I had it working and now it doesn't!

[Mindset]

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

blockstring.Append(String.Format("({0})", "Hello"));

SharpDX.Direct2D1.Brush textBrushDx;
Brush textBrush = ChartControl.Properties.AxisPen.Brush;

textBrushDx = textBrush.ToDxBrush(RenderTarget);


SharpDX.DirectWrite.TextFormat textFormat1 = subFont.ToDirectWriteTextFormat();
// blockstring.Clear();
SharpDX.DirectWrite.TextLayout textLayout1 = new SharpDX.DirectWrite.TextLayout(NinjaTrader.Core.Gl obals.DirectWriteFactory,
blockstring.ToString(), textFormat1, ChartPanel.X + ChartPanel.W,
textFormat1.FontSize);//this binds it to the ChartPanel space ONLY

SharpDX.Vector2 textPoint = new SharpDX.Vector2(ChartPanel.X-30 + (ChartPanel.W/2),ChartPanel.Y );

RenderTarget.DrawTextLayout(textPoint, textLayout1, textBrushDx, SharpDX.Direct2D1.DrawTextOptions.NoSnap);


textLayout1.Dispose();
textBrushDx.Dispose();
textFormat1.Dispose();
RenderTarget.AntialiasMode = oldAntialiasMode;

Spent 2 hours on this - had it working and now just can't get it to display - please tell me where I am going wrong.

thanks

Hello Mindset,

Thanks for your post.

The script may not have a string in blockstring that would be visible, or the brush that is being used is transparent.

You can hard code a brush and a string in your code to verify that the code is working properly when there is a definite string and brush given.

For example, you could check your code with a hard coded brush and string as follows:

protected override void OnRender(ChartControl chartControl, ChartScale chartScale)
{
    SharpDX.Direct2D1.AntialiasMode oldAntialiasMode = RenderTarget.AntialiasMode;
    RenderTarget.AntialiasMode = SharpDX.Direct2D1.AntialiasMode.Aliased;

    SharpDX.Direct2D1.Brush textBrushDx;
    System.Windows.Media.Brush textBrush = Brushes.Orange;

    textBrushDx = textBrush.ToDxBrush(RenderTarget);


    SharpDX.DirectWrite.TextFormat textFormat1 = ChartControl.Properties.LabelFont.ToDirectWriteTex tFormat();

    SharpDX.DirectWrite.TextLayout textLayout1 = new SharpDX.DirectWrite.TextLayout(NinjaTrader.Core.Gl obals.DirectWriteFactory,
    "Test", textFormat1, ChartPanel.X + ChartPanel.W,
    textFormat1.FontSize);//this binds it to the ChartPanel space ONLY

    SharpDX.Vector2 textPoint = new SharpDX.Vector2(ChartPanel.X-30 + (ChartPanel.W/2),ChartPanel.Y );

    RenderTarget.DrawTextLayout(textPoint, textLayout1, textBrushDx, SharpDX.Direct2D1.DrawTextOptions.NoSnap);


    textLayout1.Dispose();
    textBrushDx.Dispose();
    textFormat1.Dispose();
    RenderTarget.AntialiasMode = oldAntialiasMode;
}

We look forward to assisting.

Thanks Jim
I am trying to get different texts with different colours.
Where am I going wrong here - looks simple enough?

if (ChartBars == null)
return;
int txtHeight = (int)subFont.TextFormatHeight; // (int)graphics.MeasureString("X", txtFont).Heig

//Anti alias lines
//Append to stringbuilder
// Declare BrushDx
//place text Brush to DXBrush
//textlayout declaration
//Vector 2 text point
//Dispose

ChartPanel panel = chartControl.ChartPanels[chartScale.PanelIndex];
SharpDX.Direct2D1.AntialiasMode oldAntialiasMode = RenderTarget.AntialiasMode;
RenderTarget.AntialiasMode = SharpDX.Direct2D1.AntialiasMode.Aliased;



SharpDX.Direct2D1.Brush textBrushDxW;
SharpDX.Direct2D1.Brush textBrushDxG;
Brush textBrush = Brushes.White;//Brushes.AliceBlue;//ChartControl.Properties.AxisPen.Brush;
Brush textBrushGreen = Brushes.Chartreuse;
// areaBrushDx = areaBrush.ToDxBrush(RenderTarget);
textBrushDxW = textBrush.ToDxBrush(RenderTarget);
textBrushDxG = textBrush.ToDxBrush(RenderTarget);


SharpDX.DirectWrite.TextFormat textFormat1 = subFont.ToDirectWriteTextFormat();

///White
SharpDX.DirectWrite.TextLayout textLayoutwhite = new SharpDX.DirectWrite.TextLayout(NinjaTrader.Core.Gl obals.DirectWriteFactory,
whitestring.ToString(), textFormat1, ChartPanel.X + ChartPanel.W,
textFormat1.FontSize);//this binds it to the ChartPanel space ONLY

///Green
SharpDX.DirectWrite.TextLayout textLayoutgreen = new SharpDX.DirectWrite.TextLayout(NinjaTrader.Core.Gl obals.DirectWriteFactory,
greenstring.ToString(), textFormat1, ChartPanel.X + ChartPanel.W,
textFormat1.FontSize);//this binds it to the ChartPanel space ONLY


SharpDX.Vector2 textPoint = new SharpDX.Vector2(ChartPanel.X-30 + (ChartPanel.W/2),ChartPanel.Y );

RenderTarget.DrawTextLayout(textPoint, textLayoutwhite, textBrushDxW, SharpDX.Direct2D1.DrawTextOptions.NoSnap);
SharpDX.Vector2 textPoint2 = new SharpDX.Vector2(ChartPanel.X-30 + (ChartPanel.W/2),ChartPanel.Y+txtHeight );
RenderTarget.DrawTextLayout(textPoint2, textLayoutgreen, textBrushDxG, SharpDX.Direct2D1.DrawTextOptions.NoSnap);


textLayoutwhite.Dispose();
textLayoutgreen.Dispose();
textBrushDxW.Dispose();
textBrushDxG.Dispose();

//areaBrushDx.Dispose();
textFormat1.Dispose();
RenderTarget.AntialiasMode = oldAntialiasMode;

Oh I forgot to change the Brush - Jeez!!
