Page Image Manipulator 2

Recommended Posts

Hi, I have uploaded a new version to Github that fully supports PW 2.6+ with its new naming scheme.

The package now ships with two Pim versions, the older one, called Pim, that can be used until PW 2.5 stable, and the new one, Pim2 that should be used with PW 2.6+

So, if you start a new site with PW 2.6+, simply install Pim2 only!

If you have upgraded PW to 2.6 on an existing site with lots of image variations, you

  1. should install Pim2 additionally to the older one, (do not uninstall it yet!)
     
  2. then you should start to change your API calls in your templates like the following explanation

.

here is a code line from the older Pim:

$image = $image->pimLoad($prefix)->watermarkText($txt, 75)->setQuality(80)->pimSave();

.

To start with smooth change from Pim to Pim2, you can change it to this:

// use the old Pim to remove the PimVariations with old naming scheme:
$image->pimLoad($prefix)->removePimVariations();

// in the copied original code line, only change pimLoad to pim2Load, note the number 2 ! in the new start method !
$image = $image->pim2Load($prefix)->watermarkText($txt, 75)->setQuality(80)->pimSave();

.

This way you have some control on which parts the new creation may take effect, e.g. on a small site you can change all API calls at once and drop caches if exists. On bigger sites you may start at one template / page first, and add more changes later.

.

Regardless of this, you can safely let the call to the older removePimVariations() method stay in your code for a while, as they do not interact with the newer one. After a while, when you do not see any of those old filenames in your assets/files folders, you can remove those lines from your code and also uninstall the older Pim.

All other methods than pimLoad / pim2Load are completly identical and can be seen here in the API

Hello! How is going?
I am confused how to update pim2 from PW (or really anywhere). Currently I got both pim1 and pim2 installed, but only pim1 is shown in ProcessWireUpgrade with the version 2.1 while pim2 is 2.7. Is there a proper way to handle this?

Hi.

There are no plans to update Pim2. And if it will be updated, the version number from Pim1 will be bumped up, so that it shows up in the update modules list. (Pim2 is handled as submodule of Pim, Pim1)

To be correct:

Install pim, what installs pim1, go to modules / site, install pim2 and use pim2load().

It needs a rewrite someday for recent PW versions (2.8+ & 3.0+) :)

Hi @horst, I tried out this module today and it's nice, thanks. :)

But the installation process and the PIM1/PIM2 thing was clear as mud to me - I got it worked out in the end but I don't understand why the module is set up that way.

I get the need for different module versions according to which PW version you are running, but couldn't PIM1 and PIM2 be separate modules be in separate GitHub repos and you just install the one you want? Or better - could there just be a single module that checks the PW version number and uses the right code for that version? That way pimLoad() and pimSave() wouldn't have to be renamed and choosing/installing/using the module would be simpler for the user.

@Robin S it was due to an needed upgrade from Pim1 to Pim2 because of changes in the naming conventions for images in PW > 2.6.?.

At this time Pim1 already was installed and used in many sites. When people upgraded their PW version in those sites, they could not / cannot simply change Pim1 with Pim2. There was a manually action in changing API calls in template files needed. This was / is the reason for this weird behave.

For the simply case of first install of the module, I can use a PW version detection of course, but that wasn't the problem. The problem was / is, that in prior PW versions with use of Pim1:

  • i must used the Pim1 as first / only module, to get the people informed about update changes via upgrade-module(s)
  • must ommit an automated change from old naming convention to the new one, because sites possibly would break down if I would raise a need to recreate every image (!)

So, yes, I was and I'am very unhappy with this situation. If someone has a better solution, please tell me.

-------

BTW, with the CroppableImage3 I run into something similar:

Croppable3 isn't recognized by the widely used upgrade-module from Ryan, so people don't get informed about updates of it. I believe, many sites are running a version prior to 0.9.17. Everytime someone updates an older PW version site to a newer version, they run into a bug that was already fixed a year ago in version 0.9.17. People than always report that they just upgraded from x to PW > 3.0.31* (or similar), and the module now wouldn't work anymore. :( But it is already fixed. They all need to do a manual update, but how can I inform them? The updater should do so, but doesn't do. :(

@horst, I can see how that upgrade would be difficult to do gracefully. Will post back if I have any ideas.

Regarding CroppableImage3 and the ProcessWireUpgrade module: I think the reason why the upgrades module doesn't see available updates for CI3 is due to the module class name that is showing in the modules directory. The class name shown is "CroppableImage3" but I'm not sure where that comes from because it isn't actually a class name that is used in the modules (correct me if I'm wrong). Did you enter that manually? Or maybe it comes from the name of the GitHub repo?

When the upgrades module queries the modules directory it is looking for the classnames...

  • FieldtypeCroppableImage3
  • InputfieldCroppableImage3
  • ProcessCroppableImage3

...but it doesn't find a match for any of these, therefore they are left out of the table of upgradable modules.

Maybe it would be best to follow the example of several of the other fieldtype modules, where the primary name of the module would be FieldtypeCroppableImage3 even though it auto-installs two other modules.

The reason it wasn't detected was, that no module was in the root directory of the module, but all each of the three modules resides in its own subdirectory.

      ---- INITIAL POST FROM 2019-05-25 ----
      I wanted to let you know that I am currently working on a new ProcessWire module that fully integrates the Snipcart Shopping Cart System into ProcessWire. (this is a customer project, so I had to postpone the development of my other module GroupMailer).
      The new module SnipWire offers full integration of the Snipcart Shopping Cart System into ProcessWire.
      Here are some highlights:
      simple setup with (optional) pre-installed templates, product fields, sample products (quasi a complete shop system to get started immediately) store dashboard with all data from the snipcart system (no change to the snipcart dashboard itself required) Integrated REST API for controlling and querying snipcart data webhooks to trigger events from Snipcart (new order, new customer, etc.) multi currency support self-defined/configurable tax rates etc. Development is already well advanced and I plan to release the module in the next 2-3 months.
      I'm not sure yet if this will be a "Pro" module or if it will be made available for free.
      I would be grateful for suggestions and hints!
      (please have a look at the screenshots to get an idea what I'm talking about)

      Update 31.7.2019: AdminBar is now maintained by @teppo. Modules directory entry has been updated, as well as the "grab the code" link below.
      ***
      Latest screencast: http://www.screencas...73-ab3ba1fea30c
      Grab the code: https://github.com/teppokoivula/AdminBar
      ***
      I put this Adminbar thingy (from here: http://processwire.c...topic,50.0.html) to modules section and to it's own topic.
      I recorded quick and messy screencast (really, my first screencast ever) to show what I have made so far. You can see it from here: http://www.screencas...18-1bc0d49841b4
      When the modal goes off, I click on the "dark side". I make it so fast on screencast, so it might seem a little bit confusing. Current way is, that you can edit, go back to see the site (without saving anything), continue editing and save. After that you still have the edit window, but if you click "dark side" after saving, then the whole page will be reloaded and you see new edits live.
      I am not sure if that is best way: there are some strengths in this thinking, but it is probably better that after saving there shouldn't be a possibility to continue editing. It might confuse because then if you make edits, click on dark side -> *page refresh* -> You lose your edits.
      ***
      When I get my "starting module" from Ryan, I will turn this into real module. Now I had to make some little tweaks to ProcessPageEdit.module (to keep modal after form submits). These probably won't hurt anything:
      if($this->redirectUrl) $this->session->redirect($this->redirectUrl); if(!empty($_GET['modal'])) $this->session->redirect("./?id={$this->page->id}&modal=true"); // NEW LINE else $this->session->redirect("./?id={$this->page->id}");   and...
      if(!empty($_GET['modal'])) { $form->attr('action', './?id=' . $this->id . '&modal=true'); } else { $form->attr('action', './?id=' . $this->id); // OLD LINE }

      Jumplinks for ProcessWire
      Release: 1.5.54
      Composer: rockett/jumplinks
      Jumplinks is an enhanced version of the original ProcessRedirects by Antti Peisa.
      The Process module manages your permanent and temporary redirects (we'll call these "jumplinks" from now on, unless in reference to redirects from another module), useful for when you're migrating over to ProcessWire from another system/platform. Each jumplink supports wildcards, shortening the time needed to create them.
      Unlike similar modules for other platforms, wildcards in Jumplinks are much easier to work with, as Regular Expressions are not fully exposed. Instead, parameters wrapped in curly braces are used - these are described in the documentation.
      Under Development: 2.0, to be powered by FastRoute
      As of version 1.5.0, Jumplinks requires at least ProcessWire 2.6.1 to run.
      View on GitLab
      Download via the Modules Directory
      Read the docs
      Features
      The most prominent features include:
      Basic jumplinks (from one fixed route to another) Parameter-based wildcards with "Smart" equivalents Mapping Collections (for converting ID-based routes to their named-equivalents without the need to create multiple jumplinks) Destination Selectors (for finding and redirecting to pages containing legacy location information) Timed Activation (activate and/or deactivate jumplinks at specific times) 404-Monitor (for creating jumplinks based on 404 hits) Additionally, the following features may come in handy:
      Stale jumplink management Legacy domain support for slow migrations An importer (from CSV or ProcessRedirects) Feedback & Feature Requests
      I’d love to know what you think of this module. Please provide some feedback on the module as a whole, or even regarding smaller things that make it whole. Also, please feel free to submit feature requests and their use-cases.
      Note: Features requested so far have been added to the to-do list, and will be added to 2.0, and not the current dev/master branches.
      Open Source

      Jumplinks is an open-source project, and is free to use. In fact, Jumplinks will always be open-source, and will always remain free to use. Forever. If you would like to support the development of Jumplinks, please consider making a small donation via PayPal.
      Enjoy! :)

      I've spent the last while experimenting with srcset implementation - and PageimageSrcset is the result:
      PageimageSrcset
      Provides configurable srcset and sizes properties/methods for Pageimage.
      Overview
      The main purpose of this module is to make srcset implementation as simple as possible in your template code. It does not handle images rendered in CKEditor or similar fields.
      For an introduction to srcset and sizes, please read this Mozilla article about responsive images.
      Pageimage::srcset()
      // The property, which uses the set rules in the module configuration $srcset = $image->srcset; // A method call, using a set rules string // Delimiting with a newline (\n) would also work, but not as readable $srcset = $image->srcset("320, 480, 640x480 768w, 1240, 2048 2x"); // The same as above but using an indexed/sequential array $srcset = $image->srcset([ "320", "480", "640x480 768w", "1240", "2048 2x", ]); // The same as above but using an associative array // No rule checking is performed $srcset = $image->srcset([ "320w" => [320], "480w" => [480], "768w" => [640, 480], "1240w" => [1240], "2x" => [2048], ]); // Use the default set rules with portrait images generated for mobile/tablet devices $srcset = $image->srcset(true); // Return the srcset using all arguments $srcset = $image->srcset("320, 480, 640x480 768w, 1240, 2048 2x", [ "portrait" => "320, 640", ]); // The set rules above are a demonstration, not a recommendation! Image variations are only created for set rules which require a smaller image than the Pageimage itself. On large sites this may still result in a lot of images being generated. If you have limited storage, please use this module wisely.
      Portrait Mode
      In many situations, the ratio of the image does not need to change at different screen sizes. However, images that cover the entire viewport are an exception to this and are often the ones that benefit most from srcset implementation.
      The main problem with cover images is that they need to display landscape on desktop devices and portrait when this orientation is used on mobile and tablet devices.
      You can automatically generate portrait images by enabling portrait mode. It is recommended that you use this in combination with Pageimage::focus() so that the portrait variations retain the correct subject.
      The generated variations are HiDPI/Retina versions. Their height is determined by the portrait ratio (e.g. 9:16). Variations are always generated, regardless of whether the original image is smaller. Upscaling is disabled though, so you may find that some variations are actually smaller than they say they are in their filename.
      The sizes attribute should be used when portrait mode is enabled. Pageimage::sizes will return (orientation: portrait) and (max-width: {maxWidth}px) 50vw by default, which handles the use of these images for retina devices. The maximum width used in this rule is the largest set width.
      Pageimage::sizes()
      There is no option to configure default sizes because in most cases 100vw is all you need, and you do not need to output this anyway as it is inferred when using the srcset attribute. You can use the method for custom sizes though:
      // The property $sizes = $image->sizes; // Returns 100vw in most cases // Returns '(orientation: portrait) and (max-width: {maxWidth}px)50vw' if portrait mode enabled // A method call, using a mixture of integer widths and media query rules // Integer widths are treated as a min-width media query rule $sizes = $image->sizes([ 480 => 50, "(orientation: portrait) and (max-width: 640px)" => 100, 960 => 25, ]); // (min-width: 480px) 50vw, (orientation: portrait) and (max-width: 640px) 100vw, (min-width: 960px) 25vw // Determine widths by UIkit 'child-width' classes $sizes = $image->sizes([ "uk-child-width-1-2@s", "uk-child-width-1-3@l", ]); // (min-width: 640px) 50vw, (min-width: 1200px) 33.33vw // Determine widths by UIkit 'width' classes $sizes = $image->sizes([ "uk-width-1-2@m", "uk-width-1-3@xl", ]); // (min-width: 960px) 50vw, (min-width: 1600px) 33.33vw // Return the portrait size rule $sizes = $image->sizes(true); // (orientation: portrait) and (max-width: {maxWidth}px) 50vw // The arguments above are a demonstration, not a recommendation! Pageimage::render()
      This module extends the options available to this method with:
      srcset: When the module is installed, this will always be added, unless set to false. Any values in the formats described above can be passed. sizes: Only used if specified. Any values in the formats described above can be passed. uk-img: If passed, as either true or as a valid uk-img value, then this attribute will be added. The srcset attribute will also become data-srcset. Please refer to the API Reference for more information about this method.
      // Render an image using the default set rules echo $image->render(); // <img src='image.jpg' alt='' srcset='{default set rules}'> // Render an image using custom set rules echo $image->render(["srcset" => "480, 1240x640"]); // <img src='image.jpg' alt='' srcset='image.480x0-srcset.jpg 480w, image.1240x640-srcset.jpg 1240w'> // Render an image using custom set rules and sizes // Also use the `markup` argument echo $image->render("<img class='image' src='{url}' alt='Image'>", [ "srcset" => "480, 1240", "sizes" => [1240 => 50], ]); // <img class='image' src='image.jpg' alt='Image' srcset='image.480x0-srcset.jpg 480w, image.1240x640-srcset.jpg 1240w' sizes='(min-width: 1240px) 50vw'> // Render an image using custom set rules and sizes // Enable uk-img echo $image->render([ "srcset" => "480, 1240", "sizes" => ["uk-child-width-1-2@m"], "uk-img" => true, ]); // <img src='image.jpg' alt='' data-uk-img data-srcset='image.480x0-srcset.jpg 480w, image.1240x640-srcset.jpg 1240w' sizes='(min-width: 960px) 50vw'> // Render an image using portrait mode // Default rule sets used: 320, 640, 768, 1024, 1366, 1600 // Portrait widths used: 320, 640, 768 // Original image is 1000px wide // Not possible to use portrait mode and custom sets or portrait widths in render() // Sizes attribute automatically added echo $image->render(["srcset" => true]); // <img src='image.jpg' alt='' srcset='image.320x569-srcset-hidpi.jpg 320w, image.640x1138-srcset-hidpi.jpg 640w, image.768x1365-srcset-hidpi.jpg 768w, image.jpg 1024w' sizes='(orientation: portrait) and (max-width: 768px) 50vw'> Configuration
      To configure this module, go to Modules > Configure > PageimageSrcset.
      Set Rules
      These are the default set rules that will be used when none are specified, e.g. when calling the property: $image->srcset.
      Each set rule should be entered on a new line, in the format {width}x{height} {inherentwidth}w|{resolution}x.
      Not all arguments are required - you will probably find that specifying the width is sufficient for most cases. Here's a few examples of valid set rules and the sets they generate:
      Set Rule Set Generated Arguments Used 320 image.320x0-srcset.jpg 320w {width} 480x540 image.480x540-srcset.jpg 480w {width}x{height} 640x480 768w image.640x480-srcset.jpg 768w {width}x{height} {inherentwidth}w 2048 2x image.2048x0-srcset.jpg 2x {width} {resolution}x How you configure your rules is dependent on the needs of the site you are developing; there are no prescriptive rules that will meet the needs of most situations. This article gives a good overview of some of the things to consider.
      When you save your rules, a preview of the sets generated and an equivalent method call will be displayed to the right. Invalid rules will not be used, and you will be notified of this.
      Portrait Mode
      Set Widths
      A comma limited list of widths to create HiDPI/Retina portrait variations for.
      Crop Ratio
      The portrait ratio that should be used to crop the image. The default of 9:16 should be fine for most circumstances as this is the standard portrait ratio of most devices. However, you can specify something different if you want. If you add a landscape ratio, it will be switched to portrait when used.
      Any crops in the set rules ({width}x{height}) are ignored for portrait mode variations as this ratio is used instead.
      UIkit Widths
      If your website theme uses UIkit, you can pass an array of UIkit width classes to Pageimage::sizes to be converted to sizes. The values stored here are used to do this. If you have customised the breakpoints on your theme, you should also customise them here.
      Please note that only 1- widths are evaluated by Pageimage::sizes, e.g. uk-width-2-3 will not work.
      Remove Variations
      If checked, the image variations generated by this module are cleared on Submit. On large sites, this may take a while. It makes sense to run this after you have made changes to the set rules.
      Image Suffix
      You will see this field when Remove Variations is checked. The value is appended to the name of the images generated by this module and is used to identify variations. You should not encounter any issues with the default suffix, but if you find that it conflicts with any other functionality on your site, you can set a custom suffix instead.
      Debug Mode
      When this is enabled, a range of information is logged to pageimage-srcset.
      PageimageSrcsetDebug.js is also added to the <head> of your HTML pages. This will console.log a range of information about the images and nodes using srcset on your page after a window.onresize event is triggered. This can assist you in debugging your implementation.
      The browser will always use the highest resolution image it has loaded or has cached. You may need to disable browser caching to determine whether your set rules are working, and it makes sense to work from a small screen size and up. If you do it the other way, the browser is going to continue to use the higher resolution image it loaded first.
      UIkit Features
      This module implements some additional features that are tailored towards UIkit being used as the front-end theme framework, but this is not required to use the module.
      Installation
      Download the zip file at Github or clone the repo into your site/modules directory. If you downloaded the zip file, extract it in your sites/modules directory. In your admin, go to Modules > Refresh, then Modules > New, then click on the Install button for this module. ProcessWire >= 3.0.123 is required to use this module.
