Use of LineMetrics

[bubblegum]

Hi, I'm trying to place lines of 'random' length text next to each other horizontally. Each piece of text is a different color so (I assume) it can't be one text object. So I'm trying to work out the width of each piece of text so that I can place the next text without overlapping the previous one. I'm assuming I need to use 'LineMetrics' but I can't find any examples. I'd appreciate an example. So in my example code below, how do I set textOffset1, 2 and 3 automatically? Thanks

        protected override void OnRender(ChartControl chartControl, ChartScale chartScale)
        {
            base.OnRender(chartControl, chartScale);

            // define the point for the text to render
            SharpDX.Vector2 startPoint = new SharpDX.Vector2(ChartPanel.X, ChartPanel.Y + 20);

            // construct the text format with desired font family and size
            SharpDX.DirectWrite.TextFormat textFormat = new SharpDX.DirectWrite.TextFormat(Core.Globals.DirectWriteFactory, "Arial", 12);

            int textOffset1 = 5;
            int textOffset2 = 25;
            int textOffset3 = 45;

            // construct the rectangleF struct to describe the position and size the text
            SharpDX.RectangleF rectangleF1 = new SharpDX.RectangleF(startPoint.X + textOffset1, startPoint.Y, ChartPanel.W, ChartPanel.H);
            SharpDX.RectangleF rectangleF2 = new SharpDX.RectangleF(startPoint.X + textOffset2, startPoint.Y, ChartPanel.W, ChartPanel.H);
            SharpDX.RectangleF rectangleF3 = new SharpDX.RectangleF(startPoint.X + textOffset3, startPoint.Y, ChartPanel.W, ChartPanel.H);


            // define the brush used for the text
            //SharpDX.Direct2D1.SolidColorBrush customDXBrush1 = new SharpDX.Direct2D1.SolidColorBrush(RenderTarget, SharpDX.Color.Blue);
            //SharpDX.Direct2D1.SolidColorBrush customDXBrush2 = new SharpDX.Direct2D1.SolidColorBrush(RenderTarget, SharpDX.Color.Red);
            //SharpDX.Direct2D1.SolidColorBrush customDXBrush3 = new SharpDX.Direct2D1.SolidColorBrush(RenderTarget, SharpDX.Color.Yellow);

            // execute the render target text command with desired values
            RenderTarget.DrawText(myText1, textFormat, rectangleF1, customDXBrush1);
            RenderTarget.DrawText(myText2, textFormat, rectangleF2, customDXBrush1);
            RenderTarget.DrawText(myText3, textFormat, rectangleF3, customDXBrush1);


            // always dispose of textFormat when finished
            textFormat.Dispose();

            // always dipose of brush when finished
            customDXBrush1.Dispose();
            customDXBrush2.Dispose();
            customDXBrush3.Dispose();
        }

Hello bubblegum,

Thank you for your post.

You could use TextLayout and TextLayout.Metrics. This section of the help guide should point you in the correct direction:
