I ONLY see the above value via inspect element, when I actually use `.get_attribute('src')` on the element, and print, it outputs this:
blob:https://express.adobe.com/31150ca9-e670-4165-a619-8cd95f2a5a6d
I am using Python Selenium to automate background removal via an online Adobe tool. I got all the way to downloading the image after the background is removed, but the img src is very strange and I am not sure how to download it.
This is the page: <https://express.adobe.com/tools/remove-background>
After uploading an image, the page removes the bg and shows a preview (on the same page). This is the image I am trying to download.
I tried using urllib requests to download it, but I get the error:
urllib.error.URLError: <urlopen error unknown url type: blob>

要下载图像，您可以将base64数据转换回二进制并将其保存为文件，例如：
```python
import base64
import io
from PIL import Image
data = "iVBORw0KGgoAAAANSUhEUgAAAyAAAAMgCAYAAADbcAZoAAAAAXNSR..." # 在这里使用您的base64字符串
if "data:image/png;base64," in data:
data = data.replace("data:image/png;base64,", "")
data_bytes = base64.b64decode(data)
image = Image.open(io.BytesIO(data_bytes))
image.save("output.png")
英文:
To download the image you can convert the base64 data back into binary and save it as a file, like for example:
import base64
import io
from PIL import Image
data = "iVBORw0KGgoAAAANSUhEUgAAAyAAAAMgCAYAAADbcAZoAAAAAXNSR..." # use your base64 string here
if "data:image/png;base64," in data:
data = data.replace("data:image/png;base64,", "")
data_bytes = base64.b64decode(data)
image = Image.open(io.BytesIO(data_bytes))
image.save("output.png")
