System library image php

OpenCart — изображения одинакового размера

Однажды я столкнулся с вопросом вывода изображений одинакового размера, но т.к. фотографии оказались то горизонтальными, то вертикальными — это немного осложнило задачу. Впрочем, не на много (:

И чтобы не изобретать велосипед, я полез на просторы интернета и нашел решение (Автор: shishifr1 с opencartforum.ru, по-крайней мере, это был его пост).

1) идем в /catalog/models/tool/image.php и вставляем функцию:

public function myresize($filename, $width, $height) < if (!file_exists(DIR_IMAGE . $filename) || !is_file(DIR_IMAGE . $filename)) < return; >$info = pathinfo($filename); $extension = $info['extension']; $old_image = $filename; $new_image = 'cache/' . substr($filename, 0, strrpos($filename, '.')) . '-' . $width . 'x' . $height . '.' . $extension; if (!file_exists(DIR_IMAGE . $new_image) || (filemtime(DIR_IMAGE . $old_image) > filemtime(DIR_IMAGE . $new_image))) < $path = ''; $directories = explode('/', dirname(str_replace('../', '', $new_image))); foreach ($directories as $directory) < $path = $path . '/' . $directory; if (!file_exists(DIR_IMAGE . $path)) < @mkdir(DIR_IMAGE . $path, 0777); >> $image = new Image(DIR_IMAGE . $old_image); $image->myresize($width, $height); $image->save(DIR_IMAGE . $new_image); > if (isset($this->request->server['HTTPS']) && (($this->request->server['HTTPS'] == 'on') || ($this->request->server['HTTPS'] == '1'))) < return HTTPS_IMAGE . $new_image; >else < return HTTP_IMAGE . $new_image; >>

2) Далее открываем файл /system/library/image.php и добавляем:

public function myresize($width = 0, $height = 0) < if (!$this->info['width'] || !$this->info['height']) < return; >$x = $this->info['width']; $y = $this->info['height']; // old images width will fit if(($x / $y) < ($width/$height))< $scale = $width/$x; $newX = 0; $newY = - ($scale * $y - $height) / 2; // else old image's height will fit >else < $scale = $height/$y; $newX = - ($scale * $x - $width) / 2; $newY = 0; >$image_old = $this->image; $this->image = imagecreatetruecolor($width, $height); $new_width = $scale * $x; $new_height = $scale * $y; // now use imagecopyresampled imagecopyresampled($this->image, $image_old, $newX, $newY, 0, 0, $new_width, $new_height, $x, $y); if (isset($this->info['mime']) && $this->info['mime'] == 'image/png') < imagealphablending($this->image, false); imagesavealpha($this->image, true); $background = imagecolorallocatealpha($this->image, 255, 255, 255, 127); imagecolortransparent($this->image, $background); > else < $background = imagecolorallocate($this->image, 255, 255, 255); > imagedestroy($image_old); $this->info['width'] = $width; $this->info['height'] = $height; >

3) Теперь можем «ресайзить» изображения или стандартной функцией или приведенной выше. Для этого в контроллере (например, в категориях /catalog/controller/product/category.php) нужно найти

if ($result[‘image’]) < $image = $this->model_tool_image->resize($result[‘image’], $this->config->get(‘config_image_product_width’), $this->config->get(‘config_image_product_height’)); > else

и заменяем функцию с resize на myresize:

$image = $this->model_tool_image->myresize($result['image'], $this->config->get('config_image_product_width'), $this->config->get('config_image_product_height'));

PS: если у вас установлен FilterPro или что-то похожее, то нужно в контроллере фильтра в функции получения товара проделать пункт 3)

Вот и все! Теперь картинки будут обрезаться под один размер и заполнять все пространство!

Invalid image dimensions in image.php on line 105

Product images are not appearing in categories, and many PHP errors are appearing at the top of the page. Interesting to note, the product image URLs are broken in an unusual way. In the following HTML output (cut for size), the filename is missing the height portion of the file name (see correct file in bold).

Checking the filesystem, the correct image file is filename-228×228.png.

On the top of the page output:

Warning: imagecreatetruecolor(): Invalid image dimensions in /html/store/system/library/image.php on line 105Warning: imagealphablending() expects parameter 1 to be resource, boolean given in /html/store/system/library/image.php on line 108Warning: imagesavealpha() expects parameter 1 to be resource, boolean given in /html/store/system/library/image.php on line 109 . plus many more

I can’t find the source of this bug. Is anyone else experiencing this issue? . does OpenCart require thumbnails to be resized before upload? . or maybe there is a required PHP library that is not installed, and not generating an error?

System, Users, User Groups, Administrator: grant permission to access and modify the theme

Extensions, Themes, click edit, then save.

No idea why this would come out of the box like this.

Can you show code for resize image at file controller?
Please note :
Opencart 2.2.0.0 have different code with older version for image resize, example
code for 2.2.0.0 like this :

$image = $this->model_tool_image->resize($result['image'], $this->config->get($this->config->get('config_theme') . '_image_product_width'), $this->config->get($this->config->get('config_theme') . '_image_product_height')); 

$image = $this->model_tool_image->resize($result['image'], $this->config->get('config_image_product_width'), $this->config->get('config_image_product_height'));

Are you install images width & height?

Ps. This it is theme autors new jobs. Theme authors need create theme setting files admin/controller/theme/theme_xxxx.php, admin/view/template/theme/theme_xxxx.tpl and admin/language/*/theme/theme_xxx.php

Ps 2: My test this is not can change theme. This line 60 in file loader.php add automaticilly prefix ‘default/template/’:

$result = $this->registry->get('event')->trigger('view/' . $route . '/before', array(&$route, &$data));

$template = str_replace('default','peku',$template); return $this->adaptor->render($template);

what about when you go to admin > extension > theme > Default Store Theme

then set the field Theme Directory to the name of the custom theme?

Thanks! This is work!
Here it is possible to add your own theme configuration files, but they are not yet able to use

As a note, this dimension image issue also happen when theme you choose at system > setting have status disabled on extensions > themes.

So make sure to never disabled your active theme.
