This article illustrates python's method of converting raw images to PNG images through the pil module. Share with you for your reference. Specific analysis is as follows:
Python converts raw images to PNG images through the pil module, which includes the fromstring function that reads the images in the specified mode and then saves them.
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")
The first argument to the image.fromstring function has the following meaning
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)
