Emoji Borders and Backgrounds QR Code Tutorial

Some web browsers such as Google Chrome also have “right-clicking (for Windows) and two finger gesturing (for macOS and Mac OS X)” menu QR Code options, further to QR Code URL via macOS Two Finger Gesture Option Tutorial and yesterday’s Emoji Borders and Backgrounds Web Browser Tutorial.

And, if we bring “third party” and inhouse together, we can help out with QR Code “sharing” via links or QR Code images (ready for mobile device Camera app usage), as another collaboration idea.

It’s the great Google as our “third party” today, specifically their Google Charts -> Infographics -> QR Codes, functionality that has been so brilliantly useful with this endeavour, offering a GET methodology to hook up an Inhouse “SVG -> IMG -> CANVAS” URL with a QR Code image, the one catch being that we are only allowed “?” GET arguments in the “third party” interfacing. No worries there, we just place, up near the top of the PHP code …

<?php

$udirname=explode("canvas_svg.php", str_replace("::",":","http://" . $_SERVER['SERVER_NAME'] . ":" . str_replace("~","",str_replace(":443~","",str_replace(":80~","",(":" . $_SERVER['SERVER_PORT'] . "~"))))) . "" . $_SERVER['REQUEST_URI'])[0];
$qrbig="http://chart.googleapis.com/chart?chs=300x300&cht=qr&chl=" . $udirname . "canvas_svg.php&choe=UTF-8";
if (isset($_GET['justtheone']) && strpos(('' . $_SERVER['QUERY_STRING']), '&') === false) {
header('Location: ' . str_replace('http:','',$udirname . 'canvas_svg.php' . '?' . urldecode(str_replace('justtheone=','',$_GET['justtheone']))));
exit;
} else if (('' . $_SERVER['QUERY_STRING']) != '') {
$qrbig="http://chart.googleapis.com/chart?chs=300x300&cht=qr&chl=" . $udirname . "canvas_svg.php?justtheone=" . urlencode($_SERVER['QUERY_STRING']) . "&choe=UTF-8";
}

?>

… to interface our changed PHP canvas_svg.php SVG -> IMG -> CANVAS live run web application with optional QR Code image sharing and collaborating functionality.

Emoji Borders and Backgrounds Web Browser Tutorial

Yesterday’s Emoji Borders and Backgrounds Shape Sharing Tutorial had us sharing via email or SMS our “Emoji Borders and Backgrounds” creations via inhouse organized arrangements. But many people are used to just right-clicking (for Windows) and two finger gesturing (for macOS and Mac OS X) on …

  • SVG
  • IMG
  • CANVAS

… graphical elements, which can be made to “look” the same, and sort of “suck it and see” as far as menu options presented, helping them out sharing graphical information. In many cases, users don’t care what form of element the image comes contained in. But, if you involve “background-image” CSS along the way to achieve a (consistent) “look”, as we had done before today, (some of) the output of those menu options could be lacking (because they look for “foreground data”), and so we do away with the need for a “background-image” …

<?php


function ctoilater() {
img.src=canvas.toDataURL('data/png');
}



if ((iurl != '' && document.URL.indexOf('noimage') == -1) && emoji != '') {
//imgs[0].style.background='URL("' + iurl + '")';
//canvases[0].style.background='URL("' + iurl + '")';
if (emoji != '') {
imgs[0].style.backgroundPosition='20px 20px';
}

imgs[0].style.backgroundRepeat='no-repeat';
canvases[0].style.backgroundRepeat='no-repeat';


var newimg=document.createElement('img');
newimg.onload = function() {
// draw the image onto the canvas
if (document.URL.indexOf('emoji=') != -1) {
canvas.getContext('2d').drawImage(newimg, 20, 20);
} else {
canvas.getContext('2d').drawImage(newimg, 0, 0);
}
setTimeout(ctoilater, 3000);
}
newimg.src = iurl;


}

?>

… look on the IMG and CANVAS element usage (as above) and use the great way a …

  • CANVAS can contain merged image data … and a …
  • CANVAS can convert back to an image data URI

… to mean IMG and CANVAS can end up united in a “real image data” look and content, via SVG that can be made up of …

  • emoji TEXT
  • user TEXT
  • user IMAGE (like IMG)
  • user shapes CIRCLE and/or ELLIPSE and/or RECT and/or LINE and/or POLYLINE and/or POLYGON … and inhouse NOIMAGE

… (SVG) “streams” of graphical data.

We also needed to cater for that inhouse “NOIMAGE” shape lack of IMAGE data in our changed PHP canvas_svg.php SVG -> IMG -> CANVAS live run web application.

Did you know?

An example of how having web browser (right-clicking (for Windows) and two finger gesturing (for macOS and Mac OS X)) menu options be useful, consider an image menu option such as “Copy image” be used by the user. The user can compose their own (email client (or get to email client via all uppercase web application “to” email “address” definition)) email then, and just Edit -> Paste the results, as an image, into the email body, ahead of sending off that email.

The code “shape shifting” of recent times morphs into “shape sharing” together in amongst the parent users of our PHP tool “Emoji Borders and Backgrounds” web application featuring in yesterday’s Emoji Borders and Backgrounds Shape Numerics Tutorial.

We found the “SVG+XML” mimetype data not accepted by Gmail for an Inline HTML Email, so we have coded for the Downloadable HTML Attachment “way to go”.

Emoji Borders and Backgrounds Shape Numerics Tutorial

If you are familiar with the geometry of shapes, it is full of numbers, with the implications as to how the shape is represented and displayed, that those numbers can affect. And so, onto yesterday’s Emoji Borders and Backgrounds Shapes Tutorial‘s start with …

  • SVG circle element
  • SVG rect element … shapes yesterday, we add …
  • SVG ellipse element functionality today … and for all these, as well as the …
  • SVG text element we start allowing “shape numerics” as being a user definable thaing

These “shape numerics” can help the user control (that SVG element’s) …

  • position
  • size
  • opacity
  • font size … (for text elements) on top of that non-numeric control yesterday’s work gave us, being (that SVG element’s fill) …
  • colour

This is all handled, still, within that “image” argument definition, and we allow a decimal (ie. “.”) delimiter be the way a user separates their integer values (where an opacity value becomes “0.” + [integerValue]).

As an example take a look at the example …

Emoji Borders and Backgrounds Shapes Tutorial

Onto yesterday’s Emoji Borders and Backgrounds Text Justification Tutorial we add some consideration of SVG shape creations into the mix of the Emoji Borders and Backgrounds work, starting just with the PHP tool, at this stage, and just considering …

… to start off with, and feeding off yesterday’s …

  • width=[designatedPxWidth] and height=[designatedPxHeight] … and/or …
  • image=[someImageUrl] (width and height)

… breakdown as to how a user can define a box of interest, as a great “line in the sand” for us to work around with this new “Shapes functionality”. It’s an interfacing job, for tomorrow, getting parents to work with this “image” argument based way a user can define these shapes, including a “noimage” option that uses an image’s width and height (to help out with the shape definition) but does not display that image.

Along the way we also mildly rearrange PHP code for inline_svg.php‘s live run so as to allow for more than one user text to be added via justification prefixing methodologies.

Emoji Borders and Backgrounds CSS Styling Tutorial

It was some time ago now that we said …

… via a new “text” argument arranged for the PHP and in readiness for some more aesthetic improvements in the display side of things with our emoji borders and backgrounds

Well, what gives? Eh, wot’s up ‘guv? Yes, indeed … all we can say is …

We got sidetracted.

… and applying spell checker to get around an expression that amuses us …

We got sidetracked.

So, “being ‘guv” … eh, wot … today we’re having a posting catch up with all the parents and PHP tool child allowing for some CSS styling to be a possibility with the web applications around the theme of “Emoji Borders and Backgrounds”, onto yesterday’s Emoji Borders and Backgrounds in Canvas Tutorial.

And so wotwhat’s the go with styling in SVG “land”? Is SVG classy? It’s not that much different to HTML and CSS, in that “style” elements are allowed, and SVG allows you to define a “class” attribute for SVG elements, so that’s kind of classy … eh, wot, ‘guv?! Thanks to this great link for the heads up on this.

We decided to allow for our changed inline_svg.php PHP tool’s PHP tool live run to understand all arguments coming in whose name ends in CSS …

<?php

$svgmiddle='';

foreach ($_GET as $name=>$val) {
if (strpos(strtolower('' . $name . '~'), 'css~') !== false) {
if ($svgmiddle == '') {
$svgmiddle="
<style type=\"text/css\" >
<![CDATA[
." . strtolower($name) . " { " . str_replace(';;',';',trim(str_replace('+',' ', urldecode($_GET[$name]))) . ';') . " }
]]>
</style>

";
} else {
$svgmiddle=str_replace("<![CDATA[", "<![CDATA[
." . strtolower($name) . " { " . str_replace(';;',';',trim(str_replace('+',' ', urldecode($_GET[$name]))) . ';') . " } ", $svgmiddle);
}
}
}

foreach ($_POST as $name=>$val) {
if (strpos(strtolower('' . $name . '~'), 'css~') !== false) {
if ($svgmiddle == '') {
$svgmiddle="
<style type=\"text/css\" >
<![CDATA[
." . strtolower($name) . " { " . str_replace(';;',';',trim(str_replace('+',' ', urldecode($_POST[$name]))) . ';') . " }
]]>
</style>

";
} else {
$svgmiddle=str_replace("<![CDATA[", "<![CDATA[
." . strtolower($name) . " { " . str_replace(';;',';',trim(str_replace('+',' ', urldecode($_POST[$name]))) . ';') . " }
", $svgmiddle);
}
}
}

?>

… to add the means by which the SVG’s optional “style” elements be populated, leaving it up to the various parents to inform the users of the possibilities here.

Emoji Borders and Backgrounds in Canvas Tutorial

Extending yesterday’s Emoji Borders and Backgrounds in Image Map Grid Tutorial‘s “Emoji Border and Background” horizons, today, we take an interest in three associated HTML “graphic” elements …

Can we start with SVG+XML data and get to populate CANVAS data via IMG data via data URIs? Well, not everything works, but enough works to have a lot of what you’d want to do “in this neck of the woods” be possible.

<?php

var svg = document.querySelector('svg');
var img = document.querySelector('img');
var canvas = document.querySelector('canvas');

// get svg data
var xml = new XMLSerializer().serializeToString(svg);
//alert(xml);

// make it base64
var svg64 = ''; //btoa(xml);
var b64Start = ''; //'data:image/svg+xml;base64,';

// set it as the source of the img element
img.onload = function() {
// draw the image onto the canvas
canvas.getContext('2d').drawImage(img, 0, 0);

if ($bemb != "") {
echo "\n img.src = '" . $bemb . "'; \n";

We’d like to thank html – Drawing an SVG file on a HTML5 canvas – Stack Overflow for the idea that we expand on with our “proof of concept” canvas_svg.php‘s live run web application (calling our changed inline_svg.php PHP tool’s PHP tool live run).

Emoji Borders and Backgrounds in Image Map Grid Tutorial

Further to yesterday’s Emoji Borders and Backgrounds in Inhouse Slideshow Deployment Tutorial were you around when we presented Image Map Grid Styling Email Share Tutorial?

Well, it’s our “second cab off the rank” regarding a parent idea to oversee our current PHP tool idea for Emoji Borders and Backgrounds.

Anything new? Well, yes, quite a big concept too. With our PHP tool, today, we are allowing it, for a PHP parent (today’s changed imagegridmap.php‘s live run), to fill in a

<?php

var tableih='<table id=oneandonly style=\"' + tw + th + 'background:" . $opprefix . "URL(" . backg("' + indu + '") . ");background-repeat:no-repeat;background-size:' + tcover + ';' + tcss + '\"><tbody id=oneandonlytbody style=\"width:100%;' + 'height:100%;\"></tbody></table>';

?>

… background image (to a table element) data URI with mimetype image/svg+xml and base64 encoding via …

<?php

function backg($indef) {
global $prebimg, $bimg, $udirname, $poemoji;
$udirnameprebimg=$udirname . $prebimg;
if (isset($_GET['iurl'])) {
$udirnameprebimg=str_replace('+',' ',urldecode($_GET['iurl']));
} else if (isset($_POST['iurl'])) {

}
if (isset($_GET['emoji'])) {

list($wdt, $hgt) = getimagesize($udirnameprebimg);
if ($wdt > 0 && $hgt > 0) {
//echo $udirname . "1:" . $hgt;
return file_get_contents($udirname . "../inline_svg.php?asbackground=y&imaXge=" . urlencode($udirnameprebimg) . "&width=" . (-20 + $wdt) . "&height=" . (-20 + $hgt) . "&insvg=" . str_replace('+','',urldecode($_GET['emoji']))) . '),URL(' . $indef;

$poemoji='<input type=hidden id=emoji name=emoji value="' . str_replace('+','',urldecode($_POST['emoji'])) . '"></input>';
list($wdt, $hgt) = getimagesize($udirnameprebimg);
if ($wdt > 0 && $hgt > 0) {
return file_get_contents($udirname . "../inline_svg.php?asbackground=y&imaXge=" . urlencode($udirnameprebimg) . "&width=" . (-20 + $wdt) . "&height=" . (-20 + $hgt) . "&insvg=" . str_replace('+','',urldecode($_POST['emoji']))) . '),URL(' . $indef;
} else {

}
} else {
return $indef;
}
}

?>

Interesting idea, don’t you think?

It meant a division of two “threads” of modus operandi (possible by “overriding” the PHP echo function into an inhouse “ourecho” (wrapper style of) function), now, for our changed inline_svg.php PHP tool’s PHP tool live run

<?php

$asbkg=false;
$whati='image';

if (isset($_GET['asbackground']) || isset($_POST['asbackground'])) {
$asbkg=true;
$whati='youllneverfindthis';
} else {
header('Content-type: image/svg+xml');
}

// In here are echo"ourecho" codeline calls to construct the SVG+XML

function ourecho($inh) {
global $asbkg;
if ($asbkg) {
echo "data:image/svg+xml;base64," . base64_encode('<svg' . explode('<svg', explode('</svg>', $inh)[0])[1] . '</svg>');
} else {
echo $inh;
}
}


?>

And don’t you just love “the two steptwo thread jive”!

The deployment aspects to yesterday’s Emoji Borders and Backgrounds in Inhouse Slideshow Tutorial “Inhouse Slideshow” PHP functionality are in our sights today … happy holidays!

“Inhouse Slideshow” functionality can not avoid the serverside PHP (ie. the changed index.php PHP clone “original” and clone) in all its aspects, and so we still need …

  • the kind of clunky “many PHP clones” approach we talked about at Inhouse Slideshow Design Exif Korn Shell Deployment Tutorial for PHP serverside deployment (via the changed job.ksh Korn Shell script parent creator of and “asker” of therealchange.ksh file copying Korn Shell deployer command line script) aspects to “Inhouse Slideshows” (and as you can see with today’s tutorial animated GIF picture), but, as we introduced with this round of such … but as of yesterday …

Emoji Borders and Backgrounds in Inhouse Slideshow Tutorial

Continuing on from yesterday’s Emoji Borders and Backgrounds via Emoji Menu Tutorial and harkening back to Emoji Borders and Backgrounds Image Text Parent Tutorial‘s …

… the functionalities that would be “cool” at the HTML/Javascript/CSS parent side, and then work out how to implement similar functionality, as possible, in SVG, and if possible, we should be able to pass arguments over to the “PHP tool” to eventually code it to be standalone to help other “parenting arrangements”.

… today’s “theme” concerns the first of those other “parenting arrangements” mentioned above, our PHP for Inhouse Slideshow presentation display options …

… the new “Emoji Border Slideshow” display option above calling into play our inline_svg.php PHP tool’s live run (“Are we there yet, as a tool, I mean … Mum … Dad … anyone?”) web application.

And in so doing, to use an Emoji Menu methodology of selecting your emoji border decoration is “right up your street, Inhouse Slideshow supervisor”.

You will find, examining the changed PHP code representative “first cab off the rank” and “guinea pig” live run that we introduce a non-existant external Javascript call …


<script type='text/javascript' src='/inhouse_slideshow.js' defer></script>

… into the mix. Why? Well, perhaps, first off, you should read some history of this “Inhouse Slideshow” project over time at Inhouse Slideshow Temporary Unzip Tutorial and then see that this “external Javascript lark” could be better for a way to “future proof” the venture, with some improvements being changeable through one (into your chosen Document Root folder, wherever that may be (that is what the leading “/” infers)) external Javascript codefile rather than a myriad number of identical PHP codefiles.

Emoji Borders and Backgrounds via Emoji Menu Tutorial

Emoji Borders and Backgrounds via Emoji Menu Tutorial

On this macOS MacBook Air we’re used to …


control-command-space

… bringing up an Emoji Menu from which an emoji can be selected and placed wherever the cursor had been placed before that menu display. That could be …

  • on an address bar where the cursor is placed
  • in a Javascript prompt window that is focussed

… both scenarios (amongst many others, no doubt) of which we will be interested with our current Emoji Borders and Background web application project. Today’s work develops our PHP tool ahead of its supervisory web application, and so we are interested in the first scenario above, as far as testing it goes with our changed underlying inline_svg.php PHP tool live run web application.

The argument “text” is already catered for from yesterday but the nature of the data this $_GET[‘text’] might contain had not catered for …

  • unicode data (via Emoji Menus) … but rather had catered for
  • Javascript call of String.fromCodePoint([comma separated list of HTML Decimal Entity(s)]);

… only, as of yesterday’s Emoji Borders and Backgrounds Image Text PHP SVG Tutorial. As you would probably concur, yesterday’s setup was quite user unfriendly, as so many of us now are used to those Emoji Menus being used to fill in your emoji data requirements.

The main gist of the PHP code changes goes …

<?php

$innards='';
$preinnards='';

function ingp($m) { // thanks to https://pretagteam.com/question/how-do-i-convert-unicode-special-characters-to-html-entities
global $innards, $preinnards;

}, $innards);
$preinnards=htmlentities($entity);
$innards='';
}
}

// And then later we change ...

ingp($innards);
}
if ($preinnards == '') {

}
// rest of if block code uses $preinnards as SVG text innerHTML ... but UTF-16 Surrogate pair scenarios can fail
