Custom Render - Example

[neoikon]

I feel I am trying to do something similar to this conversation, so I'm posting this here.

I'm wanting to use the appearance of a Plot[], to use as the basis when formatting a RenderTarget.DrawLine() line.

Something like this:

RenderTarget.DrawLine(p0.ToVector2(), p1.ToVector2(), Plots[0].BrushDX, Plots[0].Width, Plots[0].StrokeStyle); 

But, that doesn't give the same output as the plot (close, but not if dashed, dotted, etc). As mentioned above, the StrokeStyle object may be a little simplier than the RenderTarget is needing.

Is there a way around this? Can I get a DashStyleHelper object from the Plot, create a StrokeStyle object, then pass that to DrawLine()?

Like this (but actually pulling information from Plot[])

StrokeStyle strokeStyle = new Stroke(Brushes.Gray, DashStyleHelper.Dot, 5f).StrokeStyle;
RenderTarget.DrawLine(p0.ToVector2(), p1.ToVector2(), Plots[0].BrushDX, Plots[0].Width, strokeStyle); 

Any help is greatly appreciated!

Hello neoikon,

As these are different types of objects, the properties are not the same type of properties.

I am not aware of a way to convert these, however, I am checking with our development to see if they know of a way.

I appreciate your patience.

Thanks! To be clear, I'm not talking about converting, but determining enough formatting information from the Plot() object to create required formatting objects to make a RenderTarget.DrawLine() look the same as the Plot.

Hello neoikon,

Have I must understood your inquiry.

Are you not trying to use the DashStyleHelper from a plot as the SharpDX.Direct2D1.DashStyle for a rendered object?

If so, I was referring to converting the DashStyleHelper to SharpDX.Direct2D1.DashStyle.

If this is what you are looking for you can use an if statement and choose the correct dashstyle, but we have not found a way to convert one type to the other type.

SharpDX.Direct2D1.DashStyle useDashStyle;

if(Plots[0].DashStyleHelper.ToString() == "Solid")
{
useDashStyle = SharpDX.Direct2D1.DashStyle.Solid;
}


If you are not wanting to use the DashStyleHelper from a plot as the DashStyle for SharpDX object, can you clarify what you are trying to do?

As I mentioned, "determine enough formatting information from the Plot() object to create required formatting objects to make a RenderTarget.DrawLine() look the same as the Plot."

RenderTarget.DrawLine() accepts a StrokeStyle (not a DashStyle nor a PlotStyle).

DashStyleHelper is not enough, since it could also have a PlotStyle of "TriangleUp" or "Cross" or some other appearance.

Hello neoikon,

What further information are you needing to be able to create the StrokeStyle or object?

The plots also have a StrokeStyle object.
Plots[0].StrokeStyle.DashStyle
Plots[0].StrokeStyle.DashOffset

Using the if statement to select the DashStyle for the new StrokeStyle as well as the Plot[0].Width and the Plots[0].Brush or BrushDX, you should have the dash style the width and the color..
