First of all, thanks for sharing this amazing watermark tool!

The problem I came across is that, when I running the example code in the doc

# embed watermark into image:
blind_watermark --embed --pwd 1234 examples/pic/ori_img.jpeg "watermark text" examples/output/embedded.png

the output image (33.2 KB) is twice as large as the original image (17.7 KB), but the quality deteriorates

Is there a way to preserve the image quality?

Thanks!

Use wm.embed(..., compression_ratio=aFloat) to compression the output image.
