tiler--python实现的有趣的自定义马赛克图像拼接工具

最近在github中发现了一个有趣的小工具，tiler

github链接https://github.com/nuno-faria/tiler

具体介绍请直接去github，这里只分享一下它的使用方法。

需要安装的库在requirements.txt中

可以在cmd中定位到此文下直接使用命令

pip3 install -r requirement.txt安装所需要的库.

如果安装报timeout错误的话可以使用命令此（设置超时为30s）

pip3 install --timeout 30 -r requirements.txt

使用方法非常简单

打开文件夹下的conf.py文件

修改主要的三个参数

# out file name
OUT = 'out.png'
# image to tile (ignored if passed as the 1st arg)
IMAGE_TO_TILE = None
# folder with tiles (ignored if passed as the 2nd arg)
TILES_FOLDER = None

OUT是输出图片的文件名，可以为默认。

IMAGE_TO_TILE是需要自己修改的，输入图片路径不可以有中文字符，cv2无法打开此图片文件导致之后加载图片报错

TILES_FOLDER参数，是tiles文件夹下文件夹路径

TILES_FOLDER参数可以是此文件夹下的这些，当然你也可以自己添加一些。

不过要注意的是conf.py是py文件注意字符串要加' '或“ ”

例如：

TILES_FOLDER = "E:/workSpace/python_bug/tiler-master/tiles/times/gen_times"

测试了一下，我的电脑CPU 酷睿i5 7300U 8GB内存，输入命令运行程序

>python tiler.py

运行中内存占用比较高，原始图片1319x742像素

总共跑了大约1分钟。最终效果:

最终成品还是比较不错的。

参数设置：

DEPTH = 4
# list of rotations, in degrees, to apply over the original image
ROTATIONS = [0]

#############################

# TILER CONFS

# number of colors per image
COLOR_DEPTH = 32
# tiles scales (1 = default resolution)
RESIZING_SCALES = [0.5,0.4.0.3,0.2,0.1]
# number of pixels shifted to create each box (tuple with (x,y))
# if value is None, shift will be done accordingly to tiles dimensions
PIXEL_SHIFT = (5,5)
# if tiles can overlap
OVERLAP_TILES = False
# render image as its being built
RENDER = False
# multiprocessing pool size
POOL_SIZE = 4

# out file name
OUT = 'min.png'
# image to tile (ignored if passed as the 1st arg)
IMAGE_TO_TILE = 'E:/workSpace/python_bug/tiler-master/in1.jpg'
# folder with tiles (ignored if passed as the 2nd arg)
TILES_FOLDER = "E:/workSpace/python_bug/tiler-master/tiles/minecraft"

　　生成效果

参数设置

# number of divisions per color (R, G and B)
# DEPTH = 4 -> 4 * 4 * 4 = 64 colors
DEPTH = 128
# list of rotations, in degrees, to apply over the original image
ROTATIONS = [0]

#############################

　生成效果

可以看出DEPTH，COLOR_DEPTH 是控制图片颜色主要参数。
