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。
