本文實例講述了python通過pil模塊將raw圖片轉換成png圖片的方法。分享給大家供大家參考。具體分析如下：

python通過pil模塊將raw圖片轉換成png圖片，pil中包含了fromstring函數可以按照指定模式讀取圖片信息然后進行保存。

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函數的第一個參數具體含義如下

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)

希望本文所述對大家的Python程序設計有所幫助。
