Page Image Manipulator 1

Recommended Posts

Ok I have it corrected but still it doesn't work. No error, no new image created.

$p = wire("pages")->get(1111);
echo $p->image->url;
$img = $p->image;
$pim = $img->pimLoad("bright")->contrast(100)->brightness(100)->pimSave();
echo "<img src='$pim->url'/>";

hhm, very mysterious. When I use your code I get a new image!

I assume you have get the latest version of the module, tried a new install already?

What do you get when you use:

$p = wire("pages")->get(1111);
$img = $p->image;

echo '<p>' . $img->url .'</p>';
echo '<p>' . $img->width(240)->url .'</p>';   // does the imageSizer work with that image?

echo '<pre>';
	var_dump($img->pimLoad("bright")->getImageInfo());  // what is the output here
echo '</pre>';

No there's no image created and it silently fails, means code after doing the image doesn't get executed at all.

I tried locally and it works, so it's the server I'm working on... although it's php 5.3 and GD 2...

@soma: does the imageSizer work with the images?

$img->width(240) or $img->size()

It doesn't do anything. :)

Ok strange, now it works, and I only added some echo "test" inside the getPageImageManipulator() and uploaded. 

So I think I got when testing added a exit() there and haven't uploaded the module when removing it. Darn. :) Thanks for your time.

This is kinda fun... 

Q: How could I easily replace the original pageimage keeping same filename?

Q: How could I easily replace the original pageimage keeping same filename?

with a pageimage loaded into the {Pageimage} {Manipulator} you are not able to overwrite the original!

You have to use the {Image} {Manipulator} manually with a filename. Here you can do everything you want, - or the opposite: you alone are fully responsible for _all_ actions, ;-)

$pim = $wire->modules->get('PageImageManipulator')->imLoad($imageFilename, $options);  // here it is used imLoad = image manipulator instead of page image manipulator

If you do not specify an alternate filename or outputFormat with the options array, the sourcefile loaded into the IM is overwritten by default!

Note: if you overwrite your original image, you wipe out all EXIF-data, whereas all IPTC-data is kept!

Hey Soma, it looks like you are building a visual Photo-Editor based on PW.  cool!

Horst, would you consider adding a resize mode that adds a colored or transparent padding instead of distorting the image? Something like this:

Greetings,

Horst, would you consider adding a resize mode that adds a colored or transparent padding instead of distorting the image? Something like this:

That would be great!

I can't even count how many client photos I have had to edit manually in this way so they look correct in my galleries.

Thanks,

Matthew

Hi diogo, if you believe it or not, I have thought about this allready. And I have something like this in an old image lib of mine. I will look at that code and port it to the IM.

I think best way is to define dimensions of a canvas in that the previous created image is centered. That way one can get only the horizontal or only the the vertical bars, or surrounding ones.

Great!

I think it could be even more complex than that. Ideally it would have these options:

  • width
  • height
  • background-color (including the possibility of rgba if possible)
  • x-position
  • y-position

Does it make sense like this?

@diogo: width & height & BG as rgba is ok!

But for what is x- and y-position?

I have thought one want to center it into the canvas.

If you think it make sence to position out of the center, I think it could be better to use the north, northwest, center, etc position and a $padding (I would prefer in percent), that would be most consistent way with other methods.

What do you think?

hoi, there are now two 'unplanned' additions in the Version 0.0.5:
 
canvas($width, $height, $bgcolor, $position, $padding)

  • $width = mixed, associative array with options or integer, mandatory!
  • $height = integer, mandatory if $width is integer!
  • $bgcolor = array with rgb or rgba, - default is 255, 255, 255
  • $position = one out of north, northwest, center, etc, - default is center
  • $padding = integer as percent of canvas length, - default is 0

unsharpMask($amount=100, $radius=0.5, $threshold=3) // its the same like the method in Photoshop,
credit goes to: Torstein Hønsi for the unsharp mask algorithm (created in 2003 - p h p U n s h a r p M a s k)!

..., can create better results than the default stepResize!

Is there a auto level or auto adjust function in gd like with imagemagick?

Share this post

So there's a ton of functions and filter but auto-levels http://www.imagemagick.org/script/command-line-options.php#auto-level there's nothing in GD? ... :D

Other then in imagemagick, i don't see a ton of functions and filters in there :D

I think to autoadjust something there is always a portion of guessing with it - or 'out-rider' pixels that screw up or down the autoadjusted result into false directions.

I never use such tools without a manually visually control. Also with captureOne and photoshop I do not use those with batch editing.

Hi Horst, your plugin is great and the canvas addition is superb ;-)

However ... I have there a little problem with the canvas addition. 

The call of

child->image2->pimLoad('wh',true)->canvas(195,193,array(0,0,0,0.0),"centered",0)->pimSave()->url;

returns me the image with a black border. I want it transparent. Is there something I missed?

TIA

Hi Henning,

I think you have the wrong param for opacity. PHP.net says:

function imagecolorallocatealpha

  param alpha:
      A value between 0 and 127. 0 indicates completely opaque while 127 indicates completely transparent.

Please try with

child->image2->pimLoad('wh', true)->canvas(195, 193, array(0, 0, 0, 127), "centered", 0)->pimSave()->url;

EDIT:

@Henning: I have noticed that the common way to define a rgba color is 0-255 for R, G and B and a float value between 0 and 1 for the alpha channel (opacity). 0 is transparent and 1 is opaque.

I think it is better to use the common way with float 0-1 as param and convert it internally to suite the need of the GD-lib.

The change will go into the module version 0.0.8 and I will release it later this weekend.

      Happy new year, everybody 🥬
      I've been sitting on this Dashboard module I made for a client and finally came around to cleaning it up and releasing it to the wider public. This is how it looks.
      ProcessWire Dashboard

      If anyone is interested in trying this out, please go ahead! I'd love to get some feedback on it. If this proves useful and survives some real-world testing, I'll add this to the module directory.
      Download
      You can find the latest release on Github.
      Documentation
      Check out the documentation to get started. This is where you'll find information about included panel types and configuration options.
      Custom Panels
      My goal was to make it really simple to create custom panels. The easiest way to do that is to use the panel type template and have it render a file in your templates folder. This might be enough for 80% of all use cases. For anything more complex (FormBuilder submissions? Comments? Live chat?), you can add new panel types by creating modules that extend the DashboardPanel base class. Check out the documentation on custom panels or take a look at the HelloWorld panel to get started. I'm happy to merge any user-created modules into the main repo if they might be useful to more than a few people.
       Disclaimer
      This is a pre-release version. Please treat it as such — don't install it on production sites. Just making sure 🍇
      Roadmap
      These are the things I'm looking to implement myself at some point. The wishlist is a lot longer, but those are the 80/20 items that I probably won't regret spending time on.
      Improve documentation & add examples ⚙️ Panel types Google Analytics ⚙️ Add new page  🔥 Drafts 🔥 At a glance / Page counter 404s  Layout options Render multiple tabs per panel panel groups with heading and spacing between ✅ panel wrappers as grid item (e.g. stacked notices) ✅ Admin themes support AdminThemeReno and AdminThemeDefault ✅ Shortcuts panel add a table layout with icon, title & summary ✅ Chart panel add default styles for common chart types ✅ load chart data from JS file (currently passed as PHP array) Collection panel support image columns ✅ add buttons: view all & add new ✅

      This module is inspired by and similar to the Template Stubs module. The author of that module has not been active in the PW community for several years now and parts of the code for that module didn't make sense to me, so I decided to create my own module. Auto Template Stubs has only been tested with PhpStorm because that is the IDE that I use.
      Auto Template Stubs
      Automatically creates stub files for templates when fields or fieldgroups are saved.
      Stub files are useful if you are using an IDE (e.g. PhpStorm) that provides code assistance - the stub files let the IDE know what fields exist in each template and what data type each field returns. Depending on your IDE's features you get benefits such as code completion for field names as you type, type inference, inspection, documentation, etc.
      Installation
      Install the Auto Template Stubs module.
      Configuration
      You can change the class name prefix setting in the module config if you like. It's good to use a class name prefix because it reduces the chance that the class name will clash with an existing class name.
      The directory path used to store the stub files is configurable.
      There is a checkbox to manually trigger the regeneration of all stub files if needed.
      Usage
      Add a line near the top of each of your template files to tell your IDE what stub class name to associate with the $page variable within the template file. For example, with the default class name prefix you would add the following line at the top of the home.php template file:
      /** @var tpl_home $page */ Now enjoy code completion, etc, in your IDE.

      Adding data types for non-core Fieldtype modules
      The module includes the data types returned by all the core Fieldtype modules. If you want to add data types returned by one or more non-core Fieldtype modules then you can hook the AutoTemplateStubs::getReturnTypes() method. For example, in /site/ready.php:
      // Add data types for some non-core Fieldtype modules $wire->addHookAfter('AutoTemplateStubs::getReturnTypes', function(HookEvent $event) { $extra_types = [ 'FieldtypeDecimal' => 'string', 'FieldtypeLeafletMapMarker' => 'LeafletMapMarker', 'FieldtypeRepeaterMatrix' => 'RepeaterMatrixPageArray', 'FieldtypeTable' => 'TableRows', ]; $event->return = $event->return + $extra_types; }); Credits
      Inspired by and much credit to the Template Stubs module by mindplay.dk.

      Jumplinks for ProcessWire
      Release: 1.5.60
      Composer: rockett/jumplinks
      ⚠️ NOTICE: 1.5.60 is an important security patch-release for an XSS vulnerability discovered by @phlp. It's HIGHLY RECOMMENDED that all Jumplinks users update to the latest version as soon as possible.
      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! 🙂
