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()

and what is the output from:

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

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.

      Hi! I've created a small Inputfield module called InputfieldFloatRange which allows you to use an HTML5 <input type="range" ../> slider as an InputField. I needed something like this for a project where the client needs to be able to tweak this value more based on 'a feeling' than just entering a boring old number. Maybe more people can use this so I'm hereby releasing it into the wild. 
      EDIT: You can now install it directly from the Modules directory: http://modules.processwire.com/modules/inputfield-float-range/
       
      What is it?
      The missing range slider Inputfield for Processwire. 
      What does it do?
      This module extends InputfieldFloat and allows you to use HTML5 range sliders for number fields in your templates.
      It includes a visible and editable value field, to override/tweak the value if required.  
      Features
      Min/max values Precision (number of decimals) Optional step value (Read more) Optional manual override of the selected value (will still adhere to the rules above) Configurable rounding of manually entered values (floor, round, ceil, disable) Usage
      Clone / zip repo Install FieldtypeFloatRange, this automatically installs the Inputfield Create new field of type `Float (range)` or convert an existing `Float`, `Integer` or `Text` field. To render the field's value simply echo `$page->field` Demo
      A field with Min=0, Max=1, Step=0.2, Precision=2

      Field with settings Min=0, Max=200, Step=0.25, Precision=2

       
      Todo
      Make the display-field's size configurable (will use the Input Size field setting)  Hopefully become redundant  
      Changelog
      004 (current version)
      - Make rounding of manually entered values configurable (floor, round, ceil or disable)
      - Fix small JS bug when the value-display field was not displayed
      - Update README
      003
      - Code cleanup, add some ModuleInfo data & LICENSE
      - Submit to PW Modules directory (http://modules.processwire.com/modules/inputfield-float-range/)
      002
      - Fix issue where setting the step value to an empty value created problem with validation
      - Make the display-field optional
      001
      - Initial release
       
      Thanks!

      Please note that the software is not yet intended for use in a production system (alpha version).
      If you like, you can also submit feature requests and suggestions for improvement. I also accept pull requests.
      ---- 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)

      Another little admin helper module...
      Template Field Widths
      Adds a "Field widths" field to Edit Template that allows you to quickly set the widths of inputfields in the template.

      Why?
      When setting up a new template or trying out different field layouts I find it a bit slow and tedious to have to open each field individually in a modal just to set the width. This module speeds up the process.
      Installation
      Install the Template Field Widths module.
      Config options
      You can set the default presentation of the "Field widths" field to collapsed or open. Field widths entered into the Template Field Widths inputfield are only applied if the Edit Template form is submitted with the Template Field Widths inputfield in an opened state. "Collapsed" is the recommended setting if you think you might also use core inputs for setting field widths in a template context. You can choose Name or Label as the primary identifier shown for the field. The unchosen alternative will become the title attribute shown on hover. You can choose to show the original field width next to the template context field width.
