我有这个脚本,它成功地将水印应用于图像,调整水印大小并设置图像“质量”。 我发现它实际上降低了质量并将其调整为比我想要的小。
这是我正在使用的电报机器人,我将图像发送给机器人,机器人正在添加水印,然后调整大小。我根本不想要调整大小的部分。我要原尺寸+水印。
问题:如何更改此设置,使其不会调整添加水印的原始图像的大小?

这可能不是解决此问题的最佳方法,但它对我来说很有效,可以将其恢复到正常大小
double = 2.0
Image.composite(wm, img, wm).resize( [int(double * s) for s in img.size] ).save(out_path, 'JPEG', optimize=True, quality=config.QUALITY)
