Object Storage Service:Persegi panjang dengan sudut membulat

Membulatkan sudut gambar dengan izin public-read atau public-read-write

Tambahkan parameter kueri x-oss-process ke URL gambar.

Contoh berikut menggunakan gambar sumber:

https://oss-console-img-demo-cn-hangzhou.oss-cn-hangzhou.aliyuncs.com/example.jpg

Contoh 1: Membulatkan sudut dengan radius 30 piksel

Parameter:

• Radius sudut: rounded-corners,r_30

• Format output: format,jpg (abaikan jika gambar sumber sudah berformat JPG)

https://oss-console-img-demo-cn-hangzhou.oss-cn-hangzhou.aliyuncs.com/example.jpg?x-oss-process=image/rounded-corners,r_30

Contoh 2: Memotong, membulatkan sudut, dan menyimpan sebagai PNG

Parameter:

• Potong menjadi 100×100 piksel dari posisi awal default: crop,w_100,h_100

• Radius sudut: rounded-corners,r_10

• Format output: format,png

https://oss-console-img-demo-cn-hangzhou.oss-cn-hangzhou.aliyuncs.com/example.jpg?x-oss-process=image/crop,w_100,h_100/rounded-corners,r_10/format,png

Membulatkan sudut gambar privat
