) copies the whole canvas, but while we are at that we are recording the user’s last two click’s …
1. The x coordinate where to start clipping
2. The y coordinate where to start clipping
3. The width of the clipped image
4. The height of the clipped image
… which we’ll come back to, and now to convert that into image data (for the statically defined HTML <img id=’myim’ style=’dispay:none;’ src=” title=” alt=”></img>), we …
omyimgdata=elem.toDataURL('image/png',0); document.getElementById('myim').style.width=elem.style.width; document.getElementById('myim').style.height=elem.style.height; document.getElementById('myim').src=omyimgdata; omidatax=eval(Math.min(x,lastx)); omidatay=eval(Math.min(y,lasty)); omidataw=Math.abs(x - lastx); omidatah=Math.abs(y - lasty);
the Paste (via 1 click/touch) aspect using the “full might” of the [canvasContext].drawImage() calling incarnations as per …
context.drawImage(document.getElementById('myim'),omidatax,omidatay,omidataw,omidatah,x,y,omidataw,omidatah);

Emoji Contact Us Feedback Cross-Browser Tutorial

Yesterday’s Emoji Contact Us Feedback Textarea Tutorial had us more integrated involving emojis with the HTML5 canvas element we use as the source for an image attachment to a potential email for use as Feedback, perhaps.

There are cross-browser issues here.

Firefox is not transferring the emojis to the canvas, at least for us.
And Safari does not offer great two finger gesture options when hovering over the canvas, such as “Save Image As…”. So, today, we offer those Safari users the chance to be able to “Save Image As…” image (email attachment) download possibilities by offering a new button called “Send Feedback and Show Body of Email as Image”. Use this, and that image that results is downloadable.

In order to allow for that last one, and not wrongly overlay the Annotations div element menus, we adjust the top (y) co-ordinate of the Annotations div element menus as per …

if (document.getElementById('divannotation')) { if (('' + document.getElementById('divannotation').style.top).indexOf('485') != -1) { document.getElementById('divannotation').style.top=eval(eval(('' + document.getElementById('divannotation').style.top).replace('px','')) + 300) + 'px'; } }

… a technique that may fail for elements that do not define the top property, whether that be teamed or not (as for today) with position:absolute property …

document.getElementById('divannotation').style.top='485px';

Emoji Contact Us Feedback Textarea Tutorial

Yesterday’s Emoji Contact Us Feedback Integration Tutorial started us down the road of trying to make emoji usage more functional with the annotation aspects of our Feedback (Contact Us type of) web application.

We have a textarea HTML element currently in use as a means by which we collect textual data, that may go into the feedback, and then onto an email, perhaps. We’ve lately been preferring to use …

div contenteditable=true … in preference to …
textarea

… and though we keep the textarea as the interfacing element of “textual data collection” for the user, today, it gets helped out by accompanying …

div contenteditable=true … and encompassing the textarea we have a new …
div … acting as a parent

How come? Well, in our experience, when you mix up the keyboard character type of text with emoji HTML Entity “textual” data, the relationship between the textarea’s …

value property
innerHTML property

… unique among elements, and really generally useful, stuffs up, or we stuff up, one of the two.

But … and didn’t you just know there’d be a “but” … combine the content of the first “shadowing” div element with a complete rewrite of the textarea via the innerHTML property of the “encasing” second div (parent) element and you can go back to the conditions at the start of the web application, as far as the textarea is concerned, where you can place HTML Entity representations of that mix of textual data that may include emojis, into the textarea’s innerHTML via code like …

// store current innards of the textarea var mtv=top.document.getElementById('myfeedback').value; // at to those textarea innards the current HTML Entity emoji data addition and place into the innerHTML of the "shadowing" div contenteditable=true element top.document.getElementById('dmyfeedback').innerHTML=mtv + cnotatend; // clear contents of textarea top.document.getElementById('myfeedback').value=''; // repopulate textarea in an innerHTML (HTML Entity friendly) way by reinstating its whole (outerHTML) instantiation by setting the innerHTML of that textarea's encasing div element, and in between where > meets </textarea> place that same div contenteditable=true innerHTML where spaces map to (HTML Entity)   top.document.getElementById('ddmyfeedback').innerHTML='<textarea style="color=lightgray;width:200px;" rows=6 cols=40 id="myfeedback" title="Feedback" value="" onchange=" pseudo_sentence=this.value; placetext(); " onblur=" pseudo_sentence=this.value; placetext(); ">' + mtv.replace(/\ /g,' ') + cnotatend + '</textarea>';

A couple of days ago we presented Contact Us Feedback Primer Tutorial as shown below … and said …

Maybe you remember reading about the recent Feedback functionality here at RJM Programming when we presented Feedback Email Attachment Iframe Tutorial. It struck us that it would be good to extend the “Contact Us” webpage here at RJM Programming by adding a “Feedback” form to the “Contact Us” now presented via an HTML select “dropdown” element.

… well, we discovered down the track that the behaviour of the HTML a tag’s mailto: href parameter navigation needs to be nuanced for Android (mobile) usage.

A bit of reading on this lead us in one direction and the useful link pulled us completely back into a good line, thanks, via the advice …

window.top.location = “http://example.com”;

… but, for us, that goes (something like) …

window.top.location = "mailto:fill.in@email.address?subject=blah&cc=&bcc=&body=Lots%20Of%20Blah";

… presumably to get the external Android Mail app into the picture. On the way this link was useful, also, so, thanks.

Maybe you remember reading about the recent Feedback functionality here at RJM Programming when we presented Feedback Email Attachment Iframe Tutorial. It struck us that it would be good to extend the “Contact Us” webpage here at RJM Programming by adding a “Feedback” form to the “Contact Us” now presented via an HTML select “dropdown” element.

You can see the gist of what is involved with today’s tutorial picture for the creation of a short worded feedback email, via your default email client (ie. an HTML a mailto: link is used), perhaps regarding a tutorial here at this blog, which can be chosen via an HTML select “dropdown” element populated from the RJM Programming Landing Page, the logic for which you can read about with Client Pre-emptive Iframe Crontab Curl Rotated Report Tutorial. As you would glean from this blog posting title, what we are involving here is …

WordPress Blog’s MySql database
curl call of PHP to extract blog posting information
crontab scheduled execution of PHP to assemble this data into an updated HTML select “dropdown” element in the RJM Programming Landing Page

an HTML iframe element loads the Landing Page and the crontab/curl inspired PHP/MySql data is extracted (at that iframe’s onload event) and reworked to the purposes of this Feedback functionality
