#1 applet param FPS

[Georg Berndt]

when i start the applet with FPS such like 0.1

i get this errormessage

java.lang.NumberFormatException: For input string: ".1"
at java.lang.NumberFormatException.forInputString
(NumberFormatException.
java:48)
at java.lang.Integer.parseInt(Integer.java:468)
at java.lang.Integer.parseInt(Integer.java:518)
at WebCamApplet.init(WebCamApplet.java:28)
at sun.applet.AppletPanel.run

at WebCamApplet.stop(WebCamApplet.java:41)
at sun.applet.AppletPanel.run
(AppletPanel.java:440)
at java.lang.Thread.run(Thread.java:534)

if you change WebCamApplet.java:28
form
int defFPS = Integer.parseInt(this.getParameter("FPS"));
in
double defFPS = Double.parseDouble(this.getParameter
("FPS"));

and ImageCanvas.java:58
in
public ImageCanvas(Applet applet, String host, int port,
double fps, int width, int height) {

is works..

sorry for my bad english.. ;)
