areaOpacity Rectangle not uniform color and wrong opacity output

[PaulMohn]

I have the following:

if (State == State.SetDefaults)
{
...
ColorRA = Brushes.Cyan;
...
RAOpacity= 30;

---

protected override void OnBarUpdate()
{
...
Draw.Rectangle(this, "RA"+CurrentBar, false, barsAgo, Highs[0][HighestBar(High, barsAgo)], 0, Lows[0][LowestBar(Low, barsAgo)], Brushes.Transparent, ColorRA, RAOpacity);


---

[NinjaScriptProperty]
[XmlIgnore]
[Display(Name="RA Region", Description="Color for painted region", Order=0, GroupName="01. Regions Colors")]
public Brush ColorRA
{ get; set; }

[Browsable(false)]
public string ColorRASerialize
{
get { return Serialize.BrushToString(ColorRA); }
set { ColorRA= Serialize.StringToBrush(value); }
}


---

[NinjaScriptProperty]
[Range(1, int.MaxValue)]
[Display(Name="Rectangle Opacity", Description="Opacity of region", Order=1, GroupName="02. regions Opacities")]
public int RAOpacity
{ get; set; }


The output is as this


What's preventing the correct opacity to display?

I looked at the documentation and multiple forum threads but no solution found.

I also tested with
[Range(0, 100)]

does not solve it.

Hello PaulMohn,

Thank you for your post.

What is the result in the NinjaScript Output window if you add a print of the value for RAOpacity?

https://support.ninjatrader.com/s/article/Developer-Guide-Debugging-using-Print-and-TraceOrders?language=en_US

This should let you know what value is being used for RAOpacity, and since you have it as a user input you could even test changing the opacity from the indicator settings and seeing if the prints reflect the change.

Please let us know if we may be of further assistance.

Prints output

RAOpacity 30

upon editing 70 to 30 value and applying in the indicator properties on the chart.

What is the solution suggestion you know of?

Based on this information, it seems that you changed it from 70 to 30 and the output value was 30, correct? If that is the case, I do not understand what you are trying to resolve. If you set it to a different value, such as 100, does it print out a value of 100 and have no opacity? Then, if you change it to 0 does it print out and become fully see through?

I look forward to your clarification.

The documentation states :
areaOpacity
Sets the level of transparency for the fill color. Valid values between 0 - 100. (0 = completely transparent, 100 = no opacity)

https://ninjatrader.com/support/helpGuides/nt8/draw_rectangle.htm

When Ctrl+i on the chart the output window prints as 1st print
State: SetDefaults

100 value
Prints: RAOpacity 100


1 value
Prints: RAOpacity 1


0 value
Prints: RAOpacity 0



30 value
Prints: RAOpacity 30


What is the solution to get the output uniform opacity?

Thank you for your reply.

Since you are using the tag "RA"+CurrentBar I suspect that what you are seeing is multiple rectangles being drawn with different opacities; is your desired behavior to draw only one rectangle? If so, you should use one tag only and that way the draw object will be modified each time Draw.Rectangle() is called with that same tag. Otherwise, each time you call your logic with "RA"+CurrentBar then a new rectangle is drawn.

That was the solving suggestion. Good elucidation. Thank you.

Draw.Rectangle(this, "RA", false, barsAgo, Highs[0][HighestBar(High, barsAgo)], 0, Lows[0][LowestBar(Low, barsAgo)], Brushes.Transparent, ColorRA, RAOpacity);

The +CurrentBar was drawing a new rectangle on each new bar within the rectangle region bounds.
