At the risk of having this question voted as a duplicate, or even to have it closed, I had this question has come up. Background In "normal" data types such as int, long long, etc..., to convert from the binary numeric value to a decimal string, you would do the following (in pseudo code): Set length = 0 Set divisor to largest base10 value the data type will hold (Divisor). Loop Divide number in question by divisor. Place result in a string at position length. Increment the length by 1. Divide the divisor by 10. Reverse the string. Print the string. The actual implementation in (most) any

I have done some google-ing around and couldn't find enough information about this format. It is the default format for camera preview. Can anyone suggest good sources of information about it and how to extract data from a photo/preview image with that format? To be more specific, I need the black and white image extracted. EDIT: Seems like that format is also called YCbCr 420 Semi Planar I developed the following code to convert the NV21 to RGB, and it is working. /** * Converts YUV420 NV21 to RGB8888 * * @param data byte array on YUV420 NV21 format. * @param width pixels width * @param

问题 How do you convert Decimal Degrees to Degrees Minutes Seconds In Python? Is there a Formula already written? 回答1: This is exactly what divmod was invented for: >>> def decdeg2dms(dd): ... mnt,sec = divmod(dd*3600,60) ... deg,mnt = divmod(mnt,60) ... return deg,mnt,sec >>> dd = 45 + 30.0/60 + 1.0/3600 >>> print dd 45.5002777778 >>> decdeg2dms(dd) (45.0, 30.0, 1.0) 回答2: Here is my updated version based upon Paul McGuire's. This one should handle negatives correctly. def decdeg2dms(dd): is
