python3库用于生成各种标识
customidenticon的Python项目详细描述
客户识别图标
用于生成各种标识图标的Python库
功能
- 3种不同类型的标识
- 更改最终图像大小（元素大小、元素数量）
- 更改边框大小
- 更改背景色
- 更改元素的透明度
- 更改输出格式（PNG、JPEG等）
- 哈希算法的选择（包括您自己的）
安装
pip install customidenticon
用法
结束图像大小=大小*块大小+边框*2
importcustomidenticonidenticon=customidenticon.create("Test data",# Datatype="pixels",# Type of algorithm (pixels, blocks or layers)format="png",# Output formatsalt="",# salt for more variantsbackground="#f0f0f0",# background colorblock_visibility=140,# transparency of elements in the image (0-255)block_size=30,# size of elements (px)border=25,# border (px)size=5,# number of elementshash_func=None# hash function (auto))
保存
importcustomidenticonidenticon=customidenticon.create("Test data",size=5)# identicon = b"\x89PNG\r\n\x1a\n\x00\x00\x00..."# save to filewithopen("identicon.png","wb")asf:f.write(identicon)# to imageimportiofromPILimportImageimage=Image.open(io.BytesIO(identicon))
哈希算法
对更改算法使用hashlib
importhashlibimportcustomidenticonidenticon=customidenticon.create("Test data",hash_func=hashlib.sha3_256)
自定义哈希算法示例
importcustomidenticonclassMySuperHashAlgorithm:def__init__(self,*args):passdefhexdigest(self):return"0"*200identicon=customidenticon.create("Test data",hash_func=MySuperHashAlgorithm)
示例
importcustomidenticon# Create github-like (5x5)identicon1=customidenticon.create("Test")# 200x200px (default for all)# oridenticon1=customidenticon.create("Test",type="pixels")# Create "pixels" type (6x6)# End image size 200x200px (6 * 25 + 25 * 2)identicon2=customidenticon.create("Test",size=6,block_size=25)# Create "layers" type (3 layer)# End image size 200x200px (default size = 3 and block_size = 50)identicon4=customidenticon.create("Test",type="layers")# Create "layers" type (8 layer)# End image size 200x200px (8 * 20 + 20 * 2)identicon5=customidenticon.create("Test",type="layers",size=8,block_size=20,border=20)# Create "blocks" type (3x3) (200x200px)identicon6=customidenticon.create("Test",type="block",block_visibility=100)
