TRICK - Crop images inside preserve ratio (no white spaces arround image)

[antuan]

Hello and sorry form my english.

Searching a metod for clean the white spaces for the images i probe this and run ok.
In admin/functions.php change arround the line 197 change the simbol > for <.
The crop images dont show withe spaces (crop outside) and generate a proportional images fill all the type images (small, large, etc...) (crop inside)

I probe in V1.0.


Original:

if (intval(Configuration::get('PS_IMAGE_GENERATION_METHOD')) == 2 OR (intval(Configuration::get('PS_IMAGE_GENERATION_METHOD')) == 0 AND $widthDiff > $heightDiff))

Modified:

if (intval(Configuration::get('PS_IMAGE_GENERATION_METHOD')) == 2 OR (intval(Configuration::get('PS_IMAGE_GENERATION_METHOD')) == 0 AND $widthDiff < $heightDiff))

Sorry sorry for my english. (im spanish)

Please note I found this code in the images.inc.php file. Thanks for the fix! I did a small test and it looks like it worked!

[coalesce]

Wanted to follow up. I'm using Prestashop 1.2.5.0, while the fix worked for the image resizing, when I went back and clicked on "catalog" in the admin area it failed to list products. This hack will break product management functionality in the backend this way... Will see if I can figure out a way around it as it was resizing images properly... Antuan any ideas?

Very strange, changed:

    if (intval(Configuration::get('PS_IMAGE_GENERATION_METHOD')) == 2 OR (intval(Configuration::get('PS_IMAGE_GENERATION_METHOD')) == 0 AND $widthDiff > $heightDiff))

to:

       if (intval(Configuration::get('PS_IMAGE_GENERATION_METHOD')) == 2 OR (intval(Configuration::get('PS_IMAGE_GENERATION_METHOD')) == 0 AND $heightDiff > $widthDiff))

and it now seems to be working... Hope this helps anyone having similar issues

i have V1.1 and dont have line 129 in admin/function.php

where i find it?

[RooTX]

The trick is working with 1.3 RC4 too.
As of 1.3, the line You are looking for is around 136 in /images.inc.php;

[Liberalis]

Hello, could anyone give me a hint on how exactly this works ?

I'm under v1.2.5 and changed the line in images.inc.php file.

When I regenerate the pictures, the white space is still there as if it had no impact.

Any help would be much appreciated.

I'm desperately trying to find a solution for the product image background to not have white stripes around the cropped image.

[sm3004]

Great trick for image cropping, no more whitespaces with Presta 1.3.1.1.

[airelibre]

Thanks, it works in Prestashop 1.3.2.3 too

[Roues]

Great, thanks!

[Edowardo]

Thank you, Its work.

And for the resizing of image as is what we want, you can combine or trying switch the ">" into "<"

because, i'll try the first option, but the image not cropping following the image frame, and then i try to switch the mark above vise verse and success the image fit on the frame and the background not white.

its cool, thank you

Hello.

I'm from Russia sorry for my bad English. The method works for prestashop version 1.4.6.2. Only have to change another Fail - images.inc.php

 

Change the sign of

 

if (Configuration:: get ('PS_IMAGE_GENERATION_METHOD') == 2 OR (! Configuration:: get ('PS_IMAGE_GENERATION_METHOD') AND $ widthDiff <$ heightDiff))

 

on

 

if (Configuration:: get ('PS_IMAGE_GENERATION_METHOD') == 2 OR (! Configuration:: get ('PS_IMAGE_GENERATION_METHOD') AND $ widthDiff > $ heightDiff))

 

If there are programmers or administrators interested I would like to add the ability to select a panel or module.

 

On

 

 

if (Configuration::get('PS_IMAGE_GENERATION_METHOD') == 2 OR (!Configuration::get('PS_IMAGE_GENERATION_METHOD') AND $widthDiff < $heightDiff))

 

If there are programmers or administrators interested I would like to add the ability to select a panel or module.

 

Sincerely Demos

[cankart]

Hi Demos, can you show me one example please ?

 

Thanks

[Amazzing]

Thank you for sharing!

 

Simply changing ">" to "<" in "images.inc.php" worked for me.

[KambinatoR]

Also worked on 1.4.5.1

 

PS: the file images.inc.php is in the root folder

[TiagoVieira]

worked in 1.4.7.3

 

after changing ">" to "<" just have to regenerate all thumbnails amd reload the protuct page.

 

thank you a lot

Can't prestashop provide some features like:

 

Background-Color: #xxxx

Rectangle-crop: yes/no

crop-position: top/left/...

 

This is all hardcoded :-(

 

This is a feature-wish, don't know where to post elsewhere

Hi just coming back to this thread.

 

I have tried the above but it simply crops out the left and right sections of my landscape images so that they are square. I simply want landscape images with *no* white border at the top and the bottom. Surely this is possible somehow?

[mactsolutions]

is there a way to just crop the thumbnails or a specific image size and not the large photos?

[Publisher]

Very strange, changed:

 if (intval(Configuration::get('PS_IMAGE_GENERATION_METHOD')) == 2 OR (intval(Configuration::get('PS_IMAGE_GENERATION_METHOD')) == 0 AND $widthDiff > $heightDiff))

 

to:

if (intval(Configuration::get('PS_IMAGE_GENERATION_METHOD')) == 2 OR (intval(Configuration::get('PS_IMAGE_GENERATION_METHOD')) == 0 AND $heightDiff > $widthDiff))

 

and it now seems to be working... Hope this helps anyone having similar issues

 

Thanks a lot, works fine with PS 1.4.2.5

[boogs]

Hi there,

 

Does anybody get the trick for PS 1.5.6 cause there isn't any such line in my images.inc.php file ?

 

Thanx

[sg1_anhell]

This works for Prestashop 1.6.0.9 BUT

 

only for new uploads, If then I regenerate images on back office doesn't work, back to fill with white...

 

In Prestashop 1.6 you will found the code lines in /classes/ImageManager.php

for me was the line 166

 

Only I changed

 

$width_diff > $height_diff

 

for

 

$width_diff < $height_diff

There is anyway we have cropping for just specific image type?

for example i want just product images cropped not the manufacturers!

[moy2010]

I just found these PHP functions for auto-cropping images' background:

 

http://php.net/manual/en/function.imagecropauto.php

 

These could help us save some KB in total pageload size and improve our prestashop stores.

Since this topic pops up if you google on how to remove the white bars; I'd thought I'd write my solution for PrestaShop 1.7 here.
Works for both formats, so portrait and landscape.
 

Step 1:

Open the following file:

/classes/ImageManager.php

Go to the line

if ($fileType == 'png' && $type == IMAGETYPE_PNG) {

and remove the last bit, so that it looks like:

if ($fileType == 'png') {

 

Step 2:

In your Backoffice, go to

Design > Image Settings

and set Image Format to Use PNG for all images
