Triggering the Function

After the image is uploaded to bucket bucket-input-fg, OBS generates an event to trigger the image watermarking function. The function watermarks the image and stores the watermarked one into bucket bucket-output-fg. You can view running logs of fss_examples_image_watermark on the Logs tab page.

The Objects page of the bucket bucket-output-fg displays the watermarked image image.jpg, as shown in Figure 2. In the Operation column, click Download to download the image and view the watermarking effect, as shown in Figure 3.
