WPF -- Graphics draws a straight line and saves it as bitmap, wpfbitmap The solution is to draw a vertex set into a straight line and save it as a bitmap. First, determine the bitmap width and height based on the maximum value of the coordinate of the point set: Bitmap bmp = new Bitmap (width, height ); Create a Graphics-type object to create the image Graphics g = Graphics. FromImage (bmp ); Then draw a li

What? Simplest control flow: placing statements and statement blocks in sequenceWhy? Although organizing code with a straight line is a simple task, some of the nuances in the code structure still affect the code quality, correctness, readability, and maintainability.How? Must have statements in a clear order Make the dependency very obvious Enable subroutine names to highlight Dependencies Use subroutine parameters to indicate dependency Notes

Question: n lines are given to determine whether there is a straight line. All lines must have at least one public point after the projection of a straight line (intersection with all lines) I started to think wrong, because it is to determine whether a line exists in the given line segment to make it intersect with all line segments; This can also pass the sample input; I have been searching for it for a d

The basic principle of the straight line detection by using the Hough transform is for each point (x, y) in the X-Y coordinate system, corresponding to the polar coordinate is: ROV = x * Cos (theta) + y * sin (theta) (1) Therefore, for each point in the x-y plane, corresponding to the polar coordinate system is a straight line. If the points in the Cartesian coordinate system are collocated, the lines in th

/* Question: Ask some line segments if there is such a line: all these line segments have a common point projected on the line. If there is such a point, make the vertical line of this line, this vertical line is crossed by all line segments because the projection of all line segments covers this point, because their projection has this common point, it is to find a straight line that passes through all line segments. So, enumerate the
