Find the complete version: public void line(int x,int y,int x2, int y2, int color) { int w = x2 – x ; int h = y2 – y ; int dx1 = 0, dy1 = 0, dx2 = 0, dy2 = 0 ; if (w<0) dx1 = -1 ; else if (w>0) dx1 = 1 … Read more
plt.plot returns a list of the Line2D objects plotted, even if you plot only one line. That comma is unpacking the single value into line. ex a, b = [1, 2] a, = [1, ]
In the simplest form, just plug the coordinates into the line equation and check for equality. Given: Point p (X=4, Y=5) Line l (Slope=1, YIntersect=1) Plug in X and Y: Y = Slope * X + YIntersect => 5 = 1 * 4 + 1 => 5 = 5 So yes, the point is on … Read more

Sorry, it hasn’t been replaced with anything. The first idea coming to my mind for emulating it would be the geometry shader. You feed the geometry shader with a line, compute its screen space length and based on that you generate a variable number of sub lines between its start and end vertex. EDIT: Perhaps … Read more
Here is a PictureBox subclass that supports the ability to apply zooming not only to the Image but also to graphics you draw onto its surface. It includes a SetZoom function to zoom in by scaling both itself and a Matrix. It also has a ScalePoint function you can use to calculate the unscaled coordinates … Read more
Use String.trim() method to get rid of whitespaces (spaces, new lines etc.) from the beginning and end of the string. String trimmedString = myString.trim();
Try SplFileObject echo memory_get_usage(), PHP_EOL; // 333200 $file = new SplFileObject(‘bible.txt’); // 996kb $file->seek(5000); // jump to line 5000 (zero-based) echo $file->current(), PHP_EOL; // output current line echo memory_get_usage(), PHP_EOL; // 342984 vs 3319864 when using file() For outputting the current line, you can either use current() or just echo $file. I find it clearer … Read more
Embrace the future! Just to be complete, you can also do this the Python 3k way by using the print function: from __future__ import print_function # Py 2.6+; In Py 3k not needed mylist = [’10’, 12, ’14’] # Note that 12 is an int print(*mylist,sep=’\n’) Prints: 10 12 14 Eventually, print as Python statement … Read more
You can make your code simpler and more readable like this bad_words = [‘bad’, ‘naughty’] with open(‘oldfile.txt’) as oldfile, open(‘newfile.txt’, ‘w’) as newfile: for line in oldfile: if not any(bad_word in line for bad_word in bad_words): newfile.write(line) using a Context Manager and any.
