rectangles

问题 I'm trying to write a program that decides whether a circle is inside/touching a rectangle. The user puts in the center point for the circle and the radius, and two diagonal points for the rectangle. I'm not sure how to include all points of the circumference of the circle, to tell that there is at least one point in/touching the rectangle. Anyone sure how to do this? When I run my current program, I'll purposely enter points of a circle being inside of a rectangle, and should work with the

问题 Suppose I have a set of (X,Y) coordinates of 1000 boxes. ( x1, y1) ( x2, y2) Area (0.0000,0.0000) (0.3412,0.4175) 0.1424 (0.7445,0.0000) (1.0000,0.6553) 0.1674 (0.7445,0.6553) (1.0000,1.0000) 0.0881 (0.0000,0.6553) (0.7445,1.0000) 0.2566 (0.3412,0.0000) (0.7445,0.4175) 0.1684 (0.3412,0.4175) (0.7445,0.6553) 0.0959 (0.0000,0.4175) (0.3412,0.6553) 0.0812 ....etc I would like to calculate the number of adjacent boxes for each of them using c/c++ . How can I do it? Example In this picture, the

问题 I have hebrew text and when I am showing on UILabel it showing some rectangle. please help. Actual Text :- בָּרוּךְ אַתָּה יְיָ, אֱלֹהֵֽינוּ מֶֽלֶךְ הָעוֹלָם, בּוֹרֵא פְּרִי הָעֵץ out put :- UPDATE :- I have created the UILabel Manually using storyboard xib and set font name and rectangles gone but when i using on programatically created UILabel it is not working.I double checked Font Name is fine .Any idea?

问题 Let say that we have two rectangles, defined with their bottom-left and top-right corners. For example: rect1 (x1, y1)(x2, y2) and rect2 (x3, y3)(x4, y4) . I'm trying to find the coordinates(bottom-left and top-right) of the intersected rectangle. Any ideas, algorithm, pseudo code, would be greatly appreciated. p.s. I found similar questions but they check only if 2 rectangle intersect. 回答1: If the input rectangles are normalized, i.e. you already know that x1 < x2 , y1 < y2 (and the same for

问题 Sorry for the awful title. The purpose of the Java applet is as such: A ball is bouncing around the screen. The size and speed of this ball can be changed via scrollbars. The user can press and drag the mouse on the screen to draw rectangles. The ball will bounce off of these rectangles as well. The bounds of these rectangles are stored in a vector. When a rectangle is clicked, it (and all other rectangles at that point) are removed from the vector (and the screen). The problem I'm having is

问题 I have a rectangular chocolate bar that consists of squares either black, white or mixed. The bar being not bigger than 50x50 squares. I'm supposed to divide the bar between two people(one gets all the white squares and one the black ones, mixed ones don't matter), by cracking it either horizontally or vertically. I'm supposed to find a method with the least amount of such cracks. I'm given this input: M N (number of rows, number of columns) and then M rows that are N numbers long(0 means

问题 I am trying to write code for a rectangle class in BlueJ. When I compile my code I get the error "constructor Rectangle in class Rectangle cannot be applied to given types; required: no arguments; found: int, int, int, int; reason: actual and formal argument list differ in length". Also, I am confused on where to put the formula for a rectangle - width x height. I am trying to create class called rectangle that I could use in another class called picture. I am trying to use this class to make

I am comparing two images and find the difference using compare_ssim, in that case I got the contours of differences, which i need to highlight by drawing rectangle around it, but I am facing the issue that some of the rectangles overlapping each other I want to remove those overlapping. Given is

I mean all of the characteristic of the rectangles like borders , border-radius , triangulated quad on corners , etc. I don't like to use any other libraries except mine. I would like to create this one for the sake of learning and

问题 I need to evenly distribute a bunch of axis-aligned sliding rectangles constrained by a maximum width/height and by some horizontal/vertical coordinates depending from the position of the sliding shapes itself. Rectangles are constrained in one direction, can slide along the other axis, may not overlap and not step over as well. This question is based on: How to implement a constraint solver for 2-D geometry? and Spektre's well accepted proposal for a force-driven constraint solver. The whole
