lines

Question, if I wanted to create gradient lines that fade out on the top and bottom, similar to the lines seen on AT&T's drop down menu that separate the menu items, how would I go about that? I want to create a similar effect on a menu that I am coding, and I would prefer not to use images. Is there a way to achieve this in CSS? Help much appreciated! Thanks. Microsoft CSS Gradient is a GUI you can use. just copy the CSS into your code: Example: #div { /* IE10 Consumer Preview */ background-image: -ms-linear-gradient(bottom, #FFFFFF 0%, #00A3EF 100%); /* Mozilla Firefox */ background-image:

I'm currently using the Hough Transform to get the straight lines. But there are a lot of lines detected. Can I know how to filter and only get the longest line from the output? HoughLinesP(dst, lines, 1, CV_PI/180, 50, 20, 10 ); //left lane for( size_t i = 0; i < lines.size(); i++ ) { Vec4i l = lines[i]; double theta1,theta2, hyp, result; theta1 = (l[3]-l[1]); theta2 = (l[2]-l[0]); hyp = hypot(theta1,theta2); line( cdst, Point(l[0], l[1]), Point(l[2], l[3]), Scalar(255,0,0), 3, CV_AA); } imshow("detected lines", cdst); } As far as I can see, you're literally a step away: The hypot function

I know the code for reading every line is f=open ('poem.txt','r') for line in f: print line how do you have python read only even-numbered lines from the original file. Assuming 1-based numbering of lines. There are quite a few different ways, here a simple one with open('poem.txt', 'r') as f: count = 0 for line in f: count+=1 if count % 2 == 0: #this is the remainder operator print(line) This also might be a little nicer, saving the lines for declaring and incrementing the count: with open('poem.txt', 'r') as f: for count, line in enumerate(f, start=1): if count % 2 == 0: print(line) From

I'm trying to think of a way to count the number of lines in a .csv file using Javascript, any useful tips or resources someone can direct me to? Depends what you mean by a line. For simple number of newlines, Robusto's answer is fine. If you want to know how many rows of CSV data that represents, things may be a little more difficult, as a CSV field may itself contain a newline: field1,"field two",field3 ...is one row, at least in CSV as defined by RFC4180 . (It's one of the aggravating features of CSV that there are so many non-standard variants; the RFC itself was very late to the game.) So

i am in situation where i want to draw lines one by one with some time period. I tried to do it by using thread.but it didnt work for me. The objective is i've 5 lines. the lines should be drawn one after one with 5seconds delay .Using Thread.sleep(5000) in onDraw() method but all the lines were drawn after 5seconds those were not drawn periodically...how can i draw lines periodically... code snippet:: public class PaintDemoActivity extends Activity { DragView drawView; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate
