Indicator looks fuzzy

[habibalex]

I made some updates to one of my indicators and the lines all appear to be 'fuzzy' now. Is there anything that would cause this?

I"m using OnRender to do the plotting. Has this issue occurred before in other indicators?

RenderTarget.AntialiasMode ?

Hello habibalex,

Testing on my end, I am finding that the rendering is the same.

Attached is a test script I've made.

The OrangeRed line is using SharpDX.Direct2D1.AntialiasMode.Aliased and has a jagged edge.
The Brown line is using SharpDX.Direct2D1.AntialiasMode.PerPrimitive and has a smoothed edge.

Does either line look fuzzy as well?

May I have a screenshot of you testing this test script to compare with my screenshot?

It's not so much that the line is jagged, it that the chart looks fuzzy. Take a look at the picture below. The top image looks nice and crisp, but the image behind it looks fuzzy.

I've narrowed it down to a custom drawing object

edit: I have a function setData in my custom drawing shape which has a called when I loop through all the DrawingObjects in my indicator's OnRender method. It then calls the shape's OnRender method to update itself.

Indicator #OnRender() => shape #setData() => shape #OnRender()

If I comment out the shape #OnRender() the crispness of the image comes back. If I leave it in, as soon as I complete the 2nd MouseUp to draw the final point of the custom rectangle, it gets fuzzy again.

Hello habibalex,

What is the AntialiasMode used?

Is there opacity with the drawn line?

Is it still fuzzy if there is no opacity?

I had to add the following to the OnRender method in my custom shape to fix the problem. Thanks for the help.

RenderTarget.AntialiasMode = SharpDX.Direct2D1.AntialiasMode.Aliased;
