I defined a blank line in my XHTML file as 2 consecutive HTML BR tags. Now there is no native support for a blank line in the XSL-FO format. I want to work around this limitation by adding a height to the fo:block that the stylesheet inserts for a BR tag. However I'm new to the XSLT language and I'm having some problems doing this. I can figure out how to insert this height for every BR tag I encounter, but I only want the blank line to be inserted when there

For a specific call I need to send 2 images using an ajax call to the API, so that the API can save them as varbinary(max) in the database. How do you extract an Image or byte[] from a HttpContent object? How do I do this twice? Once for each image. - var authToken = $("#AuthToken").val(); var formData = new FormData($('form')[0]); debugger; $.ajax({ url: "/api/obj/Create/", headers: { "Authorization-Token": authToken }, type: 'POST', xhr: function () { var myXhr = $.ajaxSettings.xhr(); return myXhr; }

I would like to use the NodaTime library to convert this to my local timezone but I can't seem to figure it out. My local timezone target is to be New Zealand. Here's what I have tried: var pattern = LocalDateTimePattern.CreateWithInvariantCulture("ddMMyyHHmmss"); var parseResult = pattern.Parse(utcDateTime); if (!parseResult.Success) { throw new InvalidDataException("Invalid time specified " + date + time); } var timeZone = DateTimeZoneProviders.Bcl

If the value is 10 - 20 put it in Medium, etc . . . if there any elegant way of doing it besides having nested if statements all put together? 回答1: May be not quite what you were looking for but how about using conditional formatting functionality of Excel EDIT: As an alternate you could create a vba function that acts as a formula that will do the

The script takes in three arguments: the input log file, the start time, and the end time. The start and end time are used to parse out a certain value on each line that that falls between those two times. But to properly run this I am converting the start and end time to epoch time. The problem I am having is that to convert the loops 'i' value back to normal time to compare against the log file. After running localtime($i) I

Can I convert this to a sparse matrix? I am expecting to gain time and space efficiencies by utilizing a sparse matrix instead of a data frame. Any help would be appreciated Update #1: Here is some code to generate the data frame. Thanks Richard for providing this x <- structure(list(name = structure(1:3, .Label = c("ABC", "DEF", "GHI"),

Is it possible to do it in python or I have to switch to C++? 回答1: You can use numpy conversion methods as an OpenCV mat is a numpy array. This works: img8 = ( img16 / 256 ). astype ( 'uint8' ) 回答2: You can do this in Python using NumPy by mapping the image trough a lookup table. import numpy as np def map_uint16_to_uint8 ( img , lower_bound = None , upper_bound = None ):
