使用python脚本为图片添加文字水印

marker.py

为图片添加文字水印 可设置文字大小、颜色、旋转、间隔、透明度

usage

需要 PIL 库 pip install Pillow

usage: marker.py [-h] [-f FILE] [-m MARK] [-o OUT] [-c COLOR] [-s SPACE] [-a ANGLE] [--font-family FONT_FAMILY] [--font-height-crop FONT_HEIGHT_CROP] [--size SIZE]
                 [--opacity OPACITY] [--quality QUALITY]

optional arguments:
  -h, --help            show this help message and exit
  -f FILE, --file FILE  image file path or directory
  -m MARK, --mark MARK  watermark content
  -o OUT, --out OUT     image output directory, default is ./output
  -c COLOR, --color COLOR
                        text color like '#000000', default is #8B8B1B
  -s SPACE, --space SPACE
                        space between watermarks, default is 75
  -a ANGLE, --angle ANGLE
                        rotate angle of watermarks, default is 30
  --font-family FONT_FAMILY
                        font family of text, default is './font/青鸟华光简琥珀.ttf'
                        using font in system just by font file name
                        for example 'PingFang.ttc', which is default installed on macOS
  --font-height-crop FONT_HEIGHT_CROP
                        change watermark font height crop
                        float will be parsed to factor; int will be parsed to value
                        default is '1.2', meaning 1.2 times font size
                        this useful with CJK font, because line height may be higher than size
  --size SIZE           font size of text, default is 50
  --opacity OPACITY     opacity of watermarks, default is 0.15
  --quality QUALITY     quality of output images, default is 90

效果

python marker.py -f ./input/test.png -m 添加水印

watermarker's Issues

加完水印后的图片质量被压缩了

你好，加完水印后的图片质量被压缩了，能否保留原图的质量？

Error： AttributeError: 'str' object has no attribute 'decode'

Traceback (most recent call last):
File "marker.py", line 142, in
main()
File "marker.py", line 129, in main
args.mark = args.mark.decode("utf-8")
AttributeError: 'str' object has no attribute 'decode'

当给超清图片进行加水印的时候, 处理后的图片会旋转90度 (我测试图片的体积是 26 MB)

如题: 加水印后的图片会旋转90度数, 加上 --quality=100 还是无济于事, 我测试图片的体积是 26 MB, 当时用单反拍出来的

test.png Success之后打开图片还是原图片并无新增水印

本来是python执行的，但是会报错，后面自己尝试python3虽然能成功，但是查看图片的时候图片完全没有变化，仍旧是原本的图片

UnicodeDecodeError: 'utf8' codec can't decode byte

λ python marker.py -f a.jpg -m "中aaa"
Traceback (most recent call last):
  File "marker.py", line 160, in <module>
    main()
  File "marker.py", line 146, in main
    args.mark = args.mark.decode("utf-8")
  File "C:\Python27\lib\encodings\utf_8.py", line 16, in decode
    return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf8' codec can't decode byte 0xa4 in position 1: invalid start byte

作者你真好

爱作者 这工具太棒啦 可以贴个收款码

solve:
change this:

TTF_FONT = os.path.join("font", "青鸟华光简琥珀.ttf")

to

TTF_FONT = os.path.join("font", "cn.ttf")

指定字体为Windows默认fonts路径下的黑体，无法加水印

无法直接引用windows自带的字体，带空格名称的字体都不好使，不带空格的字体能使用，尝试过用“”，但是也不行

颜色参数无法设置

-c 参数是无效的

一个特别小的问题，图片质量在说明里说默认是90，其实默认设的是80

 parse.add_argument("--quality", default=80, type=int,
                       help="quality of output images, default is 90")

应为：

 parse.add_argument("--quality", default=90, type=int,
                       help="quality of output images, default is 90")
