How do I convert an HTML5 Canvas arc() to JavaFX Canvas arc()?

I wish to convert a statement from JavaScript used in an HTML5 Canvas such as:
ctx.arc(x, y, (rad+5)*factor, 0, Math.PI*2, true);
to the equivalent statement in JavaFX.
What would it look like?
For reference, in HTML5 Canvas the arc() method is defined as:
x
The x-coordinate of the center of the circle
Play it »
y
The y-coordinate of the center of the circle
Play it »
r
The radius of the circle
Play it »
sAngle
The starting angle, in radians (0 is at the 3 o'clock position of the arc's circle)
Play it »
eAngle
The ending angle, in radians
Play it »
counterclockwise
Optional. Specifies whether the drawing should be counterclockwise or clockwise. False=clockwise, true=counter-clockwise
but in JavaFX it is defined as:
public void arc(double centerX, double centerY, double radiusX, double radiusY, double startAngle, double length)
Adds path elements to the current path to make an arc that uses Euclidean degrees. This Euclidean orientation sweeps from East to North, then West, then South, then back to East.
Parameters:
centerX - the center x position of the arc.
centerY - the center y position of the arc.
radiusX - the x radius of the arc.
radiusY - the y radius of the arc.
startAngle - the starting angle of the arc in the range 0-360.0
length - the length of the baseline of the arc.
Could someone please show me what the JavaFX arc() statement would look like and explain how to convert between these two?
Thanks.

No conversion possible. Are you on a responsive project perhaps? Then
output is only HTML, mobile devices do not support Flash.

    You want to convert it to an array of what? Of numbers? Of LabVIEW colors?
    The "Read BMP File.vi" VI outputs a 1-D array of the pixels, but I suspect it is not exactly in the format that you need. I am NOT sure, but I think that each group of 3 elements of that 1-D array (which is inside the cluster "image data" that the VI outputs) represents the red, green and blue levels of a single pixel (but it may be hue, saturation and lum.). Also, since it is a 1-D array, you would have to divide it by the width (which is also included in the "image data" cluster) to get some sort of 2-D array of data.
    You can find the "Read BMP File.vi" VI in the functions palete> "Graphics & sound">"Graphics Formats".

  • How can I convert a mov file to swf?

    how can I convert a mov file to swf?

    You don't. You convert your mov file to a mp4 h264 encoded file, and import that into Flash. Then export to swf (in a folder), and you use that swf in your page (do not forget to upload all the other assets as well).
    Alternatively, convert to html 5 video files which are also supported by mobile devices.
    Learn more here: http://diveintohtml5.info/video.html
    ps you can use the Adobe Media Encoder to convert your mov files to h264. Or to html5 video:

  • I need to convert PDF file to Word Document, so it can be edited. But the recognizing text options do not have the language that I need. How I can convert the file in the desired of me language?

    I need to convert PDF file to Word Document, so it can be edited. But the recognizing text options do not have the language that I need. How I can convert the file in the desired of me language?

    The application Acrobat provides no language translation capability.
    If you localize the language for OS, MS Office applications, Acrobat, etc to the desired language try again.
    Alternative: transfer a copy of content into a web based translation service (Bing or Google provides a free service).
    Transfer the output into a word processing program that is localized to the appropriate language.
    Do cleanup.

  • How can I convert an InputStream to a FileInputStream ???

    How can I convert an InputStream to a FileInputStream ???

    Thanks for you reply, however, I am still stuck.
    I am trying to convert my application (which runs smoothly) to a signed applet. The following is the original (application) code:
    private void loadConfig() {
    String fileName = "resources/groupconfig";
    File name = new File(fileName);
    if(name.isFile()) {
    try {
         ObjectInputStream in = new ObjectInputStream(new FileInputStream(fileName));
         pAndGConfig = (PAGroupsConfig)in.readObject();
         in.close();
         return;
    } catch(ClassNotFoundException e) {
         System.err.println("++ERROR: "+e);
    } catch(IOException e) {
         System.err.println("++ERROR: "+e);
    System.out.println("Can't find file: " + fileName);
    Because all code and resources now reside in a Jar file (for the signed applet), I must use the following line to access the resources:
    InputStream is = this.getClass().getResourceAsStream(fileName);
    I then need to convert the 'InputStream' to 'ObjectInputStream' or 'FileInputStream' so that I can work with it.
    I would be very grateful if you could help shed some light on the matter - Cobram

    In your case you can only restore from a backup that has been created with the same iOS version. An iPhone 4 can only run 7.1.2, and, unless your iPhone 5 did not run the same version, you can't use a newer iOS backup of the 5 on the iPhone 4

  • I want to remove the monitor from my 17" Macbook Pro 2008 to use as an external for my Macbook Pro 15" 2012. How can I convert lvds to Thunderbolt and power the monitor?

    I want to remove the monitor from my 17" Macbook Pro 2008 to use as an external for my Macbook Pro 15" 2012. How can I convert lvds to Thunderbolt and power the monitor?

    It's almost impossible.  The new iMacs have a Target Display Mode, but it's built to do that.  Without ripping your screen out, finding an acceptable power supply, frame, and whatever electronics to convert a Thunderbolt signal to the screen, the cost will be much larger than buying a cheaper HiDef monitor that runs with an HDMI to Thunderbolt cable to your MacBook 15.  In fact, you can sell your 17" MBP for a lot of money, unless it's broken or something, buying you a really sweet monitor.
    By the way, I found your answer by searching this forum.  I would suggest using the search function here in the futuere.

  • How can I convert an array off byte into an Object ?

    Hi folks...

    How can I convert an array off byte ( byte[] ) into an Object using MIDP 2.0 / CLDC 1.1 ?
    I found on the web 2 functions that made this... but it uses a ObjectOutputStream and ObjectInputStream classes that is not provided by the J2ME plataform...
    How can I do this ?
    Waiting answers
    Rodrigo Kerkhoff

    There are no ObjectOutputStream and ObjectInputStream classes in CLDC. You must know what you are writing to and reading from the DataStream. You should write the primitives like int, String to the DataOutputstream at one end and read those in exactly the same sequence at the outher end using readInt(), readUTF() methods.
