问题 Given a starting point, a heading, a distance, and a line segment, find the first point along this heading that is the specified distance away from this line segment. I covered two cases, but I haven't been able to cover the last one. First case: heading away from the line. Ignore it even if the starting point is within the specified distance. Second case: It intersects the line. I solved it using trig and triangles. Initially didn't consider the next case. Third case: It is heading towards

问题 The bing map control for wp7 has two properties called Pitch and Heading, but setting those two properties does not seem to work. I expect them to rotate the map. Am I missing anything? Is there anything specific that needs to be done to make those two properties work? 回答1: That properties aren't avilable now on WP7. This is propertis for 3D Bing Map Control (rather desktop), not supported by WP7 yet. Better use transform on container with map (i.e. Canvas, but I can't check now...) 来源： https

Skipping heading levels in reStructuredText

问题 Is it possible in some way to skip heading levels in RestructuredText? For example, given #### PART #### ******* Chapter ******* Section ======= Subsection ---------- Subsubsection ^^^^^^^^^^^^ Paragraph """"""""" Another section =============== Another Paragraph """"""""""""""""" The above heading seems to be rendered as a subsection-level heading... The last paragraph gets rendered as a subsection instead of as a paragraph. (I am using Sphinx as a renderer.) So it seems section-level

How to underline section-headings in LaTeX?

问题 EDIT : As I see in the first answer, underline is the wrong word. I want a line under the section heading, separating the heading from the following text. I want to separate section headings from the following text with a horizontal line. At the moment I use the following: \newcommand{\tmpsection}[1]{} \let\tmpsection=\section \renewcommand{\section}[1]{\tmpsection{#1}\hrule\nobreak} But that produces a line, that is too far away from the section-heading and to near to the following text.

How to bind an action to the heading of a tkinter treeview in python?

由 丶灬走出姿态 提交于 2019-12-05 10:21:33
I am using the tkinter Treeview widget to show a database. The command when clicking on one of the headings is used for sorting the table based on the clicked column. Additionally I want a tooltip box show up as soon as I hover (or right click) over one of the headings. The tooltips aren't a problem for other widgets but the heading of a treeview isn't a full widget of course. How can I bind any action to the headings except for the usual command? You can bind the events to the treeview widget itself. The widget has a method named identify which can be used to determine which part of the

Using Compass to point to actual coordinate location instead of just North

由 泪湿孤枕 提交于 2019-12-04 16:53:02
I have seen a few examples of this but am not sure exactly how to implement it, (such as iPhone Compass GPS Direction ) in do I need to call calcBearingWithLatitude in (void)startup? All I am trying to do is have the compass pull a point from memory and use that point as its "north" so to speak and point to it, no need for distance or anything like that. My implementation file as of now looks like @implementation TrackerViewController @synthesize locationManager; @synthesize compass; @synthesize headingLabel; - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; if (

How to calculate Heading using Gyro and magnetometer

由 强颜欢笑 提交于 2019-12-03 16:14:58
I have raw data of Gyroscope and magnetometer. on basis of this data, i have to calculate Heading information with an accuracy of 1Deg. I would like to know, is there any algorithm which can help me to get heading info using available information with mentioned accuracy? Any article or any link also will be helpful. Thanks I am assuming you are using phone to collect gyroscope+magnetometer data. You cannot calculate Heading with Gyro+Magnetometer unless you know initial state of device. You have to try Accelerometer+Magnetometer . You can get heading values from rotation-matrix' or yaw`
