How to map a point onto a warped grid

问题 Say you have a collection of points with coordinates on a Cartesian coordinate system. You want to plot another point, and you know its coordinates in the same Cartesian coordinate system. However, the plot you're drawing on is distorted from the original. Imagine taking the original plane, printing it on a rubber sheet, and stretching it in some places and pinching it in others, in an asymmetrical way (no overlapping or anything complex).

I had recently participated in coding competion sponsored by an company and there was this one question which I did not understood, as to what was it asking. Here is the question: The string "paypal is the faster, safer way to send money" is written in a clockwise spiral pattern inside a square starting from the upper left corner: (you may want to display this pattern in a fixed font for better legibility).

The HTML scheme is following: <div class="items"> <div class="item">...</div> <div class="item">...</div> <div class="item">...</div> ... </div> .item CSS style: float: left; And the result: But the white boxes are not aligned right one after another one -- where could be the issue? I;ve tried also using display: inline-block; instead of float: left; , but the result was basically the same. Thank you You can use CSS 3 column-width and column-gap like this.. http://www.bootply.com/118335 I run into the exact same problem and I found this one that worked for me. https://github.com/kudago

Create an optimal grid based on n-items, total area, and H:W ratio

不羁的心 提交于 2019-11-30 06:58:40
I'm creating an application that takes a number of equally sized rectangles and positions them in a grid on the screen. I have most of the logic complete for resizing and centering a rectangle within a cell but I'm having trouble with the actual portion that defines the grid the rectangles must conform to. Ideally, in the end I'd have a function like this (pseudo-code): function getGridDimensions (rect surface, int numItems, float hwRatio) { // do something to determine grid-height and grid-width return gridDimensions; } My original stab at this involved something like this: gridHeight =

Grid drawn using a <canvas> element looking stretched

I'm trying to draw a grid on a <canvas> element with the ultimate goal of making a Go board . For some reason the grid is looking stretched, with the lines being thicker than 1 pixel and the spacing being completely wrong. It doesn't even start in the (10,10) position.. It would be great if someone could take a look at tell me what I'm doing wrong. http://jsfiddle.net/h2yJn/ I've found the problem. I was setting the dimensions of the <canvas> using CSS, when you actually have to set the width and height attributes. This was causing it to be stretched/skewed. var canvas = $('<canvas/>').attr(

How to set row border and background color in WPF Grid

我只是一个虾纸丫 提交于 2019-11-30 06:37:17
How can we set border and background color in the WPF grid control , i am creating rows and column dynamically and adding then to grid, can we set color and border from the code behind? Rachel The Background color can just be set for the entire Grid by using the Background property: <Grid Background="Red" /> Or if you want it set for individual cells, you need to add an element to the cell that has its Background property set. As for Borders, a Grid only contains the ShowGridLines property, which can be used to show thin dotted lines that cannot be styled. Per MSDN: Only dotted lines are

In C#, how do you send a refresh/repaint message to a WPF grid or canvas?

问题 How do you send a refresh message to a WPF grid or canvas? In other words, I have noticed while in debug mode, I can write code that sends a line to the display and then, if that line is not right, I can adjust it -- but the previous line is still there. Now, the code I am writing sends information to the display based on what the user clicks. So this must mean that the display is not refreshed each time a new set of lines and boxes and text goes to the grid or canvas in WPF. Using C# code,

Submit form with Kendo MVC Grid and other elements

安稳与你 提交于 2019-11-30 05:01:45
I am trying to get a form containing a Kendo MVC grid and other elements to submit. The View model contains contains three string fields and an IEnumerable collection. The grid is server bound. I am not adding any elements or deleting any elements from the list using the grid but the grid contains a check box mapped to a boolean column in the list items. Whenever I submit this form the three string elements return in the post method but the list is always null. Here is the data model: public class Parent { public string Field1 { get; set; } public string Field2 { get; set; } public string

RecyclerView layoutmanager for changing row and column span

安稳与你 提交于 2019-11-30 04:00:12
I am looking to create the following layout (red sqaures does not really have to be squares, a custom fixed height is also fine). The layout seems very simple yet I did not find a layout manager which suits my needs. I tried the StaggeredGridLayoutManager but this only allows to set the span of either the column or the row, not both. Is there floating around a custom layout manager which is able to do this? I have looked at TwoWayView but changing height seems to be problematic and the library is not being maintained. Anyone having this problem and solved it? A little bit late, but it might
