Animated GIF Creator Video Share Tutorial
It’s one thing to use macOS (via Big Sur, on this MacBook Air) MAMP local web server to create animated GIFs and (derived) videos via an inhouse PHP web application, but another thing to go and share those videos out into the big wide online woooorrrrlllldddd, on top of yesterday’s Animated GIF Creator Video Revisit Tutorial‘s progress.
Sending emails via macOS Big Sur command line mechanisms is still possible, we found, via postfix via Gmail relay mechanisms, but you need to allow your Gmail account “accept less secure apps” to have anything happen with these email attempts. But once this is fixed you can use any (installed) of …
- sendmail
- mailx
… software (command) conduits, and use “mailq” and the macOS Console desktop application and perhaps /var/log logs to monitor and debug.
So, what are the steps to get macOS postfix command line email sending working? We consulted this excellent link, thanks, and came up with, at least for us …
$ sudo vi /etc/postfix/sasl_passwd
Add the line:
[smtp.gmail.com]:587 username@gmail.com:password
Save and close the file. Your Gmail password is stored as plaintext, so make the file accessible only by root:
$ sudo chmod 600 /etc/postfix/sasl_passwd
$ sudo vi /etc/postfix/main.cf
# Add to bottom
relayhost = [smtp.gmail.com]:587
smtp_sasl_auth_enable=yes
smtp_sasl_password_maps=hash:/etc/postfix/sasl_passwd
smtp_sasl_mechanism_filter = AUTH LOGIN
smtp_sasl_security_options =
smtp_use_tls=yes
smtp_tls_security_level=encrypt
$ sudo postmap /etc/postfix/sasl_passwd
$ sudo postfix reload
- # In our Gmail account we went to the “?” help section and entered “allow less secure” to get to links whereby we (temporarily) started “allowing less secure” apps …
- # Monitoring and testing involved …
$ echo -e "Content-Type: text/html\nFrom: rmetcalfe@rjmprogramming.com.au\nto: rmetcalfe15@gmail.com\ncc: rmetcalfe@rjmprogramming.com.au\nSubject: First Date ps-ef world.php Report at `date`\n\n<html><head><style> tr:nth-child(even) {background-color: #CCC } tr:nth-child(odd) {background-color: #FFF } </style></head><body><h1>First Date ps-ef world.php Report at `date`</h1></body></html>" | $ sendmail -t -f rmetcalfe15@gmail.com
$ mailq
$ mailq
$ cd PHP/animegif
$ cat video.webm | uuencode 'video.webm' | mailx -s "Video video/webm from RJM Programming" rmetcalfe15@gmail.com
$ mailq
$ mailq
- # Given all this allowed us to send emails via Gmail relay postfix methodologies from a local web server command line, in our Gmail account we went to the “?” help section and entered “disallow less secure” to get to links whereby we went back to “disallowing less secure” apps
Why the “[]” bracketing of “smtp.gmail.com”? No MX mail server records become involved, that’s why. Take a look at today’s animated GIF presentation going over these steps above.

We hope you realize that our changed tutorial_to_animated_gif.php inhouse Animated GIF Creator (helped out by a changed emailhtml.php inhouse email creator helper serverside PHP web application) can be accessed …
- in that public RJM Programming mode of use above … but even better can be …

… one reason being that we do not want to install the wonderful ffmpeg (command line video creation tool) on the RJM Programming domain, but, in macOS, here with MAMP, we are quite happy to live with the Homebrew (Terminal application’s) install …
brew install ffmpeg
… to open a whole new woooooorrrrlllllddd of video creation opportunities using this MAMP local web URL …
HTTP://localhost:8888/PHP/animegif/tutorial_to_animated_gif.php# Animated GIF Creator on MAMP local web server
And so, onto yesterday’s Animated GIF Creator PDF Last Reveal Tutorial we decided to revisit video creation parts of our inhouse Animated GIF Creator on this MacBook Air. We needed to reinstall ffmpeg, and we show that in today’s animated GIF tutorial picture and also created the “video.mov” video below, in the process …
… we tweaked out of “video/mp4” ffmpeg created videos thinking towards “video/webm” or “video.mov” ffmpeg created videos that suit the “few frames but spaced out video” we wanted to achieve for all practical purposes, that “video/mp4” playing too fast for us to see anything much but the first and last slide …

Animated GIF Creator PDF Last Reveal Tutorial
As a web application programmer we like buttons. There are “buttons” and there are buttons. Yes, there is an HTML button element, and it and the input type=button element render as that part of a webpage most recognizable to users the world over. You click or tap this button and something usually happens.
But we also enjoy “Emoji Buttons” for we graphically challenged programmers. Using an emoji text and graphic can make span elements or p elements or lots of other HTML elements that have an innerHTML property, be like a very succinct button like entity, also appreciated around here because it takes up so little webpage “real estate”.
And so onto yesterday’s Animated GIF Creator PDF Order Tutorial we set about, today, “revealing” any enduring animated GIF and/or PDF created during a previous session, using Emoji Buttons as the email/SMS sharing action buttons.
We say “revealing” because, like the way “Emoji Buttons” save webpage “real estate”, so can the use of the HTML5 details/summary element combination. It is in that summary “enduring” header part of that combination we can place some “Emoji Buttons”. You will (once you start creating and sharing animated GIFs and/or PDFs) see from our changed tutorial_to_animated_gif.php inhouse Animated GIF Creator (helped out by a changed emailhtml.php inhouse email creator helper serverside PHP web application) that we place three Emoji Buttons …
- 📟 SMS (Animated GIF or PDF) Limited relevance period (ie. no data URIs involved, so rely on an absolute URL whose content might change or start not to exist down the track) … via “a” “sms:” link click/tap
- 📧 Email (Animated GIF or PDF) Limited relevance period (ie. no data URIs involved, so rely on an absolute URL whose content might change or start not to exist down the track) … via “a” “mailto:” link click/tap
- 📧 Email (Animated GIF or PDF) Enduring relevance (ie. data URIs involved, so do not rely on any absolute URL whose content might change or start not to exist down the track) … via PHP mail function means of sending email with HTML attachment containing the relevant Animated GIF or PDF
Yes, “Emoji Buttons” can have their size controlled but not by the usual CSS width and height properties, but by the CSS font-size property. Here is the new Javascript function that those Emoji Button “onclick” logic points to …

Animated GIF Creator PDF Order Tutorial
Order becomes an interesting subject to us today regarding the PDF conversions possible in amongst the Animated GIF creating of yesterday’s Animated GIF Creator PDF Share Tutorial.
That is because we may have some advanced users out there that want that possibility of differentiating the data of …
- animated GIF … containing all features asked for, in totality … from the chance for the user to have any of the PDF conversion option sets below …
- PDF … one of …
- no PDF conversion
- full PDF conversion … with the user choices regarding raw image content and title and watermarking and ImageMagick and GD modifiers
- light PDF conversion … with the user choices regarding just raw image content (the only option out of these last three available before today’s work)
- medium PDF conversion … with the user choices regarding just ImageMagick and GD modifiers
… perhaps as a “before and after” tool regarding presentations, maybe?
No dropdowns used here (enforcing an order), just the user’s order in which they choose to select the “PDF conversion” option from the ImageMagick dropdown (in relation to other selections) determining how and when this PDF conversion occurs in the workflow through to creating the animated GIF with our changed tutorial_to_animated_gif.php inhouse Animated GIF Creator serverside PHP web application. Just remember to select PDF Conversion as early as possible to do that “light PDF conversion” option above and last thing if you are interested in “full PDF conversion” (where you can create PDF documents with the bells and whistles ImageMagick and GD modifiers can offer) and today’s tutorial picture is an example of “medium PDF conversion” (when we ordered our settings by first Grayscale, second PDF conversion and last title and watermarking options). Clicking or tapping the ImageMagick link can get the user to the Javascript popup window where they might define the email or SMS recipient for that PDF conversion data file download.

To share yesterday’s Animated GIF Creator PDF Conversion Tutorial PDF data formatted image slides (and then onto an animated GIF) would be a step forward, wouldn’t you say?
What sharing conduits do we code for? We always intended …
- email … but as the day wore on trying to get the usage to work on mobile and non-mobile we decided to relinquish our wish to not have to create a user specific enduring (until that same browser type and user combination share) PDF document for the user request … mainly to get mobile email downloads to be friendly … and so this opened the door for …
- SMS … to access that enduring PDF as a URL in the SMS message (that becomes a link for the recipient)
… the email methodology used being that “midair feeling” Ajax/FormData approach in our changed tutorial_to_animated_gif.php inhouse Animated GIF Creator serverside PHP web application …

Up to yesterday’s Animated GIF Creator Slide Specific Application Tutorial the recent progress had us …
- knowing the good places to intervene between the original slide image data being read in and the animated GIF slide output … and …
- involvement of ImageMagick … so, today, these two help us down the path to …
- adding PDF as an output format possibility, in addition to the animated GIF and other ideas floated as output formats
… with our changed tutorial_to_animated_gif.php inhouse Animated GIF Creator serverside PHP web application.
We have more “reliability work” and “email sharing work” to go after today’s start, but it primarily called on ImageMagick command line’s talent for a command like …
convert /tmp/imtmp0*.*[gGmMiI]* /tmp/imtmp000.pdf
… to “concatenate” into the one output PDF file (called “/tmp/imtmp000.pdf”) the slides, arranged by our code into that “/tmp/imtmp0*.*[gGmMiI]*” (file specification) arrangement above. Yes, we meant “convert” above, as “mogrify” (batch work) appears not to be able to perform this task.
We hope you stay the course!

Animated GIF Creator Slide Specific Application Tutorial
It’s all fine and good improving on the ImageMagick and GD and Exif functionality modifications like with yesterday’s Animated GIF Creator Exif Rotation Compensation Tutorial, but in reality, if you are going to start creating animated GIFs to explain a process, you are going to want to apply these “slide modifiers” on a slide by slide basis, rather than enforcing a “whole of animated GIF slide set” paradigm, as for the last few days worth of work.
And so, we decided to do what we often do, “sliding in” more functionality (chortle, chortle). We tend to want to …
- start with hardcoded text (or element) … somewhere … today it happens to be in an HTML span element that once involved just …
<span id="smyim"></span>
… and used to get filled, Javascript DOM wise, when needed via …
document.getElementById('smyim').innerHTML='ImageMagick switches: '; // and yes, it remains that way even now, but read on ...
- add intelligence (quite often that being onclick logic(s)) to that hardcoded element via …
<span id=smyim title=Application onclick=applyto(); style=cursor:pointer;text-decoration:underline;></span>
- that serves the purpose, as the user clicks/taps it (alerted to that fact, perhaps, because we underline the element and add an appropriate cursor when hovering over it (plus a title)), of calling Javascript …
function applyto() {
var huhto=prompt('Apply ImageMagick and/or GD to which slides, in comma separated list, counting starting with 1? Defaults to applying to all slides. Comma delimit. Negatives mean all but. Ranges can be specified. For example ... 2,4-7,9', document.getElementById('appliedto').value);
if (huhto == null) { huhto=''; }
if (huhto.trim() == '') {
document.getElementById('appliedto').value='';
document.getElementById('smyim').title='Application';
} else {
document.getElementById('appliedto').value=huhto.trim();
document.getElementById('smyim').title=huhto.trim();
}
}
- to glean an (often times out of the normal workflow of the web application) informational piece of data, interactively, from the user, via a Javascript prompt popup
So that’s the clientside of this work … “alerting the user to the existance of the functionality” you might say.
And then there’s “the application” of that nuanced user requirement. And that’s where the “inhouse ‘our’ prefix to wrapper function name paradigms” come in handy. We introduced “blanket” functionality thoughts via this approach, and so to “partially undo” that thinking, we make the “our” prefix conditional, as is available to us with our changed tutorial_to_animated_gif.php inhouse Animated GIF Creator serverside PHP web application (helped out by a changed exif_rotation_check.php inhouse Exif detector PHP helper), as per …

We use these “new abilities” better explaining “the abscence or otherwise of Exif checking”, and the implications of that in the animated GIF creator woooooorrrrrrlllllddd, contrasting the first two slides, showing one with “No Exif checking” (the bad old days) versus “With Exif checking” (the renaissance of liberated thinking in the South South East woooorrrrrlllldddd) in today’s animated GIF presentation.
Get the picture?!

Animated GIF Creator Exif Rotation Compensation Tutorial
The recent couple of days of work like yesterday’s Animated GIF Creator GD Transformations Interfacing Tutorial have given us “rotation functionality” tools to counteract the unusual effects Exif …
Exchangeable image file format (officially Exif, according to JEIDA/JEITA/CIPA specifications) is a standard that specifies the formats for images, sound, and ancillary tags used by digital cameras (including smartphones), scanners and other systems handling image and sound files recorded by digital cameras.
… can have converting mobile device camera created images into animated GIFs via our changed tutorial_to_animated_gif.php inhouse Animated GIF Creator PHP web application.
But with some photos it’s there in the photo’s metadata information letting the future user know what orientation the camera of that mobile device was in as you took the photo. In order to help our animated GIF creator, the first slide image is scoured for Exif metadata and if found, a suitable rotation correction can be applied to the slides there and then. In order to scour for Exif metadata we needed to write a exif_rotation_check.php inhouse Exif detector PHP helper.

ImageMagick Vignette Primer Tutorial
Continuing on with the ImageMagick batch processing “mogrify” ideas of yesterday’s ImageMagick Batch Image Conversion Affine Transformation Tutorial and the “vignette” image editing ideas of Gimp Vignette Primer Tutorial, as below, today, we took some pet photos with an iPad’s Camera app and shared them off the Photos app via two Mail sharing option emails containing seven attachments each. Using an iPad, the JPEG “jpg” output files were too big for our inhouse Animated GIF Creator PHP web application to handle, and so to perform the …
- animated GIF presentation, off these downloaded email photo attachments … and along the way …
- quality adjusted them (yes, “mogrify” does not stuff JPG to JPG conversions, and we used “mogrify” -quality 20% switch here) … and …
- rotate them 180 degrees (“mogrify” uses switches -affine -1,0,0,-1,0,0 -transform +repage here) … and …
- vignette 50% (“mogrify” uses switch -vignette 50 here)
… on the way to compiling into an animated GIF image, and we turned to ImageMagick again, using its affine transformation talents, along with its awesome vignetting talents …
… where the last two dropdown options will be similar, the last showing the input image into ImageMagick can be an animated GIF that is truely treated like an animated GIF.
By the way, should you be interested in photo orientation off a mobile device camera, have a read of PHP Exif Image Information Revisit Tutorial.

Gimp Vignette Primer Tutorial
The last time we talked about the miraculous, redolent and amazing image editor called Gimp am sure there was someone in a shower … it stands to reason … and one of those showerers, surely, would have been singing The Gimp Song … and if not … why not? … but we digress … anyway we had the Gimp Transparency Primer Tutorial as shown below go into some image transparency issues with Gimp.
In today’s tutorial we make use of a great tutorial (even so far as with direct quotes below) called Add a Vignette to a Photograph with GIMP (thanks) to try a photographic technique called vignetting on one of the photographs we added, recently, into the mix of those of the Custom Header Image mix at this blog … specifically the one of Nala, the dog, on the door ledge. Need to warn you here and now that if there was the time all over again, it would be better achieved that second time around, but this is not the point with learning, but rather getting some starting point with a great “product” like Gimp, and trying it yourself, once you have a method. It boils down to:
- Open Gimp graphical editor application
- File->Open … pick your image file
- Layer->New Layer (we’ll call “Vg”) … pick Foreground Colour
- In the Layers dialog, click on your “Vg” layer to select it, and select Soft light from the “Mode” drop-down box
- Right click on your “Vg” layer and go to Add Layer Mask. In the dialog that pops up, you want “Initialise Layer Mask to” set to “White (full opacity)”. Click “Add”
- Below Opacity bar select Link icon next to Eye icon, which will already be showing
- Use the freeform select tool (press F to bring this up) and draw a selection somewhere around the primary point of interest in your photo
- Use your bucket tool (Shift+B) and click within the selection to fill it
- Deselect your selection with Select->None
- Go to Filters->Blur->Gaussian Blur. In the dialog that comes up, you want “Radius” set to a very large amount; a tenth of the longest edge of the photo is not too much
- Click on your “Vg” layer to select it (if it isn’t already selected), and then slide the opacity slider towards the right until the effect is subtle enough. Our (ever so subtle) example of Nala, in the tutorial, used an opacity of about 66%
- Click Export button in two windows (NB. this overwrites the image file, so if this is not desirable, export to a different image file name and/or type)
Here is an image comparison link.
As with most Gimp ideas, jump in and give it a go, as you’ll find your own ways and means of using this great product … am pretty sure.

Gimp Transparency Primer Tutorial
Here is a tutorial that adds to a previous Gimp Layers Primer Tutorial as shown below, and gives you more insight into the massive possibilities of using a sophisticated image editor and use layers with various amounts of transparency, especially suited to use with png image files.
Today’s tutorial where we construct a Birthday Card that needs tweaking for the words in front to be seen a bit more clearly, by making the image behind a bit more transparent, changes the transparency of a single image via:
- Open Gimp graphical editor application
- File->Open Layers … pick your image file
- If Layers window not showing, make it show via Windows->Layers – Brushes
- Below Opacity bar select Link icon next to Eye icon, which will already be showing
- Change Opacity bar setting to a value of Transparency (100% is Opaque, 0% is Transparent) that suits … today we do 70%
- File->Export
- Click Export button in two windows (NB. this overwrites the image file, so if this is not desirable, export to a different image file name and/or type)

Gimp Layers Primer Tutorial
Here is a tutorial that gives you an insight into the massive possibilities of using a sophisticated image editor and use layers with various amounts of transparency, especially suited to use with png image files.
Transparency (or its obverse, opacity) can be used to have the one image achieve several “ends” (ie. purposes). Although it is a bit of a clumsy example in the tutorial, you can see that the technique can be used for artistic purposes … often called “Photoshopping” (named after the more famous, and also brilliant, rival product, Photoshop).
Lots of those classic “Photoshopping” techniques can be achieved in Gimp, and some other tutorials at this blog touch on that.
Am sure you can imagine what the concept of a layer is with regard to image manipulation. Within Gimp, for beginners not used to this concept, you find yourself underestimating and underplaying what can be achieved with the various layers of a multi-layered image. In simplistic terms each layer has the functionality in Gimp to be treated as a whole new image, and this is the best way to think of it when trying to achieve what you want to achieve with Gimp.
