draw

Is it possible to draw user-defined grid lines with defined points at all intersections, against the output of the color detection sample in the OpenCV sample file? Basically, the webcam will need to be detecting human head and shoulders from above you. Then when a person is detected, I need the grid lines to be there so that I am able to know from which outermost grid (left shoulder), to the next outermost grid (right shoulder), in both x and y axis (forehead and back of head). Thereafter, these points have to be sent for operation of mechanical parts like actuator and valves. I'm an entry

I am using python graph-tool. To draw graphs, it uses graph_draw function . I want to send vertex positions explicitly to dot engine. It turns out that I can pass a property map named pos . I tried defining it as v_pos = g.new_vertex_property("vector<double>") where g is my graph. I am not sure if it is the right way to do it. There is one code snippet which you might find helpful. pos = gt.random_layout(g, shape=shape, dim=3) >>> pos[g.vertex(0)].a array([ 86.59969709, 1.31435598, 0.64651486]) graph_draw(g, pos=pos, output="graph-draw-random.pdf") What should I do if I were to define my

My problem is that I need to draw text on a monochrome bitmap. The resulting bitmap has to be printed on a thermal POS printer, so the bitmap has to be 1bpp. I'm not good in graphics, so I've tried to find some samples. Here's what I've tried: Bitmap bmp = new Bitmap(300, 300, PixelFormat.Format1bppIndexed); using (Graphics g = Graphics.FromImage(bmp)) { Font font = new Font("Arial", 20, FontStyle.Bold, GraphicsUnit.Point); g.Clear(Color.White); g.DrawString(text, font, Brushes.Black, 0, 0); } bmp.Save(@"c:\x\x.bmp", ImageFormat.Bmp); the Save at the end was just to check the result. With this

The method I am trying to use is the: drawImage(image, int, int, int, int, ImageObserver) method so that i can scale my image, on all the examples i've seen the ImageObserver should be this, but this doesn't seem to work(i.e. the only methods i have seen is: drawImage(image, int, int, ImageObserver), don't know if this makes a difference). Here is my main class that is the applet: import java.applet.*; import java.awt.*; public class Main extends Applet implements Runnable{ private Thread th; private Hitter hitter; //double buffering private Graphics dbg; private Image dbImage; public void

I have this xml : <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/photo0" android:id="@+id/imagBackground"> <TextView android:layout_width="20dip" android:layout_height="20dip" android:layout_marginLeft="250dip" android:layout_marginTop="15dip" android:background="#FFFFFF" android:id="@+id/index" android:text="0" android:textColor="#000000"> </TextView> <ImageView android:layout_marginTop="280dip" android:layout_width="fill_parent" android

I am new to android, i have managed to write code that displays the google map, i can able to give source and destination addresses and place push pin over there using reverse Geocode concept... the scenario is i want to display the driving,walking,bicycling directions from source to destination point with displaying a line from source to destination.. Peter Knego AFAIK there is no route calculation functionality in Google Maps for Android. Furthermore, live route calculations for navigation are not allowed by Google Maps terms of service , article 8.7. For alternative approach take a look at:
