python通过pil模块将raw图片转换成png图片的方法


            本文实例讲述了python通过pil模块将raw图片转换成png图片的方法。分享给大家供大家参考。具体分析如下：

python通过pil模块将raw图片转换成png图片，pil中包含了fromstring函数可以按照指定模式读取图片信息然后进行保存。





rawData = open("foo.raw" 'rb').read()

imgSize = (x,y)

# Use the PIL raw decoder to read the data.

# the 'F;16' informs the raw decoder that we are reading 

# a little endian, unsigned integer 16 bit data.

img = Image.fromstring('L', imgSize, rawData, 'raw', 'F;16')

img.save("foo.png")



其中Image.fromstring函数的第一个参数具体含义如下

1 (1-bit pixels, black and white, stored with one pixel per byte)

L (8-bit pixels, black and white)

P (8-bit pixels, mapped to any other mode using a colour palette)

RGB (3x8-bit pixels, true colour)

RGBA (4x8-bit pixels, true colour with transparency mask)

CMYK (4x8-bit pixels, colour separation)

YCbCr (3x8-bit pixels, colour video format)

I (32-bit signed integer pixels)

F (32-bit floating point pixels)

希望本文所述对大家的Python程序设计有所帮助。
