Processing an Image
If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see the API Reference.
OBS can be used to process images in a stable, secure, efficient, easy to use, and cost-efficient manner. If the object to be downloaded is an image, you can pass the image processing parameters to process the image, including cutting and resizing it as well as putting a watermark and converting the format.
For more information, see the Image Processing Feature Guide.
Sample code:
// Create an instance of ObsClient.
var obsClient = new ObsClient({
access_key_id: '*** Provide your Access Key ***',
secret_access_key: '*** Provide your Secret Key ***',
server : 'https://your-endpoint'
});
obsClient.getObject({
Bucket : 'bucketname',
Key : 'objectname.jpg',
// Resize and then rotate the image.
ImageProcess : 'image/resize,m_fixed,w_100,h_100/rotate,90'
}, function (err, result) {
if(err){
console.error('Error-->' + err);
}else{
console.log('Status-->' + result.CommonMsg.Status);
}
});
- Use the ImageProcess parameter to specify the image processing parameters.
- Image processing parameters can be processed in cascading mode. This indicates that multiple commands can be performed on an image in sequence.
