Ruby Image Resize
How it works
- The image gets uploaded to your server.
- When the image is stored to the disk on server side, it is also resized.
Image Upload
In the Server Upload article we explain the steps to upload image on your server. After you insert an image in the rich text editor, you can resize it, but this only changes the width and height displayed in the browser, and not the physical size of the image. That should be done on server side.
Resize Image
The WYSIWYG editor's Ruby SDK comes with the possibility to resize the image when it is being stored on the disk. It is using the Ruby MiniMagick::Image method, therefore all the options available for it can be used.
class UploadController < ActionController::Base
...
def upload_image
options: {
resize: {
height: 200,
width: 600
}
}
FroalaEditorSDK::Image.upload(params, "public/uploads/images/", options)
end
...
end
Complete Example
<script>
new FroalaEditor('.selector', {
// Set the image upload URL.
imageUploadURL: '/image_upload',
imageUploadParams: {
id: 'my_editor'
}
})
</script>
class UploadController < ActionController::Base
...
def image_upload
options: {
resize: {
height: 200,
width: 600
}
}
render :json => FroalaEditorSDK::Image.upload(params, "public/uploads/images/", options)
end
...
end
