DrawArcW
Draw the wide arc on the image window.
Format
DrawArc <x>, <y>, <radius>, <start>, <end>, <imageNo>[, <unitNo>]
Parameter
Return value
None.
Description
On the measurement image whose specified image number is in the <imageNo> parameter, draw a wide arc
of whose radius, width, starting angle, and ending angle are specified in the <radius>, <width>, <start>, and
<end> parameters respectively at the center coordinates specified in the <x> and <y> parameters.
Specify the corresponding Unit Macro processing unit number in the <unitNo> parameter to draw the image
at the position coordinates before applying position compensation. If the <unitNo> parameter is omitted, the
image is drawn at the position coordinates after applying position compensation.
In the <X> and <Y> parameters, specify the camera coordinates whose origin is at the upper-left corner of
the image.
In the <start> and <end> parameters, specify the angle so that the angle increases in a crockwise direction
respect to the positive X-axis of the camera coordinates.
Normally 0 should be specified in the <imageNo> parameter.
In the <unitNo> parameter, normally specify the processing unit number of the Unit Macro processing unit
that executes this process.
If an incorrect data type is specified for a parameter, a "Type mismatch" error will occur.
If a non-existent number, numerical value, or combination of data types or values are specified for a
parameter, an "Illegal function call" error will occur.
If a value outside the range -2147483648 to 2147483647 is specified as an integer parameter, an "Overflow"
error will occur.
If the format is written incorrectly, such as writing the macro function name incorrectly, omitting a comma, or
omitting a half-width space, a "Syntax error" error will occur.
Usage Cautions
• This macro function can only be used in the *MEASUREDISPI subroutine or the *MEASUREDISPG
subroutine. If used in another subroutine, an "Illegal function call" error will occur.
Parameter
name
Data type
Description
<x>
Integer type
The center X coordinate of the drawn wide arc
<y>
Integer type
The center Y coordinate of the drawn wide arc
<radius>
Integer type
Radius of the drawn wide arc
<start>
Integer type
Starting angle of the drawn wide arc
<end>
Integer type
Ending angle of the drawn wide arc
<width>
Integer type
Width of the drawn wide arc
<imageNo>
Integer type
Measurement image number to draw on (always 0)
<unitNo>
Integer type
Processing unit number to display the processing unit (0 to (the number of registered
processing units in the current scene minus one))
