SharpDX BitmapBrush in OnRender

[NicholasJoannette]

I'm trying to use a SharpDX BitmapBrush to fill an ellipse in OnRender. The error I get is:

"Chart rendering failed. There is likely a problem with a chart object's OnRender method. D2D error = 'HRESULT: [0x80070057], Module: [General], ApiCode: [E_INVALIDARG/Invalid Arguments], Message: The parameter is incorrect."

in the log.

If I use RenderTarget.DrawBitmap(), I can see the image and draw it on the chart - so the loading of the bitmap is not the problem.

For example, trying to create a bitmap brush and fill a rectangle with it using the following code will reproduce the error:

BitmapBrush bitmapBrush = new BitmapBrush(RenderTarget,myBitmap);
SharpDX.RectangleF rect = new SharpDX.Rectangle(0,0,50,50);
RenderTarget.FillRectangle(rect,bitmapBrush);

Are bitmap brushes not possible - or am I missing something crucial, or an easier solution? I looked into ImageBrush as well. I just want to be able to fill and texture geometries on the chart with a loaded image file.

Hello NicholasJoannette,

Thank you for your post.

The following works for me to create a bitmap brush and use it to fill an ellipse:

SharpDX.Direct2D1.BitmapBrush myBitmapBrush = new SharpDX.Direct2D1.BitmapBrush(RenderTarget, myBitmap);

RenderTarget.FillEllipse(new SharpDX.Direct2D1.Ellipse(new SharpDX.Vector2((float)ChartPanel.W / 2, (float)ChartPanel.H / 2), 10, 10), myBitmapBrush);

myBitmapBrush.Dispose();

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

Thanks so much for the help. I was actually making an error elsewhere. Very appreciated!
