前言
看电影的时候发现一个照片墙的功能,觉得这样生成照片挺好玩的,于是就动手用Python做了一下,觉得用来作照片纪念的效果可能会不错。
P:后面了解到我想做的功能叫蒙太奇拼图,所以这篇博客记录先留着,闲下来会去看一下蒙太奇拼图的算法

效果
实现过程
1.获取图片文件夹的图片个数N,将底图拆分成XY块区域,且使X * Y
(为了保证整体的协调,会舍弃几张图片,比如5张时可能只取22的4张图片)# 打开图片
base = Image.open(baseImgPath)
base = base.convert('RGBA')
# 获取图片文件夹图片并打乱顺序
files = glob.glob(imagesPath + '/*.*')
random.shuffle(files)
# 图片数量
num = len(files)
# 底图大小
x = base.size[0]
y = base.size[1]
# 每张图片数量 这个公式是为了xNum * yNum 的总图片数量
yNum = int((num / (y / x)) ** 0.5)
if yNum == 0:
yNum = 1
xNum = int(num / yNum)
# 图片大小 因为像素没有小数点 为防止黑边所以+1
xSize = int(x / xNum) + 1
ySize = int(y / yNum) + 1
2.遍历文件夹的图片,依次填充生成最终合成图for file in files:
fromImage = Image.open(file)
i = int(num % xNum)
j = int(num / xNum)
out = fromImage.resize((xSize, ySize), Image.ANTIALIAS).convert('RGBA')
toImage.paste(out, (i * xSize, j * ySize))
toImage = toImage.convert('RGBA')
img = Image.blend(base, toImage, 0.3)
# 显示图片
photo = ImageTk.PhotoImage(img)
showLabel.config(image=photo)
showLabel.image = photo
if num < xNum * yNum:
num = num + 1
3.生成结束后保存图片
toImage.save(‘generator.png’)
img.save(“final.png”)
4.建立可视化界面
5.Pyinstaller生成exe可执行文件
安装pyinstaller模块,执行命令生成exe文件pyinstaller -F -w test.py (-w就是取消窗口)
整体代码
Python的语法和设计规范还没学过,所以代码规范代码复用之类的可能会有点不到位,本博文主要是一个思路与整体流程的记录。
后续又优化了一下一些特效,比如合成图片采用随机位置,增加黑白,流年等显示特效,透明度自选等。import PIL.Image as Image
