Graphical output HP Prime

[Powersoft]

Try to output an Arc to the graphical screen with this code

HAngle:=0; //Degree
RECT_P(0,0,319,239,RGB(255,255,255);
ARC_P(0,159,119,50,40,90,RGB(0,0,0);
HAngle:=1; //Radians

The intension is to draw a arc starting at 40 Degree->90 Degree

What is doing wrong.

- some missing brackets?
- HAngle seems to be ignored. The manual is probably not correct: "a1 and a2 follow the current angle mode and are optional. The default is a full circle."

Code:

EXPORT tst()
BEGIN
  HAngle:=0; //Degree
  local arc:=π/180;
  RECT_P(0,0,319,239,RGB(255,255,255));
  ARC_P(159,119,1,RGB(0,0,255));
  ARC_P(159,119,48,RGB(0,0,255));
  ARC_P(159,119,50,40*arc,90*arc,RGB(0,0,0));
  HAngle:=1; //Radians
  WAIT();
END;

The values for HAngle are inverted: 0 = Radians mode
1 = Degrees mode

You can directly test this via the HOME command line. It is shown otherwise in user guides, and has been reported for change.

Code:


EXPORT tst()
BEGIN
  HAngle:=1; //Degree
  RECT();  
  ARC_P(159,119,50,40,90,RGB(0,0,0));
  HAngle:=0; //Radians
  freeze;
END;

Hello Dale,
Thanks for the clarification! I didn't check the docs.
Once again, the community is very valuable.
