Emoji Borders and Backgrounds in Canvas Tutorial

Extending yesterdayโ€™s Emoji Borders and Backgrounds in Image Map Grid Tutorialโ€˜s โ€œEmoji Border and Backgroundโ€ horizons, today, we take an interest in three associated HTML โ€œgraphicโ€ elements โ€ฆ

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 youโ€™d want to do โ€œin this neck of the woodsโ€ 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,';

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

Well, itโ€™s our โ€œsecond cab off the rankโ€ 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 (todayโ€™schanged imagegridmapโšซphpโ€˜s liveโœ‚run), to fill in a โ€ฆ

<?php

function backg($indef) {

if (isset($_GET['iurl'])) {

$udirnameprebimg=str_replace('+',' ',urldecode($_GET['iurl']));

Interesting idea, donโ€™t you think?

It meant a division of two โ€œthreadsโ€ of modus operandi (possible by โ€œoverridingโ€ the PHP echo function into an inhouse โ€œourechoโ€ (wrapper style of) function), now, for ourchanged inline_svgโšซphp PHP toolโ€™s PHPโœ‚tool live run โ€ฆ

<?php


$asbkg=false;

$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>');

โ€ฆ the functionalities that would be โ€œcoolโ€ 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 โ€œPHP toolโ€ to eventually code it to be standalone to help other โ€œparenting arrangementsโ€.

โ€ฆ todayโ€™s โ€œthemeโ€ concerns the first of those other โ€œparenting arrangementsโ€ mentioned above, our PHP for Inhouse Slideshow presentation display options โ€ฆ

โ€ฆ the new โ€œEmoji Border Slideshowโ€ display option above calling into play our inline_svgโšซphp PHP toolโ€™s liveโœ‚run (โ€œAre we there yet, as a tool, I mean โ€ฆ Mum โ€ฆ Dad โ€ฆ anyone?โ€) web application.

And in so doing, to use an Emoji Menu methodology of selecting your emoji border decoration is โ€œright up your street, Inhouse Slideshow supervisorโ€.

You will find, examining thechanged PHPโšชcode representativeโœ‚โ€œfirst cab off the rankโ€ and โ€œguinea pigโ€ live run that we introduce a non-existant external Javascript call โ€ฆ



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

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

Emoji Borders and Backgrounds via Emoji Menu Tutorial

On this macOS MacBook Air weโ€™re used to โ€ฆ



control-command-space

โ€ฆ 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 โ€ฆ

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

โ€ฆ both scenarios (amongst many others, no doubt) of which we will be interested with our current Emoji Borders and Background web application project. Todayโ€™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 ourchanged underlying inline_svgโšซphp PHP tool liveโœ‚run web application.

The argument โ€œtextโ€ is already catered for from yesterday but the nature of the data this $_GET[โ€˜textโ€™] might contain had not catered for โ€ฆ

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

โ€ฆ only, as of yesterdayโ€™s Emoji Borders and Backgrounds Image Text PHP SVG Tutorial. As you would probably concur, yesterdayโ€™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 โ€ฆ

<?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;

$entity = preg_replace_callback('/[\x{80}-\x{10FFFF}]/u', function ($m) {

$char = current($m);

$utf = iconv('UTF-8', 'UCS-4', $char);

return sprintf("&#x%s;", ltrim(strtoupper(bin2hex($utf)), "0"));

}, $innards);

$preinnards=htmlentities($entity);

$innards='';

}

}



// And then later we change ...

if (isset($_GET['insvg'])) {

$innards=str_replace('+','',urldecode($_GET['insvg']));

if (trim(str_replace(',','',str_replace('0','',str_replace('1','',str_replace('2','',str_replace('3','',str_replace('4','',str_replace('5','',str_replace('6','',str_replace('7','',str_replace('8','',str_replace('9','',$innards)))))))))))) != '') {

ingp($innards);

}

if ($preinnards == '') {


$preinnards='&#' . str_replace(',',';&#',$innards) . ';';

}

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