本文实例讲述了python处理图片之PIL模块简单使用方法。分享给大家供大家参考。具体实现方法如下:
#!/usr/bin/env python #encoding: utf-8 import Image class myimg: def __init__(self, open_file, save_file): self.img = Image.open(open_file) self.save_file = save_file def Change_Size(self, percent=100, height=None, width=None): ''''' percent:以百分比来决定大小 height, width:以指定的高、宽来决定大小 ''' if not (height and width): width,height = self.img.size new_img = self.img.resize((width*percent/100,height*percent/100),Image.BILINEAR) new_img.save(self.save_file) def Rotation(self, angle): ''''' angle: 旋转的度数 ''' rot_img = self.img.rotate(angle) #旋转 rot_img.save(self.save_file) def Save_as(self, filename): ''''' filename: 另存为图片格式,直接根据后缀名来 ''' self.img.save(filename) def Draw_Something(self): ''''' 利用ImageDraw来画图形 ''' import ImageDraw draw = ImageDraw.Draw(self.img) width,height = self.img.size draw.line(((0,0),(width-1,height-1)),fill=255) #画直线 draw.line(((0,height-1),(width-1,0)),fill=255) draw.arc((0,0,width-1,height-1),0,360,fill=255) #画椭圆 self.img.save(self.save_file) def Enhance_Something(self): ''''' 利用 ImageEnhance来增强图片效果 ''' import ImageEnhance brightness = ImageEnhance.Brightness(self.img) bright_img = brightness.enhance(2.0) ##亮度增强 bright_img.save(self.save_file) sharpness = ImageEnhance.Sharpness(self.img) sharp_img = sharpness.enhance(7.0) #锐度增强 sharp_img.save(self.save_file) contrast = ImageEnhance.Contrast(self.img) #对比度增强 contrast_img = contrast.enhance(2.0) contrast_img.save(self.save_file) if __name__ == "__main__": file_name = r"D:\test.png" save_file = r"D:\save.png" saveas_file = r"D:\save_as.bmp" oimg = myimg(file_name, save_file) oimg.Change_Size(30) oimg.Rotation(45) oimg.Save_as(saveas_file) oimg.Draw_Something() oimg.Enhance_Something()

PS:此外还有另一个比较常用的模块,image模块。
希望本文所述对大家的Python程序设计有所帮助。
