Image Conversions via PHP GD Overlay Reveal Tutorial

Image Conversions via PHP GD Overlay Reveal Tutorial

Around here, we have two words we like to approach the topic of “web design”, where it meets “practicality”, with …

• reveal
• overlay

And so, onto yesterday’s Image Conversions via PHP GD Multiple Actions Tutorial‘s progress with our Image Conversions via PHP GD web application we were keen to think that an “overlay” concept could be part of the workings, at the image creation stage of the web design. Supposing you have a set of images that go to make up the whole, we can use the new “Merge” option as per …

… we found was most feasible with PNG input image files, with transparency.

And then, onto yesterday’s Image Conversions via PHP GD Multiple Actions Tutorial‘s progress with our Image Conversions via PHP GD web application we were keen to think that an “reveal” concept (a bit like a cartoon, perhaps) could be part of the workings, at the image creation stage of the web design. Supposing you have a set of images that go to make up the whole, we can use the new “Merge” option as per …

… we found was most feasible with …

• PNG input image file(s) … self made or source from a free source such as Pixabay, thanks …
• cut up via Gimp‘s …
  1. Selection Tools -> Free Select … and …
  2. Edit -> Clear … and …
  3. File -> Export As… -> .png (set “Save color values from Transparent Pixels” on)
• open PNG in Paintbrush and File -> Save As… -> JPEG
• use “Merge” option of Image Conversion via GD web application

And then, at least with our MAMP local Apache web server PHP version we can also offer …

• crop … nominate a colour in images to crop via, and gets a look in with today’s animated GIF tutorial picture
• transparent … nominate a colour in images to make transparent

… additional functionalities in the changed convert_wildcard.php‘s image conversion PHP web application.

Image Conversions via PHP GD Multiple Actions Tutorial

We’ve waited a while preparing for today’s release of “multiple actions” functionality onto yesterday’s Image Conversions via PHP GD Transformations Tutorial. From how we see it we had a choice of two approaches to delivering this new functionality …

• start using select (ie. dropdown) element multiple attribute approach … but, especially because we are separating GD “Filters” into one dropdown and “Transformations” into another, we think it would be better to …
• start prefixing ✔ (✔ tick) emoji to selected action(s) to apply to any images involved in the conversions

The ✔ (✔ tick) emoji was enough for us, yet we wanted to indicate to the user the order of actions they’ve entered. To do this we were helped out by Javascript sort methodology used in …

<?php echo ”

function sortsel(insel) {
var sv=insel.value;
var optsa=insel.innerHTML.split('</option>');
var sopta=optsa.sort();
var newih='';
for (var ioj=0; ioj<sopta.length; ioj++) {
newih+=sopta[ioj] + '</option>';
}
insel.innerHTML=newih;
insel.value=sv;
}

“; ?>

… accepting the GD “Filter” dropdown object as a parameter. But how is that going to help when “action” titles will just determine the sort order? Well, the select (ie. dropdown) element here is made up of …

<?php echo ”

<option value=\”action_desc\”>Action Desc</option>

“; ?>

… parts where we started defining the first two this way …

<?php echo ”

<option class=\”opt000\” value=\”\”>Image Filter …</option><option class=\”opt001\” value=\” \”>Image Filter Ask Arguments …</option>

“; ?>

… and then changed our dropdown onchange event logic supplementing a new “whenmulti” total picture data member that is now maintained …

<?php echo ”

var nextcls=2;

function zoomsame(tvo, tvv) {
var tv=tvo.value;
var rest='';

  … making a MAMP curl usage such as …

curl "http://www.rjmprogramming.com.au/convert_wildcard.php?command=wh*.*g*+-q+76+-negate+.jpeg"

  Please issue command …
  open http://www.rjmprogramming.com.au/temphtml.html
  … to see results. Omit the open word for Windows. You have up to the next minute to do this.

  … and a quick witted user will copy and paste that open http://www.rjmprogramming.com.au/temphtml.html quickly enough to see a webpage offering image download functionalities

… in the changed convert_wildcard.php‘s image conversion PHP web application.

Did you know?

With that last “rjmprogramming.com.au” curl scenario it occurs to us, you could optionally do a multiple command (or use type ahead buffer on Windows) like …


curl "http://www.rjmprogramming.com.au/convert_wildcard.php?command=wh*.*g*+-q+76+-negate+.jpeg" ; open http://www.rjmprogramming.com.au/temphtml.html


… for a 99% chance of success without having to worry about the “too quick” copying and pasting in less than a minute caper! Blurb output will correct you if temphtml.html is not the go.

Or think procedural scripting where Windows has *.bat batch files and macOS or Linux have shells like sh or bash or csh or ksh (our favourite, called Korn Shell). A scheduled procedural crontab command action part could be a Korn Shell one liner like …


ksh -c 'curl "http://www.rjmprogramming.com.au/convert_wildcard.php?command=wh*.*g*+-q+76+-negate+.jpeg" ; open http://www.rjmprogramming.com.au/temphtml.html'


Then a Korn Shell script we’ll call “daily.ksh” on macOS or Linux could contain …


#!/bin/ksh
curl "http://www.rjmprogramming.com.au/convert_wildcard.php?command=wh*.*g*+-q+76+-negate+.jpeg"
open http://www.rjmprogramming.com.au/temphtml.html
exit


… then, thinking macOS or Linux, make it (perhaps too) executable via …


chmod 777 daily.ksh


… and make happen via …


./daily.ksh

… into the mix. We add this select element “dropdown” within the HTML form method=POST action=”Here’s looking at you kid” arrangement. Initially it gets assigned just an ID attribute, with no NAME attribute, which is an ideal arrangement when functionality is optional. And so, if the user chooses a real “filter” here it gets assigned an appropriate NAME attribute as per the PHP’s Javascript dropdown onchange event logic …

… PHP code that may be familiar looking to readers of our recent PDF Image and Text Nodes Windows Files Tutorial thread of blog postings. Feel free to try the changed convert_wildcard.php PHP web application you can also try below.

Image Conversions via PHP GD Primer Tutorial

Regular readers at this place will know about our admiration for ImageMagick and its command line (“convert” for macOS and Linux and “magick.exe” for Windows) image conversion functionality. Even so, ImageMagick is not capable of …


convert filespec*.*g* *.jpeg


… type of image conversion, in bulk, kind of processing (which Gimp offered with its sadly departed Bimp conversion software in the past). But tailored PHP use of the GD (image manipulation) library, helped out by (good ol’) PHP glob, is!

And so, we’ve written a “proof of concept” converter that you can run at the RJM Programming domain, but we’d recommend for use with an Apache/PHP local web server like MAMP is! (Two in one blog posting is a record … is!)

Get into MAMP, and you might want to download convert_wildcard.php PHP source code to MAMP’s Document Root folder. Else, try it here or below …
