Emoji Image Creator or Media Paster Multiple Copy Synchronize Tutorial

Emoji Image Creator or Media Paster Multiple Copy Synchronize Tutorial

Adding onto yesterday’s Emoji Image Creator or Media Paster Multiple Copy Background Tutorial “Multiple Copy/Paste of Files” improvements, today we’re getting more into the head of a user of the “Copy Media” button encouraging the Copy of files over to the “Paste” area div element via macOS Finder or Windows Explorer, in the sense that …

• programmatically we’ve deemed it the web application’s role, if possible, to synchronize audio/video media “play” … if …
• the user has gone to the trouble to Copy over more than one audio/video file sets of data … presumably because (though we do not look into, or enforce, this) …
• video has just visuals and the audio could be a voiceover for that video, or perhaps two audios are two voices that sound good merged (ie. synchronized), or perhaps two videos played together synchronously make sense explaining an issue or product

… all evidential to your regular reader of this blog’s continuation with …


Media Synchronization


… that a lot of you readers out there will know is a near impossibility with mobile devices. Those readers who study “the masochism of RJM Programming regarding media synchronization” will be interested that we exhausted another avenue of thought. We played around (with some small proof of concept HTML) …

• nested an “audio” element within a “video” element …
  
<video id=myvideo controls><source type='video/mp4' src='ants.m4v'></source><audio id=myaudio controls><source type='audio/mp4' src='audiocapture.m4a'></source></audio></video>

  … and then clicked “play” for either … no go regarding synchronization
• nested a “video” element within a “audio” element and then clicked “play” for either … no go regarding synchronization
• nested an “audio” element’s “source” subelement within a “video” element and then clicked “play” for either … no go regarding synchronization
• nested a “video” element’s “source” subelement within an “audio” element and then clicked “play” for either … no go regarding synchronization

… at least also trying to see whether a click by a parent can flow through to a media element to perhaps satisfy the iOS need for a click to instigate (media) “play”. Ooooohhhh well!

But back in “non-mobile land” we change the code to entrench that hosting “div” element (of potential media elements) “onclick” logic to point to the changed Javascript “function predotogglei()” below …


var medialist=[];
var thismediaid='';

function divclick() {
if (eval('' + medialist.length) > 1) {
for (var iu=0; iu<medialist.length; iu++) {
//document.title+=' ' + medialist[iu].id;
if (eval(iu % 2) == 0 || 1 == 1) {
medialist[iu].play();
} else {
medialist[iu].autoplay=true; //play();
medialist[iu].load();
}
}
}
}

function predotogglei() {
var toti=0;
var cumy=0;
var ims=document.getElementsByTagName('img');
var zrect=null;
var yrect=document.getElementById('editor').getBoundingClientRect();
divclick();
bpos=''; //0px 0px';
bsiz=''; //0px 0px';
for (var jjims=0; jjims<ims.length; jjims++) {
if (('' + ims[jjims].className) == 'togglei') {
toti++;
}
}
for (var jims=0; jims<ims.length; jims++) {
if (('' + ims[jims].className) == 'togglei') {
if (bpos == '') {
bpos='0px 0px';
zrect=ims[jims].getBoundingClientRect();
cumy+=eval('' + zrect.height);
bsiz='auto ' + zrect.height + 'px';
} else {
bpos+=',0px ' + cumy + 'px';
zrect=ims[jims].getBoundingClientRect();
cumy+=eval('' + zrect.height);
bsiz+=',auto ' + zrect.height + 'px';
}
}
}
if (bpos != '') {
document.getElementById('editor').style.backgroundPosition=bpos;
document.getElementById('editor').style.backgroundSize=bsiz;
}
}


… is made useful via changed “collection (of media) logic” Javascript as per (an “audio” element example) …

<?php echo ”

thismediaid='media' + medialist.length;
document.getElementById('editor').innerHTML+='<audio id=' + thismediaid + ' controls><source type=\"' + ('' + btypes[curnum]) + '\" src=\"' + duis + '\"></source></audio>';
medialist.push(document.getElementById(thismediaid));
if (eval('' + medialist.length) > 1) { document.getElementById('editor').title='Click me for synchronized audio/video play where allowed.'; }

“; ?>

And so our changed PHP emoji_image.php live run chips away at the implications of “Multiple Copy/Paste media file sets” in terms of trying to synchronize the “play” of (albeit probably only non-mobile) media files that benefit from synchronization, because we have assumed our users know what they are doing?! And don’t they just!?

With the recent Emoji Image Creator or Media Paster Multiple Copy Tutorial‘s introduction of …

• allow for Copy of multiple files in the jQuery logic … and today we …
• add a new button “Copy Media” for the user who will Copy multiple image/audio/video media
• add “Paste here” to table cell’s div contenteditable=true element in which the user should Paste their data
• allow for background images to this Paste cell … whose …
• corresponding real img elements for each background image, when clicked, can download that image data for the user

Regarding the positioning of these multiple background images we need to reference those real img element coreespondents, as per the new Javascript function …


function predotogglei() {

var cumy=0;
var ims=document.getElementsByTagName('img');
var zrect=null;
var yrect=document.getElementById('editor').getBoundingClientRect();

if (('' + ims[jims].className) == 'togglei') {
if (bpos == '') {
bpos='0px 0px';
zrect=ims[jims].getBoundingClientRect();
cumy+=eval('' + zrect.height);

} else {
bpos+=',0px ' + cumy + 'px';

bsiz+=',auto ' + zrect.height + 'px';
}
}
}
document.getElementById('editor').style.backgroundPosition=bpos;
document.getElementById('editor').style.backgroundSize=bsiz;
}


Yes, you guessed it. There’s still far more to what we might do regarding reading a user’s mind when they copy and paste multiple files over, and that is still a work in progress, along with cross-browser issues and how to handle multiple background or border image usage, but for now, feel free to try this new multiple copy/paste background image download functionality, which exists in our changed PHP emoji_image.php live run, for yourself, again, in your yurt.

Could there be another “onions of the 4th dimension” amendment left that could help our project, the “Emoji Image (and media)” web application of yesterday’s Emoji Image Creator or Media Paster Aesthetics Tutorial? We think so.

You see, when we added that Audio and/or Video media functionality, did anything occur to you regarding …

• the procedure recommended to do Audio and/or Video data … or even …
• the very idea, anyway

? It’s pretty optimistic thinking users would just select a single Audio or Video file to copy over to our web application, and fit in with its (previous) “limited view”. Pretty obviously, we’d like to cater for multiple file selections both in the Audio or Video scenario there, plus the idea of a user ignoring Google Pagespeed (third party) help, and opting to use macOS Finder or Windows Explorer to select multiple image files, or various media mix combinations.

Do you see what a Pandora’s Box we are opening ourselves up to with this? Yes, it will take more than today to get this Multiple Copy (and Multiple Paste) functionality to be smoothly integrated. Our biggest start down that road, though, is that jQuery access of the HTML5 File API “onloadend” arrangements. If you just think the “one file” usage here will work for “multiple file” usage, the way it was, think again. We did, with the web application of Image/PDF and Audio/Video Supervised Rotation Tutorial, luckily, as a conduit to a reunderstanding of that more complex jQuery and File API Javascript required now, for this …

If you have been following our latest “Emoji Image (and other media)” project of yesterday’s Emoji Image Creator or Media Paster Download Tutorial you will know we have two (publicly displaying) “incarnations” of the inhouse bit of the PHP webpage …

1. first incarnation asks for user input via user interaction … including storming out …
2. second incarnation shows results and now allows for downloading results as HTML snippets

… and today we try to minimize the numbers of people storming out we hope. This is something running in our favour here, as these changes concern the first incarnation above.

• if you have a webpage waiting for user interactivity it doesn’t matter …
• if you load it with display intensive CSS (such as our “glow” animations) … it doesn’t matter … you’re waiting there anyway … plus you are self-explaining

And there is not much better, to our mind, for “self-explaining” and helping that little bit with internationalization, of your web application than to …

• use emojis … and fortunately for us with this web application here …
• involve “end results” of what your web application might achieve … and fortunately for us with this web application that is emoji image border images and background images

A new block of CSS for that first incarnation is our progress, today, then (where data uri have been [nicknamed] below) …

And in order for this to “value add” let’s arrange for the user to be able to “download” second webpage incarnation elements of interest, by clicking them, after initially (just) displaying them.

… before we say “BIye” to the Emoji Image themed blog postings here.

As many users will know, emojis can be the graphically-challenged user’s ticket to …

• personalization
• graphical and aesthetic appeal of webpages
• attracting attention to your content

… that is much easier than learning the graphical expertise Photoshop and Gimp usage encourages. But too much emoji usage can look a bit predictable too, so we are not discouraging you from learning any of those graphical expertise skills.

Emojis are limited from a lot of CSS styling border and background image usage, but we can convert those Emojis into images here, which is the gist of what we are on about here on this blog posting thread.

In order to show a bit of background image work we sprinkle the webpage with four CSS styling examples of usage (ordered from the top to bottom and left to right) …

<style>

1. #hthree { background:linear-gradient(rgba(255,255,255,0.3),rgba(255,255,255,0.3)),URL([asBelow]); background-size:cover; background-repeat:no-repeat; }
2. #thone { background:URL([asBelow]); background-repeat:no-repeat; }
3. #thtwo { background:linear-gradient(rgba(255,255,255,0.3),rgba(255,255,255,0.3)),URL([asBelow]); background-repeat:repeat; }
4. #result { background:linear-gradient(rgba(255,255,255,0.3),rgba(255,255,255,0.3)),URL([asBelow]); background-size:contain; background-repeat:no-repeat; }

</style>

… and added dynamically because …

• <style> CSS </style> is not restricted to just <head></head> but can also work within <body></body> … and …
• for that <body>[document.body.innerHTML]</body> usage Javascript (DOM, within document.body.innerHTML) can dynamically add the CSS styling at a time of the programmer’s choosing

And so yet again, here is our changed PHP emoji_image.php live run for you to take up both the Border Emoji Image CSS Challenge and, now, Background Emoji Image CSS Challenge!

• CSS Border Images (made from data-uri data of these recent Emoji Images) … we had to “crack” “the ol'” …
• automating the cropping of bottom and right whitespace

… because you will find only the top border image bits “filled out” if the imagery in the CSS “border-image:URL([data-uri data of these recent Emoji Images]);” has a lopsided whitespace feel to it. PHP can easily do this out of the box from PHP 5.5 onwards via its GD library imagecropauto function. Alas, up at the RJM Programming domain we are on PHP 5.4 and so ended up being helped out enormously by the brilliant ideas on this wonderful link, thanks.

Okay, so we can arrive at a whitespace cropped Emoji Image data uri, what then? Well, we recommend you read …

• border image … and off that, most importantly, perhaps …
• border-image-slice property

… and we display a couple of examples of uses of Border Images using the resultant Emoji Image data uri you create.

So, are you ready for the challenge? Yet again, here is our changed PHP emoji_image.php live run for you to take up that Border Emoji Image CSS Challenge!

We have a couple of “onions of the 4th dimension” amendments to yesterday’s Emoji Image Creator Primer Tutorial …

• the display format scope of the Emoji Image Creator “palette” (“shall we say now … eh wot ‘guv”) extends from single line of entry to be able to handle multiple lines of entry … and Emojis being text that means either …
  1. div contenteditable=true … but we have plumped for …
  2. textarea

  … means by which to make this thangthing happen manperson

• the sharing scope of the Emoji Image Creator goes from “keeping everything to yourself” to “sharing via Email (email client or Inline HTML Email) or SMS”

… your Emoji Image creations. And …

“Where do ya get it?”

… here? … or am I missing something? Can’t be … I’m writing this.

Glad that’s over!

And back to matters at hand, how do we handle that “require” attribute we’d placed on yesterday’s lonesome textbox? Well, we get around that by setting an empty textbox to a space should the user only enter Emoji data in that new textarea (that circumvents the “require” attribute validation restriction), and deploy logic that takes into account PHP variables where …

<?php

$gei="";
if (isset($_GET['emoji_textarea_image'])) {
$gei=str_replace("+"," ",urldecode($_GET['emoji_textarea_image']));
}

if (trim($gei) != "" || isset($_GET['emoji_image'])) {
if (trim($gei) == "") {
$gei=str_replace("+"," ",urldecode($_GET['emoji_image']));
} else if (isset($_GET['emoji_image'])) {
$pregei=str_replace("+"," ",urldecode($_GET['emoji_image']));
if (trim($pregei) != "") {
$pregei.="\n\n" . $gei;
$gei=$pregei;
}
}
file_put_contents('emoji_image.txt', str_replace(";","",str_replace("&#","",str_replace(";&#",".",$gei))) );
// more logic follows to continue the work below ...
}

?>

… PHP function trim comes to our aid, as it so often does in “PHP land” (or as String.trim() does in “Javascript land”) with backward compatibility for dual purpose scenarios.

And again, here is our changed PHP emoji_image.php live run for you to retry, and perhaps, share!

We’ve long eyed up the wish to have emojis (which you need to know are text (and this very fact is the reason for this whole project)) be involved with a border image or background image or just with some image in work developing web applications. And so we joined forces with (and thanks to) …

• Google PageSpeed
• Stack Overflow
• jQuery

… along with …

• textbox reachable “Emoji and Symbols” menu to include Emoji characters (though we also accept Emoji CodePoint(s) too)
• Copy and Paste technologies …
  1. Copy (Image) from Google PageSpeed
  2. Paste to HTML div contenteditable=true via Stack Overflow and jQuery
• your own desktop Image Editors … for example …
  1. Gimp can Crop and Resize and Select to new Image via Copy then Paste
  2. Preview and Paintbrush (here on macOS) can Resize and Select to new Image via Copy then Paste

  … can help remove any extraneous whitespace coming off the Google PageSpeed Copy image

With all this help coming our way you’d think we might get away just using HTML and Javascript, but no, we need PHP, we figure, using a web browser file to toggle between web application executions that have no arguments as either …

• it means we display our inhouse interactive entry mode of use when that file does not exist … whereas …
• we arrange it so that it is a call from Google PageSpeed when that file exists (as we morph inhouse content into a single p element containing the Emojis in such a scenario) as Google PageSpeed takes its screenwebpageshot

So here is our PHP emoji_image.php live run …
