Automatic images cropping for Prestashop 1.5.2 (free override)

[adhd_kid]

Hey guys, recently i've done 2 Prestashop templates that needed the zoom-crop functionality for certain image types ( see timthumb to know what i mean) . My first approach (it was Presta 1.4.x) was to override the The admin tabs and do lots of unneccessary stuff, then the other project came and when i was about to copy my old code i thought of a much better solution, so here it is :

 

0. Read our short introduction and copy code from here:

 

http://www.bazingade...restashop-1-5-2

 

or here (without introduction):

 

http://pastebin.com/eg2tLztL

 

1. Go to Preferences -> Images -> Add new and set the new image size that you want to be zoom-cropped (to fit the whole area)

 

2. Name the new image size adding the "_btt" suffix to it

 

3. regenerate your pictures, use the new picture name in your templates where neccessary and enjoy

 

*** In the attachment you will find an example of how should new image size with crop be named in the backoffice

 

**** Remember to actually use the new image size in your templates, like:

 

<img src="{$link->getImageLink($product.link_rewrite, $product.id_image, 'fbmag_btt')}" >

Ok Vinc3nzo, i updated the first post with an image example (ps have you used the new name of the file size in your template?)

[Vinc3nzo]

Hello,

 

I still do not understand how to use your wits. I change my files. TPL "home_default" and that's it foncitonne wrong, I do not understand the order of manipulations ... What exactly TPL file must be modified?

 

Can disable after "home_default"? or we are obliged to leave?

 

The pictures do not cut the product details on the "THUMBS" on mouseover ... :/

 

Thx you advance! good continuation!

 

 

PS: i have multiple image dimension...

Thanks for sharing

Hi Vincenzo, I just think that what you need to do is simple but you need a bit of further explanation. Tomorrow i should be having my day off from work so mail me: [email protected] and i'll see what your page outputs then will tell you what to do exactly so you can write this in your own words for others who might not understand what they need to do here, ok?

[nostradamus]

when i replace the file wiht the one u suggested i get a white page when i want to regenerate the images

[elvispl]

Or...

 

in ImageManager.php

 

repleace:

if (Configuration::get('PS_IMAGE_GENERATION_METHOD') == 2 || (!Configuration::get('PS_IMAGE_GENERATION_METHOD') && $width_diff > $height_diff))

 

to:

if (Configuration::get('PS_IMAGE_GENERATION_METHOD') == 2 || (!Configuration::get('PS_IMAGE_GENERATION_METHOD') && $width_diff < $height_diff))

 

works on 1.5.2

works on 1.5.2

Any update?

[adhd_kid]

Any update?

 

Mlis82 I've been using this piece of code throughout all the versions of Prestashop 1.5.x and it always works (either starting with a fresh installation or updating an existing one).

[mlis82]

I've just changed code like elvispl said and now it's work fine.

 

 

Best Regards

 

This pice of code is great:) Thank You a Lot

[jbenmouhar]

Hi,

 

must be put "ImageManager.php" file in "overrides/classes" or "override/classes /"?

I tested the two but nothing works

 

my file image name "test_btt"

 

prestashop 1.5.5.0

[tomasz_be]

Works great with 1.5.6. Thanks!

[nev]

This is awesome! It's such a great solution and really simple to do. Thanks adhd_kid!:)

For those people out there that were struggling like me, wondering why it didn't work at first, it's probably as simple as deleting the cashe/class_index.php file.

[Martin-F]

¡¡ Works perfectly with ps 1.5.4.1 !!

One question: Is it possible to modify the code in order to move a little bit (percent) the cropping to one side (left or right)???

Excellent contribution.

Thanks.

[adhd_kid]

@martinf you see this should not be a big task: the zoom-crop code is taken directly from Timthumb and all current versions of that script contain a number of ways you can crop the image (crop to left, right, bottom, top), so the only thing to do would be to paste the missing code and create additional conditions somewhere after the _btt suffix such as "_btt_l" (for zoop-crop left) or "_btt_r" for zoom-crop right :-)

Hi, 

 

I've replaced the code from classes/ImageManager.php and It doesn't work form me.. When I try to regenerate images, there is a fatal error 

 

Fatal error: Class 'ImageManagerCore' not found in /usr/home/../../classes/ImageManager.php on line 18

 

I'm using 1.5.6.2 version.

Could somebody help me?

 

Thanks!

[adhd_kid]

@dromansab are you sure you put the code into /overrides/classes/ImageManager.php ? If you replaced the /classes/ImageManager.php then you need to bring it back After you've done everything be sure to delete this file: /cache/class_index.php to make Prestashop aware of the changes.

[dromansab]

It works! I overwrote the original file..   Thanks!

[kamiliok]

 Saved my day!

 

Or...

in ImageManager.php

repleace:

if (Configuration::get('PS_IMAGE_GENERATION_METHOD') == 2 || (!Configuration::get('PS_IMAGE_GENERATION_METHOD') && $width_diff > $height_diff))

to:

if (Configuration::get('PS_IMAGE_GENERATION_METHOD') == 2 || (!Configuration::get('PS_IMAGE_GENERATION_METHOD') && $width_diff < $height_diff))

works on 1.5.2

 

 

Thanks! That works on 1.6 to.

Hello,

 

It works for Prestashop 1.6.0.9, But I've got an error when I go to the product list in the BO.

Unknow error à la ligne 152 du fichier /home/www/override/classes/ImageManager.php
[2048] Declaration of ImageManager::resize() should be compatible with ImageManagerCore::resize($src_file, $dst_file, $dst_width = NULL, $dst_height = NULL, $file_type = 'jpg', $force_type = false, &$error = 0)

Do you know what could be the issue ? Thanks

[Aminta]

Hi, here's the function adapted for PS 1.6, replace all the code in "classes/ImageManager.php" http://pastebin.com/3Hsk9s1e

[YanK]

My file ImageManager.php.zip : use "_crop"

With this file native class used for other images. Just used for image with "_crop" name.

[Gab]

Merci Yank, ca fonctionne à merveille

Dingue que ça ne soit toujours pas natif dans Prestashop...

[PrestaMathieu]

Hi,
It's really Great. It's work good with Presta 1.6.1.1

do you know if it's possible to crop with specific X et Y coordonate ?

[edit] it's in order to crop on the right of the picture and no in the center (default beahvior)

Thanks

[PrestaMathieu]

mini up... noboby have a solution for crop the right of the image and no the center ?

Edited October 12, 2015 by PrestaMathieu (see edit history)

[babyewok]

This all works great it 1.6.1.1

 

What I need now is an additional image resize method for thickbox images whereby prestashop does not resize images below the set image size. ie it doesn't add the white border if the image is smaller, it just leaves it, but does resize images that are larger. How can I do that?

[babyewok]

Hello,

 

It works for Prestashop 1.6.0.9, But I've got an error when I go to the product list in the BO.

Unknow error à la ligne 152 du fichier /home/www/override/classes/ImageManager.php

Do you know what could be the issue ? Thanks

 

Having the same issue - the error only shows though if I hhave developer mode set to true - any solutions??  The image resize all works fine, just get theis error in dev mode

 

EDIT:

 

Solved this issue (in 1.6.1.1) by changing the first line of the override to:

public static function resize($src_file, $dst_file, $dst_width = null, $dst_height = null, $file_type = 'jpg',
                              $force_type = false, &$error = 0, &$tgt_width = null, &$tgt_height = null, $quality = 5,
                              &$src_width = null, &$src_height = null)
