Animated GIF Creation Localhost Text Emoji Slide Tutorial

A day or so before yesterday’s Animated GIF Creation Slide Annotating Tutorial we intimated with …

… where we have started coding for emojis as well …

… that animated GIF slides could successfully contain unicode emojis. At that stage, unusually for this whole (very long running) Animated Gif Creator project, the functionality …

worked in our RJM Programming public domain environment … but …
did not work back at our local MAMP Apache/PHP/MySql web server environment

Huh?! Yes, for the public domain usage we were making use of the brilliant Google Pagespeed Insights functionality, thanks, (but) which does not work for localhost URLs, pretty understandably!

We had time to mull over this, and extending yesterday’s Animated GIF Creation Slide Annotating Tutorial‘s use of the Scribble and Annotating Inhouse Helper, which uses an HTML canvas element as its graphics modus operandi, we thought we might be onto a grinner (if you’ll pardon the poor attempt at Clayton‘s Cockney slang). We could get the ball rolling similarly to yesterday, with …

<?php echo ”
var dtval=tval; if (tval.trim() == '+' || (document.URL.indexOf('http://localhost') == 0 && dtval.replace('>','<').indexOf('<') == -1 && (containsNonLatinCodepoints(dtval) || hasEntities(dtval)))) { var useyourwords=''; if (canvw == '') { canvw=document.getElementById('mycanvas').toDataURL('data/jpeg', 10); } if (tval.trim() != '+') { var coldelim=tval.split('`'); if (eval('' + coldelim.length) > 1 && eval('' + coldelim[0].trim().length) > 0 && dtval.split(coldelim[0])[1].indexOf(' ') == -1) { cfcol=coldelim[1]; if (eval('' + coldelim.length) > 2) { cbcol=coldelim[2]; } if (eval('' + coldelim.length) > 3) { cffam=coldelim[3]; } if (eval('' + coldelim.length) > 4) { cfsz=coldelim[4]; } } dtval=tval.split('`')[0]; useyourwords='&thewords=' + encodeURIComponent(dtval) + '&cbcol=' + encodeURIComponent(cbcol) + '&cfcol=' + encodeURIComponent(cfcol) + '&cffam=' + encodeURIComponent(cffam) + '&cfsz=' + encodeURIComponent(cfsz); resetyes(); tval='+'; dtval='+'; } tval=canvw; document.getElementById(tid.replace(/^slideshow1$/g,'slideshow')).value=canvw; var hw=eval(500 - eval(tid.replace('slideshow',''))) canvwo.push(window.open('/HTMLCSS/user_of_signature_signature.htm?slide=' + tid.replace(/^slideshow1$/g,'slideshow') + useyourwords, '_blank', 'top=' + eval(screen.height - hw) + ',left=' + eval(screen.width - hw) + ',width=' + hw + ',height=' + hw)); }
“; ?>

… in our changed animated GIF creator PHP tutorial_to_animated_gif.php inhouse animated GIF creator web application, pulling along with it yesterday’s …

… “using ` being able to change as per user requirement” ideas. Then, at the other end one intervention wrapper can have us creating canvas text which is mapped back to an Animated GIF slide data URI content textbox back at the Animated GIF Creator web application …

… with our changed link’s user_of_signature_signature.htm Scribble and Annotating Helper web application.

You may be wondering why this is worth the effort? Well, we highly recommend using this Animated GIF Creator logic in a local web server (eg. MAMP) environment, in terms of speed, and flexibility involving other Open Source products like ImageMagick and Ffmpeg which can help you out.

… and …

improved the functionality of “text” slides by allowing the user to use \n to indicate they would like to place a line feed in the resultant slide “text” look …
function bsn(dv) { var newdv=dv, twf=25, addon=25; var bsnds=dv.split(String.fromCharCode(92) + 'n'); if (eval('' + bsnds.length) <= 1) { return dv; } addon=Math.floor(eval(65 / eval('' + bsnds.length))); //alert(dv + ' 00:' + newdv + ' ...

With our animated GIF creator, last referenced with Ffmpeg Shelling Peas Tutorial, we wanted to nuance the way the ImageMagick and GD effects could operate …

they being only applicable to the entire animated GIF output image … before today’s work which makes it so that …
optionally they can be turned on or off for individual animated GIF slides

… thereby allowing more flexibility for the user, we’re hoping.

Feel free to try our changed animated GIF creator PHP tutorial_to_animated_gif.php inhouse animated GIF creator web application which now features the additional “slide blurb additional snippet” …

Please note double click toggles the negation of any GD rotations etcetera for this slide only and will become pale yellow here when in negated status, and that a 4x click on first selection reverses logic to be only 2x click selections from then on for a pale orange slide textbox background.

The non-mobile platforms have that useful wooooorrrrllllddd, the “onhover wooooorrrrllllddd” (to be precise) that can be a great partner for Javascript Ajax methodologies.

Lemon curry?! Animated dropdown?! What gives? Well, it’s not “shelling peas”, yet!

Yes, there is another “framework” step forward we wanted to implement before the peas. And yes, no surprises there, the “framework” work relates to adding functionality to our main dropdown. We’re adding a layer of functionality we’re going to refer to as “animated dropdown”. It amounts to …

dropdown (ie. select element) … for non-mobile …
has size attribute equal to the number of option elements it contains
logic wise, because our non-nothing option innerText_s have equalled option value_s (if you Javascript trim() the option innerText, that is), we have the opportunity to start taking more notice of the …
<?php echo ”
function process(tv, tvo) { var newval=''; var ourtv=tvo.value; if (tv != '') { ourtv=tvo.options[tvo.selectedIndex].innerText.trim(); } if (origval == '') { origval=document.getElementById('mydefopt').title; } if (tv == '') { document.getElementById('mainspan').innerHTML=document.getElementById('mydefopt').title; } else { document.getElementById('mydefopt').title=ourtv; //tv; document.getElementById('mainspan').innerHTML=document.getElementById('mydefopt').title; document.getElementById('schoices').value=''; } newval=document.getElementById('mydefopt').title; //alert('origval,newval=' + origval + ' ' + newval); if (newval != origval) { origval=newval; wentfrom(origval, newval); } else { origval=newval; } }
“; ?>
… option innerHTML as above, meaning …

we can set up Javascript code facilitating the animated feel of some option innerHTML looks that are taken notice of as selected via …

Global variables arranged via each “verb” involved … for today’s “proof of concept” we add one extra Pandoc “Text to Rich Text” option, for now, before the flood of peas arrives …

Concat demuxer

First, make a text file.

Then, run ffmpeg :

ffmpeg -f concat -i list.txt -c copy out.mp4

… and for File API browsing (with our, once again, tweaked inhouse client_browsing.htm) there will be a delay, deriving the file path in “second call PHP”. We handle this by writing two new Javascript functions …

… available to call from child iframes via parent.takeoneoff(); (from voiceover.php second PHP call) and parent.organizefilenamesize(files[ij].name, files[ij].size); (from client_browsing.htm) respectively, to facilitate a progress cursor on the submit button to remind the user we’d like more time. Along the way, too, we found …

And so, onto yesterday’s Ffmpeg Improved Windows Media Browsing Tutorial feel free to see this in the changed voiceover.php PHP (we’d want you to download to a local MAMP Apache web server’s Document Root folder and which you can run that PHP there).

Ffmpeg Improved Windows Media Browsing Tutorial

Yesterday’s Ffmpeg Mux Video and Audio Windows Media Browsing Tutorial taught us a lesson, as a side issue, that what we said when we presented Animated GIF Creation on Windows MAMP via PDF Tutorial …

No matter how we tried, we could not get a Windows command line command like …

forfiles /P "[PathToFileBestGuess]" /S /M "[FileBaseName]" /C "cmd /c echo @path@fsize" | find "[FileSizeInBytes]"

… to work out a file path when supplied a file base name and a file size and you call as above with starting folders. That works well (for deriverability (if that is a word!)) in the “cmd” window but not when called under the auspices of PHP exec or shell_exec. It could be that you lose a lot of a Windows user environment when asking PHP to do some operating system work.

… was “only partially” the story. We found out that that ” | find ” command piping could cause problems on Windows MAMP using shell_exec or exec to do some operating system functionality. But before your enthusiasm oozes over the edges, Windows “forfiles” is still very hard to get working with PHP shell_exec or exec, even using PHP to perform that ” | find ” filtering of results.

However, on revisiting the issue in the changed voiceover.php PHP (we’d want you to download to a local MAMP Apache web server’s Document Root folder and which you can run that PHP there) there were dual purpose motivations going on, for us, because our changed animated GIF creator PHP tutorial_to_animated_gif.php (that if you download to MAMP would best go to Document Root PHP/animegif folder along with the wonderful GIFEncoder.class.php … thanks) inhouse animated GIF creator web application and the changed PDF parts to animated GIF creation helper php_calls_pdfimages.php (also a standalone proposition) PHP code could be fixed up at the same time, with a new PHP ourshell_exec function interventional code snippet up at the top …

<?php
function ourshell_exec($onea, $twoa = NULL, $threea = NULL) { $folder=''; $pattern=''; $size=''; $filesa=[]; if (PHP_OS =='WINNT' || PHP_OS =='WIN32' || PHP_OS =='Windows' || (strpos(('~@!' . $onea), '~@!forfiles /P "') !== false && strpos(('~@!' . $onea), '/M "') !== false && strpos(('~@!' . $onea), 'find "') !== false)) { $folder=explode('"', explode('forfiles /P "', $onea)[1])[0]; // . substr(DIRECTORY_SEPARATOR . DIRECTORY_SEPARATOR, 0, 1); if (7 == 7) { $folder=explode('"', explode('forfiles /P "', $onea)[1])[0]; // . substr(DIRECTORY_SEPARATOR . DIRECTORY_SEPARATOR, 0, 1); $pattern=explode('"', explode('/M "', $onea)[1])[0]; $size=explode('"', explode('find "', $onea)[1])[0]; $thiscmd=trim(explode(" | find ", $onea)[0]); if (strpos($pattern, ' ') === false) { $thiscmd=str_replace('/M "' . $pattern . '"', '/M ' . $pattern, $thiscmd); } if (strpos($folder, ' ') === false) { $thiscmd=str_replace('/P "' . $folder . '"', '/P ' . $folder, $thiscmd); } if (strpos($thiscmd, '"cmd /c ') !== false && substr($thiscmd,-1,1) != '"') { $thiscmd.='"'; } if (strpos($thiscmd, "/P C:\\ ") !== false) { if (strpos($thiscmd, "/P C:\\ ") !== false) { if (strpos($pattern, " ") === false) { $thiscmd="DIR C:\\" . $pattern . " /S /-C"; } else { $thiscmd="DIR \"C:\\" . $pattern . "\" /S /-C"; } } } //file_put_contents('xxx.xxx',file_get_contents('xxx.xxx'). "\n" . '' . $size . ' ' . $thiscmd); $nofind=shell_exec($thiscmd . ' 2> nul'); //file_put_contents('xxxx.xxxx',file_get_contents('xxxx.xxxx'). "\n" . '' . $size . ' ' . $nofind); //exit; $findings=explode("\n", $nofind); $bitbefore=''; for ($ifindgs=0; $ifindgs<sizeof($findings); $ifindgs++) { if (strpos(str_replace("\r","",$findings[$ifindgs]), 'Directory of ') !== false) { $bitbefore=explode('Directory of ', str_replace("\r","",$findings[$ifindgs]))[1] . "\\"; } if (strpos((str_replace("\r","",$findings[$ifindgs]) . '~'), $size . '~') !== false) { return str_replace('~','',str_replace($size . '~', '', (str_replace("\r","",$findings[$ifindgs]) . '~'))); } else if (strpos((str_replace("\r","",$findings[$ifindgs]) . ''), $size . ' ') !== false) { //file_put_contents('xxxxx.xxxxx',$bitbefore . explode($size . ' ', (str_replace("\r","",$findings[$ifindgs]) . ''))[1]); return $bitbefore . explode($size . ' ', (str_replace("\r","",$findings[$ifindgs]) . ''))[1]; } } if ($folder == "C:\\") { return ''; } } // more code // as per usual // stays here ... } return shell_exec($onea, $twoa, $threea); }
?>

… where we substitute in Windows DIR C:\ /S /-C thinking in place of forfiles (via shell_exec minus the ” | find ” piping, that is).

You know it’s “Intranet feely land”?

You look out the train window (tee hee) and see macOS racing through their usual routine.

Of course you’ll pick the buffet car containing the rice bubbles ahead of the vegemite corn flakes?!

But do we need to reiterate that in “Intranet feely land” you’ve got your macOS typose of work not suiting “arch Windows” methodologies? Take the case of …

At least, with macOS MAMP there is the excellent command line “file” we can use to show information about some potential input files you could use in this, so far, user unfriendly, “first draft” version of the PHP.

… to the beach, would be nice … but we digress. Well, in any case, we asked Google (not via the “arch Window”) does windows have the equivalent of linux file command” and got to the helpful What is the equivalent to the Linux File command for windows? – Super User, thanks, and then ended up at the really useful third party “file.exe” for (non-arch) Windows usage and proceeded with it, working off Ffmpeg Mux Video and Audio Media Browsing Tutorial, to start being able to develop this “reveal” details/summary arrangement in either macOS or Windows MAMP environments, that “ffmpeg” voiceover command, which normally works a lot better than …

I command thee mux, hey you, with audible you, over yonder, by dale and meadow be, yea!

… when it occurred to us we could turn the base filename parts of those “file_.exe” reports into links that when clicked mapped those clicked files into place into the “ffmpeg” command being developed above (as alternative input file designator idea to browsing or div contenteditable=true typing ways), in the changed voiceover.php PHP (we’d want you to download to a local MAMP Apache web server’s Document Root folder) and which you can run that PHP there.

And so, we reckon the work day got worth it!

… reign supreme collecting their media file specification information in the changed voiceover.php PHP (we’d want you to download to a local MAMP Apache web server’s Document Root folder) and which you can run that PHP there.

The previous work of Animated GIF Creation Install Paths Tutorial‘s thread of blog postings has been a great help with this ffmpeg “Intranet feeling” integration work we use, around here, in conjunction with macOS or Windows operating system MAMP Apache local web server environments.

We’ve got another “Intranet feeling” PHP web application “first draft” for you today. The reason we’re opting for “Intranet feeling” (ie. we’re asking you to download the voiceover.php PHP to a local MAMP Apache web server and run the PHP there from its Document Root folder) is that we want to further explore the brilliant …

… we got inspired to try via Mux Video and Audio from another Video and FFMPEG mux video and audio (from another video) – mapping issue … thanks and thanks … to add audio to a video stream from two different sources.

At least, with macOS MAMP there is the excellent command line “file” we can use to show information about some potential input files you could use in this, so far, user unfriendly, “first draft” version of the PHP.
