This widget allows you to select a rectangular area on the source image on the server, cache the new image and use it.
##Installation
The preferred way to install this extension is through composer.
Either run
php composer.phar require --prefer-dist evgkan/yii2-widget-crop-image "*"
or add
"evgkan/yii2-widget-crop-image": "*"
to the require section of your composer.json file.
##Use
###In admin(profile) view:
<?= $form->field($model, 'photo')->widget(CropImage::className()) ?>
After you submit the form the model attribute will contain an array with the data framing, like this:
[
'imgSrc' => <path>,
'x1' => <left 0..1>,
'y1' => <top 0..1>,
'x2' => <right 0..1>,
'y2' => <bottom 0..1>
]
###In model:
public function getCropPhoto(){
return CropImage::getCropImage($this->photo);
}
This method searches the cached image, using data framing. If cached image is absent, a new one is created. ###In common view:
<img src="<?= model->photo ?>"> <!-- original photo -->
<img src="<?= model->cropPhoto ?>"> <!-- croped and cached photo -->
##Warning! The widget uses a serverside file manager mihaildev/yii2-elfinder. It needs to be properly configured to access the server file system.
